Description

The large-scale floating structure waterborne of high safety
Technical field
Floating structure waterborne is the utility model is related to, more particularly to a kind of new-type high safety do not disintegrated, do not turned over and sunk Large-scale floating structure waterborne.
Background technology
The large-scale floating structure waterborne of so-called high safety, refer to that ship and ocean platform than routine have higher safety Property, on the premise of to ensure floating structure self structure and thereon human life's safety, there is provided equipment carry ability it is bigger, A large amount of personnel are resident, huge amounts of material is deposited and the floating structure of working space more greatly main purpose, such as marine comprehensive coverage base Ground, ocean exploitation community, maritime travel amusement platform, offshore industry center etc..
Face one of large-scale floating structure waterborne exploitation is great it is a key issue that with the increase of floating structure yardstick, Existing for script " conditional security performance " become it is increasingly complex, be more difficult to predict, especially in the condition for thering are a large amount of personnel to be resident Under, once there is accident, consequence is more difficult to bear.
Maritime safety generally can be divided into following two class shapes or system：1st, the structure safety of offshore structures, structure safety Refer to that the structure of works still keeps complete, firm ability under the effect of various external force, pay close attention to structure Strong degree, anti-tired Labor, anti-heavy and stability etc.；2nd, the safety of life at sea, for the purpose of ensureing personnel's life security, pay close attention to subdivision, stability, Electromechanical equipment, prevent fires, escape lifesaving and wireless telecommunications etc..
Most important two problems that the large-scale floating structure waterborne of high safety needs to solve can be summarized as：It is " waterborne floating The security (structural strength, stability etc.) of formula structure itself and floating structure waterborne carry security (personnel's life of personnel Order the minimum living guarantee of safety and escape rescue action etc.) ".It is intended that by the progress and development of technology, can realize The large-scale reliable safety forecast of floating structure.Meet with foreseeable least favorable sea situation and there is the worst of record to touch Hit, hit a submerged reef, be stranded, goods displacement etc. extremely is under the conditions of Crash characteristics, structure itself and personnel are able to ensure that safety thereon, carry The high security that can not be ensured for current large-scale floating structure waterborne.
In the prior art, can stablize in marine environment, one of large-scale floating structure waterborne survived in storm It is central drainage type ship.It uses common flood line-surface structure, and its buoyancy is provided by the empty cabin concentrated, need in order to anti-heavy Using subdivision measure, but because most of empty cabins are simultaneously " function cabins " so subdivision can not possibly be too close.Its principal dimensions design master Consider to be applied to load-carrying and navigation, for argosy ship, molded breadth degree is typically not greater than 50 meters.And in marine environment, it is possible to About 30 meters of the maximum wave height of appearance, corresponding about 500 to 600 meters of maximum wavelength (T ≈ 20s), in fact it could happen that maximum wave steepness about 1/7.By taking conventional large ship as an example, about 50 meters of maximum molded breadth, about 60 meters of moldeed depth, about 35 meters of height of C.G., when ship is in stormy waves Power failure occurs in environment, can cause to lose the speed of a ship or plane and bow to control ability, Transverse wave-like states now necessarily occur, produce therewith Now huge lateral oscillation is born, may cause the danger toppled occur.
Ship causes ship to topple or sink it may also happen that collide, hit a submerged reef, be stranded, the contingency such as displacement of goods, past It is on the hazard safely toward the human life made on ship.For example, on January 13rd, 2012, " song poem reaches Concorde " cruise is taken notice of greatly Li Yin, which hits a submerged reef, to be caused to topple, and causes 32 people dead.On 2 3rd, 2006, Egyptian " A Ersa Farnhams win casio 98 " visitor Wheel sinks in Red sea waters, causes 190 people wrecked, nearly 800 people is missing.On September 26th, 2002, Senegal's " Qiao's drawing number " inclines Cover, cause dead more than 700 people.
In addition, existing large-scale floating structure waterborne also has semisubmersible platform, also known as column stablized unit.If American is on sea Upper tender is in the patent of invention of China, Publication No. CN1269759A.It simply equals conventional offshore oil semi-submersible type Platform structure type maximizes.Because the body of floating downward of semi-submersible structure is located at away from the water below horizontal plane certain depth, Yi little Shui The floating body in line face (because the natural heaving period of small-waterplane-area floating body is more than the spectral peak cycle of ocean wave, is not easy humorous from each other Shake, so, making it have preferable sea-keeping and attitude stability) stretching couples column with the scope of operation upwards.Its scope of operation is located at More than the height more than adaptation waters maximum wave height, thus make total height of the platform from floating body to the scope of operation very big, it is huge It is big and heavy, build and use cost is very high, meanwhile, its drinking water is very deep, and wet structure ratio is very big.It is unsuitable for shallower in depth Waters uses.Determine that its drinking water and variation of the posture to load are very sensitive by the principle of column attitude stabilization, small load is disturbed Dynamic platform to be caused significantly to wave, small load change will cause platform significantly to rise and fall or tilt.So it must match somebody with somebody Put complexity ballast and corresponding control system (ballast tank is indispensable, its ballast tank for semisubmersible platform Capacity is much larger than maximum variable operating load), whether are the integrality and normal operation of ballast and corresponding control system There is fatal influence to the security of platform.This structure be in the petroleum industry below 130 metrical scales it is feasible, when for During the large-scale floating structure that hundreds of meters of yardstick, its efficiency and reliability are difficult to predict, the program is not put to be engineered so far Implement.State center of gravity when floating body emerges under semisubmersible platform is very high, and stability requirement is difficult to meet under high sea situation, is only applicable Shifting boat operation under low sea situation.
In addition, the overall structure form of semisubmersible platform is by lower float, middle standing pillar and superstructure cabin group Into its underpart floating body typically sets 2, and its column typically sets 4,6, at most sets 8.When the severe sea situation bar of generation When part causes local damage or unexpectedly collided, any one component damage, it may cause catastrophic consequence.Example Such as, morning nineteen eighty-two 2 month 15, in " ocean ranger " number drilling platforms of Canadian Newfoundland offshore oil field operation, meet with Speed per hour is up to the hurricane of 190km/h and high 20 meters of wave, is blown over sinking.There are tens of people to leap to marine escape during though, by It is that neighbouring two drilling platforms and other ships etc. are helpless in the late into the night in winter of cold again in violent hurricane, these People and 84 people altogether stayed on platform are all wrecked.On March 27th, 1980, " Alexandria bases are blue " number drilling platforms are met with Happen suddenly 9 grades of strong wind, and 6 meters of high billow are flutterred entrainment of ice cube to platform, and one in 5 pillars of platform is broken, and platform exists In 40 degree of inclinations in trembling.Only after 15 minutes, platform just sinks to seabed, causes 123 people wrecked.
