The UK’s national Operations & Maintenance (O&M) Centre of Excellence has partnered with Ørsted in a £400k project to develop sea state forecasting, which aims to deliver a significant reduction in missed working days.

The Humber-based O&M Centre of Excellence (OMCE) is a £2 million collaboration between the University of Hull and the Offshore Renewable Energy (ORE) Catapult to drive solution-focused innovation and improvements in O&M.

The project team, led by academics from the University of Hull, is working closely with Ørsted to help improve wave forecast modelling with direct industrial impact. The model will contribute to improving the accuracy of sea state forecasting at an individual offshore wind turbine level with the potential to drive efficiency gains in operations and maintenance, increasing safety, as well as contribute to further reductions in the Levelized Cost of Energy (LCoE) for offshore wind.

Turbine accessibility is a key determinant of a wind farm’s profitability. Technicians attempting to undertake maintenance can face a number of barriers to safe access, which in turn can be a factor in limiting turbine performance and ultimately overall energy output of a wind farm. This new project aims to develop a wave forecasting model that will give greater accuracy and offer a more granular insight into the sea state within an offshore wind farm than current state-of-the-art methods can.

Multiple downward-facing radar have been installed at turbines at Ørsted’s
Burbo Bank Extension wind farm off Liverpool to record wave height, direction and period together with combined met-ocean data and existing forecasts. This big-marine-data approach, along with bathymetry and site configuration data, is enabling researchers to produce an artificial intelligence-based method that will be used to make a step-change in the resolution and accuracy of fine-scale at offshore wind farm sites.

Led by the University of Hull, Ørsted and ORE Catapult are also partners in Aura. Led by the University of Hull, Aura is a collaboration of academics, industry, governmental organisation, and training bodies, working to support offshore wind development.
