Description

Mooring system

Technical field

The present invention relates to a kind of system that is used for mooring and regains float facility and structure waterborne.

Background technology

The known mooring system that is used for floating struction comprises and is connected in facility or structural anchor, counterweight and attached tether in a large number.Anchor can take a different form, but all is used to its attached tether is remained on the water body bottom that described structure floats.For equilibrium activity power (such as wind, wave or trend) and the described structure of maintenance position on the water structurally, can on anchor line, increase some extra counterweights.According to the situation that described structure expection suffers, can also be in conjunction with some extra mooring and restriction rope.

A problem of this known mooring system is, when described structure must be regained from water, has some problems.Because a large amount of mooring and restriction ropes is attached on the described structure, so must before described structure can shift out from water all tethers be untied.This work needs people's participation usually, and in order before regaining described structure each root rope to be taken apart, operating personal must be climbed on the described structure.Under deep-sea or inclement weather, can't do like this in view of security reason sometimes.Therefore, the withdrawal of described structure will postpone, and can postpone some days in some cases quickly.This delay can cause serious time and cost issues, and maintenance or erection schedule can be owing to this delay is affected simultaneously.

The another one shortcoming of known system is that they are generally used for only structure of mooring of each system.In same place a large amount of structures is installed if desired, each system all needs independently anchor point, counterweight and tether so.Therefore, twine described structure certain distance that must be spaced from each other for fear of different tethers.Make described structure space meeting cause the space efficiently to utilize by this way.In view of economical, attractive in appearance or environment reason, desirable usually is that a large amount of structures is placed in the as far as possible little space waterborne.

The another one shortcoming of known system is, can't efficiently utilize the available depth of water.For the reply billow and the rapid required amplitude of oscillation of trend can require to have bigger range of movement before the tensioning of mooring rope.If the tensioning of mooring rope, load can raise extremely apace so---be commonly referred to as " rope is seized phenomenon (line snatching) ".If described structure is moored in shallow water and billow and/or the powerful trend, it is very serious that this problem can become.Also have, known system can't efficiently utilize the suspention counterweight on mooring rope or the assembly.The suspention counterweight is very expensive, and self might be on described structure applied load, this load might huge or not wish to exist.

The another one shortcoming is, known mooring system can't be with described features simple structure, be connected on one or more facility supply source (utility supplies), such as electric power, fluid or water safely.In general, this connection must be finished on the water surface or near the water surface, and is irrelevant with being connected of mooring rope.

In addition, many known mooring systems all are confined to them and all are used to tackle load (such as the marine structure that only is used to tackle from the wave of a direction) from a direction.If they are come from the power of non-expectation direction, this system can become built on the sand.This power can cause described structure to rotate or oscillating motion, can cause like this assembly in described structure and the mooring system is caused damage.

The specific embodiment

In Fig. 1 (a) and 1 (b), first embodiment that is used for the mooring system of floating struction waterborne according to of the present invention has been shown.This mooring system is used for need together using at structure, maritime affairs boats and ships or the facility that water is fixed in ad-hoc location with any.But in illustrated embodiment, this mooring system is used for fixing a wave energy converter (WEC), and this wave energy converter itself is the theme of the International Patent Application PCT/GB99/03204 of same Applicant.Therefore will no longer carry out more descriptions here to this WEC.

As shown in Fig. 1 (a), WEC 1 floats on the water surface, and at its front end 3, and---that is to say the end facing to expection wave action or trend---has a pivot harness or yoke 2.Below yoke 2, be fixed with a connection cord or counterweight tether 11, be fixed with a main counterweight or tether counterweight 10 on it.First or front side anchor line 16 be attached on the tether counterweight 10, and have first or front side anchor 15 of known type away from place, the end of tether counterweight 10 at front side anchor line 16.Though, having three front side anchors 15 and three front side anchor lines 16 at the embodiment shown in Fig. 1 (a) and 1 (b), this system only need use a front side anchor and a front side anchor line.According to the work requirements of system, can increase some extra front side anchor and front side anchor lines.Auxiliary counterweight or counterweight group (clumpweights) also can optionally be set on front side anchor line 16, be used for the friction force that provides extra as required.

Also be connected with one second or rear side anchor line 13 and second attached or rear side anchor 18 on yoke 2, they also are known type.Between WEC 1 and rear side anchor line 13, also be connected with one and support or wave rope 14, be used for helping firm WEC 1, as the back will as described in.Also have, need should be appreciated that, described rear side anchor is the optional assembly with waving to restrict, and they can use under certain applications.Fig. 1 (b) shows WEC 1, front side anchor line 16 and rear side anchor line 13 schematic plan view when the wave action that is subjected to coming from direction shown in the arrow 4.

