Liquefaction

How easily a design can be built efficiently using available crews, equipment, and site conditions. Poor constructability increases labour hours, rework, and cost overruns for subcontractors. Reviewing designs early helps field teams flag problems before mobilisation.

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.

The equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.

A structural failure where a concentrated load punches through a slab or foundation, creating a cone-shaped break. Subcontractors must watch for this risk when positioning heavy equipment on concrete pads or temporary platforms. Undetected, it can cause sudden equipment collapse and serious site liability.

A downhole tool that enlarges or stabilises a borehole during drilling operations. Subcontractors supplying or operating reamers must ensure proper tool specifications match formation conditions. Rental and mobilisation costs are typically scoped into the drilling services contract.

A system of electric cables or steam lines wrapped around pipes to prevent freezing or maintain process temperatures. Subcontractors are often hired to install, inspect, and commission these systems during turnarounds or new construction. Common in cold-climate facilities handling water lines, instrumentation, and process piping.

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.
