Verification & assurance consultants to the global energy industry

Douglas Hay founded ADC in 1985 to challenge what was deemed acceptable in the offshore industry.  His vision was to make the industry safer, cleaner and more efficient by providing independent assurance to Energy companies hiring rigs and vessels.

Douglas’ vision remains at the heart of what we do and is applied to rigs within the Oil and Gas sector, Geothermal or CCUS, in addition to the specialist vessels used to build wind farms of the future. Today our team of over 60 professionals are committed to driving safety, operational and environmental performance – supporting the majority of the world’s leading Energy companies.

Challenging the status Quo for over 35 years
