Pipeline laying vessel for laying a pipeline on a seabed

A pipeline laying system for laying a pipeline along a firing line and from a pipeline laying vessel comprising a hull, which pipeline laying system comprises;

• a positioning device for in use positioning a pipe section in the firing line along which the pipeline is laid, which positioning device is constructed and arranged to in use be supported by the hull, and
• a clamp for in use holding the pipeline suspended from the vessel, wherein the clamp is located in the firing line, and comprises a support device constructed and arranged to allow the clamp to hold the pipeline in a first mode wherein the clamp has a fixed position relative to the positioning device, and in a second mode wherein the clamp is pivotable relative to the positioning device, and wherein
• the support device comprises a rigid support member and at least part of the clamp is in the first mode supported by the hull or the positioning device via the rigid support member.
