Description
Technical field
The reset side of submarine pipeline terminal when terminating laying the present invention relates to submarine pipeline more particularly to a kind of submarine pipeline
Method.Belong to ocean engineering field.
Background technique
When submarine pipeline is terminated and is laid with, need to be connect with wirerope with submarine pipeline terminal, by wirerope to seabed
Pipeline applies tension, while tension on maintaining submarine pipeline, moves forward pipe laying barge, submarine pipeline is made slowly to be placed on sea
In the design routing of bed.Then, the connection of wirerope and submarine pipeline terminal then in seabed is released, and recycles wirerope to pipe laying
On ship.But in this operating process, if submarine pipeline terminal is too close to offshore platform or other structures object, it is
Pipe laying barge is avoided to collide with offshore platform or offshore structures, pipe laying barge can deviate the design road of undersea pipe-laying
Line avoids offshore platform or offshore structures with this.Therefore, lead to that submarine pipeline terminal is made finally to deviate design routing.
In order to make the submarine pipeline terminal of offset restore to design to route, pipe laying barge can be generally moved close to submarine pipeline end
End, and one group of easy loop wheel machine mechanism is installed along ship side on pipe laying barge, and connect loop wheel machine with submarine pipeline by rigging
Get up, then, the pipeline section at submarine pipeline terminal hung into sea bed, simultaneously, it is ensured that submarine pipeline mud point be in design road
By upper, later, mobile pipe laying barge makes the pipeline section at submarine pipeline terminal be in design routing top, and by submarine pipeline terminal
The pipeline section at place is placed in sea bed design routing, then, releases the connection of rigging, and recycle on rigging to pipe laying barge.But by
Pipe laying barge is set to be in offshore platform or other structures object near its circumference, and pipe laying barge and offshore platform for a long time in the above method
Or the safe distance wretched insufficiency between offshore structures, once there are the feelings such as instantaneous maximum wind weather or windlass failure
Condition, it will there are great risk of collision, bring great security risk for offshore construction.And since pipe laying barge is anchor mooring,
Frequent cloth anchor operation around platform at sea or offshore structures is needed, to smoothly complete offshore construction；In addition, due to
Can there are a large amount of pipeline, optical cable and seafloor structure etc. on sea bed around offshore platform or offshore structures, for paving
The anchor hawser laying of pipe ship brings greatly difficult and challenge.Meanwhile additionally increasing by one group of loop wheel machine mechanism on the ship side of pipe laying barge,
The reset operation of final submarine pipeline terminal is completed with loop wheel machine mechanism, and increases cost input, also, work progress is excessively
It is cumbersome.
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 submarine pipeline termination
The repositioning method of submarine pipeline terminal when laying can not only make pipe laying barge closely close to offshore platform or offshore structure
The time of object greatly shortens, and solves the problems, such as to cause risk of collision due to special circumstances；Moreover, marine when reducing construction
The frequency of cloth anchor solves the difficulty and risk problem of cloth anchor；Meanwhile enormously simplifying and make work progress, improve construction effect
Rate.
The purpose of the present invention is implemented by the following technical solutions:
A kind of submarine pipeline terminates the repositioning method of submarine pipeline terminal when being laid with, it is characterised in that: uses following construction
Step:
Step 1: making pipe laying barge deviate the design routing of submarine pipeline, to avoid using anchor hawser transverse shifting pipe laying barge
Offshore platform；
Step 2: pipe laying barge is moved forward with anchor hawser after pipe laying barge avoids offshore platform, meanwhile, on pipe laying barge, use
The connection of the terminal of wirerope and submarine pipeline, and so that submarine pipeline is kept the tension set by wirerope；
Step 3: continuing to move along pipe laying barge with anchor hawser, and while maintaining the tension on submarine pipeline, synchronizes and release
Put wirerope；
Step 4: stopping mobile pipe laying barge, and increase seabed by wirerope after pipe laying barge passes through offshore platform completely
Tension on pipeline, until make submarine pipeline mud point be in seabed design route on；
Step 5: continue to keep the tension on submarine pipeline, meanwhile, it is slowly displaced sideways pipe laying barge using anchor hawser, until
The terminal pipeline section of submarine pipeline is completely in the top of design routing；
Step 6: the tension on slow release submarine pipeline, until the terminal pipeline section of submarine pipeline completely attaches to sea bed, and
In design routing；
Step 7: removing the connection of wirerope and submarine pipeline terminal, and wirerope is recycled on pipe laying barge.
The submarine pipeline mud point need to be always positioned at design routing on.
Evaded distance of the pipe laying barge when avoiding offshore platform or offshore structures, need to be maintained at minimum value.
Beneficial effects of the present invention: the present invention due to the adoption of the above technical scheme, can not only make pipe laying barge closely
Time close to offshore platform or offshore structures greatly shortens, and solves due to special circumstances and causes asking for risk of collision
Topic；Moreover, reducing the frequency of cloth anchor in sea when construction, solve the difficulty and risk problem of cloth anchor；Meanwhile it enormously simplifying
Make work progress, improves construction efficiency.

Specific embodiment
As shown in Fig. 1-Fig. 4, the present invention uses following construction procedure:
Step 1: making pipe laying barge 2 deviate the design routing 5 of submarine pipeline 3 using 4 transverse shifting pipe laying barge 2 of anchor hawser, using
To avoid offshore platform 1；
Step 2: pipe laying barge 2 is moved forward with anchor hawser 4 after pipe laying barge 2 avoids offshore platform 1, meanwhile, in pipe laying barge 2
On, it is connect with wirerope 6 with the terminal of submarine pipeline 3, and so that submarine pipeline 3 is kept the tension set by wirerope 6；
Step 3: continuing to move along pipe laying barge 2 with anchor hawser 4, and while maintaining the tension on submarine pipeline 3, together
Step release wirerope 6；
Step 4: stopping mobile pipe laying barge 2, and increase by wirerope 6 after pipe laying barge 2 passes through offshore platform 1 completely
Tension on submarine pipeline 3, until make submarine pipeline 3 mud point 7 be in seabed design route 5 on；
Step 5: continue to keep the tension on submarine pipeline 3, meanwhile, it is slowly displaced sideways pipe laying barge 2 using anchor hawser 4, directly
The top of design routing 5 is completely in the terminal pipeline section of submarine pipeline 3；
Step 6: the tension on slow release submarine pipeline 3, until the terminal pipeline section of submarine pipeline 3 completely attaches to sea bed,
And it is located in design routing 5；
Step 7: removing the connection of wirerope 6 and 3 terminal of submarine pipeline, and wirerope 6 is recycled on pipe laying barge 2.
Above-mentioned submarine pipeline mud point need to be always positioned at design routing on.
