31. SPARE PARTS  In 2008, significant increase of information related to spare parts:  CERN has increased the information available in D7i and in other databases for pumps and Hazemeyer cubicles  Contractors trace the requests in e-log and statistics and reports can be easily retrieved  Items with long procurement delays and low cost have been identified and placed in stock  Purchasing of materials for preventive maintenance has been better anticipated Spare parts 2008

32. SPARE PARTS Spare parts 2008

33. SPARE PARTS  In 2009, continue with the same policy keeping in mind the main constraints: budget, storage area and manpower. Spare parts 2009

34. CONCLUSIONS   Consolidation projects are essential to:   maintain existing CV installations   increase reliability of services to CERN users   A small proportion of CV resources is still dedicated to new projects and can’t be neglected   Operation and maintenance sections in charge of daily tasks (including shutdown preventive maintenance) are a key factor to ensure trouble free service   Spare parts is also a key issue: information and storage area are at present two areas to improve
