Alliance Construction Contract

A moored vessel used solely to store crude oil or LNG offshore, without production capabilities. Subcontractors are engaged for inspection, maintenance, and marine support work aboard these assets. Mobilisation logistics and offshore safety certifications are typically required before access is granted.

A standardised production metric that converts all hydrocarbons—oil, gas, and NGLs—into a single daily output figure. Operators use BOED to size contracts and scope field service requirements. Higher BOED rates typically mean larger crew needs, more equipment, and increased service volumes for subcontractors.

The heaviest category of commercial trucks, rated at over 33,001 lbs gross vehicle weight. Common in oil and gas field work for hauling heavy equipment, frac sand, and pipe. Operators require a Class 1 licence in Canada.

Describes any task, system, or equipment whose failure would halt operations or create serious safety risks. For subcontractors, mission critical work often carries stricter response times, higher liability, and tighter documentation requirements.

Building projects covering commercial, industrial, and institutional structures rather than homes. For subcontractors, this includes work on warehouses, refineries, offices, and infrastructure. These projects often involve larger contracts, stricter compliance requirements, and longer payment cycles.

A complete processing system that cools natural gas into liquid LNG (Liquefied Natural Gas) for storage and transport. Each train is a major construction and maintenance scope, often requiring large, specialised subcontractor workforces. Shutdowns and turnarounds on these units are high-value contracts with strict schedule demands.

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.

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.
