Commercial Maritime Specialists
Engineering Reliability for Commercial Marine OperationsPrecision 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.
Rotating Machinery Diagnostics
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.
Precision Alignment Services
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
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
Sealing & Reliability Upgrades
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.
