Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Large-Load Interconnection

The process of connecting high-demand electrical equipment to a utility grid, often required for large compressors, pumps, or processing facilities. Subcontractors may face project delays while operators await utility approval and infrastructure upgrades. Timelines can stretch months, directly affecting mobilisation schedules and contract start dates.

Related Terms

Lower 48

Industry

Refers to the contiguous United States, excluding Alaska and Hawaii. For subcontractors, it defines a common work jurisdiction with distinct regulatory, tax, and labour rules from Canadian or Alaskan operations. Mobilisation costs and compliance requirements differ significantly when crews cross into or out of this region.

Energy Transition

Industry

The global shift from fossil fuels toward renewables, hydrogen, and lower-emission energy sources. For subcontractors, it means new project types, updated certification requirements, and evolving client scopes. Diversifying skills into solar, wind, or carbon capture work helps firms stay competitive.

Best-Value Selection

Industry

A contractor award method where clients evaluate price alongside factors like safety record, experience, and equipment quality. Subcontractors are not automatically disqualified for submitting the lowest bid. Demonstrating strong credentials and reliability can outweigh a competitor's cheaper rate.

Wall Thickness Assessment

Industry

An inspection process that measures remaining material thickness in pipes, vessels, or structural components to detect corrosion or erosion. Subcontractors are often hired to perform these assessments using UT (Ultrasonic Testing) equipment. Results determine whether assets require repair, replacement, or continued monitoring.

Telehandler

Industry

A versatile, telescoping-boom forklift used on job sites to lift and place materials at height or over obstacles. Subcontractors commonly use telehandlers for offloading deliveries, staging equipment, and accessing elevated work areas. Operators typically require provincial certification to run one on a regulated site.

Surface Coil System

Industry

A temporary heating system using fluid-filled coils laid on the ground to thaw frozen soil or maintain process temperatures. Subcontractors are often hired to install, monitor, and remove these systems during cold-weather operations. Common in northern pipeline and facility projects where ground conditions affect construction timelines.
