Description
Technical field
The present invention relates generally to the separation of the mooring floating offshore structure under environmental load from mooring buoy.
Background technology
Oil and natural gas-probing and produce offshore industry in, set up bottom and floating mooring structure used.When the high environmental impact of the storm due to such as sea ice or such as hurricane, the floating structure being docked in appropriate location must be released from their moorings or moorings and move.
When needing due to the large significant threat of environmental forces to be separated floating structure, preferably mooring gear keeps complete to reset after a while.
Existing at present and recommend be based on two basic methods for being separated the device of floating structure from their mooring gear.
One method is separated each mooring cable seriatim.This may cause independent mooring cable to be wound around.Then mooring gear must reclaim by root and reinstall.Adopting risk brought in this way is: 1) when mooring cable is released under tension, the mooring cable rebounded can impact floating structure and damage it, and 2) to reclaim each root hawser and reconnect respectively be very time-consuming.This way is especially impracticable in the waters of snow and ice cover.
Second method uses floating drum, and its supporting mooring gear also keeps all hawsers to be connected on separated floating drum as one group for reconnecting subsequently.This method normally based on away from floating structure conical floating drum equipment and make all hawsers and separated floating drum keep being connected.This makes hawser be polymerized to one group, in contrast to independent hawser and be separated, but d/d float-level height is by the restriction of the ship side size of d/d floating watercraft.This may cause floating drum must continue the long period to remove the floating structure be separated.
The object of separable mooring system discharges and the distance increased sharply between moorings and floating offshore structure fast for this reason.
Generally, occur in risk on these separable devices or problem is: 1) when expecting this mechanism of release, the constraint between separable mooring buoy and floating structure; 2) after mooring system is released, being interconnected between separable mooring buoy and floating structure result in the infringement to one or two structure.
Constraint may occur, because the surface being supposed to be separated had been connected to a lot of year before first time is separated trial.These two structures can be forced separately by mechanical device, but these devices must be removed, in case stop loss harmful release gear as early as possible when being separated and occurring.Another main risk is, move alone owing to discharging latter two structure, but still be in identical close state, they may collide thus cause damage to one or two structure.
When release gear is the conical floating drum based on support mooring, the profile that floating drum is lower impels the growth in release and gap faster.Load from floating structure is transferred on mooring gear by the connection between floating structure and buoyancy aid.For a given Design cooling load, will be identical concerning this region the shape of any floating drum.By making separable floating drum higher with a relatively little diameter (or by make highly lower one with larger diameter (figure IB), this region may be modified.Suppose that the speed of vertical separation is identical, more promptly will separate than higher floating drum with the floating drum compared with low profile, thus interactional risk after reducing separation.
Therefore, it can be seen, discharging improving equipment of floating offshore structure from its moorings time under environmental load is needs.
Summary of the invention
The invention solves the demand, and propose a kind of mooring disengagement gear (mooring isolating construction) for floating offshore structure and separable mooring buoy.At least one high pressurised water jet is positioned between floating offshore structure and separable mooring buoy and guides water.Floating offshore structure and mooring buoy also provide the surface of the complementation of given shape to assist be separated and separate.One or more mechanical constraint equipment can be used, to keep floating offshore structure and mooring buoy to link together in normal probing or production operation.
The various features embodying the novelty of feature of the present invention are pointed out in the accompanying claims in detail, and are formed as the part of the disclosure.For understanding the present invention better, and by using the operational advantage obtained, with reference to accompanying drawing and supporting paper, and being formed as the part of the disclosure, which describing a preferred embodiment of the present invention.
Accompanying drawing explanation
In the accompanying drawing of a part defining this specification sheets, the sign wherein shown in accompanying drawing reference marker that is similar or corresponding component is identical all the time:
Figure 1A describes high profile release floating drum of the prior art.
Figure 1B describes low profile of the prior art release floating drum.
Fig. 2-5 schematically depict the separation from moorings of the present invention and floating structure.
Detailed description of the invention
As can be seen from Figure 2, mooring separation equipment 10 comprises the high pressurised water jet 12 using and be connected with the mating surfaces 14 of the given shape on floating offshore structure 16 and mooring buoy (buoyancy aid) 18.
Should be understood that, only show the bottom of floating offshore structure 16, it is usually complete in the water surface.Therefore, do not show the water surface related to the present invention, and be understandable that, connect and the separation sequence generation water surface below.
Water jet blower 12 is preferentially provided on the hull 16 of floating offshore structure.Interval between the water capacity of water jet blower 12 and pressure, number and water jet blower 12 is determined by the size of floating offshore structure 16 and mooring buoy 18.
In oil and natural gas probing or the normal marine operation of producing, mechanical connection or limiting device 20 are for keeping together with floating offshore structure 16 is locked in mooring buoy 18.Any suitable connecting device, as hydraulic ram or pinion and-rack jacking equipment, can be used as mechanical connecting device 20.
Ballast power (power of ballace) also can impel floating offshore structure together with mooring buoy.
Taper shape 22 down on floating offshore structure 16 be preferably used to on mooring buoy 18 for receiving the complementary shape 24 of this taper 22 to be connected.As seen in the accompanying drawings, conical 22 are designed to have the height that is less than the low profile of existing design as much as possible with the receptor 24 of its complementary.
In operation, floating offshore structure 16 and mooring buoy 18 are kept together by mechanical constraint equipment 20 in probing or production operation process.When environmental impact causes needing to be separated, mechanical restrictive device 20 is released, and high pressurised water jet 12 activated, thus helps to start floating offshore structure 16 from the separation mooring buoy 18.
As shown in Figure 3, mooring cable 26 assists the power that maintenance one causes mooring buoy 18 to turn back to its normal balance position.
Fig. 4 describes such scene: before being separated completely from mooring buoy 18 and separating, and the power that ice produces may cause floating offshore structure 16 to rotate.But, it is seen that, described given shape, compared with low profile surface assist be separated.
As shown in Figure 5, by removing ballast (making it float) from floating offshore structure 16 and increasing ballast (making it move down) to mooring buoy 18, ballast power also may be used to assist floating offshore structure 16 from the separation mooring buoy 18.The described change of the conventional casterangle of mooring buoy 18 is caused by the pressure of ballast power and water injector 12.
The invention provides several benefits of the equipment of the separation mooring system used before being better than.
It allows to be separated from moorings under the environmental load of such as sea ice to make floating structure, and lasting threat is removed on the top of floating structure, and keeps berthing accommodation complete to be connected with floating structure simultaneously again.
The invention solves tying-up problem and maintain a safety distance between floating structure and the floating drum supporting berthing accommodation.
The present invention is conducive to discharging faster than prior art, thus reduces the risk due to the offshore structure of the contact at deenergized period and the infringement in moorings.
Method for releasing of the present invention contributes to the tying-up preventing from carrying between the floating drum of mooring cable and floating structure.
Although specific embodiment and/or details of the present invention have been shown and have illustrated above, to describe the application of the principles of the present invention, will be understood that, this invention can be specific owing to describing more fully in claim, or it is contrary, those skilled in the art's (comprising any and all equivalents) are known, and do not depart from these principles.
