HOUSTON, Jan. 27, 2016 -- McDermott International, Inc. (NYSE:MDR) today announced it has been awarded a subsea umbilical and flowline installation contract by Anadarko Petroleum Corporation in support of its Phase II development of the Caesar/Tonga field located in the U.S. Gulf of Mexico.

Lay Vessel 105 and North Ocean 102 are docked to support operations at McDermott’s spoolbase facility in Gulfport, Mississippi.

Caesar/Tonga Phase II is being developed as a subsea tieback to the Anadarko-operated Constitution spar, located in Block Green Canyon 726 and 727, with the new development in approximately 5,000 feet of water. The scope covers:

• Project management;
• Engineering, fabrication and installation of two 7,700-feet-long Pipe-in-Pipe (PIP) insulated rigid flowlines terminated by pipeline end terminations (PLETs) on either end;
• Installation of one subsea manifold and associated jumpers;
• Installation of a subsea control umbilical approximately 72,000-feet long and associated flying leads; and
• Pre-commissioning.

“The combination of our Pipe-in-Pipe experience, efficiency of the Lay Vessel 105 (LV105) and our Gulfport spoolbase led McDermott to secure this important contract from Anadarko,” said Scott Munro. Vice President for Americas, Europe and Africa, McDermott. “We appreciate Anadarko’s trust in our experience and ability to deliver in the Gulf of Mexico.”

McDermott’s operating center in Houston, Texas, has commenced the overall project management and engineering. The PIP flowlines are expected to be assembled and fabricated at McDermott’s spoolbase facility in Gulfport, Mississippi. Offshore installation is expected to be completed in late 2016 by the LV105, McDermott’s deepwater rigid reel-lay vessel, and by the North Ocean 102, McDermott’s deepwater flexible lay vessel, which is expected to complete the umbilical installation and subsea construction scope of work.

The lump sum contract award will be reflected in McDermott’s fourth quarter 2015 backlog.
