Tunnel Thruster · Bow/Stern Thrusters
Crew and engineers on board vessels rely heavily on robust propulsion systems to ensure safe and efficient navigation, especially in challenging marine environments. Kongsberg/Rolls-Royce's TT-750 stern tunnel thruster is a critical component of these systems, providing reliable performance with a power output of 750 kW and a thrust of 90 kN. The thruster features a diameter of 1100 mm, making it suitable for various vessel sizes and operational requirements. Regular maintenance is essential to keep the TT-750 functioning optimally. Key inspection areas include the propeller blades, which should be checked for wear, cracks, or deformation. The propeller shaft seal must also be inspected for leaks and wear, with a focus on monitoring the pressure and replacing seals during major overhauls. Additionally, the bearing clearance and condition of hydraulic fluid and lines are crucial for maintaining performance and preventing failures. Ensuring these components are in good condition helps extend the life of the thruster and maintains its efficiency.
