Abstract:
A pipe-laying apparatus and method for laying or raising a pipeline from a vessel. The apparatus includes a first pipe gripping assembly disposed on a pipe laying path along which pipeline passes during laying, a second pipe gripping assembly disposed on the 10 pipe-laying path, and a drive unit for causing relative movement in a direction along the pipe-laying path between the first pipe gripping assembly and the second pipe gripping assembly. The first pipe gripping assembly includes both a pipe gripping arrangement for gripping a pipe during pipe-laying and a cable gripping arrangement for gripping a cable during an operation when a cable is connected to a length of pipeline.