The security of all kinds of large ships and large-scale floating structure platform why be all it is limited (including structure safety with Human life's safety).One of principal element is because their buoyancy is provided by the empty cabin concentrated, once unexpected break Damage, there is the risk toppled and sunk；In addition, metancenter height all very littles of most of large ships and ocean platform, it is unloaded and Very greatly, drinking water is very shallow when unloaded, and center of gravity is very high, and stability can not meet code requirement for drinking water change between fully loaded, it is necessary to Add the ballast Water Ballast of flood tide.Buoyancy module must have the function of cargo hold or ballast tank concurrently simultaneously, must not use Real core buoyancy module.Therefore, part damage can cause loss of buoyancy and stability to detract, and asymmetric buoyancy necessarily occurs in large scale damage Lose, cause to turn over and sink.In addition, hit a submerged reef, be stranded, bow has floating structure to incline to the contingency such as displacement extremely of out of control, goods The risk covered and turned over and sunk.
There is drawback in the structure overall security of ship and semisubmersible platform of the prior art, its failure mode is held Easily there is the chain reaction of vicious circle.Under extreme conditions, operating mode, the structure such as example collide, hit a submerged reef, be stranded and part occurs Damage, and then cause buoyancy loss, overall structure change of stress field and posture to change；Above-mentioned change will cause to aggravate into water, from And floating structure is caused integrally to produce more serious water inlet, stress variation and more severe posture；Said process persistent loop, Most cause floating structure integrally topple, be broken at last, disintegrate so that sinking.
In the prior art, the truss type platform of Mr.'s Yuan Xiaoji invention in also 2004, it is proposed that a kind of span is greatly, certainly Weight is small, can in operating environment it is stable, in high sea safety, structure and operation compared with it is simple, wave force is small, drift resistance Small floating structure waterborne, solves the technical barrier that floating structure waterborne can maximize.Its problem is, in the invention Operation at sea face and lower float rigidity of structure gap are larger so that the utilization rate of material is relatively low；Connection among in the invention Bar does not provide buoyancy so that the stability at large angle also existing defects under the stability of floating structure, especially extreme condition.
In the prior art, the safety of life at sea, pay close attention to subdivision, stability, electromechanical equipment, prevent fires, escape lifesaving and Wireless telecommunications etc..International convention is organized to set up by world maritime, made laws by signatories to a treaty's maritime sector, decree and specification are carried out Supervision.After the perils of the sea occurs, without exception be to be difficult to by original structure be that personnel are provided with the life security guarantee of effect, It can only place hope on and escape lifesaving appliance and method, according to all kinds of marine casualties (collide, hit a submerged reef, stranded, topple, sink) Statistics, wherein, successfully abandon ship and evacuation process in personnel it is missing and injures and deaths still occupy larger proportion, therefore, skill The development of art is wished to explore new-type high safety floating structure waterborne so that even if the perils of the sea occurs, structure can not topple, no in itself Sink and can continue to effectively provide the goods and materials for more ensureing minimum life condition for personnel thereon, so personnel can be with It need not abandon ship, in favor of sticking in need.
Since eighties of last century, scientific technological advance is rapid.It is same in terms of navigation, many new technologies, new equipment all on Ship, seagoing condition have obtained greatly improving.Various machines, the navigation instrument of ship are increasingly advanced.By reason In the case of, the safety of ship should be more secure, but true really not so, with the improvement of seagoing condition, global ship Not only oceangoing ship casualty is not controlled effectively, in rising trend on the contrary.Reason is many, wherein, human factor It account for very big ratio.According to statistics, in all marine accidents, about 80% has significant correlation, therefore, technology with human factor Development is wished to explore new-type high safety floating structure waterborne so that the security of floating structure to the dependence of crewman and manipulation compared with It is small, even if operational error and the accident of human factor occurs, also it is unlikely to cause catastrophic consequence, at least also ensuring will not Threaten the life security of personnel thereon.
Put it briefly, in the prior art, large-scale floating structure waterborne there are three kinds of typical technology candidate schemes.One is adopt With common central drainage type flood line-surface structure, such as large ship, its problem is the potential safety hazard such as topple, sink be present.Its Second, using scattered dewatering type small-waterplane-area structure, such as semisubmersible platform, its problem be from great, it is structurally and operationally more complicated, Cost is higher, poor in anticollision, damage stability etc. security.The third is using scattered dewatering type truss type platform, solve The problem of reduction seaway load is to realize floating structure " maximization ", but (collision, touched without solving extreme emergency conditions Reef, stranded etc.) under antidumping problem.As can be seen here, the development of large-scale floating structure technology waterborne is wished to explore new structure shape Formula, it is simple to operate, it is small by interference from human factor, it can ensure that structure itself is pacified under working condition and various unexpected factors Entirely, at the same can ensure accident occur after, personnel have enough living guarantee conditions thereon.
Generally, above-mentioned large ship of the prior art, semisubmersible platform, truss type platform, are meeting Under conditions of safety standard, there are still meet with foreseeable least favorable sea situation and having the worst of record to touch Hit, hit a submerged reef, be stranded, under the goods emergency conditions such as displacement extremely, personnel's life thereon is integrally toppled, sinks and how ensured to structure Order the hidden danger of safety.The high safety of large-scale floating structure how is deterministically realized, is a still unsolved global problem.
The content of the invention
A main purpose of the present utility model is at least one defect for overcoming above-mentioned prior art, there is provided Yi Zhonggao The large-scale floating structure waterborne of safety.While effectively reducing seaway load and extraordinary resistance to ripple stability is provided, improve Maltilevel security redundancy of the overall structure in terms of integrality, unsinkability and antidumping, in foreseeable extreme natural environmental condition Under extreme emergency conditions, the overall effective, floating waterborne for the high safety not sunk of not toppling of floating structure waterborne is still ensured that Structure.
Another main purpose of the present utility model is at least one defect for overcoming above-mentioned prior art, there is provided a kind of The large-scale floating structure waterborne of high safety.So that the operation and manipulation of floating structure are relatively easy, human factor causes accident Potential safety hazard is less, is also unlikely to cause the catastrophic effect for threatening personnel's life security even if related accidents occur.