An advantage of mooring system is that it is specially adapted to be in array fixedly boat structure shown in Fig. 1 (a) and 1 (b).As shown in Figure 2, a large amount of WEC or other structure can utilize the shared anchorage point on the sea bed to be kept, and can sharedly be electrically connected or the like.Under need be with the occasion of one group of WEC 1 mooring in same place, they can be arranged in a row, as shown in Figure 2.Each WEC 1 all has basically and reference Fig. 1 (a) and the identical mooring system of the described mooring system of 1 (b).But the difference of the mooring system in the array is that front side anchor 15 is shared by adjacent WEC 1.Therefore, the 16 shared same front side anchors 15 of the front side anchor line on the adjacent WEC 1.Under the occasion that has a more than row WEC/ structure, the front side anchor 15 among each row is also as the rear side anchor among the adjacent row.As shown in Figure 2, the rear side anchor line 13 on the WEC 1 is connected between the front side anchor 15 on the WEC among tether 11 on the WEC 1 and next row.Except shared anchor, adjacent WEC also can be via one or more umbilical facility supply line 27 shared multiple facilities, and in illustrated embodiment, described supply line 27 is a cable.As further explaining in the back, umbilical pipeline 27 is suitable for making them around described array service continuously, even certain WEC is owing to some reasons are taken out temporarily.Also have, because described umbilical pipeline is connected (but be they are positioned at the water surface following be not to arrive water bottom) by " median water level ", so only need the main supply cable 80 of described array to be positioned at water bottom.So just avoided also having the rope in described mooring system multiple cable or the umbilical pipeline that is positioned at water bottom.

In specific embodiment shown in Figure 2,, in each WEC 1, be provided with electric switchgear for as circuit breaker.Thus, if fault has appearred in certain the root cable 27 that is connected between two WEC 1 in the described array, the circuit breaker among the relevant WEC will trip, so that isolate this root failure cable.Thus, described array can work on when changing described failure cable.

Fig. 3 (a) and 3 (b) show the yoke 2 in the mooring system in more detail.Yoke 2 is designed to bigger angular range 5 of (when watching) pivot in a vertical basically plane with respect to WEC 1 in Fig. 3 (a) and 3 (b), angular range 5 is contained the above and below of the water surface 9.So just allow that yoke 2 is pivoted around the front end 3 of WEC 1, thereby make the lower end of yoke 2 even to be recycled to the water surface 9 under the condition of device need not to remove any time.Yoke 2 also is suitable for pivoted, moves in its moorings under the condition that yoke 2 and WEC 1 do not come in contact so that allow WEC 1.

Below with reference to Fig. 3 (b), can see that yoke 2 comprises a pair of arm spare 7, this is connected together to the lower end of arm spare 7 at them.First or upper end of arm spare 7 also are connected on the respective end of a quill shaft spare 8, so that make yoke 2 triangular in shape basically.Yoke 2 can also have one or more horizontal brace 6, allows that like this yoke 2 disperses mooring load.Horizontal brace 6 is allowing that still yoke 2 carries out reinforcement to yoke 2 around the front end 3 of WEC 1 in pivoted.

Fig. 4 (a) and 4 (b) illustrate described mooring system and how provide recuperability to WEC 1 when standing wave action.As previously mentioned, the lower end of yoke 2 is connected on the tether counterweight 10 by tether 11.Rear side anchor line 13 and rear side anchor 18 are connected on the described tether, although also can be connected by any other appropriate action, preferably utilize connecting panel 12.Tether counterweight 10 utilizes front side anchor line 16 to be connected on the front side anchor 15.When static, described system is configured such that tether counterweight 10 leaves sea bed 17 suspention just.Rear side anchor line 13 is connected on the rear side anchor 18 in the rear end of WEC 1, and provides the mooring system of recuperability must make WEC 1 and system move forward.

