Industry Glossary Term

Liquefaction

The process of converting natural gas into liquid form (LNG) by cooling it to extreme temperatures for storage and transport. Subcontractors supporting liquefaction facilities must meet strict safety and technical certifications. Work scopes often include maintenance, insulation, and cryogenic system servicing.

Related Terms

Building Electrification

Industry

The process of replacing fossil fuel-based systems in buildings with electric alternatives, such as heat pumps and induction equipment. For subcontractors, it drives demand for electrical, HVAC, and mechanical retrofits. Crews must often hold updated certifications to work on high-voltage systems and EV (Electric Vehicle) charging infrastructure.

Hub

Industry

A central staging location where crews, equipment, and materials are coordinated before deployment to remote job sites. For subcontractors, the hub determines mobilisation routes, laydown areas, and logistical costs. It often serves as the main point of contact between the prime contractor and field crews.

Perforate

Industry

To 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.

PCP (Progressive Cavity Pump)

Industry

A rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.

Tank Farm

Industry

A 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.

Dewatered Sand

Industry

Sand or granular material that has had excess water removed, typically through drainage or mechanical separation on site. Subcontractors handling dewatered sand face stricter disposal and hauling requirements than wet slurry. Confirm moisture content specs before mobilising equipment or quoting removal work.
