Abstract
Official abstract text for this publication.
The invention relates to a marine pipelaying system comprising a vessel ( 1 ) provided with a pipeline launch tower ( 6 ). The tower ( 6 ) comprises pipe laying equipment defining a tower firing line, and is adapted for launching a pipeline ( 20 ) along the firing line into the sea. The system furthermore comprises a hang off module ( 15 ) supported in the lower part of the firing line for clamping and supporting the weight of previously launched pipeline ( 20 ) as well as a stinger for guiding the launched pipeline ( 20 ). The stinger ( 10 ) is supported at its upper end in the lower part of the firing line. The stinger is displaceable from the firing line.
