Acteon provides specialist support for the design, construction and installation of floating renewable energy projects.
Floating wind developments tend to be large and often complex projects that present significant technical challenges. Early involvement for all the project participants makes it easier to explore the available options and select the most efficient one.
At Acteon, we provide insights across areas such as anchoring, cable laying, installation methods, the mitigation of technical risks and lowering the levellised cost of energy (LCoE). Customers benefit from our pre-front-end engineering design and desktop studies; accurate evaluations of seabed characteristics; floating hull assessments; and advice in areas such as high-level mooring and cable arrangements, installation considerations and preliminary scheduling.


Our focus is always on finding innovative ways to reduce project footprints and overall costs.
This is possible through our profound, cross-disciplinary understanding and execution of design and engineering interactions across the project life cycle.

Our geophysical and geotechnical survey data teams work closely with our mooring experts to design floating wind foundations and anchors most efficient for the seabed conditions.

We have extensive experience of handling large assets, large volumes of mooring equipment and long cable lengths. This is invaluable when dealing with larger floating wind turbines.

We deliver innovative and effective mooring and asset integrity systems for floating wind energy projects worldwide.
7 Challenges of Floating Wind
Cost and risk unpredictability
Cost and risk unpredictability
One challenge of installing floating wind farms will be to scale up projects from single to multiple units and still control costs. Contractors and offshore personnel need to have considerable experience in dealing with complex logistics and supply chain, towing large floating assets and performing multiple projects simultaneously.

Supply chain and logistics
Supply chain and logistics
A 50-turbine floating wind farm could use 150 to 200 anchors and hundreds of kms of chain and fibre rope. Sourcing as well as storing and shipping such large volumes of equipment requires very specific knowledge and experience. While this could be a big strain on the supply chain, this challenge can be overcome by early design and early engagement. Established procurement agreements, a known supply chain, and a large mooring equipment inventory are a clear advantage.

Maintenance
Maintenance
A proactive approach to monitoring and maintaining these structures through live data gathering systems incorporated throughout the life of the asset, along with engineered maintenance schedules, enable timely and informed integrity management decisions.

Variability
Variability
Over 80 floating wind hull designs exist and conditions can be different from one area of the farm to another. Mooring engineers need to combine several variables to deliver an optimised design, from soil sample interpretation, metocean conditions, and environmental concerns, to dynamic cable constraints, supply chain availability, installation vessel availability and mooring loads.

Cable safety
Cable safety
Coupled analysis of the floating wind platforms, accounting for both hydrodynamic and aerodynamic loading, ensures the array cable layouts be safely optimized and specifically engineered to withstand dynamic loads from harsh offshore environmental conditions.

Structural integrity
Structural integrity
Ensuring the structural integrity of the floaters increases the lifetime of the assets, a key element in decreasing the LCOE (levelised cost of energy). It is important to define the perceived operational risk and required analytics before specifying and deploying the sensors. Digital twins are valuable tools to maintain the structural integrity of these structures.

Challenging soil conditions
Challenging soil conditions
New areas identified as suitable for floating wind exhibit challenging soil conditions such as a rocky seabed or variable soil structure. Experience with all anchor types such as drilled and grouted anchors, driven piles, plate anchors and drag anchors as well as shared mooring options are necessary to deliver economic, safe and environmentally low-impact solutions.

Acteon solution:
Designing a mooring system for a floating energy production system is complex and must encompass other factors than just metocean, soil and logistical elements. Turbine proximity for example to other turbines must be accounted for, as it affects energy production efficiency. The system’s interaction with other marine users and marine life must also be evaluated. Our engineers provide full support from conceptual engineering to detailed system design and installation procedures.
Proof points
- Our engineers can perform coupled analysis of floating wind platforms, accounting for both hydrodynamic and aerodynamic loading, to provide complex projects with an optimised design.
- Our engineering team has expert knowledge and experience in the design and installation of all anchor types and can help you decide what anchor type would be best for your application.
