Industry Glossary Term

SSC (Sulfide Stress Cracking)

A form of metal cracking caused by hydrogen sulphide (H₂S) exposure under stress, common in sour gas environments. Subcontractors must use SSC-resistant materials and equipment rated for sour service on these sites. Non-compliant tools or components can fail catastrophically, creating serious liability and safety risks.

Related Terms

Tieback

Industry

A structural anchor or connection point used to secure equipment, pipelines, or wellheads back to an existing infrastructure system, commonly referenced in subcontractor scopes of work when connecting new installations to live or existing lines. Subcontractors should confirm tieback specifications and isolation procedures clearly in their contracts, as this work often involves elevated risk and may require additional certifications or permits.

Pump Station

Industry

A facility that moves oil, gas, or water through a pipeline using mechanical pumps. Subcontractors are frequently mobilised to pump stations for maintenance, inspection, and equipment servicing work. These sites often require specific safety certifications and site orientations before work begins.

Wellpad

Industry

A prepared, levelled site where one or more oil or gas wells are drilled and completed. Subcontractors often mobilise to a wellpad for multi-well scopes, making it a key unit for planning labour and equipment. Pad size and well count directly affect job duration and invoicing cycles.

Microgrid

Industry

A small, self-contained power system that operates independently from the main utility grid. Subcontractors working remote sites often rely on microgrids for consistent site power. Knowing the local power setup affects equipment compatibility and fuel logistics planning.

RAP (Reclaimed Asphalt Pavement)

Industry

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.

Development Sanction

Industry

The formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.
