Creating a template for how deepwater work gets done
Nearly two kilometers beneath the Gulf of Mexico, where cold and pressure demand the highest precision, Subsea7 has secured a contract worth up to $150 million to bring the String Music field into productive connection with an existing deepwater hub. The agreement with Murphy Exploration is not merely a transaction between companies — it is a wager on a standardized way of working, one that its architects hope will redefine how the industry approaches the slow, costly, and consequential work of deepwater development. In the long human effort to draw energy from the ocean floor, this project in Mississippi Canyon 431 is being designed to serve as both a milestone and a method.
- A contract valued between $50 and $150 million has been awarded to Subsea7, signaling sustained industry confidence in Gulf of Mexico deepwater infrastructure despite the inherent risks and costs of operating at 1,850 meters depth.
- The project demands full-lifecycle execution — engineering, procurement, construction, and installation — in one of the most technically unforgiving environments on Earth, where a single miscalculation can cascade into costly failure.
- Engineering teams in Houston have already begun work, racing to finalize technical specifications and logistics before offshore operations are scheduled to commence in 2027.
- Subsea7 is deploying a standardized delivery model intended to make timelines more predictable and cost overruns less likely — a direct answer to an industry long plagued by both.
- The String Music field connection to the Delta House complex is being deliberately framed as a replicable template, with success here potentially reshaping how future deepwater projects across the Gulf basin are conceived and executed.
Subsea7 has won a contract from Murphy Exploration & Production Company to develop the String Music field in the Gulf of Mexico, with the deal valued between $50 million and $150 million. The scope is expansive: Subsea7 will engineer, procure, construct, and install a production pipeline, then build out the subsea infrastructure needed to connect String Music to the Delta House complex in Mississippi Canyon 431 — an existing production hub sitting nearly two kilometers below the surface.
Work has already begun at Subsea7's Houston facilities, where project management and engineering teams are establishing technical specifications and logistics. The offshore phase — the heavy construction and installation at depth — is scheduled for 2027, leaving roughly a year to finalize designs and ready equipment for conditions where pressure and cold leave no margin for error.
Craig Broussard, senior vice president of Subsea7's U.S. division, pointed to the company's standardized delivery model as central to the win — a repeatable framework designed to make projects more predictable and faster to execute in an industry where delays and overruns can quickly erode both margins and trust.
More than a single field development, the String Music project is being positioned as a proof of concept. If the methodology succeeds in reducing response times and enabling safe, seamless integration into the existing subsea network, it becomes a template applicable to future Gulf basin developments. The contract, in that sense, carries ambitions well beyond Mississippi Canyon 431.
Subsea7, the international subsea services corporation, has landed a substantial contract from Murphy Exploration & Production Company to develop the String Music field in the Gulf of Mexico. The deal, valued somewhere between $50 million and $150 million, represents a significant win for the Houston-based operator and underscores the continued appetite for deepwater infrastructure work in the region.
The project's scope is considerable. Subsea7 will handle the full lifecycle of development: engineering the system, procuring materials, constructing the necessary components, and installing a production pipeline in one of the world's most challenging environments. Beyond the pipeline itself, the company will build out the subsea infrastructure needed to tie the String Music field into the Delta House complex, an existing production hub situated in Mississippi Canyon 431 at a depth of 1,850 meters—nearly two kilometers below the surface where pressure and cold create conditions that demand precision engineering and proven expertise.
The work is already underway in some form. Project management and engineering activities have commenced at Subsea7's facilities in Houston, where teams are laying out the technical specifications and logistics for what comes next. The actual offshore operations—the heavy lifting of construction and installation at depth—are scheduled to begin in 2027, giving the company roughly a year to finalize designs and prepare equipment.
Craig Broussard, senior vice president of Subsea7's U.S. division, framed the contract win as validation of the company's collaborative approach with Murphy. He emphasized that Subsea7 has developed what he called a standardized delivery model, a repeatable framework designed to make projects more predictable and faster to execute. This matters in an industry where cost overruns and schedule delays can quickly erode margins and strain relationships.
The String Music development is being positioned as a test case for that methodology. By optimizing how the field connects to Delta House and integrating it smoothly into the existing subsea network, Subsea7 and Murphy are essentially creating a template. If the approach works—if it reduces response times and ensures safe, reliable integration—it becomes a model that could be applied to future projects across the Gulf basin. In an industry constantly searching for ways to improve efficiency without sacrificing safety or quality, that kind of standardization is valuable. The contract, then, is not just about one field in one canyon. It's about establishing a way of working that could shape how deepwater development happens in the region for years to come.

This award reflects the strength of our collaborative approach with the operator, and demonstrates our standardized delivery model that increases predictability and accelerates project execution.— Craig Broussard, senior vice president, Subsea7 U.S. division
The Hearth Conversation Another angle on the story
Why does a contract for subsea infrastructure in the Gulf matter beyond the companies involved?
Because the Gulf is where American offshore energy still happens at scale. Every major project either succeeds or stumbles in ways that influence how the next one gets built. This one is being designed as a template.
What makes the depth—1,850 meters—significant?
At that depth, you're working in near-total darkness under crushing pressure. Every component has to be engineered to tolerances that don't forgive mistakes. It's not just deeper; it's categorically harder.
The contract value is a range, $50 to $150 million. Why so wide?
Deepwater contracts often have variable scopes. The final number depends on what gets added, what gets changed, how long unforeseen problems take to solve. The range reflects real uncertainty.
What's the significance of the "standardized delivery model" Broussard mentioned?
It's Subsea7 saying: we've figured out how to do this repeatably. Not every project is a one-off nightmare. If that's true, it makes future projects cheaper and faster. That's the real win.
Why does connecting String Music to Delta House matter?
Delta House is already producing. String Music is new. Tying them together means String Music can use existing infrastructure instead of building everything from scratch. That saves money and time, but the connection has to be flawless.