The displacement backward how described system that shows Fig. 4 (a) takes place under the wave action that comes from direction shown in the arrow 4 at WEC 1 produces a restoring force R HIn displacement process backward, yoke 2 and tether 11 are an angle φ with respect to vertical direction, because the effect of tether counterweight 10 produces a restoring force R who returns back to dead position HFor until angle φ (near half of the depth of water) near 30 degree, the property retention linearity of described system, but after this, for less than the angles of about 60 degree (near the depth of water 85%), restoring force R HBecome no longer linear, still " seize " phenomenon and avoided with displacement.As those skilled in the art will be appreciated that, " seizing " phenomenon can take place when lax mooring rope stands substantial load suddenly.An example of " seizing " phenomenon is being positioned on the sea bed and lax tether takes place when standing substantial load owing to described structure is moved when the tether counterweight.Along with rope is tensioned, described tether counterweight will be raised up from sea bed, and inertia and raised up the sediment from sea bed along with described counterweight and may act on suction on this counterweight also can increase the load on the described tether.This load that applies suddenly on rope is known as seizes load.

Fig. 4 (b) shows described system and how to produce a restoring force R at the displacement forward towards wave direction 4 HRear side anchor 18 and rear side anchor line 13 act on the bottom of yoke 2, to produce an oblique angle on described yoke 2.So just form a restoring force R as shown in the figure H

As shown in Fig. 5 (a) and 5 (b), described mooring system allows that WEC 1 swings around vertical pivot in response to the change of incident wave direction.Obtainable range of movement is by being limited with the rear side anchor line 13 coefficient ropes 14 that wave.The length of these ropes 13,14 can be selected to and limits oscillating motion as required.For the coasting area, the anticipated orientation 4 of waving limit and generally will be with respect to the incident wave is+/-90 degree.Fig. 5 (a) shows at the general extreme angles that comes from by the wave of starboard direction shown in the arrow 19.Fig. 5 (b) shows at the general extreme angles that comes from by the wave of larboard direction shown in the arrow 20.The bigger if desired angle of waving, so described mooring system can have a swivel joint, fully rotate so that allow it, and electric power/other interconnects and will realize by slip ring or allied equipment.

The another one function of described mooring system is to provide bigger rotational stabilization around a Gent dead axle line.At illustrated WEC, described mooring system is used to the roll stability that provides extra.Yoke 2, tether 11 and tether counterweight 10 make WEC have extra roll stability around its longitudinal axis jointly, as shown in Figure 6.Utilization is connected in the tether counterweight 10 on its lower end, and yoke 2 moves in the mode identical with keel on the yacht, produces the rolling action that an antagonistic force comes balance WEC.

Fig. 7 shows the detailed view on the top of yoke 2.Two arm spares 7 on the yoke 2 are connected on the respective end of a quill shaft 8.Axle 8 provides the structure connecting rod between arm spare 7, so just guaranteed that yoke 2 is structurally frameworks efficiently of a rigidity, can weight is relative to stand huge mooring load in lighter keeping.Axle 8 is arranged in a housing that is in front end 3 places of WEC 1, and is provided with a plurality of bearings 21 between axle 8 and described housing.These bearings 21 are allowed that the rotation axis 23 of described yoke threaded shaft 8 is low and are frictionally rotated 22.Also be provided with a plurality of conduits 24, they are arranged in arm spare 7 with one of axle 8 or within two.Conduit 24 allows that electric power, communication line and/or hydraulic power line or other pipeline extend between the top and bottom of yoke 2.Conduit 24 exports 25 places at one or more and passes axle 8, and wherein the flexible end portion 26 of conduit 24 is connected on the WEC 1.Flexible end portion 26 is designed to allow that the rotation axis 23 of yoke 2 threaded shafts 8 freely pivots, and makes stress minimum on inner lead or other pipeline simultaneously.Be connected with machinery all inner/outer of 1 with regard to allowing to finish with yoke 2 like this at the lower end of yoke 2.Therefore, can when being in the water, WEC 1 under the condition of the participation that need not the people, make WEC 1 be connected with mooring system/dismantle.This scheme has prevented that also described circuit is connected the invasion and attack that suffer water with other.

Fig. 8 (a) and 8 (b) show the detailed view of the lower end of yoke 2.Intersect the lower end of arm spare 7, forms turning or summit on the yoke triangular in shape basically 2.All machineries that link to each other with this machinery, electric power and/or other attaching parts all are contained in this lower end of yoke 2.These attaching partss generally comprise flexible umbilical facility supply line 27, it includes power pipeline, communication pipeline, hydraulic power line or other pipeline usually, be used for and be connected with each other than the adjacent WEC in the array layout as shown in FIG. 2, perhaps WEC is connected on the main supply line that is positioned on the sea bed.In shown embodiment, the umbilical pipeline 27 between the adjacent WEC 1 is " median water level " and is provided with.In other words, umbilical pipeline 27 is positioned at below the water surface, but does not come in contact with sea bed as yet.These umbilical pipelines 27 are connected on the connecting device that is connection box 29 forms that are installed on the yoke 2 by leak free connector 28.Connection box 29 is connected on the conduit 24, provides one to be used for various pipelines and to lead to the top of yoke 2 and enter passage in the WEC1 subsequently, as shown in Figure 7.If used two umbilical pipelines 27, to be designed to public type/parent form coupling right for connector 28 so, if thereby make certain specific WEC1 and yoke 2 owing to displacement has taken place any reason, they still can link together, so that keep the continuity of WEC array.

