Naval and Marine

From Dock to Deep Sea—We Keep You Operational

With shrinking defence budgets and ageing fleets, naval and marine operators are under pressure to extend the life of mission-critical rotating equipment—without compromising on performance or compliance. At Mawdsleys, we’ve built a dedicated engineering cell to serve this exact need.

Our Bristol location gives us a strategic advantage, allowing us to respond quickly to port locations across the UK. We understand your standards. We meet your deadlines. And we get the job done right.

Repair and maintenance

Stern motors. Generators. Pumps. Fan units. These aren’t just components—they’re lifelines. When they go down, so does your operation. That’s why more naval and marine clients are turning to Mawdsleys.

We specialise in the refurbishment and repair of specialist rotating electrical equipment to the highest standards, including compliance with Defence Standard Issue 21. Our experienced engineers carry out thorough mechanical and electrical checks to ensure every repair meets military-grade expectations.

If it’s critical, we can repair it. If it’s complex, we’ve done it before.

Design and manufacture

We know that one size never fits all. That’s why we offer bespoke design and manufacture of electrical rotating equipment tailored to your specific operational demands.

Whether you need a modern replacement for legacy components or a custom-built unit to meet newly defined specs, Mawdsleys delivers. We work with you from concept to installation—solving the unique problems standard suppliers can’t. And we build it all to meet the exacting standards the naval sector demands.

Because off-the-shelf doesn’t work when failure isn’t an option.

Noise & vibration testing

Your equipment might work—but does it operate within the required radiated noise and vibration thresholds? In the naval world, silence can be as important as strength.

Our state-of-the-art testing facilities use high-precision transducers and advanced measurement techniques to ensure your systems comply with every regulation—without sacrificing performance. We test both new and in-service equipment and work closely with clients to keep fleets compliant, mission-ready, and fully operational.

When the stakes are high, turn to a partner who understands the pressure, the standards, and the pace. Turn to Mawdsleys.
