A major contributor to high O&M costs is downtime caused by accessibility restrictions, as severe weather conditions offshore restrict times for technician transfer to the wind turbine platforms or completion of maintenance tasks. Existing accessibility models consider very few metocean parameters (mainly wind speed and significant wave height) for limiting accessibility. In reality, offshore wind accessibility is much more complex, and improved understanding will lead to improved use of vessels and weather windows, thereby reducing O&M costs and improving availability. Within the OM JIP project new datasets and techniques for understanding accessibility are being created and then incorporated in an updated version of ECN’s modelling tool. Metocean data are first translated to vessel hydrodynamics, ...
