The reduction of power consumption in the marine power engineering system is a way to decrase the emission of harmful exhaust gases components into the atmosphere, reduction of the vessels' operational costs and decreasing the amount of crude oil waste arising during fuel processing on ships.
The solution of this problem can be achieved by maximising the recovery of waste heat from main propulsion diesel engines. The waste heat contained in exhaust gases, supercharging air and cooling water, may be used to increase the amount of electric power produced on the ship, heating energy and the amount of fresh water produced.