Another main purpose of the present utility model is at least one defect for overcoming above-mentioned prior art, there is provided a kind of The large-scale floating structure waterborne of high safety.Even in the foreseeable least favorable sea situation of experience and there is the worst of record to touch Hit, hit a submerged reef, be stranded, under the goods emergency conditions such as displacement extremely, the personnel carried can also rely on waterborne floating without abandoning ship Formula structure in itself, still is able to effectively continue as personnel thereon and provides living guarantee condition than abandoning ship safer.
The utility model embodiment proposes a kind of large-scale floating structure waterborne of high safety, including lower float structure, on Portion's structure and intermediate connection structure；The lower float structure includes the single floating body of five and more than five, each floating body interval Certain distance；The lower float is in super large Area of Water Plan form, and at least partly outside floating body uses class reality core buoyancy module；The class The displacement of volume sum of real core buoyancy module is more than the equivalent water volume of the floating structure full load full weight；The superstructure is framework Structure or body structure；The intermediate connection structure is arranged in spatial dispersion, including is intersected with horizontal plane and provided safety The structure of restoring force；The intermediate connection structure is interconnected to whole with the superstructure and the lower float structure Body；The minimum distributed dimension of the lower float structure outline in the horizontal direction is equal to or more than the large-scale of the high safety 4 times of centroidal distance standing level height during above-water large-scale floating structure zero load.
According to an embodiment, the outer profile size of the lower float structure is at least more than 140 meters in one direction.
According to an embodiment, the profile height size of any one floating body in the lower float structure, which is less than, to be applicable The 1/2 of the maximum wave height size in waters.
According to an embodiment, the class reality core buoyancy module uses the buoyancy module structure of internal high density subdivision, and/or institute State light filling material water-proof material or the removable lightweight material water-proof material of assembling in class reality core buoyancy module.
According to an embodiment, under full-load draft state, the waterline of the floating body in the lower float structure outline The area ratio of area and float structure outline is not more than 0.7.
According to an embodiment, the overall any direction in level of structure of the floating structure is across 4 or 4 Span above.
According to an embodiment, forming between each component and/or part of the intermediate connection structure has level side To the connecting elements and/or connection member of arrangement.
According to an embodiment, the outer member of the intermediate connection structure uses class reality core buoyancy module structure.
According to an embodiment, the floating structure waterborne is provided with drive device and direction-control apparatus.
According to an embodiment, hyperstatic combination that the floating structure is integrally made up of multiple indeterminate units is empty Between structure.
According to an embodiment, the floating structure in any direction on, at least 4 hyperstatic space structure lists The continuous combination of member.
For above-mentioned embodiment, it is described as follows：
A. the utility model proposes the large-scale floating structure waterborne of high safety be advantageous to reduce ripple in extreme sea condition Wave load responds, and is advantageous to play contribution and effectiveness of the material to bulk strength, makes to still ensure that it when platform principal dimensions is very big Structure has enough bulk strength redundancies.
The profile height size that the utility model limits any one floating body in lower float structure is less than applicable waters The 1/2 of maximum wave height size, therefore, the cross dimensions of single floating body are smaller.Meanwhile between each floating body in restriction float structure At a certain distance, therefore, each floating body is dispersed placement in space, and the floating body of dispersed placement is that wave gets over (around) floating body wound excessively Fluid motion and exergonic condition have been made, it is smooth to have ensured that wave flows between floating body, to reduce destruction of the billow to floating body Property load.
Illustrate (such as 0.5 times) when single floating body section principal dimensions is less than maximum wave height principal dimensions, in maximum wave height, portion Partial wave wave will extend over floating body, and part floating body will be disengaged from wave, and seaway load will be significantly increased no longer with the increase of wave height, i.e., flat There is non-linear phenomena in response of the platform seaway load to wave height, the ripple of floating structure during so as to which big wave is greatly lowered Wave load.It is readily apparent that for the floating structure waterborne of same yardstick, for Ship Structure, the utility model The seaway load that the large-scale floating structure waterborne of high safety is subject to will significantly reduce, so that its structure design is meeting equally Under conditions of specification weighing apparatus is accurate, relative to the body structure of ship, there is higher overall structure security.Reason is, when by When the external environment condition load increase of unexpected factors (wave of over writing, hurricane etc.), the utility model high safety it is large-scale floating The seaway load that formula structure is subject to almost no longer increases, or increase very little, and the seaway load that common ship is subject to will drastically Significantly increase, therefore, the large-scale floating structure of the utility model high safety possesses higher structure safety stock.
B. the utility model proposes the large-scale floating structure waterborne of high safety be hyperstatic interblock space structure, can Ensure meet with foreseeable least favorable sea situation and having the worst collision of record, hit a submerged reef, stranded, the abnormal displacement of goods Deng under emergency conditions, even if partial structurtes are damaged, peace that the still deterministic structure of overall structure is not disintegrated integrally Quan Xing.
The generally hyperstatic interblock space structure of floating structure waterborne of the present utility model.Its overall structure is by top What body structure, intermediate connection structure and lower float structure combined.
The structure of the floating structure is limited in the utility model integrally in horizontal any direction across 4 or 4 More than span, a span here refer to the distance between two adjacent floating bodies and two neighboring intermediate connection structure it Between distance.Therefore, floating structure waterborne is at least by 5 floating bodies, 25 columns and one in the continuous upper tank in space The overall structure of body structure (indeterminate unit) composition.According to the knowledge of structural mechanics, 2 lower floats, 4 columns and with Corresponding to the part (semisubmersible platform can be analogized to) of upper box body structure the indeterminate of closing can be formed Space structure unit, therefore, floating structure of the present utility model in any direction on, equal at least 4 hyperstatic spaces The continuous combination of construction unit, on the whole from the point of view of, floating structure of the present utility model is at least tied by 16 hyperstatic spaces The combining structure that structure unit combines, the unit breakage (partial structurtes failure) caused by accident such as collide, hit a submerged reef, will not Overall structure is threatened safely.Therefore, structure integrally has very big fail- safe redundancy in terms of anti-disintegration.
By floating structure waterborne structure composition analysis it can be found that its underpart float structure, intermediate connection structure and Superstructure is that quantity is more and dispersed placement, each composition component are relatively " more equal with one kind in structure stress The mode of weighing apparatus " in the foreseeable least favorable sea situation of experience and has the worst collision of record, touched come what is cooperated Under reef, stranded, the goods emergency conditions such as displacement extremely, though some even certain several hyperstatic space structure unit one A little component damages exit work, and remaining structure is still the combining structure that hyperstatic space structure unit combines, still Being capable of normal work.
