Subsea 7 S.A. has signed a strategic collaboration agreement with PETRONAS Suriname E&P B.V. and the Subsea Integration Alliance to support offshore field developments in Suriname.
The agreement sets a long-term framework for early contractor involvement. Under this structure, the Subsea Integration Alliance, a joint venture between Subsea7 and SLB OneSubsea, will support multiple projects from early design to execution.
The companies said the framework is intended to speed up delivery, lower lifecycle costs, simplify procurement, reduce execution risk, and improve schedule certainty across a portfolio of offshore prospects.
Under the agreement, the Subsea Integration Alliance will provide services covering pre-FEED, FEED, and full engineering, procurement, construction, installation, and commissioning. The scope includes subsea umbilicals, risers, and flowlines from Subsea7, together with subsea production systems supplied by SLB OneSubsea.
Early engagement is a central part of the model. The companies said earlier alignment on technical design and procurement decisions can help shorten development timelines and reduce late-stage changes that affect vessel schedules, fabrication yard planning, and heavy-lift logistics.
The agreement also points to a more integrated offshore contracting structure, bringing engineering, procurement, and installation together within one alliance. This is intended to reduce interface risk, which is a frequent source of delays and cost overruns in complex subsea developments.
For offshore transport and installation activity, the model may support more predictable demand for installation vessels and subsea equipment movements, while reducing last-minute chartering and demurrage exposure. It may also reduce handovers between contractors through more centralized planning.
The agreement comes as offshore activity in the Guyana-Suriname region continues to advance following a series of discoveries. As projects move toward development, demand is expected to rise for subsea infrastructure, specialized vessels, fabrication capacity, and port support for deepwater installation campaigns.
Craig Broussard, Senior Vice President at Subsea7, said the partnership is intended to establish sustainable foundations in Suriname and support long-term regional growth. Olivier Blaringhem, CEO of the Subsea Integration Alliance, said the combined capabilities of Subsea7 and SLB OneSubsea are aimed at maximizing value as deepwater developments progress.
The companies did not disclose the timeline or size of individual projects under the framework. The agreement, however, sets the Subsea Integration Alliance as a delivery partner for PETRONAS Suriname E&P B.V. as the company advances its offshore portfolio.
