Related solution: “Honeymooring® halves the cost of mooring floating wind farms” — https://businessnorway.com/solutions/semar-honeymooring-halves-the-cost-of-mooring-floating-wind-farms. Published 29 June 2022; updated 30 Sep 2026. The solution is marked under development, with Semar seeking a commercial project partner. Honeymooring connects floating wind turbines through shared mooring elements arranged like a honeycomb. It replaces heavy chains and clump weights with lighter fibre ropes and submerged buoys, uses fewer seabed anchors, and reduces peak structural loads. Semar estimates savings of about 20% for a single-floater pilot and near 50% for a grid of five or six turbines; it also claims 99% less seabed erosion. The page says simpler installation can reduce operating costs and avoid chain-tensioning work. Qualification is ongoing, some patents are granted and others pending, and Semar was seeking partners for a pilot at Norway’s METCentre. The article gives 2030 as its expected commercial deployment horizon. Listed SDG links: Affordable and clean energy; Decent work and economic growth; Life below water.
