1. ConstraintsSolution ConsequencesOpportunities RE-TENDERING OF ST-CV MAINTENANCE CONTRACT Michele Battistin - CERN - ST/CV Group Workload Budget Lump-sum contract -assure the availability and the reliability of the whole installation park. Years 2005 long shutdown -LEP dismantling -LHC projects development Normal shutdown rotation -Shutdown period -Running period LHC Project budget problems -Budget contraction -Expenditure postponement During the next three years, the ST/CV group will be deeply involved in the installation works for the LHC project. During this period the need for maintenance activity will decrease. The minimum level will be reached during the “long shutdown” of the PS and SPS machines in 2005. The budget for the maintenance will decrease accordingly, thus the CV group had to review its maintenance strategy. The new contract, which started on January 1 st 2003, has been defined to cope with these workload variations during the next years and to guarantee the minimum maintenance activity on the existing equipment. A lump-sum contract based on a win-win strategy has been discarded. The contractor no longer has to guarantee the performance of the CERN cooling and ventilation systems. A new price list strategy based on performance indicators and penalties has been chosen. The contractor now has to guarantee the performance of every maintenance operation demanded by CERN. This modification obliged the Operation section of the CV group to undergo a reorganization during 2002 and is going to force deep changes in its work organization. Pricelist contract -every maintenance activity is defined with its unitary price. Variation on LHC equipment number -LEP dismantling -LHC projects development Pompes centrifuge Pompes puisard Classes (33) Categories (147) Frequency weekmonthquarteryear........ Responsibility -CERN has to define maintenance levels for each equipment. -CERN has to order and check every individual activity. -Contractor has to assure the result of every individual activity he will be asked for. -Contractor has to consult CERN in the definition of the maintenance level. MP5 database -Add equipment hierarchy to functional one -Classify all 16.000 equipment present on the database nowadays in the defined class/category grid. -MP5 assumes a central and fundamental role in the CERN-contractor relation. It became the strategic core of the business. Instruction Lists (391) Work organization -Equipment organization of the database facilitate transversal communication between teams. -Verbal orders can’t be accepted. They have to be entered in MP5 database. -All CERN technicians, even those unfamiliar with using PCs, have to adopt MP5 as a working tool. Win-win partnershipPenalties & Perf. Indic. Integration -Different approaches of maintenance have been integrated in a unique statement to define “instruction list” for any category and class of equipment. -In the past procedures could have separate “lives” and diverge. -Now local improvements will have a global effect on the maintenance procedures. Predictive maintenance -The coexistence of functional and object database structures can permit the historical analysis of the systems in both directions. -This analysis will allow us to foresee the future behavior of installations and to guide maintenance policy. Reliability tools -MP5 history can be treated with dedicated tools to estimate the reliability of different equipment. -Criticism of equipment can be determined from observation of the history of their failures, their frequency, gravity and their detection facility. CERN needed a very flexible tool to modulate the maintenance workload
