This type of propulsion aims to reduce the fuel consumption of ships working under different duty ranges.

The idea is to optimise the overall efficiency of the propulsion to use up less energy and yet achieve the same result, and thus to reduce pollution.

Electric energy is usually produced by four diesel generator sets that are sized to meet the ship’s power requirement.

As a rule, the higher the power requirements, or the more additional or alternative drives are required with respect to the main propulsion, the greater the interest of this solution.
