Incoming Inspection

A statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Field service contractors use EVA to assess project risk and plan contingency resources. It helps justify standby equipment costs and mobilisation buffers in contract negotiations.

Heat-resistant material installed inside furnaces, boilers, and process vessels to protect steel from extreme temperatures. Subcontractors are often hired for installation, inspection, and repair during turnarounds. Proper curing and dryout procedures are critical to avoid costly failures.

A corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.

In field logistics, a central staging location where crews, equipment, and materials are coordinated before deployment to remote job sites — the hub determines mobilisation routes, laydown areas, and logistical costs. In natural gas markets, a physical or virtual trading point where gas is bought, sold, and priced; hub pricing (AECO in Alberta, Henry Hub in the U.S.) directly affects contract rates and fuel costs for field service companies.

Underground systems that carry water, sewage, or other liquids, including water mains, storm drains, and sewer lines. Subcontractors must locate and mark these lines before any excavation to avoid costly damage or work stoppages. Wet utility work often requires specialised crews and municipal permits.

Status indicating a drilling rig has been formally stood down and all associated services are no longer required. For subcontractors, it triggers demobilisation, final invoice submission, and crew release. Contracts often specify notice periods and standby rates tied to this status.

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.
