A method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.
Trenchless
Related Terms
Embankment
IndustryA raised earthen structure used to support roads, pipelines, or equipment pads on unstable or uneven terrain. Subcontractors often work on or around embankments during site prep, grading, and pipeline installation. Stability assessments may affect crew access and equipment positioning.
OSHA
IndustryOccupational Safety and Health Administration. The US federal agency responsible for workplace safety regulations. Compliance with OSHA standards is required for contractors working in the United States.
Long-Lead Procurement
IndustryThe advance ordering of materials or equipment with lengthy manufacturing or delivery timelines. For subcontractors, delays in these items often push back mobilisation dates and affect project cash flow. Always confirm long-lead delivery schedules before locking in your crew start dates.
Behind-The-Meter
IndustryRefers to power generation or energy systems located on a client's side of the utility connection point. For subcontractors, this often means working on site-owned generators, solar arrays, or battery storage on industrial or remote worksites. Scopes here fall outside utility jurisdiction, affecting permitting and inspection requirements.
Run Schedule
IndustryA timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.
VRU (Vapour Recovery Unit)
IndustryA compression system that captures hydrocarbon vapours from storage tanks or production equipment instead of venting them. Subcontractors are often hired to install, maintain, or service VRUs to meet emissions regulations. Familiarity with VRU work is increasingly required on oil and gas production sites.
