2023 Joint US and European DiERS User Group Meeting

Joint US and European Workshop on Process and Plant Safety

2023 Joint DiERS Meeting

Another successful get-together of the US & European DiERS community

The 2023 Joint Diers User Group Meeting was held in the historic city of Braunschweig. Presentations on a very high level and a great accompanying program of the main sponsor PROTEGO have shaped the special character of this meeting.

Experts from the US, China and Europe exchanged their knowledge about the latest developments in process and plant safety.
