Viaduct

A formal document issued by an operator or general contractor inviting subcontractors to bid on a scope of work. It outlines project requirements, timelines, and evaluation criteria. Responding competitively to RFPs is a primary way field service companies win new contracts.

A surface facility that receives, separates, measures, and stores crude oil from multiple wells. Subcontractors frequently work at batteries for maintenance, instrumentation, and tank servicing. It is a common site for ongoing field service scopes.

Factory-manufactured concrete sections delivered to site ready for installation. Subcontractors handle lifting, positioning, and anchoring rather than forming and pouring. Speeds up schedules but requires certified rigging crews and heavy lift equipment.

A Canadian-designed nuclear reactor that uses heavy water as a moderator and coolant. Subcontractors working on maintenance or upgrades face strict nuclear regulatory compliance and specialised certification requirements. Expect rigorous site access controls, radiation safety training, and detailed documentation standards.

A watertight steel or concrete structure used to support foundations in offshore or waterlogged environments. Subcontractors may be scoped to install, inspect, or perform maintenance work on caissons. Access and confined space protocols often apply.

A pipeline system that transports processed petroleum products — such as gasoline, diesel, and jet fuel — from refineries to distribution terminals. Subcontractors are commonly mobilised for inspection, maintenance, and integrity work on these lines. Strict product contamination and safety protocols apply, requiring up-to-date certifications.
