Industry Glossary Term

Thermal Resource Fleet

A subcontractor's collection of heat-generating equipment, such as steam generators, line heaters, and freeze protection units. These assets are mobilised for cold-weather operations, pipeline conditioning, or process heating on oil and gas sites. Fleet size directly affects a subcontractor's capacity to bid on thermal service contracts.

Related Terms

Mini Crawler Crane

Industry

A compact, track-mounted crane used for lifting in confined or access-restricted job sites. Subcontractors rely on them where standard cranes cannot manoeuvre. Common in industrial shutdowns, pipeline work, and tight construction corridors.

Pipeline Integrity

Industry

The ongoing process of ensuring pipelines remain safe, structurally sound, and compliant with regulatory standards. Subcontractors are frequently hired for inspection, maintenance, and repair work tied to integrity programmes. Scopes can include ILI (Inline Inspection), coating repairs, hydrotesting, and fitness-for-service assessments.

Rig Count

Industry

The number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.

BHA (Bottom Hole Assembly)

Industry

The collection of drilling tools and equipment at the bottom of the drill string, including the drill bit, drill collars, stabilizers, and downhole motors. For drilling subcontractors, BHA configuration directly impacts drilling performance, tool wear rates, and operational efficiency.

Prefabrication

Industry

The assembly of piping, structural, or mechanical components in a controlled shop environment before site installation. Subcontractors often bid prefab scope separately from field installation work. It can reduce on-site labour hours and shorten project schedules.

Offtake Agreement

Industry

A long-term contract where a buyer commits to purchasing a set volume of product from a producer. For subcontractors, these agreements signal stable, ongoing site activity and sustained demand for field services. They often underpin project financing, making worksites more financially secure for service providers.
