BMT has recently completed the design for a pair of wind farm support vessels (WFSV), for operation in Japan, and currently in build by Cheoy Lee Shipyards at the Hin Lee (Zhuhai) Shipyard facility.

BMT designed the new 27m vessel specifically for operations and maintenance of the Akita and Noshiro offshore wind farms, in the Akita Prefecture region of Japan. This is the first large-scale commercial offshore wind project in the country with an expected combined output of 139 MW. BMT undertook metocean data studies which have enabled the vessel design to be tailored to the local conditions, ensuring the manoeuvrability, performance and redundancy of the vessel are optimised for its operational environment.

“As the first utility-scale offshore wind project in Japan, BMT are pleased to secure this vessel design order and to support Akita Offshore Wind Corporation (AOW) in the development and operation of the Akita Noshiro Offshore Wind Farm Project,” said James Lewis – BMT Specialised Ship Design sector lead for Offshore Energy. “As Japan progresses towards a clean energy future powered by offshore wind, BMT are ready to play our part, along with the rest of the AOW partners.”

The design is a fully classed vessel, built to Class NK rules, and fitted with BMT’s patented Active Fender System. Each vessel is capable of carrying 12 technicians and three crew and provide safe, comfortable and reliable technician transfers allowing AOW to carry out efficient operations and maintenance activities off the shores of Japan.

Powered by four engines with four waterjets, the vessel will provide high fuel efficiency during different modes of operation as well as redundancy. The WFSV will travel at up to 25 knots, with a deadweight capacity of 30 tonnes to meet ever expanding O&M requirements for wind turbines. The first WFSV is set to be launched in December 2020, with delivery in early 2021.
