Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Grid Congestion

Grid congestion occurs when electrical transmission lines carry more power than they can handle, causing bottlenecks. For subcontractors, it can delay grid-tied project energisation and push back commissioning milestones. Remote site work may shift to temporary generation until congestion is resolved.

Related Terms

Infill Drilling

Industry

Drilling new wells between existing producers to recover bypassed reserves in a developed field. For subcontractors, it means shorter mobilisation windows and back-to-back well programmes. Expect high crew utilisation but tight scheduling with little downtime between jobs.

Life Extension

Industry

A formal process that prolongs the operational life of ageing assets beyond their original design lifespan. For subcontractors, it often means increased inspection, repair, and maintenance scopes. Expect stricter compliance requirements and potential for longer-term service contracts.

Voluntary Cuts

Industry

Agreed 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.

Rig Release

Industry

The formal point when a drilling rig is demobilised and the operator ends the rig contract. For subcontractors, it signals the close of associated scopes of work and triggers final invoicing. Crew demob, equipment retrieval, and close-out documentation should begin immediately.

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.

Preventive Maintenance

Industry

Scheduled servicing of equipment before failures occur, reducing costly downtime on job sites. Subcontractors are often contracted specifically to perform PM work on client assets. Documented PM records also support compliance audits and contract renewals.
