Plant producing coiled rigid tubing for ship-laid sub-sea hydrocarbon pipeline, includes intermediate plastic deformation- and coiling equipment on float

摘要

Intermediate deformation and winding apparatus (11) are provided at the different pipe laying barge of the first float (10). The equipment makes the rigid pipe (28) of plastic deformation, is wound up into the intermediate reel (11), is forming rigid tubular tobacco pipe (28). Float is connected to unit (16) of the bridge to component (18), which includes middle reel. Its diameter of cylinder is more than around the above pipe laying barge (42). The diameter intermediate winding drum (11) of roller is more than that last section rigid pipe can be around the pipe laying barge of upper holder. The tube assembly device is mounted on the second float (12), and the length is 40-120 m. The bridge is hinged in every one end, to allow the movement of vertical float. The connection is dismountable. The bridge is a kind of latticework. Rotating mounting member is detailed. Ballast is wound up into float according to the pipe of the quantity. First float is barge or stable Ship Structure. Method including corresponding independent claims makes to roll rigid conduit placement,With from ship.
