Industry Glossary Term

Material Takeoff

A detailed list of all materials, quantities, and specifications needed to complete a scope of work. Subcontractors use it to prepare accurate bids and avoid costly shortages or overruns in the field.

Related Terms

Deepwater

Industry

Refers to offshore oil and gas operations conducted in water depths exceeding 300 metres, where subcontractors and field service crews must hold specialised certifications, work within stricter regulatory frameworks, and often face extended mobilisation timelines and higher equipment day-rates.

Npr-A (national Petroleum Reserve in Alaska)

Industry

A federally managed exploration zone on Alaska's North Slope, open to oil and gas development. Subcontractors working here face strict federal permitting, remote logistics, and seasonal access limitations. Mobilisation costs and compliance requirements are significantly higher than standard onshore projects.

Grid Interconnection

Industry

The process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.

Condensate

Industry

A light liquid hydrocarbon that separates from natural gas during production and processing. Subcontractors handling condensate must follow strict hazmat protocols, as it is highly volatile and flammable. It is often measured and valued separately from crude oil on production sites.

Compression

Industry

The mechanical process of increasing natural gas pressure for pipeline transport or storage. Subcontractors are frequently mobilised to install, maintain, or repair compressor units and associated equipment. Compression work is common in gas processing facilities, wellsites, and midstream pipeline operations.

In-Service Date

Industry

The date when equipment or a facility is officially commissioned and begins active operation. For subcontractors, this date often triggers billing milestones, warranty periods, or contract close-out requirements. Missing this date can result in penalties or delayed final payment.
