Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Equipment Uptime

The percentage of scheduled time that equipment is operational and available for use on a job site. For subcontractors, high uptime directly affects billing hours, client satisfaction, and contract renewals. Downtime caused by mechanical failure or poor maintenance often falls on the subcontractor to remedy at their own cost.

Related Terms

Topside Fabrication

Industry

The construction and assembly of the above-water structures on offshore platforms, including decks, modules, and processing equipment, where subcontractors are typically engaged for specialised trades such as structural welding, pipefitting, electrical, and instrumentation work. For field service companies, topside scopes often involve strict offshore safety certifications, remote logistics, and milestone-based billing tied to fabrication progress.

Stimulation

Industry

Well stimulation refers to treatments like hydraulic fracturing or acid jobs that improve reservoir flow. Subcontractors often mobilise for short, intensive campaigns requiring specialised crews and equipment. Scope changes and standby time are common, so clear contract terms matter.

Turnaround

Industry

A planned shutdown of a facility for maintenance, inspection, and repair. Turnarounds often require large numbers of contractors and subcontractors working intensive schedules.

Minimum Work Program

Industry

A contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.

Alternative Delivery Models

Industry

Contracting arrangements beyond traditional lump-sum or day-rate structures, such as alliance, integrated project delivery, or performance-based contracts. These models shift how subcontractors are engaged, paid, and held accountable for outcomes. Understanding them helps field service firms assess risk, pricing strategy, and scope responsibilities before signing.

Trenchless Method

Industry

A pipeline or conduit installation technique that avoids open excavation, using methods like HDD (Horizontal Directional Drilling) or pipe bursting. Subcontractors use it to cross roads, waterways, or environmentally sensitive areas with minimal surface disruption. Specialised equipment and certifications are typically required, affecting crew composition and bid pricing.