The bottom of yoke 2 also comprises the main frame tool that is used for tether 11 device that is connected.In illustrated embodiment, this device that is connected realized by a Hooke's coupling 30, so that allow around two vertical rotation axis free motions, and makes connecting portion wearing and tearing minimum in use.This connection utilizes a single pins 31 to realize, so that allow that described tether is carried out direct fast speed to be connected and to remove.In addition, the active redundancy pipeline (not shown) comes to keep described mooring system under the situation that any assembly breaks down integraty can be set.

The bottom of yoke 2 also has a retraction mechanism, in order to allow comparatively easily yoke 2 is retracted on the rear portion of attachment/detachment boats and ships, as the back will further describe.This retraction mechanism comprises special-shaped grooving 32 or can comprise a ball-socket and spigot joint head (not shown) alternatively or any similar connection.In addition, easy in order to help, safely yoke 2 is recycled on the boats and ships, also be provided with skid or roller 33.These allow that all described system is pullled to the afterbody of boats and ships easily, safely, and the end of yoke 2 is imported in the locking devicen.In order to help safely and fast yoke 2 to be reclaimed, can also increase other guide, roller or breech lock.

Figure 9 illustrates the tether counterweight 10 that is used in the described mooring system.Tether counterweight 10 comprises a frame unit 34, is used to be affixed to tether 11, front side anchor line 16 and any other auxiliary or standby rope (not shown).Utilize Hooke's coupling 30 to realize once more to being connected of carrying out of described various ropes, so that allow complete free motion and reduce the wearing and tearing of connecting portion.Ring on the chain cable 35 or length section suspend in midair from framework 34, produce the required weight of mooring antagonistic force so that provide, as the back will as described in.

The working process of tether counterweight 10 has been shown in Figure 10 and 11 (a)-(c).Described mooring system be configured such that when its during without undergoing any displacement force that comes from water, tether counterweight 10 perhaps partly places on the sea bed 17 as much as possible near sea bed 17.In billow, the vertical motion of WEC 1 or pitch might be very big is as shown in Figure 10 (a) and 10 (b).When the front portion 3 of WEC 1 was in ripple seam top, as shown in Figure 10 (a), tether counterweight 10 will be raised up from sea bed 17.On the contrary, when the front portion of described machinery is in trough, as shown in Figure 10 (b), tether counterweight 10 will be fallen on sea bed 17, unless enough gaps are set.

For known tether counterweight, do not wish that counterweight and sea bed come in contact.But, do not touch sea bed if do not allow described counterweight, will seriously damage described linear range of movement with the required gap of sea bed so.Tether counterweight 10 shown in Figure 9 is allowed step by step and is mentioned from sea bed, as shown in Figure 11 (a)-(c).Chain cable 35 is progressively mentioned by framework 34, has guaranteed along with the quality-smoothing of tether counterweight 10 from sea bed 17 these tether counterweights 10 of rising increases.

In Figure 11 (d)-(f), illustrated owing to known solid tether counterweight is touched the problem that sea bed produces.When solid tether counterweight 36 bump sea beds, tether 11 becomes lax.When next crest occurred, tether 11 raised up and tensioning from sea bed along with tether counterweight 36 once more, and related resultant acceleration is very high, produced the huge load of seizing on tether 11.Along with solid tether counterweight 36 is raised up from sea bed, the sucking action that it can stand once more by mud on the sea bed and sediment generation can worsen the aforementioned load of seizing that puts on the tether 11 like this.Therefore, utilize known solid counterweight 36,, on tether 11, will produce and extremely seize load along with described tether counterweight raises up from sea bed under wave action.

Figure 11 (f) shows how the load on tether described in the process that billow passes through is will be along with the time changes at two kinds of tether counterweights.Time, the tether counterweight rested on the sea bed fully by point 38 expressions, at time point 39 places, and along with described counterweight begins to be raised up from sea bed, described tether tensioning.Because the fast vertical of mooring structure quickens and the sucking action of sea bed sediment on solid tether counterweight in the wave action process, can cause solid tether counterweight to produce the huge load 40 of seizing.This load of seizing is the described tether manyfold of the rated load of contact imminent in use, therefore can cause producing damaging, and under extreme case, cause described tether to rupture.When the tether counterweight of using as shown in Figure 9, described counterweight progressively raises from sea bed, and as the chart among Figure 11 (f) shown in, and generation is less on described tether seizes load 41.

