Description
Research field：
The present invention relates to a kind of ocean deepwater technical field of operation more particularly to a kind of applied to semisubmersible drilling platform
Device.
Background technology：
Wide ocean is richly stored with petroleum resources, is exploited with marine oil and gas from offshore waters and has evolved to depth
Saline waters, the platforms such as traditional jacket and gravity type are not suitable for abyssalpelagic due to dead weight and the significantly increase of cost
Oil-gas mining.In recent decades, by the research to novel ocean platform, with tension leg platform (TLP) (TLP), float-type platform
(SPAR), the flat forms such as semisubmersible platform (SEMI), floating vessel type (FPSO) are exploited suitable for deep-sea oil gas, operate mainly in ink
The deep sea waters such as Xi Gewan, Brazil, West Africa, the North Sea.
Compared with TLP and SPAR, semisubmersible platform is relatively fewer with gross investment, and the space that deck possesses bigger simultaneously can
Bear changing load, have stronger production capacity, the operating depth range of bigger, be easy to be transformed and have drilling well, well workover, life
A variety of work functions such as production, without Attention problems, the round-the-clock ability to work in the whole world and the advantages of deposit ability etc. certainly.It is based on
Many-sided comprehensive considerations such as cost of investment, operating depth range, well head number, the length of service and work region, semisubmersible platform
It is a kind of drilling platforms for being relatively specific for deep sea waters exploitation petroleum resources.
Semisubmersible drilling platform is a kind of deep sea drilling platform being widely used, capacity of anti-storm in worldwide
It is suitable for ocean deepwater operation by force.Existing semisubmersible platform provides buoyancy by two buoyancy tanks for platform, and each buoyancy tank supports
Two vertical columns, the apical support deck of column, the drilling platforms of this structure during the work time, the drinking water of platform compared with
Shallow, rolling and pitching amplitude are smaller, but the amplitude of heaving is larger, and the stability of platform is destroyed, in heaving
In this way under the action of cyclic loading, the standpipe of ocean platform is also susceptible to fatigue damage.Therefore, inhibit semisubmersible platform heaving
The technique study of movement has important engineering background and practical significance.
Research shows that the heaving of platform can be inhibited equipped with heave plate below semisubmersible platform.Heave plate is also deposited
In different form, the heave plate of each form inhibits the effect difference of heaving, and traditional heave plate is generally fixedly connected
Under platform below floating body, there is different forms for heave plate, and the effect of the heave plate inhibition heaving of each form is different,
The heaving under working platform state is alleviated to some extent.
But semisubmersible platform, under towing condition, the strong incoming of towage causes vortex to be detached from, and generates the liter of periodic vibration
Power acts on, make in underwater column and heaving plate truss structure under lift effect with certain frequency and amplitude vibration, i.e.,
The phenomenon that producing vortex-induced vibration, this phenomenon can make semisubmersible platform be in underwater structure and standpipe by larger alternation
Stress, so that generating fatigue damage.Meanwhile heave plate below semisubmersible platform floating body and lattice supporting framework are immersed in
In seawater, larger towage resistance is easily generated, towage resistance will be to the operation timeliness of semisubmersible platform and fuel consumption etc.
Aspect has an impact.
