LOI (Letter of Intent)

A measure of annual production or throughput capacity at LNG, mining, or pipeline facilities. Subcontractors use it to gauge project scale and estimate long-term scope of maintenance or construction work. Higher MMtpa ratings typically signal larger crews, longer contracts, and more equipment requirements.

A project with permits, funding, and engineering approved, allowing field work to begin immediately. For subcontractors, it signals that mobilisation and contract awards are imminent. Pursuing shovel-ready work reduces the risk of scoping delays eating into your margins.

Any work or structure located below the finished ground surface, such as buried pipelines, foundations, or conduits. Subcontractors must account for added costs like shoring, dewatering, and confined space compliance. Scope changes below-grade often trigger change orders due to unforeseen soil or utility conditions.

An open-framework steel crane arm made of welded triangular sections, used for heavy lifts on oil and gas or construction sites. Subcontractors must verify lift plans and operator certifications before mobilising lattice boom cranes. Daily rates and rigging crew requirements are typically higher than hydraulic boom alternatives.

A statistical measure that projects a short-term activity figure into a full-year estimate, removing seasonal fluctuations. Clients and prime contractors use SAAR data to forecast project pipelines and award subcontracts. Tracking SAAR trends helps field service companies anticipate hiring surges or slowdowns before they hit.

A partial greenlight from a client authorising subcontractors to begin limited, specific work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities only. Scope and spending are strictly capped, so track your costs carefully to avoid unauthorised overruns.

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.
