Description
Technical field
The invention belongs to field of ocean engineering, are related to a kind of device being laid with for underwater pipeline.
Background technology
As the mankind deepen continuously to ocean development, become increasingly necessary in submarine laying transfer pipeline or circuit,
Such as the pipeline or transmission of electricity or transmission line of information cable of conveying oil gas, to ensure that the safety of transmission of electricity or transmission line of information cable generally also needs
It puts it into the pipeline being laid in advance.
The laying method of submerged pipeline is mainly at present：Ship is in place by laying-out when pipe laying and positioning of casting anchor.It is prefabricated
Pipeline section aboard ship connect after from stinger enter water in, pipe laying barge gradually moves forward by mooring system, connection one section advance
One section.This is current at present lay method.By nineteen eighty-two only in the world there are about 70 pipe laying barges, the maximum pipe laying depth of water is reachable
200m can spread the pipe of diameter 1120mm.
But the mode for aboard ship carrying out pipeline section connection is taken not only to need the equipment such as stinger, and connect pipeline
To pass through longer pendency transition obliquely to seabed from ship and get to seabed, so ship will carry pendency transition
The weight of pipeline.This section of pendency section tube body not only increases the load of ship, and be easy to cause the damage of pipeline.Ship and pipe
Body interacts, and especially when stormy waves is larger, the movement of ship acts on pipeline and is easily damaged pipeline, the movement of same pipeline
It acts on ship and is also easily damaged ship, threaten the safety of ship.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of off-shore pipeline tube body decentralization control
Control equipment, this off-shore pipeline tube body transfer the sectional pipe decentralization that control device realizes pipeline, avoid pipeline from pendency section occur, reduce
The pendency pipeline load that ship is received reduces the risk that pipeline and ship are damaged.
Object of the invention can be realized by the following technical scheme：A kind of off-shore pipeline tube body decentralization control device, packet
The workboat for construction is included, the carrier chain of transport sectional pipe is provided with from workboat to seabed, conveying link ends connect side by side
