Technip has been awarded a lump sum contract by Deep Gulf Energy II, LLC for the development of the Odd Job field. This ultra deepwater field is located in Mississippi Canyon, offshore New Orleans, in the Gulf of Mexico, in water depths ranging from 1,330 to 1,825 meters.
The contract consists of:
Project management and engineering services,
Fabrication and installation of approximately 23 kilometers of pipe-in-pipe flowline,
Fabrication and installation of approximately 2 kilometers of Steel Catenary Riser (SCR),
Design, fabrication and installation of in-line sled, flowline end termination ,
Fabrication of jumper,
Pre-commissioning for the flowline and SCR system.
This new award highlights our unique vertical integration in the subsea business environment, covering all aspects of this field development from engineering to design, manufacturing and installation.
Technip’s operating center in Houston, Texas, USA, will manage the overall project. The SCR and flowline system will be fabricated at the Group’s spoolbase in Mobile, Alabama, USA. The offshore installation is expected to be performed in the summer of 2016 by Technip’s vessel the Deep Blue, one of the world’s largest ultra-deepwater pipelay and subsea construction vessel.
Deanna Goodwin, President of Technip in North America commented: “Technip is delighted to continue its strong long-lasting relationship with Deep Gulf Energy and to bring and share its unique experience to this new project.”
Fast facts about subsea products:
– Pipe-in-pipe flowline: steel pipes assembly consisting of a standard production pipe surrounded by a so-called carrier pipe. The gap between the carrier and production pipes is filled with an insulation material.
– Flowline: a pipe, laid on the seabed, which allows the transportation of oil/gas production or injection of fluids. Its length can vary from a few hundred meters to several kilometers.
– Jumper: a short section of pipe for the connection of two subsea structures.
– Riser: a pipe or assembly of pipes used to transfer produced fluids from the seabed to the surface facilities or to transfer injection fluids, control fluids or lift gas from the surface facilities and the seabed.
– Flowline end termination: a subsea structure which connects rigid flowline and flexible riser.
