Installing smaller battery capacity to a diesel engine driven vessel with electrical power train can enable spinning reserve. Here, an optimal number of engines can be kept online, and the batteries can work as a black out preventer. This can save, depending on the type of the ship and operation, anything between a few percent to tens of percent if the ship is otherwise required to keep a huge reserve of engines online.
In addition to spinning reserve, the batteries can perform peak shaving function, to further ensure that the engines are kept on fixed load close to the fuel efficiency optimum point. For these two functions, the battery capacity does not have to be large. It is mainly for various zero emission operation modes or even covering the main voyage time, when larger capacities are required.
Having batteries for spinning reserve or peak shaving for a cargo’s ship auxiliary machinery powertrain can also similarly optimize the genset efficiency. Cargo ships typically have large thrusters or cranes that take large quantities of power for
