Specialized Service for Wärtsilä Marine Propulsion Systems

Whether you require emergency repairs or a complete overhaul, RM Propulsion’s dedicated engineers are ready to support your vessel’s Wärtsilä propulsion systems. With years of hands-on experience, our team understands these systems inside and out.

How Often Should My Wärtsilä Marine Thrusters Be Overhauled?

To maintain optimal performance and comply with classification requirements, Wärtsilä Marine thrusters, along with controlled pitch propellers (CPPs), must undergo scheduled overhauls at defined intervals. Specifically, marine classification societies recommend service every five and ten years.

At RM Propulsion, our expert service engineers provide routine maintenance, inspections, and full overhauls for a wide range of Wärtsilä propulsion systems, such as:

  • Transverse thrusters

  • Retractable thrusters

  • Steerable thrusters

  • Azimuth thrusters

What Do Our Five- and Ten-Year Overhauls Involve?

To ensure optimal performance and extend service life, Wärtsilä thrusters, including steerable and tunnel-mounted units, are generally recommended to undergo major overhauls every 10 years, or after approximately 40,000–56,000 operational hours.
At RM Propulsion, our five‑ and ten‑year maintenance intervals align with these standards to meet both classification requirements and best-practice guidelines.

 

The five‑year overhaul begins with dismantling and inspection of the thruster to assess its internal condition.
We then clean all components thoroughly and replace wear-prone parts, such as seals, gaskets, and lubrication elements, to restore performance and reliability.

In contrast, the ten-year overhaul, or after approximately 40,000 hours of operation, is significantly more comprehensive.

 

At this stage, we carry out in-depth component replacements, such as:

  • Bearings

  • Liners

  • Blade foot seals

  • O-rings

  • And other critical internal elements

To sum up, these structured maintenance intervals help prevent unplanned downtime and ensure long-term system integrity. With RM Propulsion, you get tailored overhaul solutions backed by years of Wärtsilä- specific expertise.
