Windcat Workboats, part of the SEACOR Marine Group, signed a contract with Swedish electricity company Vattenfall for the provision of CTVs (crew transfer vessels) for the Dutch coast Zuid 1 and Zuid 2 offshore wind farm in the Dutch North Sea. Under the agreement, Vattenfall will be one of the first users of Windcat's hydrogen-powered vessels. The IJmuiden-headquartered offshore crew supply vessel operator is working with CMB Technologies on the vessel development, which is expected to be completed by the third quarter of 2020.
The hydrogen CTV, named HydroCat, will be able to transport 24 service engineers from the coast to the offshore windmill farms at a cruise speed of 25 knots, propelled by two 1,000-hp engines and will consume 170 kilogrammes of hydrogen per day.
The 700-MW project Zuid 1 and 2 will be one of the world's first offshore wind projects built without public subsidies. The wind farm, located 22 km off the coast, is expected to be commissioned in 2022.
