Lng (liquefied Natural Gas) Train
IndustryA single end-to-end processing unit that cools natural gas into liquid form for storage and export. Large LNG facilities run multiple trains, each requiring dedicated construction, maintenance, and shutdown crews. Subcontractors are typically mobilised per train, making scope and schedule highly compartmentalised.
Subsea Architecture
IndustryThe arrangement of underwater equipment — wellheads, flowlines, manifolds, and controls — that connects a seabed well to a surface facility. Subcontractors working in ROV operations, umbilical installation, or inspection services must understand this layout to execute scopes safely. Work packages are often structured around specific architecture components.
COR (Certificate of Recognition)
IndustryA voluntary safety certification program in Canada that recognizes employers who have developed health and safety management systems that meet established standards. Required by many operators in Alberta and Western Canada.
Perforate
IndustryTo create precisely spaced holes or openings in oil well casing and cement at a target formation depth, allowing hydrocarbons to flow into the wellbore; subcontractors providing perforating services typically work under wireline or coiled tubing crews and must coordinate closely with the operator's completion schedule.
WCB (Workers' Compensation Board)
IndustryProvincial agencies in Canada that provide workplace injury insurance. Contractors must maintain WCB coverage and good standing to work on most sites.
Tank Farm
IndustryA designated site containing multiple large storage tanks for oil, gas, or chemicals. Subcontractors frequently perform inspection, maintenance, and cleaning work at these facilities. Access permits and confined space certifications are typically required on site.
