McDermott International has completed installation scope related with the Otis development in the Gulf of Mexico on behalf of LLOG Exploration Offshore.
The company’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 3,861ft to 4,420ft.
McDermott’s scope of work involved project management, engineering, and installation of 70,000ft of insulated rigid flowline and insulated steel catenary riser in addition to a control umbilical, PLEM jumper and associated flying leads.
The flowline and riser were fabricated at the company’s new spoolbase and marine facility in Gulfport, Mississippi.
McDermott completed all engineering and project management functions in its Americas, Europe and Africa headquarters in Houston.
McDermott vice-president for Americas, Europe and Africa Scott Munro said: "This marks an important milestone for the McDermott organisation as 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."
