A large-scale battery installation that stores and dispatches electrical power on remote or off-grid job sites. Subcontractors may be hired to install, commission, or maintain these units alongside diesel generators or solar arrays. Familiarity with high-voltage systems and OEM safety protocols is typically required.
BESS (Battery Energy Storage System)
Related Terms
Emulsion Breakers
IndustryChemical additives used in oil and gas processing to separate water from crude oil in production streams. Subcontractors handling fluid management or chemical injection skids are often responsible for their application and dosing. Proper handling requires WHMIS (Workplace Hazardous Materials Information System) compliance and PPE protocols.
Ip120 (initial Production 120-Day Rate)
IndustryThe average daily production output of a new well over its first 120 days. Operators use this benchmark to schedule and extend field service contracts. Strong IP120 results often trigger follow-on work for completions and production crews.
Drill-And-Blast
IndustryA ground excavation method where holes are drilled into rock, then loaded with explosives and detonated. Subcontractors on these scopes typically require certified blasters and strict compliance with provincial explosives regulations. Expect tight sequencing with other trades and potential site shutdowns during blast windows.
Shallow-Water
IndustryOffshore operating zones typically under 500 feet of water depth. For subcontractors, these sites use jack-up rigs and barges rather than deepwater vessels. Crew access, equipment requirements, and mobilisation costs differ significantly from deepwater scopes.
Fractionating Tower
IndustryA large vertical vessel at refineries and gas plants that separates hydrocarbons into usable products like propane, naphtha, and diesel. Subcontractors are frequently called in for turnaround maintenance, inspection, and refractory work on these units. Access planning and confined space protocols are critical for any scope inside the tower.
Oil-Directed Drilling
IndustryA drilling programme targeting oil reservoirs rather than natural gas. Subcontractors can expect higher rig activity and longer campaign durations in regions where oil prices justify development. Demand for completions, fluid hauling, and wellsite services typically rises during oil-directed cycles.
