The platform is of a buoyant-tower-type structure, comprises an upper layer building module and is characterized in that the platform further comprises a buoyant tower and a suction anchor, the upper layer building module is connected with the buoyant tower through a connecting supporting leg, and the suction anchor is arranged at the lower end of the buoyant tower and is of a structure with a sealed upper opening and an open lower opening. The buoyant-tower-type ocean platform is low in manufacturing cost, has small dependence on a maritime work supporting ship when used, is low in cost and is very suitable for drilling development and production processing of oil gas in the offshore seas.
Description
Technical field
The present invention relates to a kind of platform, especially a kind of platform that uses in offshore sea waters.
Background technology
In prior art, relating to the drilling-production platform using offshore sea waters has:
1. jacket platform, the feature of this platform be jacket first after land is prefabricated, haul is to marine installation in position, then along conduit, drive piles, stake is to make a call to a joint to connect a joint, finally in the annular space between stake and conduit, pours into cement wash, makes stake be connected and be fixed on seabed with conduit.The integral structure rigidity that this platform advantage is jacket platform is large, is applicable to various soil properties, and sea meteorological conditions is less on its impact, and purposes is wide.Its shortcoming is poor mobility, can not repeated usage, and along with the increase of the depth of water, the cost of platform will sharply increase.
2. mat type jack-up drilling unit, the feature of this platform is by a upper platform, several spud leg and stake that can lifting
The offshore platform that the public mat in one of leg below forms.During work, mat falls within seabed, and liftable post leg is raised to the above certain altitude in sea by platform, supports whole platform and carries out drilling operation at sea.The advantage of this platform is good stability, and movability is good, and alerting ability is good, can be used for the marine site of larger depth of water scope.Its shortcoming is to soil property restricted (being only applicable to weak soil soil property), and seabed plane requires smooth.
3. spud leg type jack-up drilling unit, the feature of this platform is by a upper platform and several offshore platform of forming of spud leg that can lifting.During work, spud leg inserts seabed, and liftable post leg can be raised to platform the above certain altitude in sea, supports whole platform and carries out drilling operation at sea.Its advantage is good stability, and movability is good, and alerting ability is good, is applicable to the marine site of various soil properties and larger depth of water scope.When its shortcoming is work, also need a fixed platform to coordinate with it, purposes has limitation (generally only for drilling operation), and cost is higher.
4. gravity platform, the feature of this platform is to be all generally reinforced concrete structure, as the large-scale versatile platform that recovers the oil, stores and process.Bottom is a huge concrete caisson, with three to four hollow concrete columns, is supporting platform structure.Caisson is split into a plurality of oil storage chambers and ballast tank.Its advantage is to save steel, good economical benefit, and deck load is large, and anti-marine corrosion, fire prevention, explosion-proof performance are all good, and maintenance load is little, and expense is low, long service life.Its shortcoming be to ground require highly, manufacturing process is complicated, resistance in towing is large.
Summary of the invention
Technical matters to be solved by this invention has been to provide a kind of Novel ocean platform for offshore sea waters, for the exploitation in Offshore Oil gas field provides a kind of new scheme, following by by the further developing of this design, this technology can also be carried out in 200 to 700 feet of dark waters more exploration and exploitation.This platform is a kind of novel platform, and this design is fixed in anchoring mode, without jacket fixed platform is installed, extra large work is supported to the dependency degree of ship is low.This platform is mainly used in the probing development and production of offshore sea waters oil gas and processes.
In order to solve the problems of the technologies described above, the invention provides the tower platform of a kind of like this buoyancy, comprise superstructure module, also comprise floating tower, suction anchor, described superstructure module is connected with Fu Ta by connecting adjustable brace, described suction anchor is arranged on the lower end of floating tower, and described suction anchor is sealing suitable for reading, end opening open design.The design of this platform buoyant tower structure and suction anchor, has good stability, wind-proof and wave-proof antidetonation, steel using amount is few, cost is low and the advantage such as reusable.Whole platform adopts the fixed form of suction anchor, and suction anchor is positioned at Fu Ta lower end, during work, utilizes the weight of floating tower self that suction anchor end opening is inserted in sea bed whole platform is fixed.When platform need to move to another work area, suction anchor is extracted out in sea bed, use towboat that buoyant tower platform movement is arrived to another place, and be fixed by mode of operation noted earlier.This platform cost is low, easy to use, the very suitable operation of being correlated with in offshore sea waters.
Further improvement project as technique scheme: the top at suction anchor is provided with suction tube, can be by the air sucking-off of suction anchor inside by suction tube after suction anchor inserts in sea bed, make the inner vacuum that forms of suction anchor, under the effect of bar pressure, make the more deep of suction anchor insertion, fixed effect is better.
Further improvement project as above-mentioned two kinds of technical schemes: described floating tower comprises four cabins, adjacent two cabins interconnect by strengthening gusset.Adopt four cabins to be combined into integral body and form floating tower, can better bear from stress laterally and longitudinally, shared corresponding failure risk simultaneously, avoided the situation of the whole platform of monomer cabin fault effects.
As the further improvement project to cabin: described cabin comprises sky cabin, variable ballast tank and permanent ballast tank, and described variable ballast tank is positioned at the centre of sky cabin and permanent ballast tank.Permanent ballast tank can pour into the weights such as cement as Fixed Ballast, and the center of gravity in whole cabin is reduced, and in water, can better hold up; The materials such as variable ballast tank filled water, for regulating the centre of buoyancy in cabin; Empty cabin is for whole cabin provides buoyancy.More easy to operate while adopting the cabin of this structure to install at sea.
As the further improvement project to all technical schemes: described Fu Ta side is provided with riser cradle, is provided with drilling riser pipe in described riser cradle.Increasing this structure can make platform in coastal waters, carry out mud oil work.
In a word, the tower platform manufacturing price of buoyancy of the present invention is cheap, in use procedure, extra large work is supported to the dependency degree of ship is low, and expense is little, and the probing development and production that is highly suitable for offshore sea waters oil gas is processed.
