Technical field
The present invention relates to anti-platform SPBM field, the particularly configuration of the anti-table flotation cartridge type wind one-point mooring system of super large marine.
Background technology
The national army standard " windproof mooring drum " of promulgation in 1991 (GJB1119.91) has been made regulation to the design and use of the anti-platform mooring system of military single-point floating drum, but because theoretical shortcoming and poor for applicability, particularly fail to be promoted the use of always, cause China to be in unconformable situation always at the configuration of the anti-table flotation cartridge type wind one-point mooring system of large-scale and super large marine at the reason poor for applicability of super large marine.
" windproof mooring drum " (GJB1119.91) acts on is to guarantee the windproof mooring safety of super large marine.At present, the up-to-date windproof mooring drum national standard GJB1119A-2006 of China revises on the basis of GBJ1119-91, but still lack pontoon type single point mooring (SPM) at the super large marine standard of combating typhoon, the windproof one-point mooring system construction that causes the coastland to be combated typhoon still is in a kind of relatively state of difficulty, and there is potential safety hazard in quite a few facility.The problem that primary standard exposes is more and more serious, and the problem that has many theories and use mainly shows:
(1) research of existing anti-table flotation cartridge type single buoy mooring system is limited to little medium-sized boats and ships or the naval's super large marine to non-extreme sea condition more, does not see the research to the anti-platform mooring system of the single-point floating drum of large-scale especially super large marine under the typhoon situation that with the high wind speed is principal character.
(2) along with the maximization and the ship building industry development of China's boats and ships, primary standard can not satisfy operating needs.The super large marine mooring force expression formula that primary standard provides is not comprehensive, and mooring force is directly proportional with the captain and the beam, and the super large marine wind-engaging relevant with moldeed depth, is subjected to flow area etc. to there is no direct relation.
(3) to the response shortage scientific understanding of the boats and ships characteristics of motion, stress characteristic and different hydrometeorological condition under the typhoon effect to system.
(4) stochastic and dynamic of the anchor chain pulling force that causes owing to the combined influence that is subjected to enchancement factors such as marine site wind load, wave force, flow force changes, especially the maximum transient state pulling force that under stormy waves sudden change and hazard weather, causes, above-mentioned stressed model complexity, model parameter need and be revised by the measured data check, under the measured data situation that lacks under the typhoon effect, be difficult to set up single point mooring (SPM) and two point mooring math modeling accurate, science.
(5) not shipmate type is different to buoy mooring's system requirements, and there is certain difference in model, and existing model does not have at specific type of ship, and specific aim is poor, brings inconvenience to practice.The present invention is primarily aimed at super many types of boats and ships, is representative with 300,000 tons of oil carriers, and specific aim star strengthens, the also corresponding increasing of the practicality of model.
In windproof single buoy mooring system, the mooring force that boats and ships produce under the effect of stormy waves stream is one of sixty-four dollar question in the practical application, how to determine reasonably that mooring force is the key issue of research.Calculate about single point mooring's power, Europe, the United States, day etc., all there was separately industry mark type in state, these standards and treatise all are to be applicable elements with certain water environment, Consideration differs, computing formula is totally different, result of calculation is also inconsistent, is difficult to direct application, needs to carry out necessary checking or correction by physical model.
To sum up, in view of the study limitation of present most of relevant single buoy mooring systems in the alongside loading and unloading operation, shorter mention is to the single point mooring (SPM) of windproof state, and the achievement in research of existing windproof single buoy mooring system can not satisfy operating needs, especially for few very few of the research data of the windproof single point mooring (SPM) of super large marine.Therefore, be necessary windproof single buoy mooring system to be carried out systematic study fully using for reference on the basis of existing correlative study achievement.

Square being directly proportional of the long-pending or fluid action face of fluoran stream surface and Ship's Principal Dimensions, under the identical conditions, wind, stream are made a concerted effort can the increase rapidly along with the increase of Ship's Principal Dimensions.
(1) floating drum---float buoyancy
Size that floating drum is different and model have different buoyancy, and for the boats and ships of the different tonnages of mooring, this moment, floating drum was in the natural balanced state when not working, and buoyancy equals gravity.
(2) structure of anchor chain and gravity
Anchor chain is divided into two kinds of stud chain and studless cables by the chain link structure.Size, when material is identical, the intensity ratio studless cable of stud chain big be out of shape for a short time, and is difficult for distortion when stacking, so extensively employing on the seagoing vessel.Studless cable generally only is used for canoe.
(3) catenary equation finds the solution
Anchor chain mainly bears tension force T (bending stiffness generally can be ignored), so the general type of catenary equation is:
In the formula: S---the length of chain cable between F point and E point, m;
T---the suffered pulling force of anchor chain, N;
W---the weight of unit length anchor chain, kg/m;

