Abstract
The present invention relates to a marine pipelaying vessel for S-lay pipelaying an offshore pipeline and integrating one or more accessories into the pipeline, and a method for S-lay pipelaying wherein use is made of such a vessel. The vessel according to the invention comprises a hull () having a stinger end and a stinger () for guiding the launched pipeline in a curved pipeline trajectory, which stinger is pivotably connected to the hull, and an accessory handling J-lay tower () at the stinger end of the hull. The J-lay tower allows the pipeline and connected accessory to be laid in J-lay mode while connecting further pipe sections to the pipeline at least until the accessory has been lowered past below the retracted stinger. A stinger support assembly () is provided for supporting the stinger in a pipelay position, and for allowing movement of the stinger between the pipelay position and a steep downwardly pivoted retracted position by pivoting the stinger about its stinger pivot axis, wherein the stinger in the retracted position is away from the J-lay firing line.
