Honeymooring® by Semar
Semar’s patented Honeymooring® system is a cost-effective and environmentally friendly mooring solution for floating wind farms. Using a honeycomb-like network of shared buoys and lightweight fiber ropes, Honeymooring® eliminates the need for heavy steel chains - reducing costs, installation time, and seabed impact. The system enables scalable, low-tension mooring with fewer anchors, making floating wind more competitive and sustainable.
