"IMPROVEMENTS IN OR RELATING TO WELDING PIPE LINES" Abstract of the disclosure A system for supporting pipe in the firing line on a lay barge where fresh lengths of pipe are welded to the end of the pipe string includes a number of trolleys. The trolleys support the pipe at intervals along its length and at a sufficient distance above the deck for access completely around the pipe for welding at the joints between adjacent lengths of pipe. The trolleys move with the pipe, during a pipe launching sequence, for example on rails, so that welding can continue even during launching of pipe.
