Cal Dive International recently completed the installation of Dominion Exploration & Production's 17 Hands and Rigel flow line system. The project included the installation subsea to subsea of 121,072 feet of 8 inch diameter pipe in water depths ranging from 3,500 to 5,883 feet from CDI's reel lay vessel Intrepid. The pipe lay operation was initiated at the 17 Hands well location in MC 299 utilizing Cal Dive's hinge over Pipeline End Termination ("PLET") system, an in-line PLET was installed at the Rigel well in MC 252 then the flowline system was terminated with a standard second end PLET at the Gemini manifold location in MC 292. The entire flow line system was hydrotested and dewatered utilizing CDI's semi-sub Uncle John and CDI's subsea commissioning system. The project was completed without incident two months ahead of schedule.
Cal Dive has recently mobilized the Uncle John to install the Jumpers at all three well locations, as well as provide early production by operating the 17 hands tree to facilitate flowing product via an IWOCS system.
