The process of safely shutting down and dismantling oil and gas infrastructure at end-of-life. For subcontractors, it generates significant work in removal, remediation, and site restoration. Scopes often include demolition, equipment salvage, and regulatory closeout tasks.
Decommissioning
Related Terms
Network Interconnection
IndustryThe linking of separate communication systems so field crews, dispatch, and client sites can share data in real time. For subcontractors, this enables job updates, timesheets, and safety reports to flow between systems without manual re-entry. Reliable interconnection reduces billing delays and keeps remote sites aligned with head office.
Gigafactory
IndustryA large-scale manufacturing facility producing batteries or energy components, often for EV or renewable projects. These sites generate major subcontracting opportunities in electrical, civil, and mechanical trades. Expect large crew mobilisations, tight schedules, and industrial construction workflows.
Reactive Maintenance
IndustryRepair work performed after equipment has already failed or broken down. Subcontractors are often mobilised on short notice, commanding premium rates. Tight timelines increase crew fatigue and safety risks on site.
ROV (Remotely Operated Vehicle)
IndustryAn 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.
Rig Count
IndustryThe number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.
Strand Jack
IndustryA hydraulic lifting device that grips steel strand cables to raise or lower extremely heavy loads incrementally. Subcontractors use strand jacks for heavy lifts on modules, bridges, and offshore structures. They are often mobilised by specialised rigging crews under a separate lifting subcontract.
