Selected issues on the methodology of determining the efficiency of a ship’s energy system in different operating states

Michalski R., Zeńczak W.

The article presents the methodology and algorithm for determining the efficiency of a ship’s energy system, which can be helpful at both operation and design stage. Knowledge of the methodology discussed here and the definitions of a ship's energy system’s efficiency may be particularly useful for operators, as particularly complicated energy conversion chains exist on specialized units, such as fishing vessels, which have many devices that can be driven by different types of engines and transmissions. Proper disposal of energy streams allows for their optimal use and for a reduction in fuel consumption, whose cost constitutes the largest share of the vessel's operating costs.
