This paper presents a design concept to overview the feasibility of utilizing modern energy storage systems as substitution of conventional machinery auxiliaries, which are necessarily installed to support internal combustion engines' operation. For example, the common compressed air system required for engine starting and emergency stopping occupies substantial space in the machinery space of the ship. Owing to increased capacity and reduced price of batteries nowadays, electric motors and solenoid valves can supersede the compressed air system, and we can save space and reduce capital expenditures as well. The cranking torque for engine starting, motor driving current, the optimal control system is simulated to validate the performance of the engine starting system, in line with the simulation of charging and discharging of an energy storage system.
