Floating offshore wind turbines have removed the depth constraints but raised the challenge of cost-effective, reliable mooring. Mooring 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,
• Reducing the cost of the mooring hardware and floating wind turbine structure by reducing peak loads of the mooring system,
• Making 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.
“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,” said Olivier Terneaud, VP Offshore Wind at TotalEnergies.
“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,” said Thor Valsø-Jørgensen, CEO of Semar.
TotalEnergies and R&D in Norway
TotalEnergies, with the support of its R&D Center in Stavanger, has for many years fostered highly efficient partnerships with industrial consortiums, research institutes and universities, and invests in an extensive portfolio of research and development activities in Norway. This will enable the Company to strengthen its experience and expertise in offshore wind technologies and accelerate the deployment of the industry to make wind power cheaper, more efficient, and more sustainable. In Norway, TotalEnergies has joined forces with Norsk Havvind and Iberdrola to respond to the 4.5 GW Utsira Nord and Southern North Sea II tenders and is committed to develop Norway’s offshore wind potential.
TotalEnergies and offshore wind
TotalEnergies is already developing a portfolio of offshore wind projects with a total capacity of more than 6 gigawatts, of which 2/3 are bottom-fixed and 1/3 are floating. These projects are located in the United Kingdom (Seagreen project, Outer Dowsing, Erebus), South Korea (Bada project), Taiwan (Yunlin project), and France (Eolmed project). The Company will participate in competitive tenders in the US, UK, France and Norway.
