DEPARTMENT OF THE NAVY

NAVAL SEA SYSTEMS COMMAND

SECTION 042

GENERAL ADMINISTRATIVE REQUIREMENTS

042a. Scope This section contains nontechnical requirements and procedures, the intent of the General Specifications for Overhaul of

Surface Ships (hereinafter referred to as GSO), definitions of administrative terms, specification requirements, schedule and correspondence requirements, and similar requirements.

042b. Intent The GSO establishes NAVSEA requirements for the administration and conduct of quality surface ship overhauls. It is the intent of these specifications to obtain a ship or ships with machinery, equipment, and systems complete and in every way ready to perform during its next operating cycle, to the extent that work is specifically authorized, and to secure uniformity in workmanship and procedure, and standardization of all auxiliaries and fittings on all ships of the same type. It is the responsibility of work authorizing activities to ensure the technical specifications are invoked for all authorized work assigned to the overhauling activity.

Ship Alterations - The GSO is the primary source of technical requirements for ship alterations. Therefore, the GSO contains the technical requirements to be invoked throughout the SHIPALT and associated drawing development process.

Since SHIPALTS often provide state of the art technical improvements, the GSO cannot totally define all potential design specifications. Therefore, specifications which exceed the requirements specified herein shall be included in the SHIPALT.

The SHIPALT development process shall also include a review of original shipbuilding specifications to assure that SHIPALT specified criteria do not result in inadvertent re-design of an as-built ship design unless an upgrading of ship design is the intent of the SHIPALT. It is not the intent of the GSO to invoke or authorize upgrading of ships systems to current GSO specifications. Should system upgrade be intended, the upgrade will be accomplished by shipalt as outlined in Section 085.

Section 085 herein provides the requirements for the SHIPALT developmental process.

Review of original shipbuilding specifications is required also when developing SHIPALTS for ships built to commercial specifications.

Overhaul and repair - The GSO is the primary source of technical requirements for overhaul and repair of ships' equipment. Other GSO sections herein contain technical specifications for overhaul and repairs including the use of Technical Repair Standards (TRS). Paragraph 042c. further defines overhaul and repair criteria.

It is not the intent of the GSO to invoke or authorize upgrading of ship systems to current GSO specifications. Should system upgrade be intended the upgrade will be accomplished by shipalt as outlined in section 085.

In certain instances, work and test requirements have been identified as a mandatory requirement which the work authorizing activity shall invoke for overhauls. These work and test requirements determined to be mandatory are specifically identified in the applicable GSO section.

It is the responsibility of the overhauling activities to accomplish all work authorized and to comply with the corresponding applicable specifications. Non-compliance with specifications or non-accomplishment of authorized work is subject to waiver and deviation approval in accordance with Section 070 and MIL-STD-973.

The applicable authorizing activity is to notify NAVSEA in writing whenever the authorizing agent does not intend to invoke a specification contained in the GSO, with the authorizing activities supporting rationale. NAVSEA approval is required on such requests.

General - In general, requirements for new and modified systems and requirements for overhaul of existing systems are identified within each GSO section.

Where technical guidance is not considered adequate for new installations or modified systems the cognizant Engineering Agent shall request appropriate guidance from NAVSEA.

These specifications and the individual work specifications define the services and materials to be provided.

The provisions of the GSO do not apply to any work in the reactor plant or tender nuclear support facility area. For overhaul work, routine repair work and alterations in non-reactor propulsion plant spaces on nuclear ships, see Nuclear Supplement, NAVSEA S9AA0-AB-GOS-020.

Unauthorized modifications to naval ships shall not be accomplished. OPNAVINST 4720.93 provides prohibitions against unauthorized modifications and OPNAVINST 4720.2 provides planning procedures for the Fleet Modernization Program (FMP).

Section 042 2

FOR OFFICIAL USE ONLY

With respect to materials of construction and items or components of machinery, equipment, and outfit, which by their nature may be manufactured or procured as distinct items or components, these specifications generally contain requirements and information that pertain to selection, installation, shipboard performance, shipboard inspection and tests, and pre-installation handling by the Contractor. Requirements such as physical or chemical properties, manufacturer test and inspection requirements, or other requirements applicable only to manufacturers, are contained in Government Specifications, standards, drawings, or in other documents referenced herein.

