A method that prioritises equipment inspections based on failure risk and consequence severity. Subcontractors may be required to follow RBI schedules set by operators rather than fixed calendar intervals. Understanding RBI helps field crews anticipate inspection scopes and mobilisation timing.

The process of identifying and quantifying unintended releases of gas, liquid, or vapour from pipelines, valves, or equipment. Subcontractors are often hired to perform LDM (Leak Detection and Measurement) surveys using specialised tools and sensors. Accurate reporting is critical, as findings directly affect regulatory compliance and operator liability.

Federal and provincial rules limiting methane emissions from oil and gas operations. Subcontractors must ensure equipment like compressors and pneumatic devices meets leak detection and repair standards. Non-compliance can result in work stoppages or contract termination.
