Hydrocat is the result of a joint venture between CMB.TECH and Windcat Workboats. It is a dual fuel (hydrogen – diesel) vessel that will provide transfers for crew and equipment on maintenance activities for offshore wind parks



  • Daily hydrogen refuelling of 200kg
  • Saves 1.9 tonnes of carbon dioxide per day
  • Maximum speed of 30 knots
  • Bollard pull of 13,3 ton

The excess wind energy produced by offshore wind farms can be used to produce clean, economical hydrogen. This hydrogen gas can then be used to power the dual-fuel Hydrocat vessel, minimizing the environmental impact of the operation and maintenance of the wind farm.

The workboats have a track record of over 950,000 transfers, and the design of the vessel results in a fast and safe transfer of offshore personnel.

These vessels can also be used for a range of activities, supporting both construction and the operation and management of an offshore wind farm, such as emergency response, standby, survey and dive support vessels.