It is, therefore, inappropriate to incorporate any section(s) of these specifications by reference in Contractor procurement documents. Such incorporation imposes an unnecessary burden on manufacturers and suppliers. If one or more paragraphs of these specifications are considered applicable for a particular procurement, they should be expressly quoted in the Contractor's purchase specifications or other procurement documents.

042c. Definitions As based throughout the GSO, the following terms have meanings as indicated:

The Government is the United States Government.

The Department is the Department of the Navy.

The Secretary is the Secretary of the Navy or his authorized representative.

NAVSEA is the Headquarters of the Naval Sea Systems Command, and supersedes NAVSHIPS and NAVORD. Where the term NAVSEA is used in these specifications in connection with letters, instructions, and manuals it shall be understood to include existing non-cancelled documents still having NAVSHIPS/NAVORD/BUWEPS/BUSHIPS designation.

SPAWAR is the headquarters of the Space and Naval Warfare Systems Command.

Wherever such terms as "as approved" "for approval" or "as directed" are used without further qualification, it is the approval, decision, or direction of the Supervisor that is intended.

The term Supervisor, as used in these specifications means the Supervisor of Shipbuilding, Conversion, and Repair, USN. Under certain conditions the duties of the Supervisor may be transferred to a Contract Administration Services Activity of the Department of Defense in which case that activity becomes the Supervisor. The Shipyard Commander assumes the responsibilities and duties of the Supervisor for ships being overhauled in a Naval Shipyard.

A Contractor is a firm holding a prime contract with the Government for overhaul of the ship. For ships being overhauled in a Naval Shipyard, the term "Contractor" shall be construed as referring to the Shipyard Commander.

Specification requirement - A statement of means or criteria (such as size, quality, or performance) governing process, materials, constructions, repairs.

Supervisor Work Specifications are the specific work requirements authorized for the ship overhaul. This term is synonymous with the term Bid Package.

Work items are items of authorized work identified in the Supervisors Work Specifications.

Standards are documents that establish engineering and technical limitations, application of items, materials, processes, methods, and engineering practices.

Overhauled system - A system which is refurbished but not changed, except for replacement of defective equipment.

Modified system - A system where configuration is changed either through a change in the configuration of the equipment or components comprising the system or by relocation of these equipments and components within the system.

New system - A system not previously installed.

Naval Ships' Technical Manual - NAVSEA S9086-AA-STM-000 (hereafter referred to as NSTM) - The NSTM provides technical information and requirements for ships of the United States Navy. The various chapters of the NSTM contain detailed administrative and technical instructions which amplify U.S. Navy regulations and other authoritative documents. The NSTM also provides information to govern industrial activities in ship and equipment repair and overhaul.

Technical Repair Standards (NAVSEAINST 4160.2) (hereafter referred to as TRS) - A TRS is a technical document which provides the minimum requirements and procedures for the overhaul of an item to a specified condition (as defined herein). The TRS is a standard, not simply a procedure or a substitute for a technical or maintenance manual.

Unless otherwise specified, wherever the terms "installed," "fitted," "furnished," or "provided" are used, it is the intent of these specifications that the Contractor shall provide and install or provide adequate onboard stowage for the equipment, as applicable.

Where the term overhaul appears, it shall be construed to include conversion when the ship using this specification is in fact undergoing conversion. The term overhaul as used is intended to include work performed during Regular Overhauls (ROH), Complex Overhauls (COH), Baseline Overhauls (BOH), Selected Restricted Availabilities (SRA), and Phased Maintenance Availabilities (PMA).

Where the term "existing ship" is referenced herein, it is intended to mean the ship under Contract.

Where the term "herein" is used, it is intended to mean these General Specifications for Overhaul of Surface Ships

(GSO).

