Industry Glossary Term

ROV (Remotely Operated Vehicle)

An unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.

Related Terms

SPP (Southwest Power Pool)

Industry

A regional transmission organisation managing the electrical grid across 14 U.S. states. Subcontractors working on power infrastructure, grid upgrades, or energy facilities in this region must align with SPP reliability standards. Understanding SPP's operating rules helps field crews coordinate outages and energisation schedules.

Brent Crude

Industry

A globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.

Legacy Well

Industry

An older well built to outdated standards that may require specialised remediation, abandonment, or workover services. Subcontractors should expect non-standard equipment configurations and additional compliance requirements. Scope creep and unforeseen costs are common on legacy well projects.

Integrated Project Delivery

Industry

A project structure where owners, contractors, and subcontractors share risk, costs, and rewards under one agreement. Subcontractors gain earlier involvement in planning but face shared liability for delays or overruns. Payments are often tied to collective project milestones rather than individual scopes.

HRSG (Heat Recovery Steam Generator)

Industry

A large boiler unit that captures exhaust heat from gas turbines to produce steam for power generation. Subcontractors are commonly engaged for HRSG installation, maintenance, and inspection scopes. Work typically requires certified welders, boilermakers, and compliance with pressure vessel regulations.

Appraisal Well

Industry

A well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.
