Electricity

Marine Electricity or Marine electrical power is a vital part of a ship’s operation. Without marine electricity, ships would not be able to run any of the machinery and cannot perform their core purpose of sailing from one place to another.

We cannot define the term “Marine Electricity” as a whole. To understand its meaning, first, we need to understand them separately.

Marine – Here, the term “marine” refers to ships, ports, drydocks, and other structures which cater to the shipping of cargo by sea.

Electricity – It is a type of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an aggregation of charge or strong as a flowing current.

The electricity which is produced, supplied and distributed onboard a ship, port, drydock or shipyard for running and repair of the cargo- and passenger ships is referred to as Marine electricity.

For ports, shipyards, and structures located inland, marine electricity is utilized from the electricity supply of the land-based power generation plants.

Unlike on land, the ship’s generator has insulated neutral points i.e. its neutral is not grounded or connected to the ship’s hull. This is done to ensure all the essential machinery are up and running even if there is an earth fault.
