erating conditions so that the battery lifespan is maximized. Charging rates, charging frequency, depth of discharge and end-of life capacity are all impor- tant considerations in achieving the optimum energy storage solution. Vir- tual prototyping and simulations pro- vide further insight to match energy storage against mission pro? les.

“Integrating hybrid capability into a vessel propulsion system is not with- out its challenges,” says Lee. “Space must be reserved for electric machines, couplings, batteries, switchgear and controls. Weight is a signi? cant factor which in? uences the vessel size to op- timize vessel ef? ciencies and minimize propulsion power demands. There are a multitude of options when it comes to hybrid integration, so with careful- ly considered design, this equipment can be integrated onto almost any ves- sel. Ultimately, each vessel has differ- ent requirements; therefore, a custom approach is always needed to ensure the integration is successful for the builder, operator and crew.”

Electric equipment company Molabo of Germany supplied the power system for a recently-delivered ? re-? ghting and rescue boat built by the Finnish shipyard Kewatec.
