Technology Concept for Half Fuel Oil Consumption Vessel

抄録

To realize the Half Fuel-Oil Consumption Vessel under the same conditions of cruising speed and deadweight, it is necessary to choose and integrate drastic and significant energy saving techniques. These are reducing hull frictional resistance on the vessel's flat bottom by air bubbles lubrication, enhancing propulsive efficiency by twin large diameter propellers with twin-skeg hull form, recovery of rotational energy in the propeller slipstream by fins, recovery of the waste heat from the main engine with binary thermal energy conversion system, and utilization of wind energy in the sea with high performance hard wing sail. It is suggested that the integration of the above-mentioned techniques makes the Half FOC Vessel possible in the near future.
