Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Offshore Commissioning

The process of testing and activating offshore systems and equipment before handover to the operator. For subcontractors, this phase typically requires specialised certifications and offshore survival training. Mobilisation costs and remote logistics significantly affect bid pricing and crew planning.

Related Terms

Mission Critical

Industry

Describes any task, system, or equipment whose failure would halt operations or create serious safety risks. For subcontractors, mission critical work often carries stricter response times, higher liability, and tighter documentation requirements.

Rental Power

Industry

Temporary generator or mobile power units leased for a job site instead of purchased outright. Subcontractors use rental power when permanent grid connections are unavailable or impractical. Costs are typically passed through to the client or built into the project bid.

Embankment

Industry

A raised earthen structure used to support roads, pipelines, or equipment pads on unstable or uneven terrain. Subcontractors often work on or around embankments during site prep, grading, and pipeline installation. Stability assessments may affect crew access and equipment positioning.

Leak Detection System

Industry

Equipment and processes used to identify fluid or gas escapes in pipelines, tanks, or wellheads. Subcontractors are often hired to install, inspect, or maintain these systems under strict regulatory timelines. Failing to meet operator specs can trigger contract penalties or work stoppages.

Mainline Pipe

Industry

The primary, large-diameter pipe forming the backbone of a transmission or distribution pipeline system. Subcontractors are typically hired for mainline installation, coating, welding, or hydrotesting scopes. Work on mainline pipe often carries strict inspection and quality requirements.

AISI (American Iron and Steel Institute)

Industry

A standards body that classifies steel grades used in oilfield and construction equipment. Subcontractors reference AISI codes when sourcing pipe, fittings, or structural steel to meet spec requirements. Knowing these grades helps avoid costly material rejections on site.
