During the summer of 1981, McDermott installed the second of the world's two deepest platform-to-shore pipelines - a 16 in-diam gas line running from the Cognac platform in 1020 ft of water in the Gulf of Mexico to the Louisiana coast. For the J-tube pull operations, a 12-point mooring system held the lay barge in position 3500 ft from the platform. A 400,000-lb Lucker unit hanging on the platform pulled the pipe. The lay-barge equipment included a 315-ft, five-piece stinger (held in place by tugboat), two Western Pipemaster tension machines, and nine stations for welding, X-raying, sandblasting, and coating the pipe.
