Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Fixed Equipment Integrity

The ongoing assessment and maintenance of stationary assets like pressure vessels, piping, and heat exchangers to ensure safe operation. Subcontractors are often hired to perform inspections, repairs, and fitness-for-service evaluations on this equipment. Work must align with owner specifications and regulatory standards such as those set by the Alberta Boilers Safety Association.

Related Terms

Decommissioning

Industry

The process of safely shutting down and dismantling oil and gas infrastructure at end-of-life. For subcontractors, it generates significant work in removal, remediation, and site restoration. Scopes often include demolition, equipment salvage, and regulatory closeout tasks.

Pump Station

Industry

A facility that moves oil, gas, or water through a pipeline using mechanical pumps. Subcontractors are frequently mobilised to pump stations for maintenance, inspection, and equipment servicing work. These sites often require specific safety certifications and site orientations before work begins.

Frontier Exploration

Industry

Exploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.

Tieback

Industry

A structural anchor or connection point used to secure equipment, pipelines, or wellheads back to an existing infrastructure system, commonly referenced in subcontractor scopes of work when connecting new installations to live or existing lines. Subcontractors should confirm tieback specifications and isolation procedures clearly in their contracts, as this work often involves elevated risk and may require additional certifications or permits.

Crude Oil Stock Build

Industry

A rise in stored crude oil inventories, signalling weak demand or oversupply. This often triggers operators to slow production, which can delay or reduce field service work orders. Subcontractors should monitor stock build trends as an early indicator of project slowdowns.

NGL (Natural Gas Liquids)

Industry

Hydrocarbons extracted from natural gas, including propane, butane, and condensate. NGL facilities and pipelines generate steady subcontract work in processing, instrumentation, and maintenance. Understanding NGL handling requirements helps crews meet site-specific safety and equipment standards.