Mooring system advantage is as previously mentioned, mooring machinery or structure can be when from water, taking out split dismantling.By this way, connect or unloading process in need not operating personal and enter in the water or climb up described structure.Utilize described yoke, help realizing this operation, because described yoke is holding the connecting portion at umbilical facility pipeline and tether counterweight and anchor.Such just as will be explained, when umbilical pipeline on being connected in described tether counterweight and associated line are opened, described yoke keeps being connected on described machinery/structure, and the remainder of allowing described mooring system thus remains in the water when described structure and yoke are retracted.

In order to allow the mooring system after taking out from water to be connected and dismantle, need a recovery or withdrawal equipment that described yoke is regained from water.An example of this equipment is shown in Figure 12 (a) and 12 (b).Withdrawal equipment 45 is installed on the deck 46 of supporting boats and ships, and be provided in that remainder to described mooring system connects or the process dismantled in, maintain the end of yoke 2, as shown in Figure 12 (b).Described structure and yoke can be drawn to a solution space that is used for attended operation subsequently, and perhaps they can be promoted to and safeguard on a barge or the allied equipment or transport.

Described withdrawal equipment has a slideway 47, as the front with reference to Figure 12 and 13 described, the lower end of yoke 2 is retracted thereon.Slideway 47 has an inclined surface, and it is positioned on the slideway surface.The rear end of described slideway with respect to described slideway surface with an angle run-off the straight, so that help to reclaim described yoke.Also have, the rear portion of boats and ships itself or slideway 47 have a recovery roller or cylinder 44, in order to guarantee to reclaim reposefully or launch to be connected in various ropes and the umbilical pipeline on the yoke 2.Top end at slideway 47 also is provided with an idler roller 48, in order to guarantee that reclaiming rope 42 is pullled to its cylinder (not shown) with suitable angle and tension force.Guide plate 49 is positioned at the both sides of slideway 47, in order to yoke 2 is directed on the holding device 50 in the equipment 45.

As in Figure 13 (a)-(c) clear see, holding device 50 comprises a holding element or piece 51, has a pair of with axostylus axostyle 52 in its both sides.Piece 51 is installed on the globe bearing 53, has guaranteed that piece 51 can move (i.e. rolling, up-and-down movement or oscillating motion) on three axis.Bearing 53 and piece 51 are installed on the frame piece, and this frame piece comprises a support 54 that is installed on the balladeur train 55, as shown in Figure 14 (a) and 16 (b).

Balladeur train 55 has a plurality of rollers 57, and these rollers 57 are accommodated in one group of guide rail 56 inside, thereby makes whole holding device to vertically move with respect to slideway 47.As can seeing in Figure 14 (a) and 16 (b), guide rail 56 has first 58 and second portion 59, bottom and top in other words, and they with respect to the horizontal plane are in different angles.Bottom 58 forms a bigger angle with respect to described slideway surface, and the piece 51 that is connected when being pullled to slideway 47 with convenient yoke 2 is arranged in described slideway surface substantially.The top 59 of guide rail 56 is arranged essentially parallel to described slideway surface.

Figure 15 (a)-(d) shows the step of collecting back yoke 2.In Figure 15 (a), yoke 2 is wound on its cylinder (not shown) and is pullled to slideway 47 along with reclaiming rope 42.Utilization is arranged in the balladeur train 55 of the bottom 58 of guide rail 56, and the lower end of yoke 2 and the piece 51 that is connected come in contact.Same axostylus axostyle 52 on the piece 51 is arranged in the aforementioned grooving 32 on the yoke 2.Because the lower end of yoke 2 this moment is attached on be connected piece 51 and the balladeur train 55, and provide support, so along with the recovery rope 42 that winds up continues to pull yoke 2 on slideway 47, balladeur train 55 moves up along guide rail 56 by be connected parts 51 and balladeur train 55.Along with balladeur train 55 moves to top 59 from the bottom 58 of guide rail 56, this stage is shown in Figure 15 (b).

