Booster Compressor

The process of confirming that the work described in a contract matches actual field conditions before mobilising. Subcontractors use it to catch scope gaps that could lead to unpaid extras. Undocumented changes discovered on-site are easier to dispute without prior validation.

A monitoring technology that uses fibre-optic cables as continuous sensors along pipelines, wellbores, or structures. It detects temperature, strain, and acoustic changes across kilometres of cable in real time. Subcontractors may be hired to install, splice, or maintain these cable systems during construction or integrity projects.

A surface preparation method using focused laser energy to remove rust, coatings, or contaminants from metal. Subcontractors use it as a cleaner alternative to sandblasting on pipelines and structural steel. It reduces waste disposal costs and meets strict environmental site requirements.

An industry classification covering subcontractors who provide services to upstream oil and gas producers without extracting resources themselves. This includes well servicing, site prep, equipment rental, and pipeline support. Most field service companies in oil and gas fall under this category for tax and regulatory purposes.

High-pressure water jetting used to clean, strip, or cut surfaces on industrial equipment and structures. Subcontractors typically require specialised certification and equipment to bid this scope. It is common in tank cleaning, pipeline maintenance, and surface prep work.

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.
