Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Load Growth

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

Related Terms

Fumigation (engine)

Industry

A method of injecting a secondary fuel, such as natural gas or propane, into a diesel engine's air intake to supplement combustion. It reduces fuel costs and emissions on long-running field equipment. Subcontractors should verify fumigation setups meet emissions compliance requirements in their operating jurisdiction.

Derivative Goods

Industry

Products created by processing or transforming raw materials supplied under a contract, such as fabricated components or treated fluids. Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.

Sanctioned Field

Industry

A field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.

Hydrostatic Testing

Industry

A pressure integrity test where pipelines, vessels, or equipment are filled with water and pressurised to detect leaks or weaknesses. Subcontractors are often hired to perform or witness these tests before commissioning. Proper documentation is critical, as clients and regulators require certified test records.

Schedule Compliance

Industry

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

Secondary Stress

Industry

Indirect mechanical stress that develops in structures or piping due to thermal expansion, settlement, or equipment movement. Unlike primary stress, it isn't caused by direct applied loads. Subcontractors must account for it during installation and inspection to avoid material fatigue and warranty disputes.
