Procurement without maintenance is an incomplete service. STO supports the equipment it supplies, and the equipment it inherits, across upstream, midstream, and downstream operations in Nigeria. We track maintenance schedules, inspections, service records, and condition data through the STO Digital Platform, giving clients clear visibility into asset performance. We do not hand over equipment and walk away. We plan, monitor, maintain, and document every intervention because reliability is built through consistent maintenance, not emergency repairs.
PM intervals follow asset criticality and OEM service cycles — not the calendar.
A, B, or C by production impact and failure consequence. Classification sets frequency and spares depth.
Set by hours run and thermal cycles, adjusted for site conditions — not calendar days.
No access without a PTW. No close-out without a signed record.
Every PM date and overdue alert sits on the client dashboard — not an inbox.
Vibration, temperature, and pressure drift flag failure weeks out — if someone's tracking it. Intervention is called by data, logged per asset, with threshold alerts that open a work order automatically.
Response protocols and spares positioning are fixed before the incident — not after.
Root cause confirmed by vibration analysis, thermal imaging, and process history — before a component is ordered.
Critical spares held on-site or fast-tracked per asset class. Mobilisation is a confirmation call, not a procurement cycle.
Every fix closes with a root-cause record and a PM schedule update — visible on the platform without a request.
Full teardown, clearance restoration to OEM tolerance, performance curve validation on reassembly.
Wet-end inspection, seal and bearing renewal, hydraulic performance test before return to service.
Hot-gas path inspection, rotor balancing, laser-verified shaft alignment before restart.
Precision laser alignment and dynamic balancing, logged against the asset record.
Maintenance discipline only holds when the records are consistent and accessible. The STO Digital Platform carries every PM schedule, service record, spare part register, inspection certificate, and NCR — visible to clients, operators, and STO engineers without email requests or site visits.
All PM intervals, upcoming service dates, and overdue tasks — visible by asset, site, or criticality class. No spreadsheets, no phone calls.
Every completed work order, technician sign-off, and replaced component record — searchable by asset tag and date for audit, warranty, and insurance evidence.
Stocking levels, reorder triggers, lead times, and OEM part numbers catalogued per asset — so mobilisation is a confirmation, not a search.
Sensor readings, trend deviations, and threshold breaches are logged continuously against each asset record. When a parameter crosses its set limit, a maintenance workflow opens automatically — no manual trigger required.
Every PM date, CBM alert, and corrective work order lands on one calendar — by asset, site, or status. This is the interface clients get on procurement, not a report someone has to compile.
Hover or tap a card for scope.
Compressors, pumps, turbines, generators, blowers, fans, gearboxes, couplings, and drive systems.
Pressure vessels, heat exchangers, separators, storage tanks, columns, and fired heaters.
Flow transmitters, pressure gauges, level instruments, control valves, analysers, and SCADA/DCS components.
Switchgear, transformers, motors, UPS systems, LV/MV panels, earthing, and generator sets.
Flame detectors, gas detectors, F&G panels, deluge systems, halon systems, and emergency shutdown devices.
Line valves, actuators, PSVs, check valves, pig launchers, pipeline integrity inspection, and piping system maintenance.
Christmas trees, wellhead assemblies, choke manifolds, surface safety valves, and associated tree caps and seals.
Air conditioning, air handling, cooling towers, instrument air compressors, water treatment, and offshore HVAC systems.
PM schedules, service records, condition monitoring data, inspection certificates, and NCR close-outs all live in the STO Digital Platform — visible to clients by asset, by site, or by criticality class, without a phone call. When a regulator, insurer, or auditor requests maintenance history, it is already compiled and retrievable.
