4 3-M System What is the 3- M System? Maintenance, Material, Management Purpose:Provides a means of managing maintenance aboard a shipProvides efficient uniform methods of conducting and recording preventive and corrective maintenance in a way that allows easy access to the collected data- Maintenance and Material Management System- : To provide for managing maintenance and maintenance support in a manner which will ensure maximum equipment operational readiness
5 3-M ObjectivesStandardization - achieve uniform maintenance standards and criteriaEfficiency - effective use of available manpower and material resources in maintenanceDocumentation - recording of maintenance to establish material historyAnalysis - provision to be used in the improvement of maintainability and reliability of systems and equipment, and the reduction of cost of material ownership
6 3-M ObjectivesConfiguration Status Accounting - a means of reporting and recording changes in what equipment is installed onboard, equipment configuration specifications, and shipboard locationScheduling - standardized method for scheduling, planning, managing, and tracking maintenance required and accomplished
7 3-M Subsystems Planned Maintenance System (PMS) Standardized method of planning, scheduling, and accomplishing preventive maintenanceMaintenance Data System (MDS)Allows maintenance personnel to report applicable maintenance requirements and configuration changes to equipment
8 PMS Terms Preventive maintenance Corrective maintenance actions intended to prevent or discover functional failure (ie changing oil / filters, cleaning components)Corrective maintenanceactions taken to fix equipment that has failed or is working below standardsa. Definitionb. Purpose. Component parts: Discuss the principal planning and scheduling documents as well as working guidelines for conducting actual maintenance.d Associated terms(1) Corrective maintenance(2) Planned/Preventive maintenance(3) Work center(4) Work center supervisor

11 Cycle PMS Schedule Planned maintenance between major overhauls Supervised by the department headPrepared by using LOEP and MIP’sUsed to prepare the quarterly schedule
12 Quarterly Schedule Visual display of Work Center PMS Covers 13 weeks Department Head supervisesUsed to prepare weekly PMS schedule
13 Weekly Schedule Visual display of Work Center PMS Covers 7 days Permits scheduling PMS dailyDivision Officer supervisesWCS assigns tasks and updates as maintenance is performed
14 Benefits of PMS Increased equipment reliability Improved planning and managementSimplified recordsExcellent training aidContinuity and standardization of maintenanceIncreased safety
15 Problems of PMS Not self-starting nor self-sustaining Will not automatically and effortlessly produce good resultsPersonnel shortage and turnoverTraining in maintenance requiredOccasional errors must be expected (though not necessarily accepted)
