Thrustmaster hydraulic tunnel thrusters consist of a high thrust fixed pitch propeller on a husky propeller shaft directly coupled to Thrustmaster’s exclusive podded hydraulic motor providing infinite propeller speed control in both directions of rotation. They come as complete units installed in a section of steel tunnel. They are available in tunnel diameters from16 to 84 inches covering a power range from 30 to 2000HP. Thrusters from 16 to 36 inches are also available in aluminum. For detailed specifications, please ask for our Technical Specifications. Thrustmaster hydraulic tunnel thrusters are simple, quiet, efficient and extremely smooth while exhibiting all the benefits of the ideal tunnel thruster. Precise Control when you need it most The variable-flow hydrostatic drive system allows for infinite propeller speed control in port and starboard direction. Whether in manual mode or DP mode, hydraulic thrusters allow perfect vessel station-keeping and instant thrust response. Full thrust can be reversed within 3 to 5 seconds. This instantaneous and fully proportional speed control gives performance superior to a controllable pitch propeller (CPP) without the cost, complexity, fragility or maintenance problems of the intricate CPP control system with all its drive shafts, levers and feedback mechanisms.
