Subsea 7 announced the award of two contracts, with a combined value of up to US$800 million, by ConocoPhillips Australia and by Murphy Exploration and Production for services in Australia and US Gulf of Mexico.
The first contract, by ConocoPhillips Australia Barossa worth between $300-500 million is for delivering the SURF scope for the Barossa Project. The Barossa field is located 300 km offshore Darwin in the Northern Territory of Australia.
Subsea 7’s scope of work includes project management, engineering, procurement, fabrication, transportation, installation and pre-commissioning of 36 km of flowlines and associated client-supplied risers, umbilicals and subsea structures in water depths between 230 and 270 metres. The offshore work scope is scheduled to occur in 2022 and 2023, using Subsea 7’s reel-lay and heavy construction vessels.
Meanwhile, the second contract, worth between $150-300 million by Murphy is for the subsea installation services in Green Canyon area of the Gulf of Mexico.
The services are related to the Samurai, Khaleesi, and Mormont developments tying back to the King’s Quay semi-submersible. The King’s Quay host facility is approximately 175 miles south of New Orleans.
The project scope includes engineering, procurement, construction, installation and commissioning of all subsea equipment including PLETs, PLEMs, umbilicals and distribution hardware, production and export flowlines and jumpers, as well as the wet tow in the Gulf of Mexico to the fields and mooring system installation of the semi-submersible FPS.
Project management and engineering will commence immediately at Subsea 7’s offices in Houston, Texas. Fabrication of the flowlines and risers will take place at Subsea 7’s spoolbase in Ingleside, Texas, with offshore operations occurring in 2021.
Craig Broussard, Vice President for Subsea 7 US, said, “We are honoured that Murphy has selected Subsea 7 for this key EPCI SURF and mooring project. Subsea 7 and Murphy have built a strong, collaborative working relationship over the years through the proficient execution of projects performed on budget and on schedule. This effective working relationship has set the stage for a best-in-class project delivery of one of the largest subsea development projects in the Gulf of Mexico. Subsea 7 will provide a single point contract for the SURF and mooring work scopes on this project, which allows for improved management of the interface risk.”
