On ships, 3 phase 3 wire system is used and neutral of generator reamains hanging or floating or isolated. All machineries onboard a ship are earthed to the ship's hull. The advantage of this kind of system is that if earth fault occurs on any one of the phases, the supply will not get afftected and machinery keep on working. This is the priority on marine platforms. Howevr, if one more earth fult occurs on the remaining phases, this condition will become like short circuit throught ship's hull and protection will operat to isolate the defective source and power supply for the machinery will be interrupted.