The utility model can carry out reasonable analysis in design by retrieving the statistics of all kinds of sea situations and accident, in advance The extreme loads of severe sea condition and the various destructive power extreme values for there are meter record Crash characteristics are quoted, because modern casualty has record Sample is abundant enough and representational, analyzes Crash characteristics accordingly and extreme value is believable, and technology people in industry What member can accomplish.In this manner it is possible to foundation is provided for the design of platform architecture, so as to ensure this reality under extreme conditions Be not in the continuous destruction of multiple local units with new, and then ensure floating structure of the present utility model under these conditions Possesses the security performance that deterministic structure is not disintegrated integrally.
Ship and ocean platform delimit pass according to the significance level of component and the difference of stress in routine techniques The species such as key member, important component, secondary member, and each primary structure member significance level of the present utility model is generally suitable , and can support each other, the wind for failing without the dependency structure caused by " weakness " component failure and integrally collapsing successively Danger.
Be different from semisubmersible platform, the subdivision of semisubmersible platform floating body be it is limited, floating body or column occur compared with When big damaged, buoyancy module will be caused damaged and a large amount of water inlets, now, as flow of inlet water is more than the discharge ability of emergency dewatering system, The change of platform entirety floading condition will just occur, and cause a series of chain reactions such as the deterioration of the stress of structure, finally, can The catastrophic consequence for tilting, being broken or even turning over and sinking can be caused.
C. the utility model proposes high safety large-scale floating structure lower float structure waterborne each floating body yardstick Smaller and dispersed placement, there is the feature of super large Area of Water Plan form, unloaded and full-load draft varies less, the influence to stability It is small to can ignore.
The profile height size that the utility model limits any one floating body is less than the 1/2 of maximum wave height size, and bottom is floated Each floating body in body structure is spaced apart, and the displacement of volume sum of class reality core buoyancy module is more than the floating structure full load full weight Equivalent water volume, while be limited under full-load draft state, the Area of Water Plan of the floating body in lower float structure outline with The area ratio of float structure outline is not more than 70%.
For example, in the worst North Atlantic Ocean marine site of sea situation environment, there is about 30 meters of the maximum wave height of record, then single floating body Maximum profile height be less than about 15 meters, therefore, floating body yardstick is smaller.The displacement of volume for limiting class reality core buoyancy module simultaneously is more than this The equivalent water volume of floating structure full load full weight, therefore, the inevitable altitude range in floating body of hydrostatic water line of floating structure Within, so as to which floating structure integrally absorbs water very shallow, and the quiet drinking water waterline of its floating body is also smaller to floating body distance from top.
The cross dimensions of single floating body is smaller, and the volume of each floating body is just smaller, thus floating body should have certain length and Quantity, there could be certain cumulative volume, if, being exactly the flat of " bamboo raft " type by each floating body without spacing and together Box float structure, in conjunction with requirement for bearing capacity, flat float structure necessarily has the Area of Water Plan of super large, and its Area of Water Plan will Much larger than normal shipboard and marine floating type platform.Wave is carried it is emphasized that super large Area of Water Plan is typically necessarily accompanied with Lotus super large response, and the utility model by more floating body dispersed placements dexterously simultaneously realize super large Area of Water Plan and compared with Small wave load response.Here water plane area refers to that the horizontal plane at water line intersects formed section, institute with floating body The water line of finger is quiet water line.
For the ratio between total displacement and total Area of Water Plan, the utility model has very big water plane area and Water Plane Integrate cloth.If for the semisubmersible platform of small-waterplane-area, normal shipboard is big line structure, then, it is relatively conventional For ship, floating structure of the present utility model is then " super large Area of Water Plan " structure.Flat structure has that center of gravity is very low, metancenter Very high feature, GM values of the present utility model than more than normal platform and high two orders of magnitude of ship, stability problem no longer into For the key factor of overall security.In addition, also due to above-mentioned reason, the utility model heaving cycle be much smaller than highest wave When the spectral peak cycle, about 5 seconds or so, while except that can have fabulous resistance to ripple stability in billow, floading condition was to all kinds of loads Such as loading capacity significantly increases and decreases, weight position is mobile, outside push-and-pull is also all extremely insensitive for lotus change, " resists and shakes with a kind of unique Put rigidity ".
D. the utility model proposes high safety large-scale floating structure waterborne, the reliable characteristic that do not sink can be achieved.
Buoyancy module on the outside of at least part in lower float structure is used class reality core buoyancy module by the utility model selection, and it is arranged Water volume sum is more than the equivalent water volume of the floating structure full load full weight, and therefore, no matter structure is by which kind of local damage, As long as floating structure overall structure is not disintegrated, it becomes possible to which deterministic guarantee overall structure can not possibly sink.
E. the utility model proposes high safety the generally super tabular morphology of large-scale floating structure waterborne, have great Metacentric height, it can ensure meet with foreseeable least favorable sea situation and having the worst collision of record, hit a submerged reef, put It is overall not topple under shallow, the goods emergency conditions such as displacement extremely, provided the foundation condition for support personnel's life security.
The minimum distributed dimension selection of the utility model middle and lower part float structure outline in the horizontal direction is equal to or greatly 4 times of centroidal distance standing level height when floating structure zero load waterborne.
The generally super tabular morphology of floating structure waterborne, by proposing in minimum distribution yardstick and structure in horizontal direction The heart while requires lower float Area of Water Plan dispersed distribution to the multiple of the distance of hydrostatic water line, therefore, of the present utility model Floating structure possesses very big recuperability and restoring moment so that there is overall structure great metacentric height (to be advised compared with industry Big 2 to 3 orders of magnitude of model) and great righting arm, it can still realize do not topple under extreme conditions.
The lower float structure of the utility model reclaimed water floating type structure uses the less floating body dispersed placement of multiple yardsticks, Synergy, the Area of Water Plan of enough displacement of volumes and super large can be provided, there is very big Area of Water Plan the moment of inertia, its Stability radius is very big, and metancenter is very high, and initial metacentric height is very big, and under unloaded and full-loading condition, drinking water varies less, to steady The influence of property can be ignored, therefore, it may not be necessary to configure the ballast tank of Large Copacity.
