Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Wet Utilities

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.

Related Terms

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.

Contingent Resources

Industry

Hydrocarbons discovered but not yet approved for development due to technical or commercial barriers. For subcontractors, these projects exist in planning stages but carry no guaranteed work orders. Mobilisation timelines remain uncertain until operator sanction is confirmed.

Scoping Period

Industry

A defined window where the prime contractor or operator outlines project requirements before awarding contracts. Subcontractors use this time to assess fit, prepare bids, and flag resource or equipment needs. Missing this window often means missing the contract opportunity entirely.

Facility Tie-in

Industry

The process of connecting new pipelines, equipment, or infrastructure to an existing operating facility. For subcontractors, tie-in work often requires strict hot-work permits and coordinated shutdowns with the operator. Scope can expand quickly, so clear change-order procedures are essential before mobilising.

Interconnection Agreement

Industry

A contract governing how a facility or system connects to a larger network, such as a pipeline or power grid. For subcontractors, it defines technical requirements and responsibilities during tie-in work. Non-compliance can trigger delays, penalties, or scope disputes.

Lifecycle-Based Approach

Industry

A method of planning services, maintenance, or contracts around the full lifespan of an asset or project phase. Subcontractors use it to align scopes of work, pricing, and resource deployment from mobilisation through decommissioning. This helps avoid scope gaps and supports longer-term service agreements.