In every width of cloth figure of Figure 15 (a)-(d), can also see that the connection cord 11 on the main counterweight 10 still is connected on the yoke 2, and on the quarter advance on the roller 44.Withdrawal equipment 45 can also have a pallet 60 that is positioned on the slideway 47, in case so that being disassembled from yoke 2, connection cord 11 just fixes this connection cord 11, as shown in Figure 15 (c) and 17 (d).In this case, connection cord 11 has a sleeve pipe 61, and this sleeve pipe 61 is positioned at rope 11 a certain position, so that make that this sleeve pipe has been pullled and crossed pallet 60 when balladeur train 55 and yoke 2 arrive at the vertex of guide rail 56.Reclaim rope 42 and can relax subsequently, thereby make sleeve pipe 61 be suspended on the pallet 60, as shown in Figure 15 (d).Thus, the load of connection cord 11 and main counterweight 10 is removed by be connected joint 30 of the machinery from yoke 2.Be connected pin 31 and connection cord 11 can take off from yoke 2 subsequently easily and safely.

In addition, stop pin 63 can be positioned at the hole 62 of guide rail 56 both sides, so that balladeur train 55 is locked in correct position.In case this step is finished, reclaim rope 42 and also can disassemble, and WEC or other structure will directly keep by piece 51 and bearing 53 or pull from yoke 2.At this moment, any umbilical facility pipeline also can disassemble from yoke 2.Best, can utilize surface buoy or hook punt-pole, with reference to as described in Figure 16, perhaps utilize some other remote control equipment (RCE) as the back, will wave rope 14 and disassemble from WEC or structure.Yoke 2 and WEC separate with the remainder of described mooring system for 1 this moment fully.Yoke 2 and WEC get ready for pulling at this moment, as shown in Figure 12 (b).For the remainder in yoke 2 and the mooring system is reconnected, only need the reverse simply abovementioned steps of carrying out.

Figure 16 (a)-(h) shows a kind of method of supporting on the boats and ships 100 that yoke 2 and WEC 1 are recycled to.As shown in Figure 16 (a), WEC 1 is maintained by described mooring system as described above.In order to help to enter and realize under the condition in the water reclaiming need not operating personal, when yoke 2 and WEC 1 were got up by mooring, one was reclaimed rope 42 and for good and all is connected on the lower end of yoke 2.The end away from yoke 2 of reclaiming rope 42 is maintained by floating drum 102.As required, described recovery rope can have one or more counterweight group 104 and/or unsteady device 106.In the starting stage, support boats and ships 100 and arrive at floating drum 102 places.Reclaim the far-end of rope 42 and regained, and be connected on the winding drum (not shown) on the boats and ships 100 from floating drum 102.

Figure 16 (b) shows the next stage of removal process.Be connected on the described cylinder in case reclaim rope 42, floating drum 102 is retracted and places on the deck of boats and ships 100 so.Twine along with reclaiming rope 42, counterweight group 104 is raised up from sea bed, and raises towards boats and ships 100.If assembled unsteady device, this unsteady device 106 also will be along with reclaiming rope 42 generation windings and raising towards the water surface.Twined fully to make that rope 42 is no longer lax that restricting so 42 will begin to make the lower end of yoke 2 towards boats and ships 100 risings in case reclaim rope 42.Along with the lower end of rope 42 lifting yokes 2, yoke 2 is pivoted with the rotation axis 23 of threaded shaft 8, as shown in Figure 16 (c).Pivoted by yoke 2, yoke 2 will promote tether 11 and attached tether counterweight 10.As shown in Figure 16 (d), reclaim rope 42 and will continue winding, be recovered to until yoke 2 on the deck of boats and ships 100, i.e. the state described with reference to Figure 12 (b) and 15 (c) of front.

As shown in Figure 15 (d), in case described yoke 2 is attached in the mechanism 50 that is connected, tether 11 just can together disassemble from yoke 2 with any other rope or umbilical pipeline.Just sink to sea bed in order to prevent that in a single day tether 11 is removed, it is affixed on the floating drum 102, and this floating drum placed water again, promptly at the state shown in Figure 16 (e).

Carry out shown in Figure 16 (a)-(e) in the step at boats and ships 100, use second boats and ships 110 with rear side anchor 13 with wave rope 14 and disassemble from WEC 1.This point is shown in Figure 16 (f) and 16 (g), and they show the schematic end view of described mooring system and WEC1.Second reclaims or chase rope 112 is connected on the WEC 1 by first end, and is connected in by second end and waves on the rope 14.Second boats and ships 110 reclaim described first end from WEC 1, and reel and chase rope 112, as shown in Figure 16 (f).112 be wrapped on second boats and ships 110 along with chasing rope, rear side anchor 13 and wave rope 14 and also be recovered on second boats and ships 110 is as shown in Figure 16 (g).In case arrive on second boats and ships 110, rear side anchor 13 and wave rope 14 and can be removed, and be connected in and place water on the another one floating drum 114 again, as shown in Figure 16 (h).

