Subsea 7 S.A. has been awarded a subsea infrastructure contract valued between $50 million and $150 million by Murphy Exploration & Production Company. The project covers the engineering, procurement, construction, and installation of a deepwater production flowline for the String Music field in the US Gulf.
Murphy Exploration & Production Company has awarded a subsea infrastructure contract for the deepwater String Music project to Subsea 7 S.A. According to official corporate announcements, the value of this transaction is categorized as being between $50 million and $150 million. The operational scope of work mandates the engineering, procurement, construction, and offshore installation of a dedicated production flowline and related subsea systems, which will tie the new development back to the existing Delta House production facility in Mississippi Canyon block 431. Operations will occur at extreme depths reaching up to 1,850 meters.
Subsea 7 S.A. is a Luxembourg-domiciled global leader specializing in offshore energy infrastructure delivery, while Murphy Exploration & Production Company is an upstream oil and natural gas operator. Technical planning and project management are beginning immediately at the contractor's facilities in Houston, Texas, with marine installation activities slated to commence in 2027.
This infrastructure development directly impacts the offshore engineering, marine logistics, and upstream oil and gas industries within the Gulf of Mexico. By utilizing a subsea tie-back configuration to the existing Delta House hub, the operator avoids the steep capital requirements and environmental overheads of constructing standalone deepwater processing platforms.
For energy sector executives and institutional investors, this award demonstrates a clear market shift toward standardized project delivery models. Operators are increasingly prioritizing collaborative, modular subsea architectures to enhance timeline predictability, mitigate execution risks, and maximize the economic lifecycle of existing offshore infrastructure assets amidst a highly competitive global energy services landscape.
