Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Gas Rigs

Drilling rigs specifically configured to drill natural gas wells, requiring crews and equipment rated for high-pressure gas formations. For subcontractors, gas rigs often demand specialised certifications and H2S training. Work volumes typically follow natural gas commodity prices and seasonal heating demand.

Related Terms

Vam Connections

Industry

Premium threaded pipe connections used in oil and gas drilling and completion operations. Subcontractors handling, installing, or inspecting VAM connections must follow strict torque specs and handling procedures. Improper makeup can result in costly downhole failures and liability exposure.

MEP (Mechanical, Electrical, and Plumbing)

Industry

Refers to the three core building systems subcontractors install and maintain on construction and industrial facility projects. MEP scopes are often divided among specialised trades, each holding separate contracts or working under a prime contractor. Understanding MEP divisions helps subcontractors define their scope, avoid overlap disputes, and price work accurately.

FFS (Fitness-for-service)

Industry

A structured engineering assessment that determines whether ageing or damaged equipment is safe to keep operating. Subcontractors are often hired to collect inspection data, run integrity tests, or execute repairs recommended by FFS evaluations. Understanding FFS scope helps field crews prioritise work orders and meet client fitness thresholds before returning assets to service.

Sole-Source Contract

Industry

A contract awarded directly to one subcontractor without a competitive bidding process. Operators use this when your firm has specialised expertise, proprietary equipment, or an urgent mobilisation is required. It can mean faster contract execution but often comes with tighter scope and pricing scrutiny.

Cook Inlet

Industry

A major oil and gas producing basin in southcentral Alaska with active offshore and onshore operations. Subcontractors working here face remote logistics, tidal extremes, and strict environmental regulations. Mobilisation costs and specialised marine requirements significantly affect bid pricing.

Switchgear

Industry

Electrical equipment used to control, protect, and isolate power systems on job sites. Subcontractors working near switchgear must follow strict lockout/tagout procedures. Installation and maintenance work often requires certified electricians and site-specific safety permits.
