Oil & Gas Industry

Protecting Integrity Across the Hydrocarbon Asset Lifecycle

Global Alliance Register supports oil and gas operators, EPC contractors, developers, manufacturers, investors and asset owners with technical assurance, project surveillance, inspection, testing, certification and asset-integrity services across upstream, midstream and downstream operations.

Oil and gas assets operate under demanding pressure, temperature, process and environmental conditions. Quality failures can affect containment, availability, project schedule, production performance and long-term asset reliability.

Global Alliance Register helps clients control these risks from engineering and procurement through fabrication, construction, commissioning, operation and life extension.

Through our international network and cooperation with qualified and accredited testing, inspection and certification organizations, GAR can coordinate multi-country assignments across manufacturing facilities, fabrication yards, project sites, pipelines and operating plants.
