Onboard power is produced when a main engine and an alternator work together. For this purpose an alternating current generator is used.

Some points that should be taken into account about the energy produced on board are:

AC, three-phase power is preferred over DC as it gives more power for the same size.

The three-phase is preferred over the single phase, as it obtains more power and in the event of a failure of one phase, the other two can continue working.

The ships power is supplied through circuit breakers and high voltage auxiliary machines.

Emergency power supply

In the event of failure of the ship's main power generation system, an emergency or standby power unit is used, which must ensure that critical machinery continues to operate the ship.

The emergency power supply must be capable of supporting all essential systems such as:

Direction system.
Emergency bilge and fire pumps.
Watertight doors.
Fire system.
Navigation and emergency lights.
