Industry Glossary Term

EVA (Extreme Value Analysis)

A statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Field service contractors use EVA to assess project risk and plan contingency resources. It helps justify standby equipment costs and mobilisation buffers in contract negotiations.

Related Terms

Membrane Separation

Industry

A filtration process that uses semi-permeable membranes to separate gases or liquids by molecular size or pressure. Common in natural gas processing and produced water treatment on field sites. Subcontractors may install, inspect, or maintain membrane units as part of facility service scopes.

Heavy Civil

Industry

Large-scale infrastructure construction involving earthworks, bridges, roads, and foundations. Subcontractors in this sector typically supply specialised equipment, civil crews, or concrete services. Contracts are often high-value but require significant bonding and insurance capacity.

Phased Array Ut (phased Array Ultrasonic Testing)

Industry

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds and materials for defects. It replaces traditional radiography on many pipeline and pressure vessel jobs. Subcontractors offering PAUT services often command higher rates and qualify for more specialised scopes.

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.

FFS (Fitness-for-service)

Industry

A structured engineering assessment that determines whether ageing or damaged equipment is safe to keep operating. Subcontractors are often hired to collect inspection data, run integrity tests, or execute repairs recommended by FFS evaluations. Understanding FFS scope helps field crews prioritise work orders and meet client fitness thresholds before returning assets to service.

FRP (Fibre-reinforced Polymer)

Industry

A lightweight, corrosion-resistant composite material used in piping, grating, and structural components on oilfield and construction sites. Subcontractors encounter FRP in offshore platforms, chemical plants, and water treatment facilities. It requires specialised handling and cutting procedures to avoid hazardous dust exposure.
