Description
Technical field
The invention belongs to ocean platform technical field, specifically related to a kind of new ocean platform for resisting hurricane.
Background technology
Existing ocean platform species is relatively more, but, at present. for boisterous ocean platforms such as energy hurricane resistant seldom
There are spar platforms in terms of applied to marine drilling, semisubmersible platform, tension leg platform (TLP), jack-up unit, jacket platform is right
In first three, comparatively operating depth is up to deep-sea, it is also considered that to situation of the ocean platform under the sea situation for being difficult to predict, but
It is that can tackle the measure of the severe sea conditions such as hurricane still without specific.These platforms are once in adverse circumstances such as violent typhoon, hurricanes
Under will face catastrophic effect；Tension leg platform (TLP) and jacket platform also have spar platforms to be that fixed platform can not be moved
It is dynamic, difficulty is reused, it is also to deposit certainly to run into hurricane.For jack-up unit, although be mobile platform, but plug
Stake is difficult and operating depth also only reaches 120m.Can not normal work during semisubmersible platform experience severe sea condition.At present not yet
There is the ocean platform of energy hurricane resistant.
For marine petroleum development, inevitable trend deep-sea, such as China South Sea, 1212 meters of South Sea mean depth, middle part is deep
Bosom is up to 5567 meters in sea plain, and South Sea sea situation is severe, and typhoon takes place frequently.In this case, without a kind of new energy
The ocean platform for preferably adapting to the South Sea undoubtedly forms obstacle to the exploitation South Sea, and this new ocean platform for resisting hurricane
Invention will bring Beneficial Effect to the exploitation at the South Sea.
In summary, it is necessary to which a kind of new technical scheme is to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of compressing surface Secondary Flow self-loopa pneumatic type air intake duct at the same level, the air intake duct takes

Extend the sleeve pipe of spherical housing；The buoyancy tank system includes buoyancy tank, the ballast water tank water in buoyancy tank of carrying spherical housing；
When the ocean platform needs dive, ballast water tank water increases ocean platform gravity to retaining and made under spherical main and buoyancy tank
It is latent.
Beneficial effect：The present invention is a kind of new ocean platform for resisting hurricane, based on spherical housing, is broken away from
It is traditional with fixed structure, only floating platform is the limitation of the related ocean platform of carrier, makes full use of spheroid by stormy waves stream
Power influences, the advantage of uniform force small compared with other structures ocean platform, the buoyancy tank set outside spherical shell and is set in buoyancy tank lower end
Put anchoring system to efficiently solve due to the stability problem that sphere structure is brought, add the reliable of spherical structure ocean platform
Property and stability.Two kinds of working conditions of design are even more that to have broken Conventional marine platform fixed and can only float on sea and bored
The limitation of work is adopted, can be made when sea situation is more severe by ballast water tank water retaining under spherical main and buoyancy tank dive to sea,
The issuable serious consequence of working sea area severe sea condition institute is effectively prevent under technical support guarantee, when sea situation recovers good
When go up sea.
