Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Trade Contractor

A specialised subcontractor hired to perform a specific skilled trade, such as electrical, welding, or pipefitting. They are typically engaged by a general contractor rather than the project owner directly. Trade contractors are responsible for supplying their own tools, crew, and trade-specific certifications.

Related Terms

Re-Export (crude)

Industry

Crude oil imported into one country and then shipped out to another without being refined domestically. For subcontractors, re-export activity drives short-term terminal, marine, and logistics work. Contract volumes can spike quickly, so crews and equipment must be mobilisation-ready.

Frac Flowback

Industry

The phase after hydraulic fracturing when water, sand, and hydrocarbons flow back to surface from the wellbore. Subcontractors are often mobilised quickly to manage fluid handling, testing, and disposal. Flowback work can be short-duration but requires crews and equipment on standby.

Concrete Gravity Structure

Industry

A massive concrete offshore platform held in place by its own weight rather than piles or anchors. Subcontractors working on CGS projects face complex multi-trade scopes in remote marine environments. Mobilisation, access logistics, and specialised certifications are critical planning factors.

Mud Logging

Industry

A well-site service that monitors drilling fluid returns to detect hydrocarbons and analyse formation data in real time. Subcontractors provide specialised technicians and instrumentation units for this work. It is commonly scoped as a standalone package within a drilling contract.

Hydrostatic Testing

Industry

A pressure integrity test where pipelines, vessels, or equipment are filled with water and pressurised to detect leaks or weaknesses. Subcontractors are often hired to perform or witness these tests before commissioning. Proper documentation is critical, as clients and regulators require certified test records.

Design-Build

Industry

A project delivery method where one contractor handles both engineering design and construction under a single contract. As a subcontractor, you may be brought in mid-scope with limited drawing sets, requiring flexibility. Scope creep risk is higher since designs are still evolving while field work begins.
