Some ships generate electrical power at 440 Volts, but then step up this voltage to supply specific electrical equipment. One common example, may be to feed a large bow thruster. Why is this done?

A large bow thruster will draw very large currents at low voltage. Being typically remote from the generator, significant voltage drops would occur at low voltage.

The shipyard could not purchase High Voltage generating plant at the time of manufacture, so they used what was available at the time.

Manufacturers can supply High Voltage bow thrusters at less cost, and the power factor is improved.

The overall ship's electrical load does not justify High Voltage generating plant. This method allows more power to be delivered to the bow thruster at low running cost.
