Industry Glossary Term

Proactive Maintenance

Scheduled inspections and repairs performed before equipment fails, reducing costly downtime on job sites. Subcontractors who offer proactive maintenance services can secure longer-term service agreements with operators. It also helps avoid liability tied to unexpected breakdowns during active contracts.

Related Terms

HDPE (High-density Polyethylene)

Industry

A durable, corrosion-resistant plastic used for pipes, containment liners, and fluid transfer systems on job sites. Subcontractors commonly install or tie into HDPE pipelines in water, gas distribution, and environmental remediation scopes. Its lightweight nature reduces handling costs but requires certified fusion welding for pressure-rated connections.

CIP (Capital Improvement Program)

Industry

A planned cycle of major infrastructure upgrades or expansions at a facility, often releasing large volumes of subcontract work. For field service companies, CIPs signal sustained project pipelines worth pursuing long-term agreements for. Monitoring client CIP schedules helps subcontractors forecast workload and mobilise crews strategically.

SPMT (Self-propelled Modular Transporter)

Industry

A multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.

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.

Lattice Boom

Industry

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.

TVD (True Vertical Depth)

Industry

The straight-line vertical distance from surface to a specific point in a wellbore, regardless of how the well is drilled — subcontractors working on directional or horizontal wells need to reference TVD (not measured depth) when scoping equipment reach, calculating hydrostatic pressures, or verifying work zone depths on service orders.
