Energieffektiva fartyg med luftkammare

Energy efficient air cavity ships

This research project aims at investigating the hydrodynamic effects that influence the design of an Air Cavity Ship (ACS) for a displacement ship and to give guidance, through knowledge and tool development, for future design of an ACS. The energy saving potential for a VLCC class ship with air cavity is estimated to be close to 20%, i.e. 30,000 MWh/year and ship. An ACS is a ship where a large portion of the flat hull bottom is replaced with an air cavity. The largest contribution to the ship resistance is the friction between the hull and the water, and this way to reduce the wetted surface area of the hull is thus the reason for the large energy saving. The project includes both theoretical work, experiments and a process to transfer the knowledge to industrial parties.
