Abstract
A method of submarine pipeline starting is carried out using jacket spud leg and is laid with, with following laying step: one: by operation ship close to jacket；Two: by several wirerope wherein one with submarine pipeline starting end socket connect, then, then by submarine pipeline starting end socket lean out stinger, and make submarine pipeline originate end socket be placed in water；Three: being lauched by diver, remove barriers object；Four: being laid with operation using the starting that jacket spud leg carries out submarine pipeline as anchor point；Five: the connection between several wirerope is completed by diver；Six: moving forward operation ship, submarine pipeline is gradually entered in water by stinger, and final submarine pipeline, which is refined, to be laid on sea bed.The present invention is using jacket as anchor point, under the assistance of diver, the starting end socket of submarine pipeline is linked together with jacket spud leg, the starting for being just able to carry out submarine pipeline is laid with operation, and submarine pipeline starting can not be carried out with starting cable by, which solving the problems, such as, is laid with operation.
Description
Technical field
It is laid with the present invention relates to the starting of submarine pipeline more particularly to a kind of carries out submarine pipeline using jacket spud leg
The method for beginning to be laid with.Belong to ocean engineering field.
Background technique
Currently, when the starting that shallow waters carry out submarine pipeline is laid with operation, in general, using throw the method for beginning anchor into
Row.But due to it sometimes appear that due to submarine pipeline starting point too close to jacket the case where, causing cannot
Operation is laid with using the starting that the method for throwing beginning anchor carries out submarine pipeline；And starting has been stopped due to there is also jacket
The case where laying routing of anchor, therefore, the starting for leading to not carry out submarine pipeline using the method for throwing beginning anchor is laid with work
Industry.
Summary of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above of the existing technology, and provide a kind of using jacket pile
Leg carries out the method that submarine pipeline starting is laid with, using jacket as anchor point, under the assistance of diver, by submarine pipeline
Starting end socket link together with jacket spud leg, be just able to carry out submarine pipeline starting be laid with operation, solve nothing
Method carries out the problem of submarine pipeline starting is laid with operation with starting cable.
The purpose of the present invention is implemented by the following technical solutions:
A method of submarine pipeline starting is carried out using jacket spud leg and is laid with, it is characterised in that: uses following laying
Step:
Step 1: by construction operation ship close to jacket；
Step 2: in advance on construction operation ship, several wirerope are hung to scene, and by wherein the one of several wirerope
Root is connect with submarine pipeline starting end socket, then, then submarine pipeline is originated end socket and leans out stinger, and originates submarine pipeline
End socket is placed in water；
Step 3: being lauched by diver, jacket spud leg periphery is felt, and the object that removes barriers；
Step 4: by diver, suspender belt is wrapped in the bottom of jacket spud leg, also, by suspender belt and several wherein two
The connection of root wirerope；Operation is laid with using the starting that jacket spud leg carries out submarine pipeline as anchor point；
Step 5: being moved to construction operation quarter by diver, under the assistance of loop wheel machine, several steel are completed by snap ring
Connection between cord；
Step 6: move forward construction operation ship after returning to construction operation ship by diver, with construction operation ship to
Preceding movement, submarine pipeline are gradually entered in water by stinger, and final submarine pipeline, which is refined, to be laid on sea bed.
Beneficial effects of the present invention: the present invention is due to the adoption of the above technical scheme, easy to operate, using jacket as fixed
The starting end socket of submarine pipeline is linked together with jacket spud leg under the assistance of diver, is just able to carry out sea by site
The starting of bottom pipeline is laid with operation, and submarine pipeline starting can not be carried out with starting cable by, which solving the problems, such as, is laid with operation.

Specific embodiment
As shown in Fig. 1-Fig. 7, the present invention uses following laying step:
Step 1: by construction operation ship 1 close to jacket 3；
Step 2: as shown in Figure 1, in advance on construction operation ship 1, by loop wheel machine 2 by the first wirerope 6, the second wirerope 7
And third wirerope 8 is hung to scene, and third wirerope 8 is connect with submarine pipeline starting end socket 10, then, then by seabed
Pipeline starting end socket 10 leans out stinger 3, and makes submarine pipeline starting envelope 10 to be placed in water；
Step 3: being lauched by diver 4,5 periphery of jacket spud leg is felt, and the object that removes barriers；
Step 4: shown in Fig. 7, by diver 4, suspender belt 11 is wrapped in the bottom of jacket spud leg 5 such as Fig. 3, Fig. 5, and
And by snap ring 9, suspender belt 11 is connect with the first wirerope 6 and the second wirerope 7；Using jacket spud leg as anchoring
The starting that point carries out submarine pipeline is laid with operation；
Step 5: shown in Fig. 6,1 tail portion of construction operation ship is moved to by diver 4 such as Fig. 2, under the assistance of loop wheel machine 2,
The first wirerope 6 is completed by snap ring 9, the connection between the second wirerope 7 and third wirerope 8；
Step 6: construction operation ship 1 is moved forward, with construction operation ship 1 after returning to construction operation ship 1 by diver 4
Forward movement, submarine pipeline 12 by stinger 3 gradually enter water in, final submarine pipeline 12, which is refined, is laid on sea bed
On.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
