Senior Engineering Team (SET) SET Members: • Electrical Engineer (Control Systems, Infrastructure, RF) • Mechanical Engineer (Cryogenics, Vacuum) • Physicist (Accelerator, Diagnostics, Beam lines) • Industrial Engineer (Maintenance Management, Documentation) • Safety Specialist (“online” safety, procedures for present and future) • Two accompanying part time technicians Responsibilities: • Operation • Systems Commissioning and Acceptance • Maintenance • Engineering and Technical Office • Training
Operation • Most infrastructure systems were accepted and serve accelerator installation and commissioning purposes • SET members ware trained up to supervisor level to operate the infrastructure systems
Accelerator Systems Commissioning and Acceptance (1) • SET members are participating and assisting in accelerator installation, commissioning and acceptance tests • Effort is lead by the accelerator contractor personnel and is under their responsibility
Accelerator Systems Commissioning and Acceptance (2) • Emphasis is on thorough learning and understanding of all systems and components • SET members spend about 40% of their time on these tasks
Engineering and Technical Office • Engineering tasks and Technical Office responsibilities are entwined • Engineering • R&D of accelerator supplementary systems (Control, Diagnostics, infrastructure) • Writing maintenance and operating procedures • Technical Office • Documentation of engineering tasks • Updating of documentation and drawings • Archiving of engineering data • Maintenance schedule • Coordination among SARAF and external contractors and suppliers • Purchasing of spare parts and stock management
Maintenance • Maintenance procedures concern operational and mechanical systems conditions • Currently, maintenance is mainly performed on • The building • Infrastructure systems • Cryogenics • Part of the accelerator vacuum and RF • The maintenance works are divided into: • Breakdown Maintenance (BM) • Preventive Maintenance (PM) • Predictive Maintenance (PdM)
Breakdown Maintenance (BM) • Most of the systems are still in their warranty periods, so they are usually repaired by the system contractor • In urgent cases, breakdown maintenance is performed by SET members • The procedure for BM is • BM is requested in the commissioning logbook (if encountered during shifts) or in a PM form (if encountered during PM) • The BM Request is accepted and checked by the relevant SET member • A BM form is issued • BM is performed according to the procedures • A BM technical report is prepared • The BM technical report is checked and approved by the SET head • The data base of the Computerized Maintenance Management System (CMMS) is updated • The approved report is logged and stored in the BM archive
Preventive Maintenance (PM) • For accepted systems PM procedures have been written and scheduled by the technical office • The procedures are based on the system contractor requests and maintenance timetables (with small deviations) • PM is performed either by SET members, the system contractor or other external contractors • The procedure for PM is • A PM procedure form is issued by the technical office • PM is performed and reported on the form • The PM report is checked and approved by the SET head • The data base of the CMMS is updated • The approved report is logged and stored in the PM archive
Predictive Maintenance (PdM) • Predictive Maintenance (PdM) is an integral part of preventive maintenance • Measurements of systems parameters are performed routinely to observe patterns and predict equipment breakdowns or malfunctions • Typical measurements and operations include • Thermal imaging of electrical cabinets • Electric current measurements of motors and other equipment • Pressure and flow measurements of process cooling water systems • Gas and water analysis in relevant systems
Computerized Maintenance Management System (CMMS) • For the abovementioned tasks we developed a Computerized Maintenance Management System (CMMS), which enables SET members to schedule and structure maintenance tasks • The SARAF CMMS is a Microsoft Access based maintenance database management system which includes • Assets Management • Preventive Maintenance Scheduling and Management • Report Generation
CMMS – Asset Management Component Data Screen
CMMS – Asset Management Service Providers Screen
CMMS - PM Scheduling and Management Weekly Monthly Quarterly Semi-annual
CMMS – Reports Generation The 2007 Annual BM report
Conclusions • Development and assimilation of maintenance and engineering systems during accelerator installation and commissioning presents a big challenge for SARAF Senior Engineering Team. • Currently, the biggest effort is the accelerator installation and commissioning, so maintenance and engineering receive a smaller share of the workload • It is unequivocal that after the accelerator systems will be accepted, the maintenance load will grow accordingly. Therefore major SET tasks are: • Verified written procedures • A CMMS including all of the accepted systems • Appropriate training of SET members • Development of a maintenance culture
