CT-FP (Controllable-Pitch Tunnel) 1100kW

Regular inspections and diligent maintenance are crucial for ensuring reliable operation of Wärtsilä's CT-FP (Controllable-Pitch Tunnel) 1100kW thrusters. Key areas include the propeller blades, which should be visually inspected and tested regularly to ensure optimal efficiency; the blade root seals must be checked every five years and replaced as needed due to their critical role in preventing water ingress. Similarly, the shaft seals require attention every five to ten years, with full replacement recommended for thorough maintenance. Bearing inspections are also essential, especially for signs of wear and pressurization issues, which can be monitored using specific measuring tools. The integrated hydraulic system must be closely managed for oil quality and filtration, with periodic changes and checks to prevent contamination. With these maintenance steps in place, the CT-FP 1100kW thrusters from Wärtsilä can perform reliably over their long service life.
