Operations & Maintenance
Long-term service agreements that keep plants running. Preventive maintenance, predictive diagnostics, managed spares pools, and 24/7 technical support.
How we work
Our O&M offering ranges from spot maintenance interventions to multi-year long-term service agreements (LTSAs). Scope can include preventive maintenance schedules, predictive maintenance using vibration and thermography monitoring, managed spare parts pools at site, 24/7 technical support hotline, and performance optimisation.
For specialised equipment, we offer repair-and-return services and obsolescence management — finding replacement parts for legacy systems that the original manufacturer no longer supports.
What you receive.
Common questions about Operations & Maintenance.
How do LTSAs work?+
Long-term service agreement covering preventive maintenance schedules, predictive condition monitoring, spares supply, performance optimisation and operator-facing reporting. Typical contract 3-7 years with annual KPI review and price escalation. Contract structure varies — fixed price per year, cost-plus-fixed-fee, or unit-rate — depending on the operator's preference.
What predictive maintenance techniques do you use?+
Vibration analysis on rotating equipment (turbines, compressors, pumps, fans, motors), thermography on electrical equipment, oil analysis on gearboxes and transformers, motor current signature analysis, ultrasonic for steam-trap and bearing diagnostics. The diagnostics feed an operator-visible asset health dashboard so decisions are transparent.
How do you manage spare-parts pools?+
Managed at site with minimum-maximum levels reviewed quarterly. Criticality analysis drives the stocking decision (production impact × replacement lead time). Vendor-managed inventory available for high-volume operators where we hold stock and replenish on consumption. Obsolescence reviews twice yearly to flag end-of-life parts before the operator is exposed.
What 24/7 technical support do you provide?+
Hotline with regional engineering on call. Response-time SLAs in the contract — typical first-response 30 minutes, on-site within 24 hours for critical incidents. The first-call engineer triages and either resolves remotely or escalates to the right specialist. Every call is logged and reviewed in the monthly operations meeting.
How do you handle obsolescence?+
Active monitoring of OEM lifecycle bulletins, last-time-buy notifications, equivalent-part identification, retrofit engineering. We're independent of OEM commercial pressure — if the OEM's published replacement is overpriced or has an unsuitable form factor, we identify and qualify the right alternative rather than push the operator into a forced retrofit.
Do you offer repair-and-return for legacy modules?+
Yes — legacy DCS modules, drive control cards, PLC CPUs, instrumentation transmitters. Tested and certified back to manufacturer specifications. Genuine OEM parts only — no clone fixes that void certification and create liability for the operator. Repair-and-return is significantly cheaper than new procurement when the manufacturer still supports the part.
