A section of pipeline, conduit, or cable routed beneath or across a river, creek, or other body of water. Crossings typically use methods like horizontal directional drilling (HDD) or open-cut trenching. Subcontractors must meet strict environmental permits and inspection requirements before and after installation.

Building Electrification
IndustryThe 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.
Vacuum Excavation (vac-Ex)
IndustryA non-destructive digging method that uses high-pressure water or air to loosen soil, then suctions it into a debris tank. Subcontractors use it for safe excavation near buried utilities, pipelines, and cables. It is commonly required on oil and gas sites where mechanical digging poses strike risks.
NPRA (National Petroleum Reserve-alaska)
IndustryA large federally managed area in northwest Alaska open to oil and gas exploration and development. Subcontractors working here face extreme remote logistics, strict federal permitting, and seasonal access windows. Mobilisation costs and compliance requirements are significantly higher than conventional onshore projects.
CPF (Central Processing Facility)
IndustryA fixed surface facility where oil, gas, and water from multiple wells are separated, treated, and prepared for transport or sale. For subcontractors, a CPF is often a long-term, high-activity work site requiring trades, maintenance, and operations crews. Scope can include initial construction, commissioning, turnarounds, and ongoing maintenance contracts.
Third-Party Contracting
IndustryAn arrangement where a primary contractor hires an outside company to perform specialised work on a project. For subcontractors, this defines your position in the contracting chain and affects payment terms, liability, and site access. Knowing your tier level helps clarify who you invoice and who manages your compliance requirements.
FRP (Fibre-reinforced Polymer)
IndustryA lightweight, corrosion-resistant composite material used in piping, grating, and structural components on oilfield and construction sites. Subcontractors encounter FRP in offshore platforms, chemical plants, and water treatment facilities. It requires specialised handling and cutting procedures to avoid hazardous dust exposure.
