TotalEnergies has selected the Norwegian Semar Honeymooring solution for its floating offshore wind projects.
The solution aims to reduce floating wind costs and seabed footprint with its honeycomb design.
It is also expected to reduce the development costs of TotalEnergies future offshore wind projects in Norway and worldwide.
Floating offshore wind turbines have removed the depth constraints but raised the challenge of cost-effective, reliable mooring.
The design is based on the traditional technologies from mooring of oil & gas floating structures.
The innovation of the Honeymooring technology is to connect floating wind turbines in a honeycomb network and enables new ways of applying well-proven mooring technology in new and more effective anchor-sharing configuration.
TotalEnergies believes Semar Honeymooring solution can meet this challenge by reducing the carbon footprint and impact on the seabed, and lower costs by reducing peak loads of the mooring system.
It will also make marine operations more efficient and less costly, partly due to lower pre-tension and line weight in the mooring system, and opening the possibility of using smaller, less expensive vessels for marine operations, TotalEnergies added.
TotalEnergies vice president for offshore wind Olivier Terneaud said: “Thanks to our longstanding experience in the offshore oil & gas industry, we know mooring systems very well, and as we today have a large portfolio of offshore wind projects, we are proud to partner with Semar in the development of the innovative Honeymooring solution, which will contribute to lower the cost and the environmental impact of offshore wind energy.”
Semar chief executive Thor Valsø-Jørgensen said: “We are proud to have TotalEnergies as one of the important partners and contributors in the development of the Honeymooring solution.
“The overall project is being lifted by their support and the high-quality expertise which contribute to keep all of us in the forefront of the transformation towards green energy for the future.”
