1.General.
a. Items pertaining to SRC/DSRV seating surfaces and buoy cable angle tests require substantial support equipment and are designated for industrial activity accomplishment.
b. Configuration differences are noted as comments in the reference column.
2.Reach rods, universal joints, and connecting links in the superstructure should be secured with non-corrosive pins. Inspect valve stems for misalignment and ensure that reach rod connection is one of square socket design with the non-corrosive pin used only to secure the reach rod to the universal.
3.All high/low salvage valves are to be tested for freedom of operation at the frequency specified, except during the salvage inspection conducted incident to an overhaul on ships with soft seated external salvage valves. Written certification by the Commanding Officer that specified soft seated external salvage valves have been overhauled by the industrial activity or Ship's Force and have been successfully hydrostatically tested will constitute certification that the valve operates freely, providing the inspection of operating gear (Part I, item 2B of this Appendix) for each valve so certified is satisfactory. If the results of the inspection of operating gear are not satisfactory, or doubt exists concerning freedom of operation, the specific valves in question shall be checked. Provide appropriate container for collecting anti-freeze drained from salvage piping when hull valve is cycled. Ensure controlled re-assembly in accordance with QA requirements is performed when installing salvage caps. Exercise caution to prevent liquid in salvage air piping from impinging on nearby equipment when hull valve is cycled. Ensure anti-freeze is added to piping after inspection to prevent freezing.
4.Caps and salvage air hose connections that have pipe threads are not designed to include gaskets. Use of gaskets is not considered necessary. Coating of threads is desirable, particularly to prevent seizure. Apply a light coat of Termaline grease or Neolube on threads.
5.Discrepancies between physical installation and salvage plans are to be reported to the TYCOM with an information copy to all plan holders.
6.Low salvage line strainers located in the reactor compartment of nuclear powered submarines are not, in most cases, visible through the lower level viewing windows. Therefore, certification by the Commanding Officer that the reactor compartment low salvage line strainer has been verified properly installed by Ship's Force during the course of the salvage inspection will suffice. Certification to this effect shall be included in the salvage inspection letter of Appendix C of this chapter.
7.The inspected ship's vice the inspecting command's salvage wrench shall be used if the inspecting command is another submarine. Discrepancies in the actual, versus plan, number of turns shall be reported to the TYCOM with information copy to all plan holders. Report discrepancies to the nearest 1/8th of a turn.
8.Prior to testing Outboard Diesel Exhaust Valve, ensure replacement shear pin is available onboard.
9.When inspecting the gagging gear for the inboard ventilation exhaust valve and the inboard ventilation induction valve, the valve linkages shall be inspected and the valves shall be adjusted in accordance with the requirements in the Non-Primary Plant Valves Technical Manual or individual ship's valve drawing.
10. On some designs, operation of the gagging device overrides the regular operating gear of the valve indicator in such a manner that the entire mechanism must be reset/readjusted before the normal operating gear or the valve position indicator will function as intended. If the gagging mechanism is operated or used for any reason, the mechanism shall be reset and the valve subsequently opened and closed by the normal operating gear in every manner in which the gear is designed to function to ensure the valve is in proper operating condition.
11. Inspections of the SRC/DSRV seating surface for flatness and surface area free of protuberances are to be conducted during overhaul or SRA. Procedures are set further in NAVSHIPS Drawing DSRV-800-2656512. (On SSBN 726 Class submarines, MRP 1230-081-003 refers.) Inspections are to be performed early in the industrial phase to identify and correct discrepancies prior to commencement of fast cruise.
12. Diver's knife and timer may be stored in secure stowage in escape compartment.
13. Shelf life is computed from date of manufacture which is printed in code on the battery. For example, a battery code "1187" means the battery was manufactured in the 11th month of 1987. For expiration dates, see Naval Supply Systems Command Publication 4105, List of Items Requiring Special Handling.
14. The allowance of escape appliances for submarines with two escape compartments consists of 110 percent of complement in each compartment, and for submarines with three escape compartments consists of 55 percent of complement in the forward and aft compartments and 110 percent of complement in the midships escape compartment. Additionally, the following quantity of non-inflatable life preserves are to be carried for topside use:
a. SSN allowance - 20.
b. SSBN allowance - 38.
15. Escape appliances are to be equipped as follows:
a. One cell flashlight or chemical personnel marker light attached, whistle, and dye marker stowed in pocket. Batteries will be in case/box lots stowed with escape appliances. Ensure shelf life of batteries or personnel marker light will not be exceeded prior to next PMS check.
b. Toggle and cord attached to belt.
16. Life rafts are to be equipped as specified on the inventory lists within the raft.
17. Man overboard bags to be equipped as specified in Man Overboard Casualty Procedures.
18. Man overboard swimmer to be qualified as a swimmer first class with appropriate entries in service record.
19. The number of desalter kits required in each compartment is based on the difference between the amount of potable water normally available and the minimum potable water requirements for that compartment. S9002-AH-DCB-010/(C)SSN/SSBN, Standard Submarine Damage Control Book for SSNs and SSBNs (U), states that one gallon of potable water will support the survival needs of a man for about two weeks. Two weeks is considered sufficient time for a modern day rescue operation. Therefore, minimum potable water requirements for escape compartments are one gallon of potable water for each member of the crew and minimum potable water requirements for non-escape compartments are one gallon of potable water for each person normally stationed in that compartment. Normally available potable water includes potable water tanks,Normally available potable water includes potable water tanks, reserve feed tanks, hot water heaters, chill water expansion
tanks, demineralized water tanks, battery water tanks, canned water and juices. Each desalter kit makes one gallon of potable water and has an indefinite service life if manufactured after 1960 (FMSOINST 4440.27D provides guidance for disposition of kits manufactured prior to 1961 and for damaged kits). SSBN 726 Class submarines carry no desalter kits.
20. For SSBN 726 Class only, one or more of the Logistics and Escape Trunks (LET) will be removed during refit. When removed, the LET is isolated from service air and electric power. Communications circuits, electrical power, and charging manifold tests should be conducted prior to LET removal to ensure piping and electrical system continuity, and tested again upon reinstallation.
21. Exercise extreme caution if testing operation of 4500 psi compartment pressurization valves.
