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 the expertise of our business lines Intermoor, UTEC and 2H, we deliver mooring, survey, asset integrity and offshore engineering solutions that span the entire asset lifecycle.  This integration reduces risk, optimises cost and enables smarter decisions.  

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

What influences anchor selection in offshore mooring systems?

Anchor selection is one of the most important decisions in offshore mooring design. While holding capacity is a fundamental consideration, it is only one part of a much broader engineering challenge. The selected anchor can influence mooring design, installation methodology, project economics, inspection requirements and long-term system performance.

What happens when conventional TT fatigue analysis is no longer enough?

Many ageing FPSOs are operating well beyond their original design life. As operators pursue asset life extension and continued production, understanding the true fatigue condition of critical mooring components becomes increasingly important. Traditional tension-tension (TT) fatigue assessment remains a widely used approach for mooring analysis, but what happens when TT fatigue analysis alone no longer captures the full picture?
