Chouest Group Expands as Helix Exits the Shallows

Helix Energy Solutions divests its shallow water unit for $107.5 million, pivoting toward high-stakes deepwater projects and subsea robotics

5 May 2026

One $107.5 million cash transaction just redrawn the Gulf of America's well decommissioning sector. On May 1, 2026, Helix Energy Solutions closed the sale of its entire shallow-water abandonment business to C-Dive, a Chouest Group company. Signed and settled the same day, it hands one of the Gulf shelf's most established plug-and-abandonment operations to a new owner.

Strategic, not reactive, the move positions Helix ahead of a planned merger with Hornbeck Offshore Services. Combined, the two firms will form a deepwater-focused group built around high-specification vessels, subsea robotics, and advanced well intervention technology. Shallow-water plug and abandonment carries thinner margins than deepwater work, and Helix is reallocating capital accordingly.

Timing sharpens the logic. Thousands of aging wells and structures across the Gulf face mandatory permanent closure under US regulatory rules, and enforcement timelines are tightening fast. Demand for specialist abandonment contractors is climbing to match. By placing its shallow-water business with Chouest, a proven Gulf operator, Helix ensures continuity in a critical market while redirecting toward higher-value work.

For Chouest, this acquisition extends its offshore logistics and vessel expertise into structured decommissioning services at exactly the right moment.

Chief Operating Officer Scotty Sparks said the sale sharpens Helix's focus on "deepwater well intervention and decommissioning, robotics and other offshore services." Executing the Hornbeck merger will test that focus at scale.

Across the US offshore sector, consolidation is accelerating. Shallow and deepwater operators are splitting into distinct specialisms, each serving a regulatory environment that demands permanent, verifiable well closures. With Gulf decommissioning backlogs growing and federal pressure intensifying, both Helix and Chouest are now positioned to lead separate segments of a market moving in only one direction.
