A mobile offshore drilling rig with retractable legs that jack down to the seabed, elevating the platform above water. Subcontractors mobilising to a jackup must account for offshore certification, marine logistics, and platform-specific access requirements.
Jackup
Related Terms
Pumping Station
IndustryA facility that moves oil, gas, or water through a pipeline using mechanical pumps. Subcontractors are frequently mobilised here for maintenance, inspection, and equipment upgrades. Work scope often includes rotating equipment, instrumentation, and civil trades.
Tieback
IndustryA structural anchor or connection point used to secure equipment, pipelines, or wellheads back to an existing infrastructure system, commonly referenced in subcontractor scopes of work when connecting new installations to live or existing lines. Subcontractors should confirm tieback specifications and isolation procedures clearly in their contracts, as this work often involves elevated risk and may require additional certifications or permits.
Run Schedule
IndustryA timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.
GWD (Getting Work Done)
IndustryA safety and compliance management system used by some operators to pre-qualify and manage contractors working on their sites.
Completion Crews
IndustrySpecialised teams mobilised after drilling to prepare a well for production. For subcontractors, they represent a distinct scope of work with separate contracts, timelines, and crew requirements. Demand is tied directly to operator completion schedules, affecting short-notice mobilisation and billing cycles.
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.
