McDermott finishes Otis-Delta House tieback for LLOG

McDermott has completed the installation scope associated with 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.

According to the company, 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. All engineering and project management functions were completed in McDermott’s Americas, Europe and Africa headquarters in Houston.

“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 Vice President forAmericas, 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.”
