The improvement comprises an additional lubricating oil pump having a drive shaft, a suction pipe connected to said sump and a delivery pipe. A clutch is interposed between said additional pump drive shaft and the transmission driven shaft. A branch pipe is interposed between said supply pipe and said clutch and transmission gear with normal pressure maintaining said clutch disengaged. A fall in pressure in the main lubricating oil supply pipe permitting engagement of said clutch kinematically-connecting said driven shaft to said auxiliary pump drive shaft to drive said additional pump. A tank is supported above said transmission gear and said additional pump delivery pipe outlets into said tank. A series of gravity feed lubricating pipes are interposed between said tank and said transmission gear. A valve is connected to each of said pipes and to said electric supply system; said valves being respectively opened and closed with the failure of the ship's electric supply system, for maintaining lubrication to said transmission gear.
