detected during regular inspections
▪ Monitoring:▪ Digital monitoring is deployed to help decision making in
order to enhance service life
▪ Routine and specialized maintenance:▪ Several maintenance contracts are used on Normandy (stay

▪ Heavy maintenance▪ Major maintenance operations were conducted in the
past
▪ CCI draws up and updates annually an heavy maintenance plan until the end of the concession, ie2027.
▪ 7 years before the end of concession, an audit will be realized by the State to identify the heavy maintenance operations to be scheduled until 2027
▪ CCI wants to prepare this dialogue by using innovative methods and tools in compliance with standards (ISO 55 001, ISO 31 000 and NF EN 13269)

▪ Align decision and practises over lifecycle regarding performance, risk, cost
▪ Communicate and report to the State
▪ Promote collaborative work between the team
▪ Some examples of (fictitious) results:
