Description
Technical field
The present invention relates generally to mooring under the environmental load separation of offshore structure from mooring buoy of floating.
Background technology
Oil and natural gas-probing and the offshore industry of producing in, set up bottom and unsteady mooring structure and be used.When because for example sea ice or for example high environment influence power of the storm of hurricane, be docked in the appropriate location floating structure must from they the moorings or moorings is released and mobile.
When needing owing to the large significant threat of environmental forces to separate floating structure, preferably mooring gear keeps complete to reset after a while.
The device that the mooring gear for from them that has now at present and recommend separates floating structure is based on two basic methods.
A kind of method is to separate seriatim each mooring cable.This may cause independent mooring cable to twine.Then mooring gear must reclaim and reinstall by root.The risk that adopts this method to bring is: 1) when being released under the effect of mooring cable at tension force, the mooring cable that rebounds can impact floating structure and it is damaged, 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 is to use floating drum, and its supporting mooring gear also keeps all hawsers to be connected on the separated floating drum as one group being used for reconnecting subsequently.This method is normally based on away from the conical floating drum equipment of floating structure and make all hawsers keep being connected with separated floating drum.This makes hawser gather into one group, in contrast to independent hawser and separate, 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 that separates.
The purpose of separable mooring system is to discharge fast and the distance between moorings and the unsteady offshore structure of increasing sharply for this reason.
Generally speaking, the risk or the problem that occur on these separable devices are: 1) when expectation discharges this mechanism, and the constraint between separable mooring buoy and floating structure; 2) after mooring system is released, interconnecting between separable mooring buoy and the floating structure caused the infringement to one or two structure.
Constraint may occur, because the surface that is supposed to separate had connected a lot of years before separating trial for the first time.These two structures can be forced separately by mechanical device, but these devices must be disengaged as early as possible separating when occuring, in case stop loss harmful release gear.Another main risk is, because it is mobile alone to discharge latter two structure, but still is in the identical state that approaches, thereby they may bump one or two structure is caused damage.
When release gear was based on the conical floating drum that supports mooring, the profile that floating drum is lower was impelled the growth in faster release and gap.Load from floating structure is transferred on the mooring gear by the connection between floating structure and the buoyancy aid.For a given Design cooling load, this zone will be identical concerning the shape of any floating drum.By make separable floating drum higher and the diameter with a less (or by make highly lower one with larger diameter (figure IB), this zone may be modified.The speed of supposing vertical separation is identical, will more promptly separate than higher floating drum with the floating drum than low profile, separates rear interactional risk thereby reduced.
Therefore, it can be seen that discharging the improving equipment of offshore structure of floating in environmental load lower time from its moorings needs.
Summary of the invention
The invention solves the demand, and proposed a kind of mooring disengagement gear (mooring isolating construction) for float offshore structure and separable mooring buoy.At least one high-pressure water jet device is positioned in to float and guides water between offshore structure and the separable mooring buoy.The offshore structure that floats separates and separates with assistance with the surface that mooring buoy also provides the complementation of given shape.Can use one or more mechanical constraint equipment, offshore structure and mooring buoy link together to keep floating in normal probing or production operation.
Embody the various features of the novelty of feature of the present invention and in additional claim, at length pointed out, and form the part of the disclosure.For understanding better the present invention, and by using the operational advantage that obtains, with reference to the accompanying drawings and supporting paper, and form the part of the disclosure, a preferred embodiment of the present invention has wherein been described.
Description of drawings
In the accompanying drawing of a part that has formed this specification sheets, the sign that wherein shows in accompanying drawing reference marker similar or corresponding component is identical all the time:
Figure 1A has described high profile of the prior art and has discharged floating drum.
Figure 1B has described low profile of the prior art and has discharged floating drum.
Fig. 2-5 has schematically described the present invention and floating structure from the separation in moorings.
The specific embodiment
As can be seen from Figure 2, mooring separation equipment 10 comprise use and be connected buoyancy aid at unsteady offshore structure 16 with mooring buoy) the high-pressure water jet device 12 that is connected of the mating surfaces 14 of given shape on 18.
Should be understood that, only shown the bottom of unsteady offshore structure 16, it is lower than the water surface usually fully.Therefore, do not show the water surface related to the present invention, and be understandable that, connect and below the separation sequence generation water surface.
In the normal marine operation of oil and natural gas probing or production, mechanical connection or limiting device 20 are used for keeping unsteady offshore structure 16 and mooring buoy 18 to be locked in together.Any suitable connecting device such 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 the offshore structure that floats to be in the same place with mooring buoy.
Taper shape down 22 on the offshore structure 16 that floats preferably is used for admits the complementary shape 24 of this taper 22 to be connected with being used on mooring buoy 18.As seeing in the accompanying drawings, the receptor 24 of taper shape 22 and its complementary shape is designed to have one as much as possible less than the height of the low profile of existing design.
In operation, float offshore structure 16 and mooring buoy 18 kept together by mechanical constraint equipment 20 in probing or production operation process.When environmental concerns power caused needs to separate, mechanical restrictive device 20 was released, and high-pressure water jet device 12 activated, thereby helped to start the separation of offshore structure 16 from the mooring buoy 18 of floating.
As shown in Figure 3, mooring cable 26 assists to keep a power that causes mooring buoy 18 to turn back to its normal balance position.
Fig. 4 has described such scene: before separating fully and separate from mooring buoy 18, the power that ice produces may cause offshore structure 16 rotations of floating.But what can see is, described given shape, assist to separate than the surface of low profile.
As shown in Figure 5, by removing ballast (making its come-up) and increase ballast (it is moved down) to mooring buoy 18 from the offshore structure 16 that floats, the separation of offshore structure 16 from the mooring buoy 18 that also may be used to assist to float of ballast power.The described variation of the conventional casterangle of mooring buoy 18 is caused by the pressure at ballast power and water injector 12 places.
The invention provides several benefits of the equipment that is better than previously used separation mooring system.
It allows to make floating structure from the moorings separation under such as the environmental load of sea ice, and the top that reaches floating structure is disengaged lasting threat, and keeps simultaneously berthing accommodation complete to be connected with floating structure again.
The invention solves the tying-up problem and between the floating drum of floating structure and support berthing accommodation, kept a safety distance.
The present invention is conducive to discharge faster than prior art, thereby reduces because in the risk of the infringement in the offshore structure of the contact of deenergized period and moorings.
Method for releasing of the present invention helps to prevent from carrying the floating drum of mooring cable and the tying-up between the floating structure.
Although specific embodiment and/or details of the present invention are shown and explanation in the 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 the claim, or opposite, those skilled in the art's (comprising any and all equivalents) are known, and do not break away from these principles.
