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 5000ft of water.
The scope of the project covers: project management; engineering, fabrication and installation of two 7700ft-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 72,000ft long and associated flying leads; and pre-commissioning.
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 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, Anadarko VP for Americas, Europe and Africa.
The lump sum contract award will be reflected in McDermott’s Q4 2015 backlog.
