Industry Glossary Term

Tidal-Water Export Terminal

A coastal or estuary facility where bulk commodities like LNG or crude oil are loaded onto marine vessels for export. Water depth fluctuates with tides, affecting vessel scheduling and your crew's access windows. Subcontractors must plan shifts and equipment mobilisation around tide tables and vessel berthing schedules.

Related Terms

Oilsands

Industry

Bitumen-rich deposits in northern Alberta requiring large-scale extraction and upgrading operations. For subcontractors, oilsands projects involve extended scopes, remote site conditions, and strict client safety programmes. Work is typically tied to major operators like Suncor, CNRL, or Imperial Oil.

Spring Break-Up

Industry

The seasonal period when melting snow and frost causes ground conditions to soften, restricting heavy equipment access to remote sites. Municipalities impose road bans limiting load weights, delaying material hauls and crew mobilisation. Subcontractors should plan for project slowdowns and reduced billable hours during this window.

Drilling Spread

Industry

The complete package of equipment, personnel, and services required to drill a well, which determines the scope of work subcontractors are hired into — whether supplying a single service line or multiple integrated components across the operation.

AFE (Authorization for Expenditure)

Industry

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

Battery

Industry

A centralised surface facility where oil and gas from multiple wells is gathered, measured, and processed. Subcontractors frequently mobilise to battery sites for maintenance, instrumentation, and civil work. Knowing the battery layout helps crews plan access, logistics, and safe work zones.

Co2 Pipeline

Industry

A pressurised pipeline system that transports carbon dioxide, typically for carbon capture and storage (CCS) projects or enhanced oil recovery (EOR). Subcontractors may be engaged for construction, inspection, or maintenance under strict pressure and corrosion control requirements. Specialised welding certifications and material handling protocols are commonly required for this work.
