Abstract

Official abstract text for this publication.

A method of laying pipeline from a vessel ( 10 ) is disclosed. The vessel ( 10 ) includes many pipe processing stations ( 36, 42 ), arranged across the width of the vessel. In one embodiment, there are two pipe processing areas ( 38, 40 ) separated along the length of the vessel. The pipe processing stations ( 36, 42 ) may be operable in two modes of operation, for example, a first mode of operation where the vessel produces triple joint pipe strings (from three lengths of pipe section welded together) and a second mode of operation where double joint pipe strings are produced, for example, from two single length pipe sections having a significantly greater length than the single length pipe sections used in the first mode of operation. In one embodiment, a triple joint pipe section is part welded in one pipe processing area ( 38 ), then moved along the length of the vessel ( 10 ) to a different pipe processing area, where further welding operations are performed on the triple joint. In order for the vessel to operate in two modes of operation, the storage bin facilities ( 12 ) for storing single length pipe sections are configured to be able to accommodate different lengths of single length pipe section arranged end to end in a single bin.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of laying pipeline from a vessel, wherein the method comprises the following steps: a) providing a vessel having a deck on which there are arranged a multiplicity of pipe processing stations across the width of the vessel, the pipe processing stations defining at least one pipe processing area, b) simultaneously operating the pipe processing stations in a first mode of operation to form a multiplicity of jointed pipe sections extending longi…
