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.

Related Terms
Re-Export (crude)
IndustryCrude oil imported into one country and then shipped out to another without being refined domestically. For subcontractors, re-export activity drives short-term terminal, marine, and logistics work. Contract volumes can spike quickly, so crews and equipment must be mobilisation-ready.
Reinforcing Bar (rebar)
IndustrySteel bars embedded in concrete to add tensile strength in foundations, structures, and infrastructure builds. Subcontractors handling rebar must account for material costs, placement labour, and tie wire in their bids. Improper installation can trigger costly rework and inspection failures.
Voluntary Cuts
IndustryAgreed reductions in oil production by member nations, typically OPEC (Organization of the Petroleum Exporting Countries) members, to stabilise prices. For subcontractors, these cuts often trigger project deferrals, reduced scope, and slower mobilisation schedules. Budget freezes from operators frequently follow, directly impacting field service award timelines.
Work Order
IndustryA formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.
Sand Management
IndustryThe process of controlling, monitoring, and removing sand produced alongside oil and gas to protect wellbore equipment and surface facilities. Subcontractors may be hired to install sand screens, separators, or erosion monitoring systems. Poor sand management accelerates equipment wear and increases maintenance callouts.
Geosteering
IndustryThe real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.
