Innovation is booming in Norway as SEMAR AS develops a game-changing mooring solution promising to cut hardware costs significantly.

Honeymooring™ is a new and cost-effective way of mooring floating wind turbines in a network using shared buoys, synthetic fibre lines and anchors.

Semar AS’ innovative Honeymooring™ solution is estimated to reduce hardware cost with up to 50% compared to traditional mooring solutions based on steel chains.

By connecting floating wind turbines in a honeycomb layout, Honeymooring™ offers a unique way of applying well-proven mooring technology in an innovative way that challenges existing solutions.

Honeymooring Solution

Semar AS’ Honeymooring solution has so far been thoroughly assessed through a pre-project phase, identifying significant mooring-hardware cost savings compared to existing mooring solutions. These savings contribute to significantly reduce the CAPEX for wind parks consisting of several floating units. The pre-project was financially supported by Innovation Norway, Equinor, TotalEnergies and Semar.

Following the encouraging pre-study results, the Research Council of Norway financially supports the ongoing research and development (R&D) project “Honeymooring – Efficient mooring of floating wind farms”. Equinor, TotalEnergies, SINTEF Ocean and Norcable are partners in this three-year R&D project, where Semar AS develops the methodology required to analyse wind parks with shared moorings, and further matures and optimizes the Honeymooring™ design. Altogether, the R&D project has been granted significant financial support of NOK 19 million (see https://prosjektbanken.forskningsradet.no).
