Industry Glossary Term

ROV (Remotely Operated Vehicle)

An unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.

Related Terms

Peaking Facility

Industry

A peaking facility is an energy plant activated only during periods of high demand, such as extreme cold snaps. For subcontractors, these sites generate short-notice, high-intensity work orders requiring rapid crew mobilisation. Expect compressed timelines and premium billing opportunities during activation periods.

Caustic Service

Industry

Work involving equipment or piping that handles highly alkaline chemicals, such as sodium hydroxide. Subcontractors must use compatible materials and certified personnel to avoid rapid corrosion and serious chemical burns. Specialised PPE and handling procedures are typically required by the client's safety plan.

GPR (Ground-penetrating Radar)

Industry

A non-destructive scanning method that detects buried utilities, pipes, and subsurface anomalies before excavation begins. Subcontractors use GPR to reduce strike risk and meet dig-permit requirements on job sites. Many clients now require GPR clearance as a condition of mobilisation.

Support Activities for Oil and Gas Operations

Industry

An industry classification covering subcontractors who provide services to upstream oil and gas producers without extracting resources themselves. This includes well servicing, site prep, equipment rental, and pipeline support. Most field service companies in oil and gas fall under this category for tax and regulatory purposes.

Acreage Position

Industry

The total land or mineral rights an operator holds for exploration or production. A large acreage position often signals sustained work programmes and long-term subcontractor demand. It helps field service companies forecast pipeline opportunities in a region.

Hydrovac

Industry

A truck-mounted unit that uses pressurised water and a vacuum system to excavate soil safely around buried utilities. Subcontractors are frequently hired for hydrovac work on pipeline, civil, and utility projects. It is preferred over mechanical digging in areas with high strike risk.
