McDermott Completes Otis Subsea Tieback for LLOG

McDermott International has completed the deepwater subsea tieback from the Otis well to the Delta House floating production system in the Gulf of Mexico.

McDermott’s Lay Vessel North Ocean 105 (LV 105) completed the work, on behalf of LLOG Exploration Offshore, in Mississippi Canyon 79 in water depths ranging from 3,861 feet to 4,420 feet.

The scope of work consisted of project management, engineering, and installation of 70,000 feet of insulated rigid flowline and insulated steel catenary riser as well as a control umbilical, PLEM jumper and associated flying leads. The flowline and riser were fabricated at McDermott’s new spoolbase and marine facility in Gulfport, Mississippi.

“This marks an important milestone for the McDermott organization as the first project executed in its Gulfport Spoolbase and the first installation of a steel catenary riser by the LV 105,” said Scott Munro, McDermott VP for Americas, Europe and Africa.

“The execution of the Otis project has positioned McDermott for success on our other 2016 reel lay projects, including Anadarko Caesar Tonga Phase II. This project demonstrates our commitment to adding value to the subsea tieback market and is the foundation for McDermott to establish itself as the reel lay contractor of choice for our customers in the Gulf of Mexico.”
