CRIST has completed the construction of a semi-equipped marine wind farm service unit - NB 313 "Acta Centaurus". The unit was constructed according to the SX195 project developed by the Ulstein Design & Solutions AS design office. The ship is 93 m long, 18 m wide, has 3 200 t load capacity and 6 meter draft. The SOV (service operation vessel) unit will work on the construction, assembly and maintenance of offshore wind farms. The ship will be equipped with a hybrid battery pack, a helicopter landing pad and a telescopic traffic compensation system mounted on an integrated tower with height adjustment and a lift for load and personel. Additionally, X-BOW and X-STERN solutions as well as a special 3D crane (6 t lifting capacity), SMST trap and elevators will ensure that the unit maintains a proper position when entering the wave and lower energy consumption. Acta Centaurus will be efficient and safe even with 3-meter waves. The ship will develop the speed of the 13t knots, and 120 people will be able to work on it.
