3M
&
Navy Supply System
Objectives
• Objective of the 3-M system
• Purposes of the 3-M subsystems
– Planned maintenance subsystem (PMS)
– Maintenance data collection system (MDCS)
• Duties of the division officer and work
center supervisor in the conduct of the 3-M
system
3-M System
• What is the 3- M System?
• Maintenance, Material, Management
• Purpose:
– Provides a means of managing maintenance
aboard a ship
– Provides efficient uniform methods of
conducting and recording preventive and
corrective maintenance in a way that allows
easy access to the collected data
3-M Objectives
• Standardization - achieve uniform maintenance
standards and criteria
• Efficiency - effective use of available manpower
and material resources in maintenance
• Documentation - recording of maintenance to
establish material history
• Analysis - provision to be used in the
improvement of maintainability and reliability of
systems and equipment, and the reduction of cost
of material ownership
3-M Objectives
• Configuration Status Accounting - a means of
reporting and recording changes in what
equipment is installed onboard, equipment
configuration specifications, and shipboard
location
• Scheduling - standardized method for scheduling,
planning, managing, and tracking maintenance
required and accomplished
3-M Subsystems
• Planned Maintenance System (PMS)
– Standardized method of planning, scheduling,
and accomplishing preventive maintenance
• Maintenance Data System (MDS)
– Allows maintenance personnel to report
applicable maintenance requirements and
configuration changes to equipment
PMS Terms
• Preventive maintenance
– actions intended to prevent or discover
functional failure (ie changing oil / filters,
cleaning components)
• Corrective maintenance
– actions taken to fix equipment that has failed or
is working below standards
PMS Terms
• LOEP - List of Effective Pages
– List of MIP’s for each piece of equipment within a
specific work center (division)
• MIP - Maintenance Index Page
– Issued for each piece of equipment
– Index of all MRC’s for equipment
• MRC - Maintenance Requirement Card
– Detailed procedure for performing maintenance (how,
who, what, when)
Periodicity Codes
•
•
•
•
•
•
•
•
D - daily
2D - every 2nd day
W - weekly
M - monthly
2M - Every 2nd month
Q - quarterly
S - semiannually

• R - situational
• U - unscheduled
maintenance
• LU - lay-up
• PM - periodic maint.
• SU - start up
• OT - operational test
Cycle PMS Schedule
• Planned maintenance between major
overhauls
• Supervised by the department head
• Prepared by using LOEP and MIP’s
• Used to prepare the quarterly schedule

Benefits of PMS
•
•
•
•
•
Increased equipment reliability
Improved planning and management
Simplified records
Excellent training aid
Continuity and standardization of
maintenance
• Increased safety
Problems of PMS
• Not self-starting nor self-sustaining
• Will not automatically and effortlessly
produce good results
• Personnel shortage and turnover
• Training in maintenance required
• Occasional errors must be expected (though
not necessarily accepted)
Maintenance Data
Collection System
• Purpose
– Allows maintenance personnel to report
applicable maintenance requirements and
configuration changes to equipment
• Interaction with supply system
– Equipment request forms
Maintenance Action
Forms
• 2K - ships hand generated form
• 2Q - ships computer generated form
• 2R - Maintenance Facility computer
generated form
Tracking Corrective
Maintenance
• CSMP - Current Ship’s Management Project
– Consolidated listing of corrective maintenance
to be completed
• SFWL - Ship’s Force Work List
– Listing of work center corrective maintenance
to be completed
Supply Interface
• 1240 - hand written supply request
– old method
– generally internal use
• 1348 - computer generated supply request
– internal or external use
Feedback Forms
• Report discrepancies and problems
• Request PMS coverage
• Request PMS materials
Discussion/Emphasis
• Overall importance of preventive
maintenance
• Necessity of corrective action for
maintenance deficiencies
• Impact of 3-M on combat readiness
• Responsibility for 3-M
– Division
– Work center supervisor
