A delivery model where one firm handles both project management and general contracting. For subcontractors, this means a single point of contact manages your scope, schedule, and contract. Expect tighter coordination requirements and change order oversight from the CM/GC.

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds, pipelines, and structural components for defects. It produces detailed cross-sectional images without cutting or damaging the material. Subcontractors offering PAUT services typically require certified Level II or III technicians and specialised portable equipment.

The phase of oil and gas well development after drilling is finished, encompassing the work required to prepare a well for production — including perforating, fracturing, and installing wellhead equipment. For subcontractors, completions represent a concentrated burst of high-demand field work where specialised crews, equipment, and services are mobilised under tight timelines.

The process of producing and managing saltwater solutions used in well completion, workover, and drilling operations. Subcontractors may be engaged for fluid handling, storage, transport, or disposal services. Scope can vary widely, so confirm fluid specifications and disposal requirements before mobilising.

A company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.
