Embodiment
It should be noted that in the case where not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Mutually combination.The present invention is described in detail with reference to embodiment.
In order that those skilled in the art more fully understand the present invention program, below by the skill in the embodiment of the present invention
Art scheme is clearly and completely described, it is clear that described embodiment is only the embodiment of a part of the invention, without
It is whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not before creative work is made
The every other embodiment obtained is put, should all belong to the scope of protection of the invention.
The invention provides connecting connection parts under a kind of deep sea vertical pipe, including be from top to bottom sequentially connected standpipe 1, chamfering
Forge link unit 2, two main stay tubes 3, connecting seat 4, flexible linkers and cast interface unit 5, supervisor 6 and lower flexible link
Device 7, described two main stay tubes 3 are abreast set, and the first side of the chamfering forging link unit 2 is provided with robot people
Mounting interface unit 8, the second side of chamfering forging link unit 2 are provided with box-shaped structural member 9, the chamfering forging link
The first end connection of the lower end of unit 2 and the inner tube 10 of U-shaped, the second end of said inner tube 10 is remote with the box-shaped structural member 9
From one end connection that the chamfering forges link unit 2, the second end of said inner tube 10 is provided with underwater connector interface unit
11。
Connecting connection parts use integrated configuration completely under deep sea vertical pipe in the present invention, have abandoned traditional in the prior art
Rectangular frame topology layout, and using the simulation result of finite element analysis as rely on, meet comprehensively under various working conditions
Intensity, the design requirement such as fatigue can not only mitigate integrally-built weight significantly, and lower processing transport significantly and be mounted to
This.
By adopting the above-described technical solution, the integrated configuration structure of the present invention is more than structure of the prior art letter
It is single, therefore overall weight can be greatly reduced.If it is considered that the operating condition design of Adjacent Sea, integrated deep sea vertical pipe bottom
Attachment means weight is between 30 tons to 70 tons.In addition, the design of the present invention has taken into full account all design conditions, design
Designed in strict accordance with the serial international standard of Offshore Engineering.According to international standard DNV-OS-F201, steel bends under high temperature
Taking intensity has certain degeneration, therefore, the present invention has had contemplated that this factor.
Although integration is of the invention simple in construction, with enough rigidity, deformation under design load can be with
It is maintained within safe range, the maximum distortion obtained through FEM calculation is completely within safe range, relative to existing
For box-structure in technology, with remarkable advantages such as low, the intensity fatigue life height of lightweight, manufacturing cost.The present invention's
Structure is completely different and box-structure of the prior art, due to the particularity of ocean engineering, for different marine sites, it is necessary to
Structural parameters are done with partial adjustment, therefore and uncertain specific all structural parameters.
Preferably, connecting connection parts also include standpipe standard shaft mounting interface unit 12 under the deep sea vertical pipe, installed in institute
At the upper surface for stating box-shaped structural member 9.
Preferably, connecting connection parts also include underwater connector supporting construction 13 under the deep sea vertical pipe, described to connect under water
Device interface unit 11 is connect to be connected with the second end of said inner tube 10 by the underwater connector supporting construction 13.
Preferably, connecting connection parts also include corrosion protection 14, each main stay tube 3 under the deep sea vertical pipe
On be respectively connected with least one described corrosion protection 14.
Preferably, connecting connection parts also include supervisor's extension tube 15 under the deep sea vertical pipe, and the supervisor 6 passes through the master
Pipe extension tube 15 is connected with the lower flexible linker 7.
Preferably, it is provided with coating 16 on the outer wall of the supervisor 6 and supervisor's extension tube 15.
Preferably, the both sides of the chamfering forging link unit 2 are also separately installed with interface support tube 17.
Too many structure is assembled under deep sea vertical pipe among connecting connection parts by prior art, therefore causes whole deep-sea
The structure of connecting connection parts is almost complicated as connecting connection parts structure on deep sea vertical pipe under standpipe.By comparison, it is of the invention
Only retain standpipe with connecting connection parts under deep sea vertical pipe to be connected, the major function of connecting connection parts under reduction deep sea vertical pipe, and
In other function differentiations to surrounding structure.So, the structure of connecting connection parts under deep sea vertical pipe can be made significantly to be simplified.
Although surrounding structure accordingly can structure more of the prior art it is slightly complicated, comprehensive advantage is that each subsystem respectively takes charge of it
Duty, is easy to design and installation, especially protrudes the partial function under the deep sea vertical pipe of most critical in connecting connection parts, fully ensures that
The reliability of whole system.
By above-mentioned technical proposal, connecting connection parts are relative to prior art under the integrated deep sea vertical pipe in the present invention
For, structure is greatly simplified, but the burden for being required to fully meet loads in plane and face external applied load of bulk strength.Meanwhile,
Thermal force caused by having taken into full account under production status is superimposed the influence produced with production status loads in plane.In addition, in design
Crude oil temperature is by the adjacent of a certain Experimental Area (for example, BP Angola Block 31) in the 118 degree of standpipes considered
The operating temperature of crude oil is determined under marine site, and design have passed through the calculating of the various load of detailed finite element, and result of calculation shows
Show, fully meet design requirement.
Deep-sea oil production technique is the weakness of China, and China is used as an energy demand big country, following marine stone
Oil exploitation has huge demand and prospect.Compared with prior art, it is an advantage of the invention that structure significantly simplifies, and more
Rationally, intensity fatigue life significantly improves, and cost can be greatly reduced in the manufacture and installation.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
