Abstract
A reelable pipeline includes a pipe-in-pipe section and a single pipe section coupled to the pipe-in-pipe section. The single pipe section has a bending stiffness that is different from the bending stiffness of the pipe-in-pipe section. The reelable pipeline includes a transition piece connected between the pipe-in-pipe section and the single pipe section and having a bending stiffness that varies along its length.
