Industry Glossary Term

Battery

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.

Related Terms

Production Shut-in

Industry

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

Co-Location (data Centre)

Industry

A shared facility where subcontractors rent server space instead of maintaining their own IT infrastructure. This reduces overhead costs for smaller field service companies managing dispatch, invoicing, and project data. Providers handle power, cooling, and security at the facility.

Corridor (pipeline Corridor)

Industry

A designated strip of land reserved for pipeline installation, operation, and maintenance. Subcontractors must confine all work, equipment, and materials within its boundaries. Corridor limits directly affect site access, staging areas, and crew movement on linear projects.

Letter of Interest

Industry

A formal document a subcontractor submits to a prime contractor or operator to express intent to bid on upcoming work. It is not a binding commitment, but helps secure a spot in the tender process. Common in pre-qualification stages for large oilfield or construction scopes.

Duct Bank

Industry

A grouped arrangement of conduits encased in concrete, used to route electrical or communication cables underground on job sites. Subcontractors installing or excavating near duct banks must follow strict dig protocols to avoid damaging live services. Identifying duct bank locations early prevents costly delays and liability.

Grid-Scale Battery Storage

Industry

Large battery systems that store megawatts of electrical energy for power grids or remote industrial sites. Subcontractors install, commission, and maintain these units on energy and construction projects. Work includes civil foundations, electrical integration, and ongoing service contracts.