The drinking water of the utility model reclaimed water floating type structure width is very bigger than B/d, has in heel low-angle very big Righting arm；Because intermediate structure and superstructure have larger reserve buoyancy, equally have in wide-angle very big Righting arm；The lever of wind pressure of other the utility model reclaimed water floating type structure is smaller relative to righting arm, roll angle Also it is smaller；Various intact stability and damage stability indexs are very big much larger than the quasi- value of weighing apparatus, limit height of C.G. value allowable.
Meanwhile floating body on the outside of at least part in lower float structure is limited in the utility model and uses class reality core floating body, Therefore, meet with foreseeable least favorable sea situation and having the worst collision of record, hit a submerged reef, stranded, the abnormal shifting of goods Under the emergency conditions such as position, still ensure that its damaged stability is approximately equal to intact stability.
Floating structure waterborne is in integrally super tabular morphology, using the center of gravity of floating structure as upper vertex, with lower float knot The hydrostatic water line outline of structure is bottom face, forms a stable Anomalistic space cone, the space cone and level The maximum angle in face is 27 degree, equivalent to defining that floating structure integrally possesses a relatively low large chassis of center of gravity.In high sea In, maximum wave steepness is 1/7, and corresponding wave inclination angle is 16 degree, and under the most unfavorable processing condition, floating structure is laterally disposed in the ripple of wave On face, still ensure that floating structure does not topple under wind heeling moment and Wave Loads.Under stranded situation, due to floating knot The yardstick limitation of structure horizontal direction requires that under the reciprocal souring of wave, structure can integrally depart from shoal, without translating into Or topple.Collision can be only formed when shoal angle is excessive, high inclination-angle will not be caused to shelve.When floating structure runs into what is relatively delayed When water-bed submerged reef or seabed (such as less than 20 degree of the angles of gradient), form floating structure and be shelved on the inclined-plane of certain slope Situation, due to the effect of stable Anomalistic space cone, it can be ensured that floating structure does not topple.
The middle connection binding structure that floating structure waterborne is limited in the utility model provides reserve buoyancy when entering water, ensures Buoyancy provides the continuity that structure is distributed upwards, unexpected high inclination-angle is occurring (certain side periphery floating body enters water in whole or in part) When righting arm still be on the occasion of.Ensure that under extreme case, floating structure waterborne remains to have sufficiently large stability Safety Redundancy, from And maintain reliable resistance to capsizing.Again with it is foregoing do not disintegrate, the damaged characteristic such as do not sink of not intaking is combined, damage stability with Intact stability is essentially identical, and therefore, human life of the utility model just for guarantee thereon provides safely a kind of novel original Most basic safety condition.
F. the utility model proposes the large-scale floating structure waterborne of high safety can have sizable general size and work Industry space, while there is high resistance to ripple stability, provide looser safety condition for function and facility General Layout Design.
The outer profile size that the utility model limits lower float structure is at least more than 140 meters in one direction, example 400 meters of floating structure overall length waterborne, about 40 meters of moldeed depth, about 15 meters of height of C.G. when unloaded, 120 meters of overall width, then its deck Area is about 48000 square metres.As a comparison, 400 meters of long freighters, the largest of about 35 meters of its molded breadth, its floor space is about For 14000 square metres.Obviously, the working space of floating structure waterborne of the present utility model is huge its function general layout It is very easy to realize in the way of horizontal direction is arranged, without the side because of narrow field in vertical direction using multi-tier arrangement Formula, the isolation design being more beneficial for for multi-tier arrangement when fire class accident occurs and the evacuation arrangement of personnel.
Meanwhile can be under the 5-6 level sea situations of routine work, wavelength length corresponding to the wave spectral peak cycle be less than about 100 meters, The rocking tendency of floating structure is mainly relevant with the ratio between wavelength and floating structure overall length, in order to keep platform to have in all directions Preferable resistance to ripple stability, particularly reduce platform can operation sea situation wave motion response, limit floating structure waterborne extremely Few yardstick in one direction is more than 140 meters, and floating structure is stable under operating environment, sea-keeping is good.
G. the utility model proposes high safety large-scale floating structure waterborne have preferable navigation performance and adjustment bow to Ability.
Floating structure waterborne is limited in the utility model and drive device and direction-control apparatus are installed and due to absorbing water very Shallow, if floating body uses elongated bar shaped, resistance is relatively small, is easily realized not less than 6 sections in maximization condition also its speed of a ship or plane. Specifically multiple all-direction propellers can be arranged with stern in the bow of each floating body of lower float structure in terms of power configuration, this There is a certain distance before and after a little propellers and can be rotated with omnidirectional, can be with huge according to needing to produce while omnidirectional's thrust is produced Deflection torque.Sail specifically can be also set on floating structure on the water, directly push away propeller and rudder etc. to realize, can there is platform Good omnidirectional's navigation performance and extremely strong bow effectively can hide typhoon to controling power by escaping in advance.Can also basis Change the needs of seaway load, effectively adjust the angle of meeting of platform and wave.In addition, even if platform runs out of steam completely, Because platform all directions principal dimensions is very big, athwart sea direction can be deflected into automatically in storm, this is that normal shipboard is most dangerous State, still, because this platform transverse stability is fabulous, the possibility do not toppled, therefore, automatic athwart sea form, it can subtract significantly on the contrary Whirlies threaten this platform structure maximum vertical bending moment load, turn into a kind of unique adaptive structural safety performance.
As shown from the above technical solution, the beneficial effect of the large-scale floating structure waterborne of high safety of the present utility model exists In：
1st, floating structure waterborne possesses multiple beneficial high safety performance, solves the basic difficulty for exploring and developing Sea World Topic.
The large-scale floating structure waterborne of high safety of the present utility model integrally use by lower float structure, superstructure and The mode of intermediate connection structure combination forms overall super flat hyperstatic interblock space structure, outer in lower float structure Side part floating body uses class reality core floating body, and the displacement of volume sum of above-mentioned class reality core floating body is more than the equivalent of the floating structure full weight Water volume, lower float structure disperses are arranged and are super large Area of Water Plan structures.Abovementioned technology organically combines, joint is made With so that the large-scale floating structure waterborne of high safety of the present utility model is small to seaway load response, motor imagination is small, it is good to possess Good sea-keeping and lifting capacity.Meanwhile the stability of floating structure waterborne is fabulous, it can significantly simplify Calculation of Stability and check, Design efforts would is reduced, it is insensitive to sea situation, operating load change, it enormously simplify to ensure structure " stability " and set Numerous and diverse loading and ballast requirement, it is not necessary to because stability problem is configured Large Copacity ballast tank and complicated ballast operation, and Large Copacity ballast tank has substantial connection with security, may when the ballast tank of Large Copacity occurs more than the damage situation of specification Cause to topple and sink.If by the closing of the empty cabin of ship into real core, during ship in ballast just can not ballast, then absorb water too shallow, nothing Method ensures stability；Similarly, lower floating body and column sky cabin are such as closed into real core by semisubmersible platform, will also be unable to ballast, Wu Fashi The transformation of existing partly latent and non-partly latent operating mode, (partially surfaced condition can not move boat, partially surfaced condition operation).Therefore, ship and half If submersible platform will realize its function, it is necessary to set ballast tank.