When reference is made herein to class of overhaul for ship systems and components, the following definitions apply:

3 Section 042

FOR OFFICIAL USE ONLY

Class A - Work that requires such overhaul or repairs, modifications, field changes, ORDALTS or SHIPALTS as will sustain or improve the operating and performance characteristics of the system, subsystem, or component being repaired or altered to meet the "most recent" design and technical specifications for that item. It is intended that the end product be in "like new" condition in appearance as well as in operation and performance. All manufacturers' and technical manual performance standards and specifications, unless superseded by proper authority, will be met, as will all technical documentation. The repair activity will demonstrate that the end product successfully meets all performance criteria specified by the governing specifications. Defining an overhaul as Class "A" means that all actions required to meet the definitions are authorized. The definition is applicable to all components, subsystems, and systems whether machinery, electrical, hull, electronics, or weapons.

Class B - Work that requires such overhaul or repairs as will restore the operating and performance characteristics of a system, subsystem, or component to its original design and technical specifications. If it is required to restore the operating and performance characteristics of an item to other than its original design and technical performance specifications, it must be so specified and the performance criteria defined. SHIPALTS, ORDALTS, MACHALTS, field changes, and modifications, even if applicable, are not to be accomplished unless specified by the customer. Maintenance, adjustment, and calibration routines specified by the applicable instruction manual, unless superseded by authority, are required. The repair activity will demonstrate that the end product successfully meets all performance criteria specified by the governing specifications.

Class C - Repair work on a system, subsystem, or component specified by the work request or that work required to correct the particular deficiencies or malfunctions specified by the customer. The repair activity must demonstrate that the work requested has been accomplished or that the conditions or malfunctions described have been corrected, but the repairing activity has no responsibility for the repair or proper operation of the associated components of the equipment or for the operation of the system as a whole. The term Class "C" is synonymous with the term "repair".

Class D - Work associated with the "Open, Inspect, and Report" type of work request in which the customer cannot be specific about what is or may be wrong with the item. This class of work is intended to be diagnostic and thus may require various tests, followed by inspection, to assist in a complete diagnosis. The repair activity will report findings, recommendations, and cost estimates to the customer for authorization prior to any repair work. When requested by the customer, minor repairs and adjustments may be accomplished without prior authorization to the extent specified.

Class E - Work required to incorporate all alterations and modifications specified for a designated system, subsystem, or component. The repair activity will demonstrate the successful checkout of the work accomplished to assure compliance with the performance standards established for the modification only to the extent of the work performed. When required by the customer, the repair activity will conduct system tests to prove system operability through affected interfaces. Repairs, if any, are minor.

Repair - The word repair is synonymous with a Class "C" overhaul as defined herein.

Concerning Class "B" overhauls - The repair and refurbishment of systems, equipments and components is intended to restore items to their original performance profiles and to assure the items will function properly without failure between ships overhauls. The class "B" repair does not necessarily require all items to be restored to an "as new" condition. Therefore, sections of this GSO include repair specifications and allowances for wear and use (i.e., Sections 300, 503, 505). These allowances for wear and use are provided herein for use when there is no applicable Technical Repair Standard (TRS). Should a class "B" overhaul be required on an item and a TRS has been developed, the Supervisor's Work Specification shall invoke the TRS.

042d. Referenced Documents Documents which are referred to in these specifications or in documents referred to herein are of the types defined below and are hereinafter termed "referenced documents". Referenced documents form a part of these specifications to the extent specified.

Standard drawing - A NAVSEA drawing identified as "Standard Drawing" which delineates arrangements or details of systems, equipment, or components. No departure from a standard drawing is permissible without specific approval.

Type drawing - A NAVSEA drawing identified as "Type Drawing" which delineates or illustrates design features of systems or components. No departure from any feature stated to be mandatory is permissible without specific approval. The illustrative features are subject to detail design development to assure full compliance with these specifications.

Installation Control Drawing (ICD) - A drawing that sets forth information and interface characteristics for an item in terms of area, weight, space, access clearance, drainage, mounting, ship service requirements, cleaning, testing, clearance, and pipe, waveguide, and cable attachments required for the installation and co-functioning of the installed item with related items.

Design Data Sheet (DDS) - A NAVSEA document which contains material for information and guidance in the design or modification of a ship's system or component. Design Data Sheets illustrate typical design and calculation methods and procedures which are acceptable to the Government.

Section 042 4

FOR OFFICIAL USE ONLY

Government specification - A Government document identified as a Federal Specification (Fed. Spec.) or Military Specification (Mil. Spec.) which describes the technical requirements for items, materials, or services, including the procedures by which it will be determined that the requirements have been met.

