ExxonMobil chose Oceaneering International Inc. to supply production control umbilicals for its US$4 billion Julia development in the Gulf of Mexico.
The order is for an electro-hydraulic, steel tube umbilical approximately 14 miles (22.5 km) in length. Product manufacturing will be performed at Oceaneering’s facility in Panama City, Florida, with delivery scheduled for early 2015.
The umbilical will be used to supply hydraulic control fluids, chemicals, and electrical power signals to operate and monitor the subsea wells and manifold used in the field. The water depth at the installation location is approximately 7200ft.
On Monday (July 1), Houston-based McDermott announced it has also won a contract for Julia. McDermott will undertake engineering, procurement and construction of the jumpers, four suction piles associated with the manifold, subsea pump, pump transformer and Subsea Distribution Unit /Umbilical Termination Assembly, as well as the transportation and installation of the manifold, suction piles, flying leads, subsea pump system, the power and control umbilicals and SDU/UTAs. The company will also carry out testing of the tie-back system and mechanical completion before hand over to the customer.
In June, Exxon awarded Technip a contract for Julia's project management, engineering, fabrication, installation and pre-commissioning of more than 48 km of 10.75-inch outer diameter insulated flowlines, steel catenary risers and flowline end terminations.
Discovered in 2007, the Julia field is located in Walker Ridge area of the Gulf of Mexico; it is estimated to contain about six billion barrels of resource in place. The initial development phase will be designed to produce 34,000 bo/d.
The Julia Phase I project is a subsea tie-back to a semisubmersible floating production unit and the scope includes six subsea wells, one six-slot manifold, two umbilicals, six jumpers, two flowlines with two steel catenary risers, two subsea pump modules and topsides support equipment. Production will flow through two 10-inch production flowlines with subsea single-phase boost pumps.
Exxon projects drilling operations to begin in 2014 and first oil to follow in 2016. Exxon holds 50% interest in the Julia field. Statoil holds the remaining 50%.
