Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Continuous Outage

A scheduled shutdown where equipment or a facility remains offline for an extended, uninterrupted period. Subcontractors are often mobilised for the full duration to complete inspections, repairs, and upgrades. Scope changes mid-outage can affect crew size, timelines, and billing.

Related Terms

Maintenance Capital

Industry

Funds spent to keep existing equipment and infrastructure operational rather than expanding capacity. For subcontractors, client maintenance capital budgets directly drive demand for inspection, repair, and servicing contracts. Tighter maintenance capital spending often signals reduced field work volumes ahead.

Life Extension Drydock

Industry

A scheduled out-of-water inspection and refit that extends a vessel's certified operational life beyond its original design limit. For subcontractors, it signals a concentrated burst of multi-trade work including hull repairs, coating, and systems upgrades. Scopes are often fast-tracked, creating strong short-term demand for specialised labour and materials.

Henry Hub

Industry

A natural gas pricing benchmark set at a Louisiana pipeline hub, widely used in North American supply contracts. When Henry Hub prices rise, upstream activity increases and subcontractor demand typically follows. Monitoring this index helps field service companies anticipate project volumes and negotiate rates.

Stress-Corrosion Cracking

Industry

A failure mode where metal components crack under the combined effect of tensile stress and corrosive environments. Subcontractors must inspect susceptible equipment — like pipelines, pressure vessels, and lifting gear — for early signs. Missed SCC (Stress-Corrosion Cracking) damage can trigger costly shutdowns, liability claims, or failed inspections.

Tubulars

Industry

Steel pipes used in drilling and well construction, including casing, tubing, and drill pipe. Subcontractors handling tubulars must follow strict inspection and handling procedures. Damage during your scope can result in costly liability claims.

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.