Government standard - A Government document identified as a Federal Standard (Fed. Std.) or Military Standard, (Mil.

Std.) or by 13 digit NAVSEA publication number, that establishes engineering and technical limitations and applications for items, materials, processes, methods, design, or engineering practices.

Industry standard - A document promulgated by recognized non-Government organizations (such as ANSI, or ASTM) that establishes engineering and technical limitations and applications for items, materials, processes, methods, design, and engineering practices.

Procurement of unclassified Military and commercial specifications and standards referenced in the Supervisors Work Specification is the responsibility of the Contractor. Unclassified Military Specifications and Standards may be obtained from the Navy Printing and Publication Office. Classified Military Specifications are available at the office of the Supervisor.

References - Primary: Any document which is directly cited for use or application by an identifying number or name in these specifications for each particular use or application for which it is so cited.

Sub-tier: Any document which is cited in a primary reference or in a document referenced therein.

Note that any individual document may be a primary reference in one instance, and a sub-tier reference in another.

However, in this instance, it shall be considered primary only for those particular uses or applications for which it is so cited.

042e. Other Requirements Order of precedence - In case of inconsistency between these specifications and referenced documents, the following order of precedence applies:

1. Supervisor Work Specifications

2. GSO Specifications

3. Primary References (i.e., government specifications, NAVSEA standard and type drawings, authorized approved repair standards, NAVSEA Standard Items and NAVSEA Standard Work Items.

4. Sub-tier References

5. (Where this specification is silent), Selected Record Data, Original Working Drawings and Original Ship's Detail

Specifications.

In any case, silence of one document with respect to details shown in another shall not be considered an inconsistency.

Notices, instructions, letters, publications, and standard and type drawings referenced herein form a part of these specifications and shall be those in effect on the date specified in the Supervisors Work Specifications or in the overhaul Contract. If for any reason the Contractor desires to use other than the effective issue or alternates of Industry, Federal or Military Specifications and Standards, or NAVSEA standard and type drawings, he shall obtain Supervisor's approval.

The Contractor is responsible for carefully and critically reviewing drawings, (including SHIPALT drawings), if provided, and the Supervisors Work Specifications immediately upon receipt. In case of error, omission, discrepancy, or lack of clarity in the drawings or specifications, the Contractor shall promptly notify the Supervisor requesting clarification. Work performed, based on such an error, omission, discrepancy, or lack of clarity, shall be at the Contractor's own risk.

Effective issue - The term "effective issue" refers to the issue of a referenced document, as revised or amended, which in accordance with the requirements of this section, forms a part of these specifications. Reference is made normally only to basic Government specification, standard, or drawing number, without prefix zeros or suffix letters or numbers which identify revisions or amendments. However, the effective issue, revision, or amendment shall not be one whose terms of promulgation make it applicable only to agencies other than NAVSEA. Department of Defense or government supplements forming a part of the industry standards apply when the basic standard is invoked. The effective date of issue shall be as defined in the Supervisors Work Specification.

Wherever a primary reference is identified by both its basic number and by issue, revision, or amendment date or designation including those for which specific exceptions are specified, such identified issue shall be the effective issue for the particular use or application cited. Unless otherwise specified, the effective issue of other referenced documents shall be that in effect on the date indicated in the applicable Supervisors Work Specifications.

Use of other than effective issues - The effective issues of referenced documents are those invoked by the Contract and as described herein. In accordance with the procedures specified herein for use of other than effective issues, the Contractor may use document issues other than the effective issues. In the event of the use of other than the effective issue, it is the responsibility of the Contractor to assure that the item or material which is in accordance with a document other than the effective issue is not technically inferior to, and is interchangeable as defined in Section 070 with that prescribed by these specifications, does not adversely affect logistic support, and does not impair performance, life, safety, maintainability, and reliability. If use of other than the effective issue would result in any degradation of the requirements of these specifications, 5 Section 042

FOR OFFICIAL USE ONLY

the Contractor shall recommend action which will assure that the substitute item or material is technically acceptable for the application.

