The phase where installed equipment and systems are connected to utilities, instrumentation, and process lines. For subcontractors, hookup work often follows construction and represents a distinct, billable scope. Crews must coordinate closely with commissioning teams to avoid delays.
Hookup
Related Terms
Marine Infrastructure
IndustryOffshore and coastal structures such as platforms, jetties, pipelines, and subsea systems where field work is performed. Subcontractors must hold marine-specific certifications and follow offshore safety protocols. Mobilisation costs and logistics are typically higher than onshore projects.
Prospective Interval
IndustryA rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.
Directional Drilling
IndustryA drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.
Brent Crude
IndustryA globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.
Field Ticket
IndustryA document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.
Spot Work
IndustryShort-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.