3) comprehensive effect
(1) wind, wave, stream reach the Force Calculation of single-point mooring steamer under the mutual action separately
The final balance position of boats and ships is a condition with distinguished and admirable balance of making a concerted effort with the anchor chain Horizontal Tension under the distinguished and admirable synergy.Therefore, the extended line of distinguished and admirable active line of making a concerted effort will be by hawse hole, and the reversing sense of force action line is the direction of anchor chain.The direction of anchor chain usually and bow to inconsistent.
(2) relationship analysis of motion of ship and mooring anchor chain
Under the static balance state, motion of ship is to the reversing sense decision by wind, stream force action line.Under dynamicmodel, motion of ship is by the position in current ship anchor chains hole and the determining positions of floating drum.
(3) motion of ship and mooring anchor chain are to the influence of floating drum motion
When horizontal mooring force during greater than the ground cable Horizontal Tension, floating drum is (away from the direction of anchorage) motion laterally; When horizontal mooring force during less than the ground cable Horizontal Tension, floating drum is (near the direction of anchorage) motion to the inside.
(4) measured value and math modeling comparison (referring to Fig. 3)
The strain gage electrical measuring method is adopted in the test of anchor chain mooring force.The temperature self-compensation method is adopted in test, at first is converted to electric quantity signal by the bar structure strain of strain unit, amplifies the change-over circuit output voltage signal by half bridge measurement circuit, four tunnel strain adapters and signal again.This anchor chain mooring force test is mainly carried out the test and the analysis of dynamic tension to the anchor chain between floating drum and the anchorage piece.The maximum peak valley stress/pulling force of quantitative analysis measured point dynamic stress/pulling force is as maximum tension stress/pulling force (being peak value, with "+" expression) or maximum crushing stress/pulling force (being valley, with "-" expression).
The calculating anchor chain that measuring point goes out is stressed.The stressing conditions that calculated with mathematical model is gone out and the data of actual measurement compare again.Normal when stressed at anchor chain, the actual loading of anchor chain and boats and ships are subjected to the distinguished and admirable figure of making a concerted effort identical substantially.
(5) the stressed and stressed conversion of anchor chain of hull
To make every effort to tension force on the anchor chain according to horizontal mooring, at first must determine the vertical angle Φ 2 of anchor chain water exit and anchor chain vertical angle Φ 3 at the hawse hole place.
(6) the floating drum mooring force computation optimization of unpowered boats and ships
When the big stream of wind hour, boats and ships should increase ballast, reduce area exposed to the wind; When the wind rill is big, should reduce ballast, be subjected to flow area thereby reduce.
(7) be suitable for the ship type analysis
Because the representative ship type of 30 ton boats and ships is oil carrier and bulge carrier, both overall difference are less, can both be suitable for.
Beneficial effect

When flow velocity was too big, boats and ships are suffered made a concerted effort to obey flow velocity, is subjected to flow area big, and boats and ships are suffered distinguished and admirablely makes a concerted effort greatly more, and promptly the ballast for cruising amount receives greatly distinguished and admirable big more more.
1) for regular situation.When the suffered flow velocity of boats and ships was 0.8m/s, wind speed was during less than 35m/s, and stressed distinguished and admirable with joint efforts little during than ballast 1/4 during clean ship, ballast 1/4 boats and ships are stressed stressed littler than ballast 1/2.
2) when wind speed during greater than 35m/s, ballast for cruising 1/4 be subjected to distinguished and admirable make a concerted effort minimum.So, in typhoon season,, advise 1/4 ballast if be that the territory flow velocity of swimming is little, still, it is suffered distinguished and admirable all from positive stem that this is assumed to boats and ships, and related management personnel still should look concrete distinguished and admirable situation level pressure carries situation.
According to thing mould ship type data, and 4 of Zhoushan systems of buoy mooring are provided with the limiting condition stormy waves flow data that meet position 100 years, calculate boats and ships 1/5,1/4, and the distinguished and admirable wave under 1/3, the 1/2 ballast situation is made a concerted effort;
According to above force diagram, cross the limiting condition analysis at two places for Mount Dai, Buddhist; Because unrestrained application force is close opposite substantially with the wind action force direction with the force direction of stream, increases stressed urgency with ballast for cruising and increase so two places are crossed in Mount Dai, Buddhist.Limiting condition analysis for Ma Zhi, five brave reefs, two places, because wind, that unrestrained force direction is close is opposite substantially with the force direction that flows, so crossing two places, Mount Dai, Buddhist increase stressed reducing with ballast for cruising, further specify not shipmate type, under the operating mode of different distinguished and admirable waves, different ballast situations to boats and ships stressed influence difference, operating personal more should take into full account the actual conditions of mooring steamer and actual stormy waves stream situation at that time, decision ballast situation.Therefrom about 1/4 ballast is all more moderate to various stormy waves stream situations as can be seen.