What the structure overall security of the large-scale floating structure waterborne of high safety of the present utility model was to determine, its structure is lost Effect pattern has essential distinction with ship and semisubmersible platform.Meet with foreseeable least favorable sea situation and have record It is worst collide, hit a submerged reef, be stranded, goods displacement etc. extremely is under emergency conditions, although structure it is possible that local damage, It is that follow-up worse situation will not be caused to occur, has fundamentally prevented floating structure and integrally produced overall fracture, disintegration.Make Obtain after accident is formed, personnel can still rely on huge safe space and the relatively great amount of resource dimension that structure provides in itself The existence of more personnel is held, is waited for rescue, the personnel for escaping to be likely to occur during lifesaving and after abandoning ship is largely avoided and is missing It is dangerous with human life caused by the limited time that sustains life, so as to ensure that the life security of personnel thereon provides most The reliable guarantee condition in basis.
Spot ship and ocean platform resistance to capsizing and unsinkability are all limited, the external work for causing to topple and sinking With and human operational error be all random, can only be handled with the method for probability.And the utility model is using super flat Hyperstatic interblock space structure, class reality core floating body, dispersed placement and provide the intermediate connection structure of safe restoring force, super large The technological means such as the lower float structure of Area of Water Plan form are mutually combined, and are realized and " are met with foreseeable least favorable sea Condition and there is the worst collision of record, hit a submerged reef, be stranded, antidumping of the goods displacement etc. extremely under emergency conditions, anti-sinking Could not power." realize antidumping, anti-heavy change of the ability by " probability " to " certainty ", for ship with ocean platform most Basic safety standard particularly human life's safety standard, can be that reference is adjusted on a large scale with the related specification in land Whole, simplified and release, revolutionary change can be produced to mankind's Activities of Ocean.
2nd, the sensitiveness that the security of floating structure waterborne influences on human factor is reduced, greatly simplifies answering for management system Miscellaneous degree and operating cost.
The large-scale floating structure structure waterborne of high safety has high security in itself in the utility model, no matter which kind of corresponds to Using function, even if the operational error of human factor occurs, also it is unlikely to cause the catastrophic effect to cause casualties.Cause This, can substantially reduce influence of the operational error to the overall safety of floating structure waterborne, effectively simplify floating structure waterborne Management system and operation program.By improving the floating structure waterborne security of itself, bring be the market access, using, The great convenience of each side such as management and operation.
3rd, the versatility of floating structure waterborne is greatly improved so that floating structure design depends on big using the degree of function It is big to reduce.
The superstructure of the utility model reclaimed water floating type structure can use space frame structure and casing (conventional plate Shell) realization of structure two ways.The use of space frame structure causes superstructure design to have more flexibility.
Frame structure refers to be connected with each other in a manner of rigid connection by beam and column, forms the structure of bearing system, i.e., by beam and column The space frame of composition resists the various load occurred during use jointly.
It should be appreciated that the post and beam structure of the superstructure can be reach safety classes of structure requirement any Post and beam structure type.For example, multiple vertical or transverse truss formula supporting constructions can be utilized, composition forms top knot Structure, while it is separated out numerous functional cabins.
When the frame structure mode formed using spatial beam-column is to realize superstructure, the structure design of superstructure is certainly By spending (or flexibility) relative to traditional ship with that will be greatly increased for water floating body structure design, top functional cabin is set Meter arrangement can flexibly change.Superstructure is transformed leeway and will greatly increased, and main load-carrying construction is beam, post and other Support (being possible to not have), remaining component (upper lower roof plate of partition member, Working cabin between deck, Working cabin etc.) can be set Non-principal load-carrying construction is calculated as, local function load is subjected only to and is not involved in floating structure overall structure stress waterborne.Due to Above-mentioned characteristic, the non-principal load-carrying construction of floating structure waterborne can arbitrarily be changed on the premise of local function load is met Without influenceing overall structure stress；Non-principal load-carrying construction is it is also contemplated that use nonmetallic materials so that anticorrosion is greatly lowered Cost；Non-principal load-carrying construction by the way of (non-solder) is assembled it is also contemplated that be connected on main load-carrying construction.
4th, the safety in utilization and convenience of floating structure waterborne are greatly improved.
The utility model reclaimed water floating type structure bottom float structure uses the small yardstick floating body of dispersed placement, therefore has super Big Area of Water Plan and initial stability (GM) value of super large, it is empty, full-load draft change is small, without configuring Large Copacity ballast tank, need not Check conventional intact stability and least favorable environmental factor it is folded when stability, including whole loading masses 50% region in any direction Interior concentration unbalance loading.It is fabulous and right that the utility model reclaimed water floating type structure possesses high security and " stability ", " sea-keeping " All kinds of load changes are insensitive, have unique rigidity is anti-to wave ability.Therefore floating structure can be greatly improved relative to not With the versatility for using function, ship critical constraints system of the prior art and the feature using function are different from.For example, it can permit Perhaps large ship is without masking marine site and the direct berthing of the utility model platform.
The utility model reclaimed water floating type structure overall structure is the space structure of middle part hollow out, and supernatant centre connects Binding conformational space dutycycle very little, the difference of deck top and the bottom air flow field is little, can reduce floating structure deck overdraught The mutation in flow field, relative to conventional box floating body (ship), safer stable air stream can be provided for all kinds of airborne vehicle landings Field condition.
There is the utility model reclaimed water floating type structure the upper table space of planes of overlarge area and the top of ultra-large volume to make Industry cabin, meanwhile, have between superstructure and lower float ultra-large volume using space, have overlarge area in approximately level Operating area, therefore, the operating function such as can easily realize very much all kinds of carryings, hang.Its general function arrangement can be with Based on horizontal layout, there is the application scenario of densely populated place on floating structure on the water, arrangement is vertically arranged relative to more floors Based on for, be more beneficial for the isolation design of fire class accident and the evacuation arrangement of personnel.
