The factory and production of all thrusters is based out of Houston, Texas with a global network of sales offices in Rotterdam, Singapore, China, Dubai, and Brazil. A service office is located in Houma, Louisiana to assist offshore clients. All thrusters are developed in-house by a complete engineering department for mechanical, hydraulic, electrical and electronic design. Tooling includes machining and measuring equipment, CAD, vessel resistance and propulsion, 3D modeling and ANSYS Finite Element Analysis. The application of modal analysis, stress and strain analysis as well as rotor dynamic analysis of drive trains and transmissions are fundamentals towards the reliability and quality of Thrustmaster’s products.

(762 mm) up to 136 in. (3,455 mm). Made with fixed pitch propellers, Thrustmaster’s tunnel thrusters are designed for diesel engine driven or variable speed electric motor input in the L-Drive configuration. A bi-directional electric motor with variable frequency drive can be mounted horizontally or vertically on the thruster depending on the given space restrictions. A diesel engine with a marine gear can also be used. Thrustmaster tunnel thrusters have been installed in many vessels operating around the world. Thrusters can be supplied complete with electric motors and drives or they can be made to fit flange and shaft end of a customer supplied or shipyard supplied electric motor. Many sizes are available. Please contact our sales department for your application. Some models have ABS Type Approval. Thrusters up to and including model 90TT2000-ML do not require external cooling – any heat generated by the gears and bearings is dissipated through the pod housing to the surrounding seawater. Models larger than 90TT2000-ML require an external lubrication circulation and cooling system. This lubrication system is included in Thrustmaster’s scope of supply   Send a Sales Inquiry View Specs Downloads Thrustmaster Corporate Brochure Tunnel Thruster Components Propeller The propeller is a four blade symmetrical tunnel thruster propeller with fixed pitch. It is cast from nickel aluminum bronze. The propeller shaft seals are contained in a 316 SS seal housing with rope guard. The seal housing is provided with bidirectional line cutters, preventing fishing lines and nets from damaging the seals. Bi-directional Line Cutters The seal housing is provided with bidirectional line cutters, preventing fishing lines and nets from damaging the seals. Lube Oil Head Tank (For thruster models up to and including 90TT2000ML) The thruster assembly is fully flooded with lubrication oil. A sepa-rate header tank is provided for installation above the vessel water-line to help prevent incursion of water into the propeller shaft seal. The header tank is a steel tank complete with level indicator, tem-perature indicator, filler/breather, and LOW/HIGH level switch. A sight glass is also included to visually monitor the oil level. Lube Oil Circulation System Thrusters larger than model 90TT2000ML use a lube oil circulation system for cooling and filtration of the lubrication oil. The lube oil circulation system is a skid mounted packaged system comprising an electric motor driven screw pump, a filter unit and a heat exchanger complete with interconnecting lube oil piping within the skid limits. The lube oil expansion tank may be provided as a separate item for installation above the maximum waterline of the vessel. Tunnel Thruster Remote Controls The bridge panel features Joystick Control and a LCD (Liquid Crystal Display) panel that conforms to a variety of programmed features. A built-in Electrical Control Unit (ECU) provides proportional thrust control from zero to full rpm in both the port and starboard direction. The joystick is friction held style. The basic control panel includes brightness and contrast adjustments, emergency stop button, audible alarm buzzer, and alarm indicators. The LCD also provides visual control transfer protocol between bridge control panels (when using multi-ple remote panels), plus; logic for interpreting the VFD status and its control (when using a VFD) logic and input/output (I/O) for DP system command and feedback (if DP interface option is included) logic for the thruster status and control (digital and analog I/O signaling) motor and VFD alarms and fault status information Thrust control is proportional to the angle of the joystick lever which is friction held with a center detent for neutral position. The digital readout displays alarms and system status and shows directional feed-back in the form of a directional indicator. Panels are drop-in style with positive twist-lock connections in back. Tips on Thruster Selection As a rule of thumb, a bow thruster used for docking and undocking should be capable of producing thrust in pounds of force (lbf) equal to twice the lateral cross sectional vessel area below the water in square feet or two to three times the lateral cross sectional area of the superstructure above the water, whichever is greater. Sizing of tunnel thrusters for slow speed maneuvering and station keeping depends greatly on the vessel operating parameters. Before making your final selection, consult your naval architect or one of Thrustmaster’s application engineers. When using tunnel thrusters in waters with high current or while the vessel has forward speed, the thruster becomes less effective. At vessel speeds of 3 knots, the tunnel thruster may lose as much as 25 percent of its thrust. At speeds of 7 knots, the thruster may only produce half of its rated thrust. A Thrustmaster retractable azimuthing thruster may be more appropriate for these applications. Tunnel thrusters need to be placed below the waterline to prevent air ingestion. If the top of the tunnel is too close to the surface of the water, vortexes may develop, resulting in air from the surface being sucked into the tunnel. This causes airlock, substantial reduction in thrust, excessive noise and vibration, and severe shock leading to the thruster. Consider the vessel draft in unloaded vessel condition. If the thruster is to be used out in open seas, consider vessel heave and roll and consider wave action in determining how far below the waterline your thruster needs to be placed to prevent air ingestion. (See also Tips on Thruster Installation) If space does not allow proper submergence with a single tunnel thruster on a shallow draft vessel, two or more smaller tunnel thrusters, installed side by side, may be used. Multiple Thrustmaster tunnel thrusters can be powered by a single prime mover with a common hydraulic system, making the thrusters act in unison as if they were a single thruster.
