A generator set can be used as power source for various applications on-board. This allows you to reduce the required number of diesel engines on-board, or to have an additional backup available when needed.
With tankers, for example, electrically driven cargo pumps and bow thrusters aboard are frequently fed with the same generator used to manoeuvre the vessel or vice versa.
When combining it does not matter whether the generator should operate at a fixed speed, variable (electric shaft) or a combination thereof. Veth Propulsion can provide you with a suitable generator of any combination.
