Bow Thruster · Bow/Stern Thrusters
Crew members, engineers, and operators on board ships depend heavily on thrusters for safe navigation and maneuvering. The Wärtsilä WTT-35 tunnel thruster, with its robust design and wide power range (400 kW to 5500 kW), ensures reliable operation in various maritime conditions. Featuring a tunnel diameter of 3500 mm, it provides efficient lateral thrust necessary for precise ship movements. The WTT-35 includes advanced features like the Sternguard In-Water Serviceable Seal (IWSS) and integrated hydraulic systems with fine filtration to enhance reliability and reduce maintenance costs. Regular inspections and overhauls every five to ten years are recommended to ensure optimal performance, addressing common issues such as propeller blade erosion, seal wear, and hydraulic oil contamination.
