The complex for laying of underwater pipelines is offered. The complex is intended for manufacture of different assignment pipelines on a sea bottom. The welding of pipelines is produced by the J-technique.

On a pipe-laying vessel are posed the adjusting crane, box with intended for welding tubes. The welding device, incorporating the laser, or only welding head, is posed inside a pipeline near to its end. The welding device has positive buoyancy.

Using of the offered complex will allow to realize laying of underwater pipelines with high efficiency and with sufficient quality.
