Challenges
The coordination of the ship’s shape, the combustion engine and the propelling screw is one of the main difficulties of traditional ship building. A conventional diesel engine only generates the required speed for the ship screw at 50% of its performance. Apart from that, weight and size of the engine influence the necessary buoyancy, and with that the shape of the ship and finally the propeller approach flow.
With a lower space requirement and weight of the drive, the shape of the stern, the propeller approach flow and thus the efficiency of the propelling screw can be increased by up to 20%, according to the DST (Entwicklungszentrum für Schiffstechnik und Transportsysteme, Development Center for Vessel Technology and Transport systems) in Duisburg, Germany.
