Based on the patented Ulstein Alfa Lift design, the vessel has been dedicatedly developed to serve the global offshore wind market. Because of her capabilities, OHT ASA has with this vessel been awarded the contract to install the wind turbine foundations for the world's largest offshore windfarm Dogger Bank A & B.
