Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Jackup

A mobile offshore drilling rig with retractable legs that jack down to the seabed, elevating the platform above water. Subcontractors mobilising to a jackup must account for offshore certification, marine logistics, and platform-specific access requirements.

Related Terms

Decommissioning

Industry

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.

Parcel

Industry

A defined section of land or a lease area assigned to a specific project or operator. Subcontractors may be scoped and mobilised by parcel, affecting billing boundaries and crew deployment zones.

Reactive Maintenance

Industry

Repair 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.

Early-Works

Industry

Preliminary site preparation activities awarded before a project's main contract is finalised. For subcontractors, this means mobilising early—often under a letter of intent—to handle clearing, grading, or utility work. Scope and payment terms can be limited, so review your agreement carefully before committing resources.

Dispatchable Power

Industry

Power generation that can be turned on or off on demand, unlike solar or wind. For field crews, this means reliable site power for tools, lighting, and equipment regardless of weather. Generators and diesel units are common dispatchable power sources on remote job sites.

Collaborative Delivery

Industry

A project model where owners, general contractors, and subcontractors share responsibilities, risks, and rewards from the outset. Subcontractors are brought in early to provide input on scheduling, costing, and field execution. This approach reduces change orders and improves coordination across trades and disciplines.
