Industry Glossary Term

Underground Electrical Distribution

A system of buried cables and conduits that delivers power across a site without overhead lines. Subcontractors must locate and verify these lines before any excavation or ground disturbance. Unmarked or mislabelled lines create serious safety and liability risks on job sites.

Related Terms

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.

Network Interconnection

Industry

The linking of separate communication systems so field crews, dispatch, and client sites can share data in real time. For subcontractors, this enables job updates, timesheets, and safety reports to flow between systems without manual re-entry. Reliable interconnection reduces billing delays and keeps remote sites aligned with head office.

Gas-Directed Rig Count

Industry

The number of drilling rigs actively targeting natural gas formations at a given time. A rising gas-directed rig count signals increased demand for field services and subcontractor crews. Tracking this metric helps you anticipate work volumes and mobilisation timelines in gas-heavy basins.

Lng (liquefied Natural Gas) Train

Industry

A single end-to-end processing unit that cools natural gas into liquid form for storage and export. Large LNG facilities run multiple trains, each requiring dedicated construction, maintenance, and shutdown crews. Subcontractors are typically mobilised per train, making scope and schedule highly compartmentalised.

Header System

Industry

A network of pipes that collects flow from multiple wells or lines into a single outlet point. Subcontractors often tie into or maintain header systems during facility hookups and commissioning work. Knowing the configuration is critical for safe isolation and pressure management on site.

Oil-Directed Rig Count

Industry

The number of rigs actively drilling for oil, tracked weekly by services like Baker Hughes. A rising count signals increased demand for field crews, equipment, and well-site services. Subcontractors use it to anticipate work volumes and adjust capacity accordingly.
