Fractionating Tower

The process of excavating a vertical or near-vertical tunnel from surface down to an underground work area. Subcontractors are often engaged for specialised tasks like lining, hoisting, or ground support during this phase. It is common in mining, utility, and heavy civil construction projects.

A well with significant technical complexity, cost, or strategic value to the operator. For subcontractors, these projects typically involve stricter oversight, specialised equipment, and higher performance expectations. Mobilisation windows and crew qualifications are often scrutinised more closely.

Underground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.

A field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.

An unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.
