The application of such concept in the international freight vessel is rare yet but could improve its safety and operability with an aid of the extra power boost and absorption by an energy storage device. Such a novel concept is tested for heavy sea conditions using simulation of a multi-physical domain model. A very large crude oil carrier with a shaft generator is chosen as a simulation case where an electric battery pack is added on the electrical power plant. Specific models and simulation tools for vessels, propellers, internal combustion engines, ship electrical system and controllers are presented and validated to the available performance data. The result of the simulation showed that having an energy storage device enables to utilize the shaft generator as an active aid to propulsion with allowable influence on the generator load. In addition, the system efficiency is equivalent to the conventional system even without optimizing the plant. Finally, co-simulation using the functional mockup interface(FMI) standard is tested to see improvement in computational time of the complex simulation. The co-simulation result is verified against the result of simulation in allin-one fashion. It shows good agreement and significant improvement in computational speed.
