PURPOSE: A ship with a redundant power supply system shared by a port propeller and a starboard propeller is provided to easily supply power to an electric motor of a longitudinal propeller in a nominal operation mode and a malfunctioned operation mode when a power system of the electric motor for driving the longitudinal propeller is malfunctioned. CONSTITUTION: A ship with a redundant power supply system shared by a port propeller and a starboard propeller(10) comprises electric networks(12) and a longitudinal propelling chain(14). The longitudinal propelling chain is connected to the electric networks. The longitudinal propelling chain comprises two longitudinal propellers(34). The two longitudinal propellers move the ship to a longitudinal direction(X). Each longitudinal propeller comprises an electric driving motor(36) and a power supply system(38). The electric driving motor is connected to a propeller input part to drive the longitudinal propellers. The power supply system is connected to the propeller input part to supply power to the electric motor.
