Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Call for Interest

A formal notice from an operator or prime contractor inviting subcontractors to express interest in upcoming work. It is not a binding tender but helps owners build a qualified vendor list. Responding early can position your company for the actual bid process.

Related Terms

Viaduct

Industry

A long elevated bridge structure carrying roads or pipelines over valleys, water, or rough terrain. Subcontractors working near viaducts must account for access restrictions and specialised rigging requirements. Inspection and maintenance contracts on viaducts often require working-at-heights certification.

Commercial Operations

Industry

The point when a facility or project officially begins generating revenue and is fully handed over from construction to production. For subcontractors, this milestone often triggers final billing, contract closeout, and demobilisation. Work orders and scopes tied to commissioning typically end at this date.

Mwh (megawatt-Hour)

Industry

A unit measuring one megawatt of electrical power consumed or produced over one hour. Subcontractors encounter MWh when billing for generator rentals, temporary power supply, or energy-intensive equipment on remote sites. It also appears in green energy projects where field crews install or service solar, wind, or battery storage systems.

Combined Cycle

Industry

A power generation setup where waste heat from a gas turbine is reused to produce additional electricity via a steam turbine. Subcontractors working these facilities must be prepared for more complex systems and stricter safety protocols. Maintenance scopes are typically broader, covering both turbine types.

Critical Minerals

Industry

Minerals deemed essential to national economies and energy transition, such as lithium, cobalt, and rare earths. Extraction and processing projects for these materials are driving significant new field service demand across Canada. Subcontractors with mining or remote site experience are well-positioned to pursue this growing work.

Curtailment

Industry

A reduction or suspension of oil, gas, or construction operations ordered by the operator or regulator. For subcontractors, curtailment often means standby, demobilisation, or reduced scope with little notice. Review your contract carefully for curtailment clauses that affect payment and mobilisation costs.
