Servicing Brunvoll® Thrusters

Technical support, emergency repairs, routine overhaul and spare parts

To ensure vessel safety and propulsion reliability, thrusters require expert overhauls every 5 to 10 years. Although RM Propulsion operates independently of OEMs such as Wärtsilä®, Rolls-Royce®, Kamewa®, MAN®, and Kawasaki®, we are thoroughly familiar with their systems. As a result, we offer brand-agnostic expertise across a wide range of platforms, including Aquamaster®, Berg®, Brunvoll®, and beyond. In short, we deliver trusted support without the limitations of OEM dependency.

RM Propulsion, Your Trusted Partner for Brunvoll Thruster Service

-Expert Support. Proactive Maintenance. Long-Term Reliability.-

To begin with, keeping your Brunvoll® marine thruster system in peak condition requires structured and timely care. At RM Propulsion, we offer specialized service for Brunvoll thrusters backed by deep technical knowledge and hands-on experience. Importantly, we are fully independent from Brunvoll® as a manufacturer, which means we provide objective, cost-effective service without brand restrictions. Moreover, we also supply compatible spare parts for Brunvoll® thrusters, often at a better price than the OEM, without compromising on quality or performance.

By combining regular servicing with cost-effective parts, you reduce the risk of failure, extend equipment lifespan, and ensure long-term reliability at sea.

Why Regular Brunvoll Thruster Service Matters

-Because performance and reliability go hand in hand.-

Over time, key components of your thruster system, such as seals, bearings, and shafts, become vulnerable to wear. Common issues include oil leakage, water ingress, and corrosion. If left unchecked, these issues can escalate into full system failure or even pose environmental hazards.

Therefore, addressing these vulnerabilities through preventive maintenance is not just smart, it’s essential. It significantly reduces operational risks, preserves propulsion efficiency, and extends the overall service life of your equipment. In other words, regular service for Brunvoll thrusters is a strategic investment in reliability and peace of mind.

Five and ten-year Service for Brunvoll thrusters & more by RM Propulsion

Ensure the long-term performance and compliance of your Brunvoll thruster with our structured service program. At the five-year mark, or roughly 20,000 operating hours, we perform a preventive overhaul that includes full disassembly of the thruster, detailed inspection and cleaning, and replacement of essential wear parts like shaft seals and blade-foot O-rings. This way, the intermediate service allows us to identify early signs of wear, corrosion, or water ingress, ensuring your equipment continues to meet classification standards and operate reliably without unexpected downtime.

At the ten-year point, a comprehensive overhaul becomes essential to preserve the integrity of the thruster. We perform a complete tear-down and in-depth inspection of internal components including bearings, gears, shafts, and liners. Depending on their condition and OEM tolerances, critical elements such as seals, bearings, liners, and O‑rings are replaced. The thruster is then reassembled according to original specifications and subjected to final testing to confirm safe, smooth, and fully compliant operation.

With this full overhaul, your Brunvoll thruster is ready for the next 5 years.
