Accurate diagnosis starts with experience. We identify issues, investigate their causes and provide clear, practical solutions to keep your vessel performing reliably.
Preventative maintenance and professional servicing designed to maximise reliability, minimise downtime and keep your vessel ready for use.
From essential repairs to technical engineering work, we deliver meticulous workmanship to the highest professional standards, ensuring lasting reliability and peace of mind.
From initial assessment to final reporting, we follow a clear and thorough process designed to keep your vessel reliable, safe and ready for use.
We begin with a thorough assessment of the vessel and its systems, establishing a clear understanding of their current condition. Through an initial inspection, we identify potential issues, assess areas that may require attention and define the maintenance requirements needed to support long-term reliability and performance.

Once the initial assessment is complete, we investigate the vessel’s systems in greater detail. Through detailed diagnostics and technical analysis, we identify faults, trace their underlying causes and evaluate the condition of the relevant components. This allows us to provide clear, practical recommendations based on the actual requirements of the vessel.

With the findings established, we carry out the necessary repairs, maintenance and engineering work with a focus on precision and reliability. Every solution is approached with careful attention to detail and professional workmanship, addressing the underlying issue rather than simply treating the symptom, with the aim of restoring dependable performance and minimising future downtime.

Once the work is complete, we provide a clear report detailing our findings, the work carried out and any recommendations for future maintenance, giving you full transparency and a reliable record of your vessel’s condition.

Owners, captains and management companies who return to RPM Engineering for the same standard of work.
“Ross is a skilled, knowledgeable, and reliable contractor who I look forward to working with every time we return to Vilanova. It is refreshing to have someone on board who works cleanly and efficiently. I trust him to not only tackle the projects at hand but also suggest improvements that have resulted in an easier workload throughout my season. He is truly an asset to any vessel requiring outside engineering”
“I am pleased to recommend RPM Engineering following their work on the main engine of S/Y Silvertip, a 112ft sailing yacht during her refit at Pendennis Vilanova. Ross and team demonstrated excellent professionalism, technical expertise and attention to detail throughout the project. Communication was clear and efficient, and they worked seamlessly with our crew and other contractors. Their support during the sea trial and commissioning was particularly appreciated, ensuring the main engine was thoroughly tested and properly monitored. As Captain, I would have no hesitation in recommending RPM Engineering for their professional and reliable service.”
