Description
Technical field
The utility model relates to a kind of semisubmersible platform, has the semisubmersible platform than high stability under particularly a kind of high sea condition.
Background technology
In recent years, we develop marine oil just progressively by shallow water to deep-water developments, the oil production platform also is tending towards maximizing gradually, and adopts the float structure form, half submerged floating platform then is wherein a kind of.Waters, marine site, China South Sea is big, it is many to verify hydrocarbon resources, exploitation South Sea oil gas is different from employing the fixed platform version in the Bohai Sea, promptly adopt floating structure, half submerged floating platform is exactly one of them, half submerged floating platform uses decades in the marine petroleum development at home and abroad, and especially semi-submersible drilling unit occupies the majority.At present the floating platform of exploitation marine site, China South Sea hydrocarbon resources will have following characteristics: Anti-Typhoon, operating water depth is big, function is complete, be fit to China's manufacturing level of processing, along with the larger hydrocarbon field constantly is found, we are outstanding day by day to large-scale floating production of hydrocarbons device demand.Therefore, we need a kind of new technique and equipment, to satisfy the hydrocarbon resources exploitation of marine site, the South Sea.
According to the hydrocarbon resources development research of existing marine site, the South Sea, a platform will have the oil gas of several ten thousand tons of weights to handle and relevant device, therefore need a kind of maximize and Anti-Typhoon floating structure as carrier, to satisfy the continuous safety in production job requirements that reaches 20～30 year producing life.Therefore, we need a kind of novel semisubmersible platform device that satisfies marine site, South Sea operating feature and be suitable for oil and gas development.
Summary of the invention
The purpose of this utility model provides a kind of semisubmersible platform, and this platform can improve the stability of high sea condition lower platform.
A kind of semisubmersible platform that the utility model provides, it comprises two following buoyancy aids; Two horizontal braces that connect described two following buoyancy aids; Four junctions of described two following buoyancy aids and described two horizontal braces respectively are provided with a column; Be arranged at four decks on the column; The described deck of connection one end of at least one column is centroclinal to described flat-bed in described four columns, uprights between this bevelled knuckle place and described buoyancy aid down and the described horizontal brace junction is divided into the vertical section of described column, and the uprights between this bevelled knuckle place and the described deck is divided into the tilting section of described column; Described knuckle place at the mid point of described column on the upper side between 1/3rd places.
Between the above-mentioned semisubmersible platform, described down buoyancy aid and described horizontal brace is to captive joint; Between the vertical section of described column and described down buoyancy aid and the described horizontal brace junction is to captive joint; Between the tilting section of described column and the described deck is to captive joint.
Above-mentioned semisubmersible platform, described is parallel between the buoyancy aid down; Be parallel between the described horizontal brace.
Above-mentioned semisubmersible platform, the described deck of connection one end of at least two columns is centroclinal to described flat-bed in described four columns.
Above-mentioned semisubmersible platform, described knuckle place is positioned on the same horizontal surface.
Above-mentioned semisubmersible platform, the tilting section of described column are 15 to spend to 35 degree with respect to the angle of inclination of the vertical section of described column, and described angle of inclination is identical.The inclined degree of column is controlled at 15 spends, the elevator of conveying people and goods can be set in described column like this, and assurance elevator freedom in described column works up and down, thereby can increase work efficiency to 35 degree.
Above-mentioned semisubmersible platform, the described deck of the connection of described four columns one end is centroclinal to described flat-bed.
Above-mentioned semisubmersible platform, described deck are plane box-structure or space truss formula structure.Deck construction is used to support oil gas treatment facility or drill outfit.
Because it is big more the closer to the water surface wave application force, therefore pillar construction suffers wave force bigger than the square structure that following buoyancy aid and horizontal brace are connected to form, and the part of the pillar construction on the water surface also is subjected to wind effect, therefore pillar construction on the water surface is designed to help wave absorbing function under the wave condition to the centroclinal mode of platform, reduced the slamming application force of wave column, improved semisubmersible flat-bed stability under the high sea condition, made it be more suitable for marine site, China South Sea characteristics that waves whipped up by the wind rolled turbulently.The elevator of personnel and goods transport can be set in the pillar construction of semisubmersible platform of the present utility model, and convenient production improved work efficiency.Therefore, semisubmersible platform of the present utility model can be widely used among the marine petroleum development, is to reduce platform operating risk and the effective technology means that improve the oil-gas field development benefit, has broad application prospects.