The class reality core floating body of the utility model reclaimed water floating type structure can use filling removably so that structure is repaiied Multiple and periodic inspection is simple and easy.
In a word, the large-scale floating structure waterborne of high safety of the present utility model is mainly characterized by：High stability, high safety Property, meet with foreseeable least favorable sea situation and having the worst collision of record, hit a submerged reef, stranded, the abnormal displacement of goods Deng under emergency conditions, the effect not waving significantly, do not disintegrate, not toppling, not sinking can be reached；Great versatility, overall knot For structure to relatively low using the degree of dependence of function, superstructure can greatly improve design flexibility using space frame form；It is good Good workability, more loose are required to operating personnel's overall qualities and the operation management of structure entirety；Meanwhile yardstick it is big, Shallow draft, sea-keeping are good, and possess big working area and big working space.

Embodiment
Embodying the exemplary embodiments of the utility model features and advantages will describe in detail in the following description.It should be understood that It is that the utility model can have various changes in different embodiments, it does not all depart from the scope of the utility model, and Explanation and diagram therein are treated as purposes of discussion in itself, and are not used to limit the utility model.
The utility model embodiment proposes a kind of large-scale floating structure waterborne for being avoided that the high safety to turn over and sink.Specifically, The utility model embodiment provides a kind of large-scale floating structure waterborne of high safety, and the structure can be floating type comprehensive coverage base Ground, it is available for various ships directly to moor and leans on, deck plane can be equipped with large-scale loading mechanization, there is provided handling, transhipment and store function.Its base This kenel may be selected to be super flat space structure, mainly include lower float structure, superstructure and intermediate connection structure.From Security standpoint sets out, and this is the brand-new floating structure type for being different from all ships and ocean platform.
Fig. 1 is the forward sight cross-sectional view of the large-scale floating structure waterborne of high safety in the utility model embodiment； Fig. 2 is the side structure schematic view of the large-scale floating structure waterborne of high safety in the utility model embodiment；Fig. 3 is that this practicality is new The top view cross section structural representation of the large-scale floating structure waterborne of high safety in type embodiment.Referring to figs. 1 to shown in Fig. 3, this reality Floated with the large-scale floating structure waterborne of the large-scale high safety of new embodiment including superstructure 1, intermediate connection structure 2 and bottom Body structure 3.The large-scale floating structure waterborne of high safety length (L) in the horizontal direction or width (B), can reach and are equal to Or more than high safety large-scale floating structure zero load waterborne when centroidal distance standing level height 4 times of (H), be integrally a kind of super flat Flat-shaped profile.
For example, floating structure waterborne is at least by 5 floating bodies, 25 columns and one on the continuous top in space The overall structure of body structure composition.Reference picture 13 is to shown in Figure 15, according to the knowledge of structural mechanics, 2 lower floats, 4 The part of column and corresponding upper box body structure (can analogize to a semisubmersible platform) can form an envelope The hyperstatic space structure unit closed, therefore, floating structure of the present utility model in any direction on, at least 4 are super The continuous combination of the space structure unit of static determinacy, on the whole from the point of view of, floating structure of the present utility model be at least it is super quiet by 16 The combining structure that fixed space structure unit combines, therefore structure integrally has very big redundancy in terms of anti-disintegration.
By the structure composition analysis of floating structure waterborne it can be found that its underpart float structure, intermediate connection structure are with equal It is that quantity is more and dispersed placement, each composition component in structure stress, are come in a manner of one kind relatively " equilibrium " Cooperate, meet with foreseeable least favorable sea situation and having the worst collision of record, hit a submerged reef, stranded, goods Under the emergency conditions such as abnormal displacement, even if some component damages of some even certain several hyperstatic space structure unit move back Go out work, remaining structure is still the combining structure that hyperstatic space structure unit combines, and remains able to normal work.
The utility model can carry out reasonable analysis in design by retrieving the statistics of all kinds of sea situations and accident, in advance The extreme loads of severe sea condition and the various destructive power extreme values for there are meter record Crash characteristics are quoted, because modern casualty has record Sample is abundant enough and representational, analyzes Crash characteristics accordingly and extreme value is believable, and technology people in industry What member can accomplish.In this manner it is possible to foundation is provided for the design of platform architecture, so as to ensure this reality under extreme conditions Be not in the continuous destruction of multiple local units with new floating structure, and then ensure that floating structure of the present utility model exists Possesses the security performance that deterministic structure is not disintegrated integrally under above-mentioned condition.
Ship and ocean platform delimit pass according to the significance level of component and the difference of stress in routine techniques The species such as key member, important component, secondary member, and each primary structure member significance level of the present utility model is generally suitable , and can support each other, the wind for failing without the dependency structure caused by " weakness " component failure and integrally collapsing successively Danger.
Semisubmersible platform is different from, any one floating body or column of semisubmersible platform are damaged, will caused Buoyancy module, which is intake and integrally-built stress occurs, to be deteriorated, and such as disposal would potentially result in the calamity for tilting, being broken or even turning over and sinking not in time The consequence of difficulty.
Referring to figs. 1 to shown in Fig. 2, the upper and lower surface of superstructure 1 is upper lower decks, can also increase middle first Plate.Upper lower decks participates in overall structure stress.Can be the rigidity knot that frame structure is realized in one embodiment of superstructure 1 Structure, numerous cabins have been could be alternatively formed in superstructure 1.
Frame structure, which refers to be connected by beam and column, to be formed, and is formed the structure of bearing system, i.e., is formed framework by beam and column The horizontal load and vertical load occurred during common resistance use.
Referring to figs. 1 to shown in Fig. 2, in the exemplary embodiment, in the height direction, list is may be designed as in superstructure 1 Layer distribution or at least two layers of Multi-layers distributing.And numerous cabins can be arranged in each layering, ship cabin arrangement mode can be according to function Demand is arranged.Wherein each cabin primary structural support can be at least three vertical columns, and the company that top is horizontal Beam is connect, tie-beam can be respectively in top or bottom connection column.It is attached between crossbeam and column using connector, such as Dichotomous casing joint.Can be between each part be welded to connect, riveting, bolt connection or quick clamping.In this way, by horizontal stroke Beam and column form main rock-steady structure supporter.Certainly, rod-type diagonal brace or truss can also be increased between crossbeam and column Formula supporting construction, so that the overall structure of superstructure 1 reaches the requirement of safety classes of structure.
