Description
Technical field
The present invention relates to the field of support structures of subsea blow out preventer, and in particular to a kind of in subsea blow out preventer supporting construction
Load test method.
Background technology
The supporting construction of ocean engineering ship, marine drilling platform and FPSO subsea blow out preventer (BOP) is when using, it is necessary to enter
The load test of row stressed member and hanger, it is safe and reliable when supporting construction scene is actually used to determine, and then protect ocean
Environment.
In ocean engineering, BOP is the emergent management equipment that offshore oil production operation is protected the marine environment, when BOP is used, its
The load that supporting construction undertakes would generally reach 600T (ton), and in deep-sea, the carrying of the supporting construction of BOP is even above
1000T。
At present, domestic manufacturers mainly complete the stressed member of supporting construction and the load test of hanger, state on puller system
Outer manufacturer generally carries out load test using special fitting device and equipment.But, domestic heavy load puller system is mainly used in
The inspection work of steel wire rope, anchor chain bearing capacity, large-scale shipyard and structural member manufactory will not typically be equipped with heavy load puller system；
Therefore, it is domestic in the case of without external special fitting device and equipment, it is impossible to which that the supporting construction to BOP carries out load examination
Test, and then hinder the manufacture of BOP and use.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of support for subsea blow out preventer
The load test method of structure, the present invention ensure that the flatness of BOP supporting constructions while experimentation cost is significantly reduced
And intensity, conventional efficient can not only be improved, shorten the construction period of supporting construction, and also operation is fairly simple, is easy to people
Use, be easy to promote.
To achieve the above objectives, provided by the present invention for subsea blow out preventer supporting construction load test method, institute
Stating supporting construction includes being used for the ring component of uniform load, and the edge of ring component is relatively set with 2 hangers, ring component
Bottom be provided with 4 root posts；The load test method, comprises the following steps：
S1：Uniform stressed face inspection frock and column load inspection frock are made, is prepared stress surface balancing weight and column is matched somebody with somebody
Pouring weight, goes to step S2；
S2：Each hanger for the supporting construction for carrying out load test will be needed to be connected to crane gear by connecting rope
Lower section, by supporting construction need measurement load position be connected with weighing instrument, the inspection man's load of uniform stressed face is connected to branch
The top of support structure ring component, goes to step S3；
S3：Stress surface balancing weight is connected to the uniform stressed face inspection man side of holding by connecting rope, support is tied
The bottom of every root post of structure is fixed with column load inspection frock, matches somebody with somebody in the bottom vertical columns of column load inspection frock
Pouring weight, goes to step S4；
S4：Elevator, reads the reading of weighing of weighing instrument in lifting process, the reading of weighing of instrument to be weighed reaches
After given load, the present level of crane gear is kept, the retention time is at least 5 minutes, goes to step S5；
S5：Unloading stress surface balancing weight and column counterweight block, remove column load inspection frock and the inspection of uniform stressed face
Frock, goes to step S6；
S6：All weld seams to supporting construction carry out weld inspection and dimensional measurement, judge supporting construction whether no-welding-seam
Defect and size meets required precision, if so, the load of supporting construction can reach given load；Otherwise prove supporting construction
Load be unable to reach given load, re-start load test after repairing supporting construction.
On the basis of above-mentioned technical proposal, elevator specifically includes following steps described in step S4：Rising
During heavy equipment rises, the reading of weighing of weighing instrument is read, after reading of weighing often increases once safety load, keep lifting
The height of equipment, judge supporting construction whether solderless seam defect and size meets required precision, if so, continued to lift up reseting
It is standby, re-start load test after otherwise repairing supporting construction.
On the basis of above-mentioned technical proposal, the weight of the stress surface balancing weight and column counterweight block is above safety and bears
Carry.
On the basis of above-mentioned technical proposal, given load described in step S4 is 404T, and safe bearing load is 20T, stress
The weight of face balancing weight is 420T, and the weight of column counterweight block is 36T.
On the basis of above-mentioned technical proposal, the inspection frock of uniform stressed face described in step S1 and column load inspection man
The interface width of dress is all higher than the interface width of supporting construction.
On the basis of above-mentioned technical proposal, the inspection frock of uniform stressed face described in step S1 and column load inspection man
Dress is provided with limiting plate；The inspection frock of uniform stressed face described in step S2 is connected by limiting plate with ring component；Step
Inspection frock is loaded described in S3 by limiting plate and column per root post to fix.
It is further comprising the steps of before step S2 on the basis of above-mentioned technical proposal：To needing to carry out load test
Supporting construction carries out dimension control and weld inspection；The weld inspection uses the nondestructive inspection NDT methods of inspection.
It is further comprising the steps of between step S1 and step S2 on the basis of above-mentioned technical proposal：To uniform stressed face
Inspection man puts into row flaw detection, it is ensured that surface zero defect；Opposition column load inspection man puts into row flaw detection, it is ensured that surface without
Defect；The flaw detection uses the magnetic powder inspection MT methods of inspection.
On the basis of above-mentioned technical proposal, crane gear described in step S2 is the straddle truck of 600T, step from weight
Connection rope selects steel wire rope described in rapid S2 and S3.
Compared with prior art, the advantage of the invention is that：
(1) compared with load test is carried out using special fitting device and equipment in the prior art, the present invention selects state
The general crane gear (such as straddle truck) of interior shipyard or structure building factory, the supporting construction to BOP carries out load test, significantly
Reduce experimentation cost；And the project clout that test tool of the invention can be used using manufactory makes, and ensure that
The requirement of the flatness and intensity of BOP supporting constructions, is easy to promote.
(2) weight of stress surface balancing weight of the invention and column counterweight block is higher than safe bearing load, the nothing in experimentation
The weight of stress surface balancing weight and column counterweight block need to be adjusted, conventional efficient is improve, and then shorten the construction of supporting construction
Cycle.
