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.

Some main propulsion medium speed engine installations operate with a hydraulic oil type fluid coupling between the engine and the reduction gearbox instead of a mechanical clutch. With this type of installation a separate flexible coupling is not normally fitted. Why is a separate flexible coupling usually omitted from this type of installation?

There is insufficient room to fit a flexible coupling between the engine and gearbox when a fluid coupling is fitted.

There are no engine torque variations in the drive when a fluid coupling is used so a flexible coupling is not required.

The hydraulic fluid in the coupling isolates the gearbox from the engine vibrations.

There is natural slippage between the drive and driven parts of the fluid coupling and a flexible coupling would prevent this slippage.
