A self-propelled vessel equipped with a drilling rig used for offshore exploration and production in deepwater locations, which subcontractors may be mobilised to for specialised services such as equipment maintenance, inspection, or crew support under strict offshore safety and logistical requirements.
Drillship
Related Terms
Cook Inlet
IndustryA major oil and gas producing basin in southcentral Alaska with active offshore and onshore operations. Subcontractors working here face remote logistics, tidal extremes, and strict environmental regulations. Mobilisation costs and specialised marine requirements significantly affect bid pricing.
Hydrovac
IndustryA truck-mounted unit that uses pressurised water and a vacuum system to excavate soil safely around buried utilities. Subcontractors are frequently hired for hydrovac work on pipeline, civil, and utility projects. It is preferred over mechanical digging in areas with high strike risk.
Onshore Basin
IndustryA land-based sedimentary region where oil and gas exploration and production activity is concentrated. For subcontractors, basins define your likely work zones, client base, and mobilisation distances. Key Canadian examples include the Western Canada Sedimentary Basin (WCSB).
IMR (Inspection, Maintenance, and Repair)
IndustryA category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.
Physical Oil Price
IndustryThe actual market price paid for real barrels of oil delivered at a specific location, as opposed to futures contract prices. For subcontractors, client budgets and contract award activity closely track physical oil prices. When physical prices drop, project deferrals and rate pressure often follow quickly.
Integrated Project Delivery (ipd)
IndustryA project delivery model where owners, contractors, and subcontractors share contracts, risks, and rewards from early design through completion. Subcontractors are brought in earlier than traditional models, giving more input on planning and scheduling. Compensation is often tied to collective project outcomes rather than individual scope performance.
