What is the Purpose?
To establish policy and as ign responsibilities for the Ship'S 3-M System in accordance with references (a) OPNAVINST 4700.7 (Series) and (b) NAVSEAINST 4790.8B .
This instruction provides the current Navy 3-M System policy; reference (b)NAVSEAINST 4790.8B provides implementation guidance .
What is Scope a?
The Ship' s 3-M System applies to all ships, service craft , small boats , and non- aviation fleet test and support equipment, with the exceptions as noted in paragraph 4. c .
What is Scope b?
Common support equipment used by both ship's force and naval aviation units shall have Planned Maintenance System (PMS) support provided under reference (b) . Scheduling of this maintenance by naval aviation units may be done under the Naval Aviation Maintenance Program to avoid duplicat ive and redundant schedules .
What is Scope c?
The Ship'S 3-M System does not apply to nuclear propulsion plants and as sociated test equipment under the cognizance of Commander, Naval Sea Systems Command (COMNAVSEASYSCOM) (SEA 08), f leet ballistic missile systems, or aeronautical support equipment covered in the Nava l Aviation Maintenance Program. Also excluded are civilian operated and maintained ships, small boats, and service craft, unless specifically included as a requirement in a Base Operating Contract (BOC) or other similar document .
What is Scope d?
Maintenance Program. Also excluded are civilian operated and maintained ships, small boats, and service craft, unless specifically included as a requirement in a Base Operating Contract (BOC) or other similar document .
What is Scope e?
Shore activity level of participation in the Ship's 3-M System shall be at the request of the shore activity's senior command and will be provided on a cost reimbursable basis. Equipment used a shore which is identical to shipboard installed equipment with Ship's 3-M support will be maintained using existing 3-M coverage .
The Ship'S 3-M System is the nucleus for managing a float and applicable shore station equipment. How does it do this?
This system provides maintenance and material managers throughout the Navy with a process for planning, acquiring, organizing, directing, controlling and evaluating the manpower and material resources used to support maintenance .
The Ship'S 3-M System is designed to provide for managing maintenance and maintenance support to achieve maximum equipment operation readiness. The Ship's 3-M System shall provide for what?
- (1) Standardization
- (2) Efficiency
- (3) Documentation
- (4) Analysis
- (5) Configuration Status Accounting (CSA)
- (6) Scheduling
achieve uniform maintenance standards and criteria
effective use of available manpower and material resources in maintenance and maintenance support efforts .
recording maintenance and maintenance support actions to establish a material history.
used to improve reliability and maintain ability of systems and equipment, and to reduce cost of material owner ship.
Configuration Status Accounting (CSA)
reporting and recording changes to installed equipment, equipment configuration specifications, and ship board location.
standardized method for planning, managing, executing and tracking maintenance requirements and accomplishments. This includes component requirements from the Class Maintenance Plans (CMP) and the Integrated Class Maintenance Plan (ICMP) .
What is Policy A?
a . The Ship' s 3-M System is a management tool that provides efficient and uniform methods for conducting and recording preventive, alterative, and corrective maintenance. Planned Maintenance System (PMS) and Maintenance Data System (MDS) tools are provided to manage ship maintenance.
What is Policy B?
PMS is a standardized method for planning, scheduling, and accomplishing preventive maintenance by ship's force. PMS maintenance procedures will be developed in accordance with Reliability-Centered Maintenance (RCM) concepts as specified inreferences ( c ) and (d). The procedures are to be developed by the activities of the Systems Commands (SYSCOMs) responsible for the development and procurement of the systems / equipment for active, new construction, major conversion and activation of ships, boats, and crafts. The procedures are to be the minimum required to maintain equipment in a fully operable condition within specifications. PMS supersedes all organizational level planned or preventive maintenance systems or programs. Where a difference between the requirements and/or procedures of PMS and other technical publications or systems exists, PMS requirements will prevail. Differences shall be reported using PMS feedback reporting procedures.
What is Policy C?
To reduce PMS requirements while in extended maintenance periods and other times when equipment is not operated, an Inactive Equipment Maintenance (IEM) system will provide modified PMS procedures for the maintenance of systems and equipment .
What is Policy D?
MDS is the means by which maintenance personnel can report applicable maintenance requirements and configuration changes on all categories of equipment. MDS will be setup so that maintenance personnel will record maintenance data only once.
What is Equipment Configuration Status Accounting?
Configuration status accounting, or the ability to accurately document, track and maintain the configuration of a ship's systems is a critical factor in maintaining proper shipboard logistics support. NAVSEASYSCOM maintains a central database with the ships' configuration data .
What is Configuration Data Manager (CDM)?
For each ship class, a single activity called a Configuration Data Manager (CDM), has been designated the control authority for accuracy and completeness of the configuration information. Prior to ship delivery, the SYSCOM and the delivering activity are responsible for the initial accuracy and completeness of the central database. After delivery, it is imperative that the ship maintains and updates its configuration data in the Ship's Equipment File (SEF), through the submission of configuration change reports.
An item is considered to be a Conf iguration Worthy Item (CWI) if one or more criteria are met. How many criteria are there?
What is criteria (a) of deciding a Configuration Worthy Item (CWI)?
( a ) Any item that is bought from an outside activity
What is criteria (b) of deciding a Configuration Worthy Item (CWI)?
(b) Any item, including software that has a separate specific ation
What is criteria (c) of deciding a Configuration Worthy Item (CWI)?
( c ) Any item that has a separate drawing,
What is criteria (d) of deciding a Configuration Worthy Item (CWI)?
(d) Any item that is a separate line item or subline item on a purchase order or contract
What is criteria (e) of deciding a Configuration Worthy Item (CWI)?
( e ) Any item that has or requires any form of separate technical or logistics document ( e .g., supply support, test equipment requirement, calibration standard requirement, technical manuals and/or repair standards, PMS, e t c .), Maintenance Assist Modules (MAMs), intermediate and/or depot level maintenance plans or drawings, installation or configuration control drawings and/or selected records,
What is criteria ( f ) of deciding a Configuration Worthy Item (CWI)?
( f ) Any item needed to support software tracking
What are alteration installation activities required to provide upon completion of installation?
Alteration installation activities are required to provide configuration change data to the ship upon completion of equipment installation. Configuration changes made by the ship are reported through the Ship's 3-M System. For ships with Maintenance Support Centers (MSCs ), the MSC will research a approve all configuration change requests.
What are the overall responsibilities for the commands of the operating forces?
Commands of the operating forces are responsible for the proper implementation of the Ship's 3-M System in the Fleet, and are responsible for informing appropriate seniors in the chain of command of those conditions that affect material readiness. The development of management tools at the command level is encouraged.

- (3) Review the resources requested for the operation, improvement, and support of the 3-M System by all levels of leadership a float and a shore; and supporting requirements in the budget effort. The program requirements will be submitted by Commander, Fleet Forces Command (USFF) to OPNAVN43 for review.
- (4) Approve management applications of the MDS and PMS.
What are the responsibilites of Commander, Fleet Forces Command (USFF) as it applies to the 3-M?
