A hydraulic lifting device that grips steel strand cables to raise or lower extremely heavy loads incrementally. Subcontractors use strand jacks for heavy lifts on modules, bridges, and offshore structures. They are often mobilised by specialised rigging crews under a separate lifting subcontract.

Gas Rigs
IndustryDrilling rigs specifically configured to drill natural gas wells, requiring crews and equipment rated for high-pressure gas formations. For subcontractors, gas rigs often demand specialised certifications and H2S training. Work volumes typically follow natural gas commodity prices and seasonal heating demand.
Radial Conveyor
IndustryA belt conveyor mounted on a wheeled chassis that pivots in an arc to distribute bulk materials across a wide stockpile area. Subcontractors use them on aggregate, sand, and gravel sites to manage material placement without constant repositioning. They reduce manual labour and speed up site operations significantly.
Reservoir Characterization
IndustryThe process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Strait of Hormuz
IndustryA critical shipping chokepoint between Oman and Iran controlling roughly 20% of global oil flow. Disruptions here can spike material costs and delay equipment deliveries for subcontractors. Budget contingencies and procurement timelines should account for geopolitical risk in this corridor.
SAGD (Steam Assisted Gravity Drainage)
IndustryA heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.
Preconstruction
IndustryThe planning phase before field work begins, covering scope review, site assessments, and schedule alignment with the GC. Subcontractors are often engaged during this phase to provide pricing, labour forecasts, and constructability input. Early involvement can improve mobilisation timelines and reduce costly scope changes later.
