MOL’s System Cuts Fuel Consumption

Offshore testings have confirmed more than 5% reduction in fuel consumption as a result of installation of a waste heat energy recovery system on the bulk carrier Azul Brisa, according to Mitsui O.S.K. Lines, Ltd. (MOL).

The system recovers waste heat energy of the main engine and uses it to generate electricity with a hybrid supercharger equipped to generate power, and a turbo generator, which is combined with steam turbine.

The electricity generated not only meets onboard power demands but also assists the ship’s propulsion via the shaft motor fitted to the crankshaft of main engine.

This reduces fuel consumption of both the power generator and the main engine, which contributes to a reduction in CO2 emissions as well.

The waste heat energy recovery system is one of the steps taken toward future marine engines in the ISHIN-III next-generation series of vessels that MOL announced back in April 2010.
