McDermott International 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 up to 4420 ft.
The work consisted of project management, engineering and installation of 70 000 ft of insulated rigid flowline and insulated steel catenary riser as well as a control umbilical, PLEM jumper and associated flying leads.
“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,” commented Scott Munro, McDermott Vice President 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.”
