Abstract
A method of dissipating heat from a circumferential girth weld when fabricating a pipeline for subsea laying comprises placing an annular or part-annular heat sink in thermal contact with an inner or outer surface of a pipe. The heat sink comprises an annular or part-annular wall and fins for dissipating heat received from the pipe through the wall. The heat sink may be integrated with a line-up clamp or with a cooling module that also comprises a blower for forcing cooling gas flow across the heat sink. Another approach is to encircle the pipe with a blower and to force cooling gas from the blower inwardly against an outer surface of the pipe.
