Description
Technical field
The present invention relates to a kind of tension leg platform (TLP).
Background technology
Tension leg platform (TLP) development in practice, basically forms a kind of typical single column or four pillar construction forms.
The main thought of tension leg platform (TLP) design is the structure by self, produces the buoyancy much larger than dead load, buoyancy
In addition to offsetting deadweight, remainder becomes surplus buoyancy, and this part buoyancy balances with pretension.
Conventional four column platforms, large-scale especially with public utilities such as rig, oil vapor treatment equipment, electromotors is combined
Closing platform, due to column number quantitative limitation, drinking water is relatively big, and Water Plane is less so that platform docking, towage and sea
The operating modes such as installation need the biggest cost and risk.And large-scale tension leg platform (TLP) is typically in the center of whole oil gas field group
Position, a lot of oil gas field of periphery needs to rely on its ability effective exploitation, and the requirement of its safety is higher.
The pretension of tension leg is the least, then can reduce the overall cost of platform.Typical tension leg platform (TLP) is in order to provide
Bigger restoring force and buoyancy, as structure is optimized, by sub-surface buoy by extension tension leg platform (TLP) (ETLP)
Stretch out, form cantilever beam structure so that construction weight increases and builds more complicated.
In order to chunk and hull are docked at harbour, in order to realize the overall towage of platform, platform needs tool
Have enough buoyancy, and a platform after overall docking, install and in transportation center of gravity higher, reduce platform
Stability, in order to solve this problem, some companies employing " interim stability module " (Temporary stability modules,
It is called for short TSM), to make up stability loss.
Summary of the invention
It is an object of the invention to provide and a kind of there is enough stability, the tension leg platform (TLP) of big floor space, can be as greatly
Type drilling well and processing platform.
A kind of tension leg platform (TLP) provided by the present invention, it includes hull, Texas deck and tension leg；
Described hull includes 6 root posts and 6 buoyancy tanks, and the head and the tail of described buoyancy tank are connected with one end of described column,
Form a ring-type described hull；
Described Texas deck is arranged on described hull, and away from described buoyancy tank end；
The bottom of described column connects described tension leg, and the other end of described tension leg is for being connected with seafloor foundation.
Due to the fact that and be positioned at underwater higher depth, so described buoyancy tank is affected less by water surface wave power；Along with institute
State the increase of column quantity, it is provided that platform keeps the enough Areas of Water Plan needed for stability.
In the present invention, described hull is fixed by seafloor foundation, mainly has pile foundation, suction type foundation, gravity type foundation
Or the pattern such as composite foundation.
In above-mentioned tension leg platform (TLP), every described column connects 1～3 described tension leg.
In above-mentioned tension leg platform (TLP), every described column connects 2 described tension legs, for hanging 12 tension force
Routine four column platform of lower limb, the layout of six post tension leg platform 6 column × 2 piece tension legs, it is better than 4 column × 3
The layout of root tension leg.Bigger restoring force can be provided time not only in place, it is ensured that platform exercise performance, simultaneously by
Increasing in column, improves the redundancy of tension leg so that platform has more in the case of single tension leg is disrumpent feelings
Good survival ability.
In above-mentioned tension leg platform (TLP), described hull is hexagonal.
In above-mentioned tension leg platform (TLP), the cross section of described column is rectangular or circular；
The cross section of described buoyancy tank is rectangular.
In above-mentioned tension leg platform (TLP), described Texas deck is global formation or split molding.
Bank can be arranged at the center of Texas deck, can support dry tree system, production riser passes through bank with upper
Portion's equipment is connected, and bottom connects with sub-sea drilled wells.
Hull in the present invention can select to build at dry dock, it is also possible to ground, workshop, sea is built by land.Platform upper
Deck, portion can also be divided into several modules as a single module and build.
Texas deck and the assembling of hull in the present invention can complete in harbour or dock and debug, without
To cover deepwater field or sea is carried out, thus to avoid the operation on the sea of offshore.
The tension leg platform (TLP) of the present invention can allow superstructure (such as Texas deck, be provided with production of hydrocarbons process, public,
The facilities such as life) carry out harbour with hull and dock, the platform entirety towage after docking to erecting bed and is installed, institute
Having operation the most not use temporary buoy or other professional equipment, Attention problems is without large-scale floating crane.The 6 of present invention setting
Column × 2 piece tension leg, can provide bigger restoring force, it is ensured that platform exercise performance time not only in place, simultaneously by
Increasing in column, improves the redundancy of tension leg so that platform has more in the case of single tension leg is disrumpent feelings
Good survival ability.

In figure, each labelling is as follows: 1 column, 2 buoyancy tanks, 3 tension legs, 4 Texas decks.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings, but the invention is not limited in following example.
As shown in 1 and Fig. 2, one six post tension leg platform that the present invention provides, this platform includes six roots of sensation column 1
With six buoyancy tanks 2, wherein, column 1 is cylindrical, and buoyancy tank 2 is cuboid.The head and the tail of buoyancy tank 2 are all with vertical
One end of post 1 is connected, and then forms a hexagonal circulus.Column and the increase of buoyancy tank quantity, expand
The principal dimensions of platform, it is provided that more buoyancy, reduces surplus buoyancy so that platform drinking water is more shallow, water simultaneously
Line face is bigger, improves the stability of platform.
As shown in Figure 5 and Figure 6, the bottom of each buoyancy tank 2 connects 2 tension legs 3, and tension leg 3 is connected to seabed
Basis.Due to the increasing of principal dimensions, each tension force tendon can provide bigger restoring moment, and every tension leg 3 is by 3
Root tension force tendon forms.
As shown in figures 3 to 6, Texas deck 4 is arranged on hull, and away from one end of buoyancy tank 2.Texas deck 4
Rectangular, bank is centrally located.The increase of principal dimensions, makes Texas deck 4 can provide bigger placement-face
Long-pending, it is suitable for machinery and processing platform.Column 1 and buoyancy tank 2 make to provide bigger buoyancy, it is ensured that after docking
Less drinking water so that Texas deck 4 can complete and the achieving a butt joint of platform hull at harbour.
Time as disrumpent feelings in platform generation wall scroll tension leg, its arrangement of 6 × 2, it is ensured that the redundancy of platform alignment system
Degree.Article 11, it is arranged in the complete tension leg of 6 root posts so that it is there is enough survival abilities.
