Chapter 2—ADMINISTRATION, SUPERVISION, AND TRAININGall the information you have available is amanufacturer’s part number, then you must alsofill out and submit, along with the NAVSUPForm 1250, a DD-1348-6 Form, NON-NSN REQ-UISITION. For information on how to fill outthese supply forms, review Military Requirementsfor PO 3 & 2, volume II of OPNAVINST 4790.4,or ask your ship’s supply personnel for assistance.Whenever you find it necessary to requestmaterials or repair parts, remember two things:1. If at all possible, find the correct NSN foreach item requested. All materials now in thesupply system have been assigned an NSN, andyou should be able to locate them by using theCOSAL and the other sources of informationavailable to you such as the following:a. NAMEPLATES on equipment supplyinformation regarding the characteristics of theequipment. Nameplate data seldom, if ever,include the exact materials required for repairs;however, the information given on thecharacteristics of the equipment and on pressureand temperature limitations may provide usefulclues for the selection of materials.b. MANUFACTURERS’ TECHNICALMANUALS are furnished with all machinery andequipment aboard ship. Materials and repair partsare sometimes described in the text of thesetechnical manuals; more commonly, however,details of materials and parts are given on thedrawings. Manufacturers’ catalogs of repair partsare also furnished with some shipboard equip-ment; when available, these catalogs are a valuablesource of information on repair parts andmaterials.c. SHIPS’ PLANS, BLUEPRINTS, andOTHER DRAWINGS available on board ship areexcellent sources of information on materials andparts to be used in making various kinds ofrepairs. Many of these plans and blueprints arefurnished in the regular large sizes; but lately,microfilm is being used increasingly for thesedrawings. Information obtained from plans,blueprints, and other drawings should always bechecked against the information given on theship’s COSAL to be sure that any changes madesince the original installation have been noted onthe drawings.2. Work informally with the supply depart-ment personnel who are actually responsible foridentifying and requesting material. You have thetechnical knowledge, and you know what youneed. If you cannot find the correct stock number,however, your job is to give enough standard iden-tification information, such as manufacturer partnumbers, and Allowance Parts List/ComponentIdentification Description (APL/CID) numbers,so that supply personnel on board ship or ashorecan identify the item you want. Experiencedsupply personnel are familiar with identificationpublications and can help you to locate the cor-rect stock numbers and other important identi-fying information.SHIP EQUIPMENT CONFIGURATIONACCOUNTING SYSTEM (SECAS).—When thestructure or composition of either the ship or aparticular system or equipment on board a shipis modified, this modification must bedocumented. This action will ensure proper ac-counting of configuration changes, and will helpimprove supply and maintenance supporttechnical manuals, PMS coverage, updatedCOSAL, etc., to your ship. SECAS is thedesignated system responsible for maintaining theconfiguration status reported by your ship.Although the responsibility for identifying andreporting these changes rests at all levels of thecommand, the work center supervisor is respon-sible for ensuring that the proper documentationis completed and processed as described in volumeII of OPNAVINST 4790.4.OPNAV Form 4790/CK, Ship’s Configura-tion Change Form, is used to report configura-tion changes at the individual equipment level.SHIP-TO-SHOP WORK.—Many repair jobsare designated by the ship or approved by therepair activity as “ship-to-shop” jobs. In this typeof job, the ship’s force does a large part of therepair work. For example, the repair or renewalof a damaged pump shaft might well be writtenup as a ship-to-shop job. The ship’s force willdisassemble the pump and remove the shaft. Thenthe shaft and any necessary blueprints or technicalmanuals are delivered to the designated shop ofthe repair activity. After the shaft has beenrepaired, or a new one has been made, it is2-21
