Class-leading Offshore Energy Support Vessel (OESV) operator, Seacat Services,
has secured a long-term contract with Equinor, which will see three specialist OESVs support the ongoing operations and maintenance (O&M) of the 88-turbine Sheringham Shoal Offshore Wind Farm off the coast of Norfolk. 

According to the contract, two of Seacat Services’ 21-metre vessels – Seacat Endeavour and Seacat Reliance – will operate on site all year round, and between March and October they will be joined on site by a larger 24-metre catamaran. 

The vessels and crews will provide specialist logistical support to the Equinor technical teams, assisting with scheduled and unscheduled maintenance by conducting safe transfer of technicians and O&M equipment to and from Wells Harbour. Also they will provide class-leading levels of technical availability to fulfil all contracted obligations towards Equinor to the highest standards. Furthermore, retaining Seacat Services on a long-term basis will create opportunities to build relationships between operations teams, technicians and vessel crews, ensuring operational familiarity and consistency, and a best practice approach to on-site safety.

Ian Baylis, Managing Director of Seacat Services, said: “A high standard of vessel support is a critical factor in the safe and cost-effective operation of an offshore wind farm. The industry is increasingly recognising the importance of stable supplier relationships to drive operational efficiencies, combined with the logistical versatility to ensure maximum ‘time on turbine’ for technicians.”

Karl Butler, Power Plant Manager, Equinor, said: “Collaboration and close relations with our suppliers is essential to ensure safe and efficient operations. We are looking forward to working with Seacat Services and wish all the team a warm welcome to Sheringham Shoal.”

The Sheringham Shoal project consists of 88 turbines, each with a capacity of 3.6MW, which were put into operation in 2012.
