The process of verifying and adjusting flow meters, pressure gauges, and other measurement instruments to ensure accurate readings that meet regulatory and client standards — subcontractors providing metering services must maintain current calibration records as proof of compliance and to avoid liability for measurement disputes or billing discrepancies.

A standard governing process safety incident investigation in upstream oil and gas operations. Subcontractors may be required to follow its protocols when involved in a reportable incident on site. Familiarity with it helps field crews meet operator expectations during investigations.

An engineering assessment that determines whether ageing or damaged equipment is safe to keep operating. Subcontractors may be required to provide FFS (Fitness-for-Service) documentation before mobilising older tools or pressure vessels. Clients use these assessments to manage liability and meet regulatory requirements on site.
