Upgrading or modifying existing equipment to meet new specs, safety standards, or operational requirements. Subcontractors are often hired specifically for retrofit scopes on aging infrastructure. Work may require specialised certifications and careful coordination with the client's existing systems.

STACK (Sooner Trend Anadarko Basin Canadian and Kingfisher)
IndustryA prolific multi-zone oil and gas play in central Oklahoma covering Canadian and Kingfisher counties. Subcontractors active here support high-density horizontal drilling and completions work. Mobilisation demand can spike quickly, so maintaining local crew and equipment availability is critical.
Combined-Cycle Gas Plant
IndustryA power generation facility that uses both gas turbines and steam turbines to maximise efficiency. For subcontractors, these sites involve complex, multi-discipline scopes across mechanical, electrical, and instrumentation trades. Outage and commissioning work is highly scheduled, requiring precise crew coordination and fast mobilisation.
Design-Bid-Build
IndustryA project delivery method where design is completed before subcontractors are invited to bid. Scope is fully defined upfront, reducing ambiguity in your quote. Common in construction; less flexible once awarded, so price your bid carefully.
Interconnection
IndustryThe physical linking of two or more systems, pipelines, or electrical networks at a shared tie-in point. For subcontractors, interconnection work often requires strict coordination with the prime contractor and operator. Scope boundaries and handoff responsibilities must be clearly defined in your subcontract.
Capital Maintenance Agreement
IndustryA long-term contract where a subcontractor provides scheduled upkeep and repairs on a client's major assets or facilities. Work scopes, pricing, and mobilisation terms are typically locked in advance. These agreements offer subcontractors predictable revenue but may limit flexibility to take on other work.
OFS (Oilfield Field Services)
IndustryThe sector of companies and subcontractors that provide specialised labour, equipment, and technical services to oil and gas operators. This includes drilling, completions, maintenance, and production support work. Most field subcontractors operate within the OFS sector, working under Tier 1 service companies or directly for operators.
