APPLYING J-CURVE TECHNIQUES FOR DEEP WATER PIPELINES
The paper deals with pipelaying techniques in the Vermillion and Eugene Island areas, offshore Louisiana. As part of the planned offshore installation of the respective 12 inches oil and gas pipelines connecting the Auger Tension Leg Platform (TLP) to two shallow water platforms, Shell Oil Company required the use of J-Lay pipelaying techniques for the installation of the Phase II deepwater portions of the Auger pipelines ranging from water depths of 1200 to 2860 feet. The paper describes the J-Lay Pipelay system utilized to install the deepwater portions of the Auger 12 inch pipelines and the means by which pre-fabricated pipe joints were assembled, handled, and installed utilizing J-Lay methods and techniques. As evidenced by the successful installation of the Auger pipelines, this new technology provides proven, reliable methods in which deepwater pipelaying operations can be performed beyond the limits of conventionally moored S-Lay Reel-Lay pipelaying vessels.
