Earthing System in Ships & Marines

Ships & marines do not require an earthing conductor per se, as the body of water in which they float is sufficiently conductive to enable a proper earth connection to be provided without supplementary conductors.

Hope it would help you.....

Effectively, the metallic body of the vessel is the earth conductor for the sources of electrical energy provided within it.

Arrangements are specifed in British Standard 7671 for the connection of shore-based sources of energy and their accompanying earth conductors to electrical loads based in vessels.

Earthing system in ships earth connnected to star piont of transformer/ generator.

There is no earthing system in ships and marines. But There is some protection arrangements for the leakage current to vessel.

Connects to hull.
