Retractable Azimuth Thruster · Bow/Stern Thrusters
These Wärtsilä WRT-250 thrusters are typically found on large container ships or cruise liners, providing precise and powerful control for maneuvering in busy ports. Operating with a capacity of 2500 kW, these thrusters ensure efficient movement in various sea conditions. Regular maintenance intervals include 5-year inspections and 10-year overhauls, or after 40,000 to 56,000 operating hours. Key areas for inspection include propeller blades, blade foot seals, shaft seals, and lubrication systems. The Sternguard In-Water Serviceable Seal (IWSS) allows for complete underwater serviceability without the need for dry docking. Regularly check for oil leakage, inspect inflatable emergency seals, and ensure compatibility with other seal types to maintain optimal performance and safety at sea.
