According to the marine steam turbine circulating water pump lubricating oil system, the rotor of the driving steam turbine and the reduction gear box are integrally arranged, the oil tank is located at the bottom of the reduction gear box, the structure is compact, and the using amount and loss of lubricating oil are reduced. A gear lubricating oil pump, an electric lubricating oil pump and a hand-cranking lubricating oil pump are arranged in parallel and are started or stopped according to different steam turbine circulating water pump using working conditions, and efficient operation of the lubricating oil system is achieved. The steam turbine circulating water pump is provided with an oil tank and a lubricating oil cooler, oil supply of a public system of a ship is not needed, when the steam turbine circulating water pump normally operates, a reducer output shaft transmission gear disc drives a gear lubricating oil pump transmission gear and drives the gear lubricating oil pump to operate and supply oil,
