Part of this RD program focuses on the development of models to quantify and optimise the OM aspects in the planning phase of wind farms. This has resulted in a software tool with which proje t developers of offshore wind farms are able to estimate the annual average OM costs. The model takes into a ount (1) the failure behaviour of turbine components in terms of failure frequencies and associated repair actions; (2) the a ess vessels and hoisting equipment; and (3) the wind and wave cli- mate at the intended location. Germanischer Lloyd Industrial Services GmbH, Business Segment Wind Energy (GL Wind) validated the software as a third party. As GL Wind has realised tha
