Shell Offshore has awarded Audubon Engineering Company a contract to provide brownfield engineering and procurement (EP) services for its Mars Corridor in the US Gulf of Mexico (GOM).

Under the three-year contract, Audubon Engineering will provide EP services for Shell’s offshore assets including the Mars, Olympus , URSA , and Vito tension leg platforms.

The water depths for this portfolio range from nearly 3,000 to 4,000 feet.

Audubon Engineering’s scope of work includes topside engineering and procurement services, as well as single-well subsea tiebacks, gas-lift installation, crane, lifeboat and HVAC replacements, controls, firewater systems and utility upgrades, and prefabricated skid packages.

The contract includes two one-year options to extend it.

Audubon plans to execute the contract through its operating centers in New Orleans, Louisiana, and Houston, Texas.

Audubon Engineering Company president Ryan Hanemann said: “We’re delighted that Shell has selected Audubon to be its contractor for these assets. We are committed to driving value and efficiency for Shell to further enhance and extend productivity across its assets in the Mars Corridor.

“Audubon is proud of our accomplishments in the GOM region, and this contract award further positions our business for growth and continued delivery in the area.”

Last month, Shell Offshore selected Worley for three years of engineering and procurement (EP) services to support five of its assets in the Gulf of Mexico (GOM).

Worley is responsible for providing professional services in digital enablement, engineering, procurement and support fabrication, and construction.

The firm’s offices in Metairie, Louisiana, and Houston, Texas, along with its engineering teams in India, will execute the services.