Further, by crossbeam and column or other flow resistance of rod-support structure composition rigidity supporting structures in superstructure, such as With reference to the room constituted mode of building, close to form each functional cabin using sheet material., can because wallboard is non-load-carrying construction With from light weight board, for example, aluminum honeycomb panel, composite rock wool slab, lightgage steel joist assembled wall etc..But preferably there is resistance in selection The sheet material of fuel efficiency fruit.Top plate and floor can be selected steel plate or it is other can bearing plate.
It should be appreciated that the post and beam structure of superstructure 1 can be reach safety classes of structure requirement any Post and beam structure type.For example, multiple vertical or transverse truss formula supporting constructions can be utilized, composition forms superstructure 1, while it is separated out numerous functional cabins.
When the frame structure mode formed using spatial beam-column is to realize superstructure, the structure design of superstructure 1 The free degree (or flexibility) relative to traditional ship with that will be greatly increased for water floating body structure design, top functional cabin Design arrangement can flexibly change.Superstructure 1 is transformed leeway and will greatly increased, main load-carrying construction be beam, post and its It supports (being possible to not have), and remaining component (upper lower roof plate of partition member, Working cabin between Working cabin etc.) can be set Non-principal load-carrying construction is calculated as, local function load is subjected only to and is not involved in floating structure overall structure stress waterborne.Due to Above-mentioned characteristic, the non-principal load-carrying construction of floating structure waterborne can arbitrarily be changed on the premise of local function load is met Without influenceing overall structure stress；Non-principal load-carrying construction is it is also contemplated that use nonmetallic materials so that anticorrosion is greatly lowered Cost；Non-principal load-carrying construction by the way of (non-solder) is assembled it is also contemplated that be connected on main load-carrying construction.
And may also provide in another embodiment for superstructure 1, can be the rigid structural layer of body structure composition, mainly Load-carrying construction is space slab and girder, and the component such as transverse bulkhead, longitudinal girder in cabin, the upper lower decks for forming cabin is generally The calculating of longitudinal strength is participated in as force structure component.
Body structure referred herein, the space case structure that the plate mutually constrained with polylith forms, each block of plate are held By local load, distributed moment undetermined is born on four sides.
For example, superstructure 1 can be tied by the space-bin that deck, leg and some vertical and horizontal bulkheads form Structure.Its deck can have several layers of, such as main deck, between deck, lower decks.The main body of superstructure 1 can be designed as having storage Standby buoyancy, the i.e. main body of superstructure 1 are watertight or have certain watertightness.The main body of superstructure 1 can be an entirety The assembly of body structure or several box structures in length and breadth, such as sphere of movements for the elephants shape, " well " font, " △ " font.
For example, the structure of superstructure 1 may be selected using mixed matrix form in length and breadth, in each region, the main direction to beam is not Together, horizontal cloth is all used both perpendicular to the main strong frame that distance is set into beam length direction and is not waited, all major lateral skeletons Put, all inwalls use vertical stiffener.Because frame structure is spot ship or the conventional knot in offshore floating type structure cabin Configuration formula, therefore, it will not be repeated here.
It should be appreciated that the superstructure 1 also may be selected by body structure and two kinds of matched combineds of tower structure Form.For example vertical or horizontal plate-girder is added in tower structure, further to improve structural strength.Can certainly be in case In structure based on body structure, add various columns and crossbeam and strengthened.The middle part of superstructure 1 uses frame-type knot for another example Structure, and periphery and or bottom use body structure.
On the overall maximum wave height using waters of superstructure 1 of the utility model embodiment, and in superstructure 1 The multiple cabins formed are chosen as salable cabin, if under the cabin structure situation of Multilayer partition, the cabin at least below middle part Room is sealing under normal circumstances, can refer to current cabin structure.So, if running into extreme case, the more floating bodies 3 in bottom lose During effect, superstructure 1 remains to keep from floating.
Referring to figs. 1 to shown in Fig. 2, in an embodiment of intermediate connection structure 2, include the attachment structure of first direction 21, first direction intersects with horizontal plane, and the attachment structure 21 of first direction includes multiple spaced floating bodies, can be regarded as The upward extension of more floating bodies, this part of floating body belong to specific function floating body, under extreme conditions, when floating structure integrally occurs During extreme wide-angle tilt, multiple spaced floating bodies that the attachment structure 21 of first direction includes are immersed in the water, it is possible to provide Buoyancy, it is overall to produce larger restoring moment because righting arm is very long, it is more reliable can make it that floating structure integrally possesses Stability.
It should be noted that when larger inclination occurs for floating structure, the intermediate connection structure intersected with horizontal plane enters water, energy Safe restoring force is enough provided.For example, according to current design calculating and experimental data, when the centre intersected with horizontal plane connects The cross-sectional area sum of binding structure, more than 5% of Area of Water Plan at the more hydrostatic drinking water of floating body 3 in bottom, also, outermost and water When the intersecting intermediate connection structure of plane to the distance of floating structure center of gravity is more than twice of floating structure distance of centre of gravity water surface distance, The total restoring moment of floating structure can be more than the maximum that floating structure is subject under the synergy such as the wind being likely to occur, wave and topple Torque, it can make floating structure that there is the security do not toppled.
For example, the floating structure of the utility model embodiment is also an option that the connection knot for setting multiple second directions Structure 22, plane extends the attachment structure 22 of second direction downstream.
For example, the floating structure of the utility model embodiment can select only to set the attachment structure of first direction 21, the accessible water surface working space in big region can be formed between floating body.
Intermediate connection structure 2 in the utility model embodiment, multiple floating bodies of the attachment structure 21 of its first direction can be with It is the multiple float type attachment structures for intersecting at the water surface, the width in these float type attachment structures section in the horizontal plane is less than phase The waterline breadth of floating drum 31 even, described " width " refers to the size on the length direction of floating drum 31 of strip.First Multiple floating bodies of the attachment structure 21 in direction can be the hollow attachment structure extended above and below high column structure, or flat chip； Simply in the utility model embodiment, multiple floating bodies of the attachment structure 21 of first direction are spaced, for wave Pass through, the external load that platform is integrally born is reduced, to ensure safety.Alleged multiple float type attachment structures should manage in this section Solution, refer to that corresponding single floating drum 31 is connected with more than five spaced float type attachment structures.
