An engine or generator that runs on two fuel sources, typically diesel and natural gas, allowing switching based on availability or cost. Common on remote job sites where field crews manage fuel supply logistics. Subcontractors may need certified technicians and specific maintenance protocols to operate this equipment.
Dual-Fuel System

Feasibility Study
IndustryA pre-project assessment that evaluates whether a scope of work is technically and financially viable. For subcontractors, it signals early-stage work that may lead to awarded contracts. Participating in feasibility work can position your company for the larger project bid.
Voluntary Cuts
IndustryAgreed reductions in oil production by member nations, typically OPEC (Organization of the Petroleum Exporting Countries) members, to stabilise prices. For subcontractors, these cuts often trigger project deferrals, reduced scope, and slower mobilisation schedules. Budget freezes from operators frequently follow, directly impacting field service award timelines.
PCP (Progressive Cavity Pump)
IndustryA rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.
Transmission Planning
IndustryThe long-term process of designing and expanding power grid infrastructure to meet future energy demand. For subcontractors, it drives project pipelines for line construction, right-of-way clearing, and equipment installation. Winning transmission work often requires early engagement with utilities and grid operators.
Cavern Storage
IndustryUnderground 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.
Modular Construction
IndustryA build method where structures are assembled from prefabricated units manufactured offsite, then transported and installed on location. Subcontractors are often scoped for site prep, mechanical tie-ins, or installation crews rather than full builds. Work tends to come in concentrated, short-duration packages tied to delivery schedules.
