The 8th International Workshop on Cryogenics Operations (Cryo-Ops 2018)

General cryogenic maintenance policy and recent updates for CERN equipment

Not scheduled

15m

Main building (IHEP)

Speaker

Mr Frederic FERRAND (CERN)

Description

- Maintenance policy for cryogenic equipment at CERN integrated in the Computerized Maintenance Management Software - Review of recent changes of maintenance approach for specific piece of equipment - Input of failure maintenance and breakdown analysis for maintenance and consolidations - Implementation of the updated strategies for Long Shut Down 2 of LHC in 2019-2020

Summary

CERN operates several large cryogenic systems including those serving the LHC machine complex and its associated detectors, together with the Cryogenic Test Facilities and Cryogenic Distribution services of smaller size. For this large spectrum of cryogenic systems, maintenance and consolidation policies are being standardized to reduce downtime and thus improve availability.
In this talk, emphasis will be given to failures observed in the past years of operation and actions taken, either to prevent or to mitigate new risks of occurrence. We will share recent review of the general maintenance plan demonstrating its adaptation towards an improved overall reliability and considering its implementation for execution during the Long Shut Down 2 of LHC scheduled in 2019-2020.