Figure 17 (a) and 17 (b) show a kind of alternative, wherein reclaim rope 42 and are clamped on the yoke 2.Be clamped on the yoke 2 by reclaiming rope 42, need not counterweight group or unsteady device to be set at reclaiming rope 42.Reclaiming rope 42 can be unclamped from yoke 2 simply, and reclaims with the same way as of describing with reference Figure 16.

Figure 18 shows one according to mooring system second embodiment of the present invention.Mooring system among Figure 18 and aforementioned mooring system are shared many assemblies, and these functional components will be endowed identical Reference numeral, but have prefix 2.Owing to provide description in front, so need not these assemblies are carried out more descriptions to some assembly.

As previous embodiment, mooring system second embodiment shown in Figure 18 also mooring a WEC 201.This mooring system is at the front end 203 of WEC 201, and---that is to say the end facing to the direction of expection wave action or trend---has a pivot harness or yoke 202.The difference of second embodiment and last embodiment is, is fixed with first connection or counterweight tether 211A and is connected with second or counterweight tether 211B below yoke 202, and be not single connection cord.What the first connection cord 211A and the second connection cord 211B were linked together is connecting panel 212, and it will be described in the back in more detail.Main counterweight or tether counterweight 210 are suspended in midair from the second connection cord 211B.As previously mentioned, first or front side anchor line 216 be attached on the tether counterweight 210, and have first or front side anchor (not shown) of known type away from place, the end of tether counterweight 210 at front side anchor line 216.

Figure 22 illustrates mooring system the 4th embodiment among the present invention.As previously mentioned, the 4th embodiment and previous embodiment are shared many assemblies, and a WEC 401 in mooring as described above.This mooring system is at the front end 403 of WEC 401, and---that is to say the end facing to the direction of expection wave action or trend---has a pivot harness or yoke 402.The difference of the 4th embodiment and previous embodiment is, is fixed with first connection or counterweight tether 411A and is connected with second or counterweight tether 411B on second end of yoke 402.Place, end at each root connection cord 411A, 411B is fixed with corresponding main counterweight or tether counterweight 410A, 410B.Be fixed with first or front side anchor line 416 on the first tether counterweight 410A and the second tether counterweight 410B, this front side anchor line far-end has first or front side anchor 415.On each tether counterweight 410A, 410B, also be fixed with corresponding second or rear side anchor line 413A, 413B with and second attached or rear side anchor 418.Between WEC 401 and rear side anchor line 413A, 413B, also be connected with and support or wave rope 414A, 414B, be used for firm WEC 401.

The present invention allows in the large-scale mechanical array of same place installation.Help cost-cutting like this, because WEC or other structure can shared anchor points.Particularly, desirablely for WEC be, closely spaced apart.Thus, having the mooring system of fractional span between anchor point, such as the mooring system among the present invention, is useful.In addition, the mooring system among the present invention provides bigger dynamic motion scope, is enough to tackle billow like this, has reduced the extreme loads on system and the anchor simultaneously.

Described mooring system can also be to producing inhibition such as waving other such mode of motion.Allow described system response like this in the incident wave, avoided simultaneously complete rotation taking place, otherwise needs are used to carry out electric power (perhaps other) interconnective costliness and potential insecure device around the mooring axis.

Load due to described mooring system has also made up many reaction devices on sea bed, deal with different waves---perhaps trend---.The characteristics of wave load are small, stable, the variable drift load of most of times for producing on machinery/facility owing to wave action.But, in very huge extreme wave, also can stand very huge load once in a while.The small solid that weight is lighter is assisted or the counterweight group provides enough counteractions at small normal load, deals with most working conditions, and cheap, is easy to a large amount of employings.At extreme situation, utilize conventional embedding anchor, conventional suction pile, bigger counterweight group or, can effectively expand the counteraction that provides by described small counterweight by less counterweight faciation is connected.Alternatively, the heavy weight suction pile is made up of suitable component at sea bed provides two kinds of counteraction modes under the situation---and the quality of stake provides enough counteractions at small wave, and under the effect of extreme loads, the suction of stake in sea bed provides the huge impedance at the short-term substantial load.

