MULTI-ACTIVITY PIPE-LAYING VESSEL

摘要

A pipe-laying vessel has a bow, a stern and a weather deck therebetween, with a moonpool passing through the weather deck. The vessel includes an S-lay pipe deployment facility located below the weather deck, having a main firing line extending along a centreline of the vessel and a pipe assembly factory for assembling single lengths of pipe to form pipe assemblies and introduce them into the firing line for deployment from the vessel. The vessel further includes a J-lay pipe deployment facility for deploying pipe through the moonpool, the J-lay pipe deployment facility including a tower located above the moon pool and pipe handling equipment for delivering pipe assemblies from the firing line to the tower. The moonpool is located to one side of the firing line. By virtue of this configuration a relatively compact structure can be achieved whereby minimal length and width dimensions for the vessel are achievable.
