Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Pipeline Capacity

The maximum volume of oil, gas, or fluid a pipeline can transport over a given period. For subcontractors, capacity constraints directly affect project scheduling and the urgency of inspection, maintenance, and tie-in work. Operators may fast-track field service contracts when pipelines are running near capacity limits.

Related Terms

Field Ticket

Industry

A document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.

Refined Products Pipeline

Industry

A pipeline system that transports processed petroleum products — such as gasoline, diesel, and jet fuel — from refineries to distribution terminals. Subcontractors are commonly mobilised for inspection, maintenance, and integrity work on these lines. Strict product contamination and safety protocols apply, requiring up-to-date certifications.

Preconstruction

Industry

The planning phase before field work begins, covering scope review, site assessments, and schedule alignment with the GC. Subcontractors are often engaged during this phase to provide pricing, labour forecasts, and constructability input. Early involvement can improve mobilisation timelines and reduce costly scope changes later.

Paid-Up Lease

Industry

A lease where all rental payments are made upfront, with no ongoing delay rentals required to keep it active. For subcontractors, this signals stable, long-term site access without mid-contract tenure disruptions. Work scopes on paid-up leases are less likely to be suspended due to expiry pressure.

Prefabrication

Industry

The assembly of piping, structural, or mechanical components in a controlled shop environment before site installation. Subcontractors often bid prefab scope separately from field installation work. It can reduce on-site labour hours and shorten project schedules.

Upstream Tie-in

Industry

A connection point where new pipeline or equipment is integrated into an existing live system closer to the wellhead or source. For subcontractors, this work typically requires strict hot-work permits and precise scheduling around production shutdowns. Delays at tie-in points directly impact your crew's standby time and invoice milestones.
