Subsea7 has secured a new subsea contract from Murphy Exploration & Production Company for the String Music development in the U.S. Gulf.

The contract is valued between $50 million and $150 million. Project management and engineering work will begin immediately at Subsea7’s Houston office in Texas, with offshore operations scheduled for 2027.

The scope covers engineering, procurement, construction and offshore installation of a production flowline and related subsea infrastructure. The system will be tied back to the Delta House development in Mississippi Canyon 431, where water depths reach up to 1,850 m.

Craig Broussard, Senior Vice President of Subsea7 U.S., said the award reflects the company’s collaborative approach with Murphy Exploration & Production Company. He said the partners are developing a more standardized and efficient delivery model to improve predictability and help accelerate project execution across the company’s developments, including the String Music fields in the U.S. Gulf.

The award follows another recent U.S. Gulf contract for Subsea7 at the Buckskin South expansion project. That scope covered the transportation and installation of a subsea umbilical and rigid flowline in water depths of up to 2,100 m.

Subsea7 was also recently selected by Vår Energi for work linked to a gas export project in the Barents Sea.
