Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Lattice Boom

An open-framework steel crane arm made of welded triangular sections, used for heavy lifts on oil and gas or construction sites. Subcontractors must verify lift plans and operator certifications before mobilising lattice boom cranes. Daily rates and rigging crew requirements are typically higher than hydraulic boom alternatives.

Related Terms

Intervention Vessel

Industry

A specialised ship used to perform maintenance, repair, or remediation work on subsea wells and pipelines. Subcontractors are often mobilised to these vessels for ROV operations, well work, or equipment installation. Scheduling and access are tightly controlled by the operator.

Baseload Energy

Industry

The minimum level of power demand that a facility or site requires continuously, around the clock. For subcontractors, it determines whether remote worksites need dedicated generators or grid connections. Stable baseload requirements help crews plan equipment fuel consumption and maintenance schedules.

SAGD (Steam Assisted Gravity Drainage)

Industry

A heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.

Condensate

Industry

A light liquid hydrocarbon that separates from natural gas during production and processing. Subcontractors handling condensate must follow strict hazmat protocols, as it is highly volatile and flammable. It is often measured and valued separately from crude oil on production sites.

Valve Leak

Industry

A valve leak occurs when a valve fails to fully seal, allowing unintended fluid or gas flow. For subcontractors, it often triggers emergency callouts, inspection holds, or scope additions. Document all findings carefully to support change order billing.

Hydrotesting

Industry

A pressure test using water to verify the integrity of pipelines, vessels, or equipment before commissioning. Subcontractors are often scoped separately for hydrotest labour, equipment, and water disposal. Confirm whether these costs are included in your contract or billed as extras.
