Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

PAUT (Phased Array Ultrasonic Testing)

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds, pipelines, and structural components for defects. It produces detailed cross-sectional images without cutting or damaging the material. Subcontractors offering PAUT services typically require certified Level II or III technicians and specialised portable equipment.

Related Terms

Ductile Iron

Industry

A strong, flexible cast iron alloy used in pipes, fittings, and valves on oil and gas and construction sites. It resists cracking under pressure, making it common in water, gas, and slurry line installations. Subcontractors should confirm material specs before procurement, as ductile iron has specific handling and joining requirements.

Design-Build

Industry

A project delivery method where one contractor handles both engineering design and construction under a single contract. As a subcontractor, you may be brought in mid-scope with limited drawing sets, requiring flexibility. Scope creep risk is higher since designs are still evolving while field work begins.

Ultra-Deepwater

Industry

Offshore drilling operations conducted in water depths exceeding 1,500 metres. Subcontractors working these projects require specialised certifications, equipment ratings, and offshore survival training. Mobilisation costs and logistics complexity are significantly higher than shallow-water scopes.

Montney (shale Formation)

Industry

A major tight gas and liquids-rich formation spanning northeastern British Columbia and northwestern Alberta. It is one of Canada's most active drilling regions, generating sustained demand for well service, completions, and civil contractors. Subcontractors working here should expect multi-well pad programmes and remote site logistics.

Distributed Fibre-Optic Sensing

Industry

A monitoring technology that uses fibre-optic cables as continuous sensors along pipelines, wellbores, or structures. It detects temperature, strain, and acoustic changes across kilometres of cable in real time. Subcontractors may be hired to install, splice, or maintain these cable systems during construction or integrity projects.

HRSG (Heat Recovery Steam Generator)

Industry

A large boiler unit that captures exhaust heat from gas turbines to produce steam for power generation. Subcontractors are commonly engaged for HRSG installation, maintenance, and inspection scopes. Work typically requires certified welders, boilermakers, and compliance with pressure vessel regulations.
