Pipelaying vessel (PLV) or pipelay vessel is a specialized floating facility for submerged pipeline laying. It is widely used in offshore fields development for laying pipelines up to 1,420 millimeters in diameter down to 2,500 meters depth.

As a rule, several vessels participate in the process of pipe laying. Special barges continuously supply pipes to a pipelaying vessel, which is preceded by a vessel monitoring the seabed. The supplied pipes are unloaded on storage sites located directly on the deck of the pipelaying vessel. They should have a stock of pipes for 12 hours of work.
