Abstract
The present invention relates to a multipurpose semisubmersible offshore platform for resisting typhoon, which belongs to a floating production system of offshore oil. The offshore platform comprises a single point mooring device, an oil gas producing and processing device, and a storage system. The present invention is characterized in that the offshore platform is composed of a polygonal lower floating body welded from a plurality of huge double-layer columns with the diameter of 20 to 30 meters, a vertical cylindrical upper floating body with the diameter of 20 to 30 meters, an upper deck building at the top part of the upper floating body, etc.
Description
Multi-purpose semi-submerged offshore platform for typhoon resistant belongs to the marine oil floating production system, and it comprises single point mooring unit, production of hydrocarbons, processing equipment and storage system.
Existing marine oil floating production system, its production of hydrocarbons, processing, storage, mooring gear or system are what independently separate, as oil gas * produce, processing equipment be provided in a side of on platform or the boats and ships, * system adopts mammoth tanker or oil barge, and single point mooring unit is to be fixed in certain a bit or with anchoring with steel *.Such marine floating type production system wind loading rating is poor, run into severe sea condition arrivings such as typhoon, must withdraw the scene rapidly, thereby make production sink into to pause, oily stream solidifies in the pipeline because of stopping production suddenly will cause for containing the big oil product of cured matter height, viscosity, the infringement total system.Begin to develop new floating production system recently abroad, the big float-plane version platform (seeing Norway Trosvik company profile (nineteen eighty-two)) that production, storage, the mooring of studying as Norway is integrated in one, form by upper and lower two big column housings, top cylindrical shell diameter is less than the lower cylindrical diameter of the housing, extended water surface support deck, the diameter of bottom big column housing reaches 70 meters, in order to store oil.Huge cylindrical shell like this, general shipyard does not possess working condition, and the technological requirement height, costs an arm and a leg, and is difficult to realize, and existing this project still is in conceptual phase.
Task of the present invention is that a kind of energy of proposition is Anti-Typhoon, the resettlement that need not stop production before typhoon arrives, and less demanding to the working condition of its construction, technology difficulty is little, easily the new floating offshore oil production system that realizes.
The present invention is the Anti-Typhoon versatile platform of a kind of semisubmersible, hereinafter to be referred as " multipurpose ocean platform ".It by following buoyancy aid 9., 6. upper float reach three main portions in deck and form, wherein descend buoyancy aid 9. is to be welded by a plurality of large cylindrical housings, each cylindrical shell diameter is 20-30 rice, growing is 35-55 rice.Following buoyancy aid all sinks to 50-60 rice under water.Following buoyancy aid is polygon, can increase the damping moment of multipurpose ocean platform in seawater.Upper float is a vertical cylinder housing, and its diameter is a 20-30 rice.Connected by many struts between the upper and lower buoyancy aid, the strut diameter is got 3.5-4.0 rice.The upper float top is the deck, be provided with on the deck living quarterss such as personnel's accommodation 5., the autogyro platform 4., the combustion of natural gas tower 1., hoisting crane 2., 3. the oil transportation tower reach fire life-saving equipment etc.
For making full use of the space, lower the center of gravity, oil gas treatment facility, pump room, dynamo room etc. are arranged in the upper float.
The multipurpose ocean platform is connected with the seabed pipe by soft pipe, and when the multipurpose ocean platform moved within the specific limits, it can be not destroyed with being connected of seabed pipe.
Crude oil flows into down buoyancy aid after treatment.Following buoyancy aid is a double hull, is ballast chamber between shell and the inner casing; Inner housing is inner to be the store oil cabin.When handling oil stream injection store oil cabin, back, an amount of ballast water of the then corresponding discharge of ballast tank.Vice versa.Multipurpose ocean flat-bed height of gravitational center is remained in a certain specialized range, thereby satisfy its floading condition requirement.The interior store oil of inner housing is significant at secure context, and promptly when marine accident took place, crude oil can not leak and contaminated environment.
The multipurpose ocean platform adopts many anchor chains to be radial anchoring, does the time spent at wind and tidal wave, drift phenomenon can not take place.
The multipurpose ocean platform is applicable to that reserves exploit the time limit not quite, continuously and be no more than the oil field in 10 years, and the true oil field of exploitation unclear prospect.Its more existing floating production system wind loading rating is strong, safe and reliable, meets typhoon and need not move the production efficiency height.As to design crude output be 3000 tons/day oil field, adopts existing floating production system, stops production when withdrawing from receiving typhoon forecast, only resume production again later to typhoon, about about 4 days time, as being subjected to typhoon influence 4-5 time every year, will produce crude oil 48000-60000 ton the whole year less; Adopt the multipurpose ocean platform only at typhoon through out-of-date stopping production one day, typhoon one is crossed and can be resumed production immediately.Both compare, and employing multipurpose ocean platform every year can voluminous crude oil 41000-53000 ton.
The big float-plane version offshore platform of multipurpose ocean platform and Norway's research compares, and less demanding to the production facility of building, the shipyard with good water area condition all can be produced, and because of rational in infrastructure, cost is also lower, is convenient to promote.

The multipurpose ocean platform can be divided into deck, upper float, three main portions of buoyancy aid are built respectively down, close up greatly on the water then, floor space and structure thereof can be determined according to the arrangement requirement of equipment, bin etc., adopt the method for construction of conventional grillage to realize.Upper float cylindrical shell method of construction is routinely realized on building berth.Following buoyancy aid is bulky, can adopt earlier each cylindrical shell of buoyancy aid under forming is built on building berth respectively, send down water then, builds with the method for closing up on the water.
