Offshore wind

We offer fit-for-purpose consultancy to projects within offshore wind, as well as we develop R&D concepts that benefit the growing offshore renewables industry. Semar offere its competence and experience earned from the offshore oil & gas industry to multiple wind farm projects. The feedbacks we got so far are that the way we work, based on team collaboration and multi-discipline approach where we encourage acquisition of multi-discipline competences, were adaptable to the specific challenges and demands of the offshore renewables industry.

Honeymooring

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
