Abstract

The acticle presents a method for minimizing energy exploitation of the ship through reducing ship resistances. Ship resistances include water resistances caused by frictions of water and waves acting on hull part in the water and air resistance acting on the hull part above water surface. To reduce the resistance caused by water friction, the authors proposed a method which intervene directly on the boundary layer of ship hull by the creating a gas injection foaming layer. To reduce air resistance, the authors used CFD method to optimaze arrangement of container on deck for a container ship. Obtained results showed that the proposed method help to save 5-8% of the consuming energy.
