About CompEx

CompEx safety and competency

For nearly 30 years the CompEx Scheme has been the recognised global competency scheme for the safety of workers in the oil, gas and chemical industries. We share four core values with our parent company, the JTL Group which underpins the CompEx ethos.


We are effective, skilled and serious about what we do.


We believe in being honest and fair and delivering on our promise.


We treat our customers, stakeholders and staff courteously, honestly and fairly.


We respond to our customers and the sector’s expectations and provide a great experience for all.

CompEx history

The CompEx Scheme is the result of Lord Cullen’s investigation into the Piper Alpha tragedy, which killed 167 oil rig workers on 6th July 1988 off the coast of Aberdeen. This tragic event is considered to be the world’s deadliest oil rig accident. Lord Cullen’s report led to more than 100 recommendations that transformed the North Sea oil and gas industry into a global leader of safety within these hazardous environments.

In 1993, the CompEx Scheme was launched and has seen phenomenal success since the first centre was opened in 1994. After 10 years, the scheme celebrated the milestone of certificating 10,000 candidates for Gas and Vapour. Now that figure has risen to over 100,000 candidate certificates, a continued success that ensures a safer future for many thousands of workers around the world.

On 22nd November 2018, CompEx was awarded the Association for Petroleum and Explosives Administration (APEA) Milestone Award at the APEA Awards for celebrating 25 years of increasing safety in explosive atmosphere workplaces.
