TotalEnergies has announced a partnership with Norway’s Semar to use and develop the company’s Honeymooring technology in future floating wind projects.

TotalEnergies said Monday that it had selected the Honeymooring solution, with the aim of reducing the costs and seabed footprint of floating wind projects.

It said use of the solution is expected to reduce the development costs of the supermajor’s future offshore wind projects in Norway and worldwide.

Semar describes the technology as “highly scalable and flexible” applicable for most locations. It works by connecting floating wind turbines in a “honeycomb” structure using shared anchors, specialised equipment and fibre ropes.

This enables developers to optimise the overall wind farm layout for prevailing wind directions or area restrictions. It can be used in a variety of water depths, and with a range of turbine configurations.

The company says it can reduce mooring hardware costs by more than 50% compared to traditional mooring systems with chains and clump weights.

It also simplifies the process of installation by reducing pre-tensioning by more than 80%, enabling floating turbines to be installed using smaller vessels.

Ultimately, this helps lower the overall levelised
