‘First ever’ hardware ordered for historic ultra-high pressure development off Louisiana coast


Schlumberger’s OneSubsea has ordered “the first-ever” 20,000 psi-rated subsea hydraulic junction plates and associated connection hardware from Oceaneering, for deployment at Chevron’s Anchor development in the U.S. Gulf of Mexico.

As Offshore Engineer reports, the hardware is destined for the first-ever 20,000 psi-rated fields to be developed in the Gulf of Mexico. The development is located on Green Canyon block 807, about 140 miles off the coast of Louisiana.

The $5.7 billion deepwater project was the first ultra-high pressure development to reach a final investment decision.

Oceaneering will oversee the design, engineering, and production of the hydraulic connection hardware along with integrated flying lead assemblies and installation equipment. OneSubsea won a contract from Chevron in 2019 to provide an integrated subsea production and multiphase boosting system for the project.

Chevron has said it will develop the first phase as a seven-well subsea development tied to a semisubmersible floating production unit (FPU) with planned design capacity of 75,000 barrels of crude oil and 28 million cubic feet of natural gas per day.

The Anchor field sits in water approximately 5,000 feet deep and is believed to hold more than 440 million barrels of potentially recoverable oil-equivalent resources.
