Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Closed-Loop Cooling

A system that recirculates coolant through equipment without discharging it to the environment. Subcontractors must maintain leak-free connections and monitor fluid levels during installation and servicing. Improper handling can trigger environmental compliance violations on site.

Related Terms

Progressive Design-Build

Industry

A project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.

Mmtpa (million Metric Tons Per Annum)

Industry

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.

Integrated Project Delivery (ipd)

Industry

A project delivery model where owners, contractors, and subcontractors share contracts, risks, and rewards from early design through completion. Subcontractors are brought in earlier than traditional models, giving more input on planning and scheduling. Compensation is often tied to collective project outcomes rather than individual scope performance.

JIP (Joint-industry Project)

Industry

A cost-sharing initiative where multiple operators or companies fund research, technology development, or industry challenges together. For subcontractors, JIPs can open doors to new contracts, but procurement processes are often slow and heavily governed. Understanding which operators are involved helps you identify who holds the real budget authority.

Carbonate Formation

Industry

A type of subsurface rock layer—primarily limestone or dolomite—that subcontractors may encounter during drilling, completions, or civil excavation work, often requiring specialised equipment, bit selections, or modified drilling programmes due to its hardness and tendency to cause lost circulation events.

SMR (Small Modular Reactor)

Industry

A compact, factory-built nuclear power unit used to generate on-site electricity for remote industrial facilities and resource projects. For subcontractors, SMR sites represent emerging work in civil, electrical, and mechanical trades. Expect strict federal nuclear safety compliance requirements affecting worker certifications and site access.