Another one benefit of the present invention stems to have used pivot harness/yoke assembly or connected plate and described construction machine is connected on the mooring system/disassembles from mooring system.Allow that so described structure climbs up structure the personnel of need not and originally connected under on one's body the condition and dismantle on rough sea.Yoke mechanism that pivots or connecting panel can reclaiming restricts be recovered on the deck of installation/recovery boats and ships by regaining away from described machinery, and can carry out various attended operations from boats and ships subsequently with being absorbed in quite safely.This measure has alleviated the dependence of these operations to weather thus, and has reduced relevant cost and risk for allowing in the big marine very key of activity of intervening safely.The tether counterweight that described yoke assembly also gets up in conjunction with suspention provides the constraint at WEC or structure.Such just as shown in Figure 6, and particularly at WEC, described harness and tether counterweight provide the extra rolling constraint of the structure of at mooring.Since alleviated on the described structure or among be used to provide the demand of the ballast of stability in roll, so this point is useful.Alleviate size, quality and the volume that can reduce described structure to the demand of ballast, directly reduced relevant cost.

Also have, the machinery device that is connected is provided with electric power or other (such as hydraulic pressure or pneumatic) facility cross tie part on described yoke alongside, has guaranteed that these devices can be climbed up under the condition of WEC or other maritime affairs/offshore installation along with described machinery is connected the personnel of need not to connect simultaneously or dismantle.This just means that machinery adjacent in array can " median water level " couple together.That is to say, the umbilical pipeline in the condition that does not come in contact with sea bed via the lower end of described yoke with adjacent mechanical connection.Simplified installation, inspection and maintenance operation so greatly, reduced cost and improved reliability electric power or other cross tie part.

By the rear side anchor line is connected on the bottom or connecting panel of yoke, also provide a benefit.By this way, can connect described rear side anchor line simultaneously or dismantle along with main connection cord being connected or dismantling.For illustrated in WEC machinery among the embodiment, the rear side anchor line springs up suppressing unit as one, is springing up forward under the small wave action that comes from the coastal waters direction or under wave trend effect hour in order to prevent described system.Enough slackness in total system are used to allow that the lower end of described yoke or connecting panel are recovered to the deck of supporting boats and ships, and need not to move or reclaim any anchoring/reaction point.

Use is suspended on the end of yoke and the heaviness suspention tether counterweight that is connected on the principal series pool rope also is useful, because can be suppressed at system like this.The fabricate block of described yoke, tether and tether counterweight is similar to a pendulum and moves, and the position constraint at institute's mooring structure is provided.Described tether counterweight utilizes principal series pool rope to be fixed on correct position effectively.Described system provides the spring inhibit function of a kind of " softness " or poor efficiency (low-rate), is used to stop the mooring rope under extreme motion " seizing " phenomenon to take place.

The novel arrangement mode of tether counterweight used in this invention also has the advantage of known arrangements mode.By gradually reducing and reclaim the counterweight that suspention is got up, the tether counterweight among the present invention can sink to, parked and leave sea bed.This point has benefited from the segment that suspends in midair and be connected with each other.New tether counterweight can stay near sea bed (perhaps even partly placing on the sea bed), makes the length maximization of tether assemblies thus, at the given angle scope of tether/yoke with respect to vertical direction, to have increased its range of movement.Allow that like this mooring system among the present invention is used to WEC or other facility are hovered near in the shallow water area in beach/coastline and the surging wave.

Withdrawal equipment is arranged on the rear side of supporting boats and ships has guaranteed that the lower end of described yoke or connecting panel can be recovered to the rear side of supporting boats and ships under the condition that need not personnel's direct intervention.Allow the mechanical connection between remainder in described yoke or connecting panel and the mooring system and the umbilical facility pipeline like this, be connected safely from the deck of supporting boats and ships and dismantle.Thus, need not personnel climbs up on the WEC or other structure/facility that is positioned under deep-sea or the similar disavantage.

Although illustrated in tether counterweight among the embodiment be illustrated as under static state outstanding bed off sea, they also can be alternatively under static state part place on the sea bed.Also need to understand is that except or replace aforesaid conventional anchor, can use extra counterweight group or such as the anchor fitting of suction anchor or such any other form of stake.At removal process shown in Figure 16, rear side anchor and wave rope and can be removed before the tether in dismounting.By this way, same boats and ships can be finished two tasks, therefore need not second boats and ships.At last, the recovery rope that is used in the removal process can utilize the release gear of Long-distance Control to be affixed on WEC or the structure.Described rope can get loose from WEC by remote control thus, and is recovered on the boats and ships under the condition of mechanical intervention need not subsequently.These and other change and improve and under the condition that does not depart from the scope of the present invention, to carry out.
