Commercial Maritime Specialists

Engineering Reliability for Commercial Marine Operations

Precision services for cargo vessels, offshore support ships, tankers, and ferries.

Datum RMS delivers class-certified, on-vessel engineering services to keep your propulsion, cargo handling, and critical marine systems operating efficiently.

Pinpoint developing faults and avoid catastrophic failures.

Vibration Analysis

Class-compliant surveys using ISO-certified analysts and high-resolution diagnostics. Suitable for main propulsion, pumps, compressors, and auxiliary systems.

Motion Amplification

Visualise microscopic movement in marine machinery and structures using optical vibration technology, ideal for identifying structural resonance or soft foot.

Ultrasonic Analysis

Non-invasive detection of bearing defects, leaks, and mechanical wear using high-frequency ultrasound.

Infrared Thermography

Thermal imaging of switchboards, motors, gearboxes, and other high-load components, detect overheating before it causes breakdowns.

Eliminate misalignment, reduce vibration, extend bearing life.

Laser Shaft Alignment

Fast, accurate alignment of propulsion systems, generator drives, cargo handling equipment, and more.

Strain Gauge Measurement

Strain guage measurements with mathmatical modelling to calculate bearing loads

Optical Alignment

Precision optical measurement for long-distance shaftlines and critical mechanical interfaces.

Corrective machining services – line bore works, lathe and milling.

Line Bore & Restoration

Restore bearing housings, stern tubes and other bores to OEM tolerances – carried out in situ.

Workshop Machining

Bespoke lathe and milling work to suit projects

Protect critical shaftline components with marine sealing solutions

Shaft Seal Replacements

Supply and fit of marine-grade shaft seals (including mechanical seals, lip seals, and labyrinth types) engineered to reduce leakage, prevent contamination, and extend component life.

Shaft Seal Troubleshooting

Root-cause analysis of premature seal failures. Expert advice to optimise your system.

Sealing Systems

Guidance on optimal sealing solutions for propulsion shafts, pump drives, and gearbox outputs, available for both retrofit and new build.

Built for Demanding Marine Environments

Commercial vessels demand more than general engineering. You need marine-certified diagnostics, fast port-based interventions, and minimal disruption to your operational schedules.