Where primary references are referred to by citing a particular issue (including those for which specific exceptions are specified), approval shall be obtained to use any issue other than the particular issue cited.

It is intended that repair and replacement of existing equipment and structure shall duplicate the existing installation.

When it is not practicable to duplicate the existing installation, applicable specifications and standards of a later date for equivalent work may be used after approval of the change.

Where other primary references are referred to only by use of the basic identification name or number (without citing a specific issue date or designation), the Contractor may use a later issue (including a superseding issue of a different number) or, subject to written approval, may use an earlier issue (including a superseded issue of a different number) than the effective issue. The Contractor shall notify the Supervisor promptly upon electing to use such later issue and shall identify the expected impact of such substitution upon essential system design parameters or components. If the Supervisor does not concur with the substitution, he will notify the Contractor in writing within 20 calendar days of receipt of the Contractor's notice of election to use a later issue. It is understood that electing to use earlier or later issues than those specified shall be at no cost to the Government. Where an earlier or later issue is used, it shall be used in its entirety (that is, all requirements pertaining to a particular type or class), unless specifically approved otherwise.

Unless otherwise specified, these specifications do not prescribe effective issue requirements of sub-tier references.

Allowance List - The Contractor shall provide such data as may be required by the Supervisor to aid the latter in the preparation of the allowance lists.

Departures - Departures from specifications shall be reported by the Contractor in accordance with MIL-STD-973.

042f. Overhaul Schedules and Reports The Contractor shall prepare schedules necessary for the purpose of establishing an orderly and systematic overhaul program.

1. These schedules shall include but shall not be limited to the following:

a. A Principal Events Schedule for overhaul of the ship. This schedule should be prepared by the Contractor, with schedule and actual dates listed for each item. These networks shall reflect to the maximum extent practicable the manner in which the total project will be performed. Networks shall contain a NAVSEA provided set of milestone events together with sufficient detail to provide intermediate check points at which progress toward each of these milestones can be measured. The number of NAVSEA provided milestone events will be held to the minimum number required for effective management control, but in no case shall the required number cause undue complication in computer updating of the basic networks. Should this condition arise, additional networks to accommodate all milestone events, shall be developed and maintained, to facilitate computer updating. Networks shall be updated on a continuing basis to reflect changing situations.

Two copies of an updated complete set of networks shall be submitted to the Supervisor not later than 120 days prior to the start of the overhaul availability. Unless otherwise specified these networks shall be in PERT/CPM format.

b. The Overhaul Contractor shall process the total network data and produce a report consisting of the NAVSEA provided milestone events together with the scheduled date, expected date, latest allowable date and slack time (positive or negative) for each milestone event. Slack time shall be shown in terms of working days. The milestone event report will be provided in three sequences: by NAVSEA milestone event number and title; by scheduled event date; and by slack time. The milestone event reports shall be accompanied by a narrative analysis of the four most critical paths and a statement of management action being taken or planned and other comments as appropriate. The initial milestone report shall be submitted with the preliminary network.

c. As a minimum, the Overhaul Contractor shall perform computer updating of basic network data to reflect current status, as follows: (1) Under the initial (overhaul preparation) Contract, monthly. This will include, but is not limited to, re-estimates of time, additions, deletions, completions, and changes to schedule dates. A revised milestone event report shall be provided from each updating. Updated milestone event reports, together with supporting narrative statements, shall be submitted so as to arrive at NAVSEA not later than seven calendar days after the cut-off date for the report data. The Contractor shall attend meetings for discussions concerning scheduling and networks when requested by NAVSEA.

2. A drawing schedule showing the required availability dates, current schedule dates, and final delivery dates of all drawings, including vendor drawings. The schedule shall be maintained current and shall contain other data as approved by the Supervisor. The schedule shall be submitted to NAVSEA as directed by the Supervisor.

3. A schedule of required dates for Government Furnished Material (GFM), showing the dates on which this material is required at the shipyard for fabrication, erection, or installation. This schedule shall contain other data as approved by the Supervisor. Schedules shall include dates for technical support requirements.

4. A material ordering schedule, as required by the Supervisor, showing the dates on which each item should be ordered, updated to show current estimated and actual contract award dates, to meet the shipyard required dates as listed in the schedule of required dates for material. This schedule shall contain other data as approved by the Supervisor.

