The TIGs offer guidance to ONR inspectors on what licensees’ arrangements should include to meet the requirements of the Licence Conditions. This ensures a consistent approach.
While primarily written for inspectors, these guides also give licensees and the wider public insight into ONR’s expectations for how safety and compliance should be managed.
