Chouest Group Expands Decommissioning Platform with Acquisition of Champagne Energy Solutions (CES)
Houma, LA, March 19, 2026 — The Chouest Group announced the acquisition of Champagne Energy Solutions (CES), previously known as Champagne Energy & Environmental Services (CEES), a leading provider of offshore decommissioning, plug & abandonment (P&A), and environmental services in the Gulf of America.
This transaction marks the first acquisition in the Chouest Group's focused expansion into the offshore decommissioning sector, with additional strategic acquisitions expected in the near term as the company builds a fully integrated platform in this space.
CES brings a strong track record of execution in offshore decommissioning and environmental services, positioning itself as a premier provider of diving and pipeline installation and removal solutions in the region, with deep customer relationships across major operators and independents in the Gulf of America.
By integrating CES into its broader portfolio, the Chouest Group enhances its ability to deliver end-to-end decommissioning solutions, including P&A, subsea intervention, environmental compliance, marine logistics support, make safe, demolition and recycling.
This acquisition aligns with the Chouest Group's long-term vision of building a vertically integrated services platform by combining marine logistics, subsea robotics, engineering, and environmental execution under one umbrella.
"We see decommissioning as one of the most important and fastest-growing segments of the offshore energy market," said Dino Chouest, Executive Vice President of the Chouest Group. "The addition of CES allows us to offer a fully integrated solution, leveraging the diverse technical expertise and operational scale found across the entire Chouest Group. This acquisition is a natural expansion of our broader service platform, creating meaningful value for our customers."
The decommissioning and P&A market represents a multi-billion-dollar global opportunity over the next decade, with thousands of assets worldwide requiring safe and efficient retirement. The Chouest Group's entry into this sector as a domestic and international provider has been met with exceptional client feedback, as the Group leverages its scale to deliver high-value, integrated solutions globally.
CES will continue to operate with its existing leadership and team, ensuring continuity for customers and ongoing projects while benefiting from the Chouest Group's scale and capabilities.