Section 042 6

FOR OFFICIAL USE ONLY

5. A technical publications schedule listing all Contractor-furnished technical manuals and books, including changes, or modifications, as well as microfilm including a breakdown of types and categories thereof. This schedule shall indicate the estimated and actual shipping date of preliminary and final publications to ships, follow yards (including appropriate Naval Supervising Activity) and tenders. Where provision of a publication is dependent upon receipt of design or lead yard furnished publication, the estimated and actual receipt date of the design or lead yard publications shall be shown. The schedule shall also contain a brief explanation for delinquency including designation of activity responsible for current holdup and expected release date. The above schedule shall be submitted monthly after the start of overhaul and shall contain other data as approved by the Supervisor.

6. Test schedules shall be kept current with the progress of the work. As each item on each schedule is completed, this shall be indicated, thus, these schedules will also serve as reports on the progress of the work. Similarly, if the Contractor encounters difficulty in meeting requirements or anticipates difficulty in complying with the contract schedule dates, this shall be indicated. Overhaul schedules and reports required throughout these specifications shall be prepared.

7. When it is determined by the Contractor that additional work or material procurement may be necessary in order to produce a reliable or complete repair for a work item, a report containing supporting data shall be submitted as early as possible. Such reports shall contain the name and hull number of the ship, job order and work item numbers, a description of the conditions found with supporting data, recommendations, and a list of material required.

8. NAVSEA may assist the Contractor in the preparation of required schedules. However, such assistance will not relieve the Contractor of his responsibility for effective scheduling and timely completion of the ship.

9. Post Overhaul Analysis Report - A post overhaul analysis shall be prepared after the end of each overhaul. This analysis should identify significant problems (non-nuclear) encountered during pre-overhaul and overhaul periods.

The Contractor shall submit a report coincidentally with the departure report. Narrative analysis of critical items with management action and the networks established in 042f form the basis for this report.

Specific areas of consideration are as follows, however, they are not intended to be all inclusive or to preclude other areas of consideration.

a. Estimated vs actual costs, limit to gross differences. Estimated costs are those provided by a Naval Shipyard in the Overhaul Work Booklet, and for private overhaul yards as provided in the Contract Proposal. Actual costs are those provided in departure reports.

b. Performance for overhaul preparation and conduct.

c. Performance analysis, including event identification, of early and late overhaul completion.

d. Delineate areas of major shipwork where original plans for accomplishment were changed due to either infeasibility or because a better way was found.

e. Timeliness and accuracy of software and Long Lead Time Material (LLTM) product availability; or inadequacy and resultant impact on overhaul.

f. Impact of emergent or new work items on overhaul cost and schedule.

g. Effectiveness of liaison arrangements, including Liaison Action Record (LAR).

h. Recommendations for improvement of future overhaul work packages.

i. Recommendations on minimizing material problems.

j. Comparison of milestone/key events schedule versus actual accomplishment dates.

k. Effectiveness of the Pre-Overhaul Test Program including recommendations where the Contractor is responsible for such pre-overhaul testing.

l. Innovative scheduling or work procedures used which contributed to reduction in time or cost.

m. Recommendations and/or corrective actions taken to preclude delays or cost overruns or both.

n. Lessons learned and recommendations to improve planning and support (such as drawing or material delivery).

o. Final material costs as compared to the initial material estimates, and impact statement due to inflationary trends.

p. Impact upon final overhaul costs as compared to initial planning estimate due to changes in shipyard wage rate.

q. Impact upon overhaul cost, mandays, and schedule due to major changes in technical and administrative requirements. The intent of this analysis and report is to provide to management in NAVSEA, SUPSHIPS, PERA, Overhaul Yards, Planning Yards, and Work Sponsors, solutions to critical problems arising in the actual pre-overhaul planning and overhaul conduct, thereby avoiding costly and time-consuming efforts for solving problems in subsequent overhauls when solutions may already be available.

042g. Specification Change Procedures Advance Change Proposals (ACPs) may be initiated by users of the GSO. GSO ACPs are to be submitted to Norfolk

Naval Shipyard (Code 240) and must provide the following information:
