Honeymooring - a promising R&D project

Our innovative solution Honeymooring™ is a unique and cost-effective way of mooring floating wind turbines in a “honeycomb” network using, flexible lines and active sharing of anchors and buoys. Honeymooring™ is estimated to reduce mooring hardware costs considerably compared to traditional catenary mooring solutions with chains/ fiberline and clump weights.

With Honeymooring, we offer:

– Reduced CO2 emissions

– Limited seabed erosion

– Reduced CAPEX

– Reduced time to “first electron”

– Increased power production
