McDermott wins Gulf of Mexico subsea tieback project

McDermott International Inc. has been awarded a sizeable lump sum contract by LLOG Exploration Offshore LLC (LLOG) in support of LLOG’s Otis development located in the Gulf of Mexico. The lump sum contract will be included in McDermott’s 2Q15 backlog.

Otis field, Gulf of Mexico

The Otis field, located in Block Mississippi Canyon 79, will be developed as a subsea tieback to the Delta House floating production system and lies in approximately 3800 ft of water. The contract scope includes project management, engineering, fabrication and installation of a 75 000 ft insulated rigid flowline and insulated steel catenary riser, with associated pipeline end termination and jumper, and pre-commissioning.

McDermott’s Houston office will perform the overall project management and engineering. The flowline and steel catenary riser are scheduled to be assembled and fabricated at McDermott’s new spoolbase facility in Gulfport, Mississippi.

Offshore installation is scheduled to be completed in early 2016 by McDermott deepwater rigid reel lay vessel 105 (LV 105).

Comment from McDermott

“This award represents an important step in McDermott’s growth plans for the Gulf of Mexico,” said Scott Munro, Vice President of Americas, Europe and Africa at McDermott. “This is our first contract award for rigid reel lay in the area since the delivery of the LV 105 deepwater vessel and development of our new Gulfport marine facility and spoolbase. We look forward to working with LLOG over the coming months and delivering this project safely.”
