Abstract
A field joint transfer system for transferring a hot field joint along a curved path between a tensioner and a stinger during deployment of a pipeline from a pipelay vessel. The system comprises a plurality of adjustable pipe support units defining a curved path between the tensioner and the stinger, wherein one or more of the pipe support units can be moved out of engagement with the pipeline to allow the hot fieldjoint to pass the respective pipe support unit without contact, while maintaining support for the pipeline along the curved path. A mobile pipe support may be provided on an overhead gantry to follow the pipe as it passes along the curved path.
