Oil analysis programmes by industry.
The same test means different things in a dusty mine, a clean pharmaceutical utility, a ship at sea or a continuous steel mill. Start with the sector, then connect equipment, fluids, failure modes, sampling and action.
Choose the operating environment.
Each guide maps common equipment to routine and triggered tests, preferred sampling practice, programme priorities and maintenance outcomes.
Mining & Quarrying
Dust, shock load, long shifts and remote operation make contamination control and early wear detection central to mobile-equipment reliability.
- Haul trucks and loaders
- Excavators and shovels
- Crushers and conveyors
Steel & Metals
Heat, water, scale and high hydraulic loads demand disciplined cleanliness, water control and varnish surveillance.
- Rolling-mill hydraulics
- Mill gearboxes and pinion stands
- Continuous-caster and furnace systems
Construction & Heavy Equipment
Variable operators, idling, dusty sites and mixed duty cycles require compartment-level trends and strong sampling discipline.
- Excavators, dozers and graders
- Cranes and access equipment
- Generator and compressor packages
Marine & Shipping
Fuel quality, onboard treatment, engine wear and water exposure must be interpreted from bunker manifold to engine inlet and machinery sump.
- Main and auxiliary engines
- Bunker storage and treatment
- Gearboxes, thrusters and deck hydraulics
Aviation
Safety-critical fluids require specification-controlled sampling, traceability and specialist interpretation with no substitution for approved maintenance data.
- Aircraft gas turbines
- Aircraft hydraulic systems
- Airport fuel storage and hydrants
Industrial Manufacturing
A mixed asset base benefits from criticality-based panels covering gearboxes, hydraulics, compressors, machine tools and central lubrication.
- Production gearboxes
- Hydraulic power units
- Compressors and vacuum pumps
Chemical & Process Industries
Process-fluid ingress, high temperatures and continuous operation require attention to lubricant compatibility, oxidation and contamination pathways.
- Process compressors
- Pumps, mixers and gear drives
- Heat-transfer systems
Pharmaceutical
Product-safety, clean utilities and contamination control require segregated sampling and clear distinction between food-grade lubricant conformance and machine condition.
- Clean-air and utility compressors
- Granulators, mixers and packaging drives
- Chillers and HVAC systems
Food & Beverage
Washdown, water ingress and product-contact risk make lubricant identity, grease condition and contamination control especially important.
- Conveyors, mixers and gear drives
- Refrigeration compressors
- Hydraulic and packaging systems
Power Generation & Utilities
Turbines, engines, transformers and balance-of-plant systems require long-term trends, high-quality sampling and coordinated multi-technology monitoring.
- Gas and steam turbines
- Generator engines
- Power transformers
Oil & Gas
Remote critical compressors, turbines, pumps and drilling equipment need robust sampling, contamination control and hazardous-service awareness.
- Gas compressors and turbines
- Drilling and production hydraulics
- Pumps and gear drives
Cement & Minerals
Dust, shock load, high temperatures and large gear drives make wear debris, contamination and lubrication practice decisive.
- Raw and cement mills
- Kiln drives and support rollers
- Crushers, fans and hydraulics
Data Centres & Critical Power
Standby engines, stored fuel, cooling systems, transformers and mechanical utilities must remain ready despite low run hours and high failure consequence.
- Standby diesel generators
- Bulk and day-tank fuel systems
- Transformers, chillers and cooling utilities
Wind & Renewable Energy
Remote access, variable load and costly crane mobilisation make gearbox, hydraulic, grease and transformer trends valuable for planned intervention.
- Main gearbox and generator bearings
- Pitch, yaw and hydraulic systems
- Pad-mounted transformers and substations
Rail, Transit & Logistics
High utilisation, timetable pressure, idling and repeated thermal cycles require compartment-level trends that support safe planned maintenance.
- Locomotives and heavy-duty fleet engines
- Transmissions, axles and final drives
- Air compressors, hydraulics and workshop fuel
Forestry, Pulp & Paper
Water, fibre, dust, high loads and continuous production make cleanliness, demulsibility, bearing and gearbox evidence central to reliability.
- Harvesters, skidders and mobile equipment
- Paper-machine circulating and hydraulic systems
- Dryer drives, refiners and process gearboxes
Agriculture & Off-Highway
Seasonal peaks, dust, long storage and shared implements require disciplined fluid identity, contamination control and pre-season baselines.
- Tractors, combines and harvesters
- Irrigation pumps and stationary engines
- Grain handling, feed mills and conveyors
Define consequence, duty and failure-development time.
Select tests that can reveal the credible wear, contamination and degradation mechanisms.
Fix location, operating state, container and context.
Use trend, corroboration and site procedures to choose the next step.
