Industries We Serve
Engineering strategy built around the risk profile, standards, and operating realities of your industry.
Industries We Served
Moving your facility from reactive maintenance to Predictive Integrity using AI-driven data modeling.
Why Industries Need Engineering Strategy?
Every industry carries risk differently. A refinery’s exposure comes from ageing equipment and hydrocarbon inventory; a power plant’s comes from equipment criticality to generation uptime; a manufacturing floor’s comes from direct worker exposure during maintenance and changeover. Applying the same generic safety framework across all of them misses what actually drives risk in each environment.
Pure Integrity builds engineering strategy around the specific risk profile, standards, and operating context of each industry we work in, so recommendations are grounded in how your plant actually runs, not a generic checklist.
Different Approach Per Industry
Refinery
Risk: High hydrocarbon inventory across densely interconnected units, with ageing equipment often operating past original design assumptions.
Standards: IEC 61511, RBI, RCM-driven maintenance frameworks.
Outcome: Demonstrated ALARP compliance, fit-for-purpose maintenance strategy, sustained plant uptime.
Oil & Gas
Risk: Brownfield assets with layered modifications over field life, cumulative drift between original hazard studies and current operating reality.
Standards: IEC 61511, ISO 14224, HAZOP revalidation per CCPS guidance.
Outcome: Revalidated HAZOP nodes, improved asset register completeness, shift from time-based to risk-based maintenance.
Petrochemical
Risk: Reactive chemistry and interdependent utility systems built from a blank sheet, a narrow window to embed the safety basis before construction locks decisions in.
Standards: IEC 61511, ISO 14224, HAZOP/HAZID per IEC 61882 and CCPS methodology.
Outcome: HAZOP/LOPA closure against FEED-to-detailed-design milestones, complete asset register at handover.
Power Plant
Risk: Equipment criticality to generation availability, unplanned failure means lost revenue and grid-reliability exposure, not hydrocarbon release.
Standards: ISO 14224, RCM frameworks aligned to SAE JA1011/1012.
Outcome: Reduced unplanned outage hours, FMEA/RCM-optimised maintenance tasks, asset register completeness.
Manufacturing
Risk: Direct worker exposure to mechanical, electrical & stored-energy hazards during maintenance and changeover, not large-scale process consequence.
Standards: LOTO / energy-isolation principles, HIRARC per DOSH Malaysia, ISO 45001.
Outcome: Reduced isolation-related near-misses, equipment-specific LOTO procedures developed.
