Abstract

A method for laying a pipe 3 on a seabed 16 from a vessel 1, the vessel comprising a reel 4 wound with deformable rigid pipe having an initial curvature and a straightener system 25 through which the pipe is provided, the method comprising at least the following steps: a) configuring the straightener system 25 to straighten a pipe, and unwinding the pipe 3 from the reel to provide a straight portion 19 of pipe having a predetermined length LS greater than 300m; b) configuring the straightener system 25 to provide a non-straight portion of pipe 24 having a predetermined length LE; wherein the non-straight portion of pipe 24 produced during step b) comprises at least one under-straightened sub-portion of pipe 21 and at least one over-straightened sub-portion of pipe 22, 23.By adjusting the lengths, relative positions and Residual Curvatures (RC) of the under-straightened and over-straightened sub-portions of pipe 21, 22, 23 it is possible to design Residual curvature sections which will rotate by around 90 degrees when they are installed and therefore will be laid horizontally on the sea bed, including in deep water.
