MCDERMOTT International has completed the installation scope for the Otis development in the Gulf of Mexico on behalf of LLOG Exploration Offshore.

McDermott’s Lay Vessel North Ocean 105 (LV 105) completed the deepwater subsea tieback from the Otis well in Mississippi Canyon 79 to the Delta House floating production system 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, pipeline end manifold jumper and associated flying leads, the company said.

The flowline and riser were fabricated at McDermott’s spoolbase and marine facility in Gulfport, Mississippi.

All engineering and project management functions were completed at McDermott’s Americas, Europe and Africa headquarters in Houston.

McDermott vice president for Americas, Europe and Africa, Scott Munro, said completion of work on Otis was an important milestone for the group as it was the first project executed in its Gulfport Spoolbase and the first installation of a steel catenary riser by the LV 105.

“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,” Mr Munro said.
