Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Turnkey

A contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.

Related Terms

Full Displacement Pile

Industry

A foundation pile driven or screwed into soil without removing material, pushing ground laterally to create a tight fit. Common in oil and gas facility and construction site foundations. Subcontractors should confirm soil displacement specs early, as ground conditions directly affect equipment selection and crew scheduling.

Plugged and Abandoned

Industry

A well that has been permanently sealed with cement and decommissioned. For subcontractors, P&A work is a distinct scope involving abandonment crews, specialised equipment, and regulatory sign-off. Invoicing and mobilisation terms should be confirmed before work begins, as these projects are often time-sensitive.

Tidal-Water Export Terminal

Industry

A coastal or estuary facility where bulk commodities like LNG or crude oil are loaded onto marine vessels for export. Water depth fluctuates with tides, affecting vessel scheduling and your crew's access windows. Subcontractors must plan shifts and equipment mobilisation around tide tables and vessel berthing schedules.

Balance-Of-Plant

Industry

All supporting systems and infrastructure outside the primary process equipment, such as electrical, piping, HVAC, and civil works. For subcontractors, BOP (Balance-of-Plant) scope often represents the bulk of awarded field labour. Knowing what falls under BOP helps avoid scope gaps and missed bid items.

Compression Station

Industry

A facility that boosts natural gas pressure to move it through pipelines over long distances. Subcontractors are frequently mobilised here for maintenance, mechanical work, and equipment inspections. These sites often require specific safety certifications and site orientations before work begins.

Sole-Source Contract

Industry

A contract awarded directly to one subcontractor without a competitive bidding process. Operators use this when your firm has specialised expertise, proprietary equipment, or an urgent mobilisation is required. It can mean faster contract execution but often comes with tighter scope and pricing scrutiny.
