Harness the potential of the world's offshore energy resources

We act on energy

Offshore energy projects are getting bigger, deeper and more complex - and Acteon is meeting that challenge.  

We help offshore wind developers and oil and gas operators design, install, maintain and decommission infrastructure in the world’s most demanding marine environments. 

By combining digital insight, domain-specific engineering and reliable offshore execution, we reduce risk, optimise cost and enable smarter decisions throughout the lifecycle of an asset.  

From seabed characterisation to offshore construction and late-life integrity, we turn complexity into clarity.

We act on every stage of the offshore lifecycle

Leverage our technical and engineering expertise across the lifecycle of offshore infrastructure, from seabed to surface - and act with confidence knowing we ensure maximum economic value of offshore energy assets.

Site investigation and characterisation

Understand seabed conditions and move from concept to construction with certainty. We conduct thorough surveys of offshore energy sites, unlocking the data needed to make smart decisions.

PROD (Portable, remotely operated drill)

PROD is a self‑contained, remotely operated seabed drilling and geotechnical testing system, operating in water depths to 4,000 m and investigating seabeds to 150 m. PROD has a proven global track record, including operations in ultra-deepwater, challenging soil conditions, and extreme seabed slopes. Operating directly on the seabed, PROD avoids time-consuming deployment of drill string, yielding immediate efficiency gains.

European offshore wind leaders launch Searénité Consortium to advance marine noise mitigation

Chantiers de l’Atlantique, EDF power solutions, Heerema Marine Contractors, Menck, RTE, Sealence and Smulders have formed a consortium to develop a cutting-edge noise mitigation system for offshore wind operations. The growth of offshore renewable energy presents an important opportunity to further strengthen our commitment to responsible operations. Understanding and managing underwater noise becomes increasingly essential to protecting marine ecosystems. Activities such as ship traffic, sonar use, and offshore construction can affect marine life over large distances. Offshore wind farm installation is one of these activities.
