FPSO (Floating Production, Storage and Offloading Unit)

A large-diameter transmission pipeline moving oil, gas, or NGLs over hundreds or thousands of kilometres between facilities. For subcontractors, these projects involve extended mobilisation, multi-phase scopes, and strict regulatory oversight. Work typically includes welding, coating, hydrotesting, and right-of-way clearing across varied terrain.

A measure of natural gas production or pipeline throughput volume. Higher BCF/d figures on a project typically signal larger-scale operations requiring more field crews and equipment. Subcontractors can use this metric to gauge the scope and duration of potential work.

A strong, flexible cast iron alloy used in pipes, fittings, and valves on oil and gas and construction sites. It resists cracking under pressure, making it common in water, gas, and slurry line installations. Subcontractors should confirm material specs before procurement, as ductile iron has specific handling and joining requirements.

A project delivery model where one firm manages engineering, procurement, and construction on the owner's behalf. Subcontractors are hired directly by the owner, not the EPCM firm. Understanding this structure clarifies your contract chain, payment authority, and site reporting lines.

Natural gas composed almost entirely of methane, with minimal liquid hydrocarbons. Subcontractors working dry gas sites face simpler handling requirements but often leaner margins than wet gas projects. Expect lighter equipment specs and fewer fluid management scopes.

The formal handover point where ownership or responsibility for a measured quantity of oil, gas, or other product moves from one party to another — typically triggering billing, invoicing, or contractual obligations for subcontractors involved in metering, transport, or handling operations. Field service crews working custody transfer points must ensure measurements are accurate and fully documented, as discrepancies can directly affect client invoices and liability.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
