The paper discusses the current problems of increasing the efficiency of turbine drives for ship auxiliary mechanisms. Replacing a number of individual turbine drives for ship mechanisms with a pair of drives that are mechanically unconnected by counter-rotating impellers will increase the operational efficiency of the vessel. The research process has yielded the main geometric, regime, power and torque parameters depending on the speed characteristic for an active turbine stage with counter-rot
