Abstract: The design scheme of the variable frequency fan for a 20 000 TEU container ship is given as the optimum efficiency point of the engine-room fans under the variable working conditions are determined by fitting the efficiency curve. The energy-saving effect that can be produced by installing the variable frequency system on the engine-room fan is estimated by analyzing the environmental climate and the different working conditions of the typical Eurasian routs. A reasonable economic benefit analysis method is finally put forward for the fan with the variable frequency system.
