Environmentally sound design of the newbuildings starts from hull shape. It helps to diminish carbon dioxide emissions by 25 per cent compared to current ships due to relatively long and thin hull form. Extensive model tests in open water were performed at SSPA in Sweden and ice model tests at Aker Arctic Technology in Helsinki, Finland in order to find the optimal hull shape. In order to minimize hull resistance, all welding seams under load waterline are grinded smooth.
A lot of effort has been put to design rudder and propeller arrangements to enable low consumption. The Deltamarin-designed rudder is equipped with bulb and end plates to optimize the flow from main shaft to rudder. In addition, there are four stator fins both in the main shaft in order to improve current to the propeller which has a diameter of six meters. Bow and stern thruster openings have scallops and grids that improve hydrodynamics.
