UK offshoreThe 2022 rename, explained
Same certificate, new name. Oil & Gas UK became Offshore Energies UK in February 2022 — what changed, what didn’t, whether older OGUK certificates are still valid, and what to write on your CV.

How these guides are written
Each guide is grounded in publicly-documented information from the issuing body (OPITO, IMO flag states, Australian state regulators) and verified training providers. Validity periods, course modules, and unit codes are quoted directly from the issuing authority where possible.
Certification requirements change. Always verify with your specific operator, training provider, or regulator before booking a course or claiming compliance. If you spot something out of date, tell us at support@certvaultapp.com.
