pipe laying vessel, j-lay system operable to be mounted on a vessel, and method for laying a pipe from a pipe laying vessel

摘要

A pipeline laying vessel includes a J-lay system which defines a firing line. The J-lay system includes at least one lowering device for lowering a pipe section or pipeline in the firing line from an upper position to a lower position. The vessel further includes a first pipe-moving device and a second pipe-moving device, where the first pipe-moving device is configured for moving a pipe section from a first remote position remote from the firing line to a firing line position in the firing line, and the second pipe-moving device is configured for moving a pipe section from a second remote position remote from the firing line to the firing line position in the firing line. A method for laying a pipeline uses the above mentioned pipeline laying vessel.
