Description
Technical field
The present invention relates to FLNG module stool, rock upper module shadow particularly to weakening FLNG under a kind of severe sea condition
The buttress system rung.
Background technology
Movably fewer and feweri with natural gas resource with landing field, exploring and develop offshore natural gas field is inexorable trend.South
Gas field, sea has quite a few to be gas field, deep-sea, marginal little gas field.For these marginal little gas field, deep-sea natural gas resource,
Under periphery relies on without facility, utilize Floating Liquefied Natural Gas (FLNG) device as a kind of novel offshore gas field development technique.
And FLNG process system is complicated, upper module gross weight is up to tens thousand of tons (more than 30,000 tons), and pretreatment and liquefaction process stream
Having many large-scale pressure vessels in journey, hull is rocked and the most sensitive by LNG, and South Sea sea conditions is very severe, if because of
Causing LNG gasification for rocking of hull, the safety of hull and crewman can be caused huge threat, product quality also cannot obtain
Ensure.Module stool is as the attachment structure of each modular architecture platform Yu FPSO main hull, and its dependable with function will
Directly affect the normal operation of FPSO production procedure.
Tradition buttress is arranged and the design of pattern can only meet the FPSO hull support demand to upper module at present, it is impossible to
Release or part release constraint (releasably along hull longitudinal restraint, it is impossible to discharge the constraint along hull cross direction), thus can not
It is effectively reduced ship motion impact.For FLNG, FLNG upper module complex process, the motion amplitude of hull is had severe
The requirement carved, especially under the sea situation of the bad environments such as the South Sea, FLNG rocks and causes process system inefficacy will cause stopping production etc.
Accident.
Summary of the invention

Buttress body and described 3rd buttress body are arranged in the side of described upper module, described second buttress body and the described 4th
Buttress body is arranged in the opposite side of described upper module；
The described first buttress body of diagonal layout and described 4th buttress body, the upper table of one of them buttress body
Face and upper module pillar sliding contact, the upper surface of another buttress body is fixing with upper module pillar to be connected, and vertically
It is provided with and is positioned at the baffle plate arranged outside upper module pillar, in groined type；
The described second buttress body of diagonal layout and described 3rd buttress body, the upper table of one of them buttress body
Face and upper module pillar sliding contact, and be vertically arranged restricted described upper module along captain direction and move along beam direction
Baffle plate, the upper surface of another buttress body and upper module pillar sliding contact, and be vertically arranged limited along beam direction
Make the baffle plate that described upper module moves along captain direction.
Described first, second, third and fourth buttress body is all for the truncated rectangular pyramids type structure being made up of five steel plates.
The height of described first, second, third and fourth buttress body is 4～5m, and the length and width of its upper surface is equal
Being 1.5～2m, the length and width of its bottom surface is 2～4m.
Described first, second, third and fourth buttress body be internally provided with vertical with buttress body upper surface and in
The internal reinforcing plates that cross is arranged.
The height of described baffle plate is 100～300mm.
The invention has the beneficial effects as follows: in the present invention, be positioned at the buttress of four angle points of upper module respectively to upper module
Take different constraints (moving freely, limit lateral movement, limit lengthwise movement, limit all displacements), can effectively release
Put constraint, reduce the FLNG motion impact on upper module, improve working performance coefficient overall for FNLG and safety coefficient.
