Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Mini Crawler Crane

A compact, track-mounted crane used for lifting in confined or access-restricted job sites. Subcontractors rely on them where standard cranes cannot manoeuvre. Common in industrial shutdowns, pipeline work, and tight construction corridors.

Related Terms

Greenfield

Industry

A project built from scratch on a previously undeveloped site, with no existing infrastructure. For subcontractors, this means longer mobilisation timelines and higher early-stage labour demand. Expect more scope changes and stronger opportunities for long-term contract work.

Vacuum Excavation (vac-Ex)

Industry

A non-destructive digging method that uses high-pressure water or air to loosen soil, then suctions it into a debris tank. Subcontractors use it for safe excavation near buried utilities, pipelines, and cables. It is commonly required on oil and gas sites where mechanical digging poses strike risks.

Dual-Class Share Structure

Industry

A corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.

Opec+ (organisation of the Petroleum Exporting Countries Plus)

Industry

An alliance of oil-producing nations that controls global crude output levels. Their production decisions directly affect upstream activity and subcontractor demand. When OPEC+ cuts output, drilling and field service work typically slows; increases often trigger new project mobilisations.

Ngl (natural Gas Liquid) Fractionator

Industry

A processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.

RAP (Reclaimed Asphalt Pavement)

Industry

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.
