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.
Leak Detection and Measurement
Related Terms
Methane Mitigation
ComplianceEfforts to detect, reduce, and report methane emissions from oil and gas operations. Subcontractors may be required to use low-bleed equipment, perform leak detection, and document emissions. Clients increasingly include methane mitigation requirements in scopes of work and contracts.
Sif-P (serious Injury and Fatality Potential)
ComplianceA classification applied to incidents or near-misses where the outcome could have caused death or life-altering injury. Operators use SIF-P ratings to trigger mandatory investigations that subcontractors must participate in. Field crews are expected to identify and report SIF-P exposures before work begins.
Hot Works
ComplianceAny task that produces open flame, sparks, or heat sufficient to ignite flammable materials. Common examples include welding, cutting, and grinding. Subcontractors typically require a Hot Works permit before starting, and site compliance checks are strict.
Consequential Damages
ComplianceIndirect losses a party claims resulted from a contractor's failure, such as lost production revenue or project delays. Most subcontracts include a mutual waiver clause excluding these claims entirely. Always confirm this waiver is present before signing any field service agreement.
Leading Indicators
ComplianceProactive metrics that signal future safety or performance issues before incidents occur. For subcontractors, these include near-miss reports, toolbox talk attendance, and equipment inspection rates. Tracking them helps crews stay ahead of problems rather than reacting after the fact.
Trench Safety
ComplianceProtocols and regulatory requirements for protecting workers in excavations deeper than 1.2 metres. Subcontractors must implement shoring, sloping, or trench boxes before workers enter. Non-compliance can result in stop-work orders, fines, and liability on your contract.
