E072/ST-HM - A dynamic maintenance strategie to meet the requirements of the LHC installation

The new ST-HM contract E072 for the maintenance of transport and handling equipment is designed to obtain the high operating reliability as required for the LHC installation and to respect the situation of limited resources at CERN at the same time. The contract is based on a dynamic maintenance strategy. It contains a flexible maintenance contingent that is essential to prepare the equipment for extremely important and critical utilization phases that will come up during the LHC installation. Due to very little utilisation and non-strategic importance of approximately 80% of the whole inventory the preventive maintenance service will be reduced to a minimum. In order to convert this strategy into practice it is necessary to establish well-defined interfaces between the users that realise the project schedules and the maintenance service.
