FIELD: pipeline transport.
SUBSTANCE: group of inventions can be used in laying underwater pipelines. Flexible pipeline comprises section "pipe in pipe" and section of single pipe connected with section "pipe in pipe". Single pipe section has bending stiffness that differs from bending stiffness of pipe-in-pipe section. Besides, flexible pipeline additionally contains transition element connected between section "pipe in pipe" and section of single pipe and having rigidity for bend, which varies along its length. Also disclosed is a method of deploying such a pipeline in sea.
EFFECT: flexible pipe is proposed.
