APPENDIX U

MINIMUM DOCK TRIALS REQUIREMENTS (SUBMARINES ONLY)

1.Dock Trials. Ship's Force Dock Trials provide the opportunity to test and check out systems, components and portable equipment prior to the Fast Cruise training period simulating underway conditions. Although normally a period of one day is assigned for integrated Ship's Force Dock Trials, tests and evolutions performed in the one to two weeks prior to the Dock Trial date may be accepted by the CO as fulfilling the requirements of this paragraph. The purpose of Dock Trials is to afford the ship an opportunity to demonstrate that major systems and equipments are in fact ready to support Sea Trials. It is expected that individual equipments will have been satisfactorily tested prior to commencement of the integrated operational tests afforded by Ship's Force Dock Trials.

1.1 Supervising Authority. The industrial activity may desire to conduct “machinery checkouts” or system checks prior to the Ship's Force Dock Trials in order to test the propulsion plant or other ship's systems. In order to support these evolutions, close liaison between the ship's CO and the industrial activity will be required. For these evolutions, completion of repairs or modifications to all ship's systems are not required except for those systems which directly support the proposed tests.

1.2 Scheduling of Tests. The scheduling of Ship's Force Dock Trials is flexible. Ship's Force Dock Trials may be scheduled by mutual agreement between the ship and the supervising authority but must take place prior to certification of crew/material readiness with adequate time allowed for collection of deficiencies discovered during the Ship's Force Dock Trials. Preparation of the agenda and schedule for the Dock Trials is the CO's responsibility.

1.3 Extent of Trials. Ship's Force Dock Trials are conducted by the Ship's Force and are normally unhampered by repair work. This applies to the entire ship not just the propulsion plant. The trials may be witnessed by the industrial activity.

APPENDIX W

MINIMUM SEA TRIALS REQUIREMENTS FOR INDUSTRIAL ACTIVITY AVAILABILITIES LESS

THAN SIX MONTHS DURATION (SUBMARINES ONLY)

  1. Sea Trial Agenda. This Appendix delineates the minimum requirements incident to Sea Trials following industrial activity availability/RAV/RAD. Additional events listed in Appendix AN, may be included as desired by the CO.
  2. Sea Trial Rules. The following rules apply to conduct of trials and tests associated with industrial activity availabilities, NAVSEA or David Taylor sponsored Trials/Tests or any other situation where the ship is requested to conduct trials or tests:

a. No test or trial event shall be conducted that requires crew intervention to avoid exceeding normal operating limits. Trial agendas will be based on the expectation that the ship will remain within normal operating limits of the SOE and at angles less than 30 degrees.

b. The trial director must be prepared to project whether the next event might exceed normal operating limits based on the empirical results of the previous event. A run that is predicted to exceed normal operating limits should be deleted along with the more demanding runs of that sequence.

c. Any run which will result in exceeding normal operating limits of the SOE or 30 degree angles but which is essential to provide adequate test data must be specifically approved by the TYCOM. The test/trial sponsor will obtain this permission.

d. A violation of the SOE limit of exceeding a 30 degree angle, not previously approved, should be reported by unit SITREP. The TYCOM will resolve the situation.

e. Specific written approval by the TYCOM is not required to operate outside the upper limits of the SOE, i.e., shallow and fast, while conducting the following operations during Sea Trials or tests in accordance with an agenda approved by the ISIC, NAVSEA or higher authority:

(1) Conducting full power runs or cavitation curves.

(2) NAVSEA sponsored acoustic trials in accordance with a David Taylor Research Center acoustic trial agenda.

f. In cases where troubleshooting is required, it must meet the following criteria or a formally approved change to the agenda is mandatory.

(1) The troubleshooting does not violate any rules listed in paragraphs 1.a through e of this Appendix or any other requirement of the trials agenda.

(2) The troubleshooting will not result in the ship being in a certain condition before that condition is reached during the normal testing sequence. For example, troubleshooting requiring the ship to be deeper than 200 feet cannot be done until after the deep dive. Likewise, troubleshooting requiring large angles or turn rates cannot be done until after the completion of the steering and diving operational tests and the large angle tests.

3.Test Phasing. The Sea Trials should be scheduled and phased to support actions enroute to the test dive area, in the test dive area, prior to the deep dive, etc., subject to the amplifying notes.

4.The following tests and evolutions will be carried out on the surface enroute to the test dive area and prior to the initial tightness dive:

a. Underway. Rig for dive. Energize heaters to stills.

b. Conduct operational test of rudder in normal and emergency modes (See Note 5).

c. Navigation system check. Takes fixes by all electronic, celestial, and visual means and compare.

d. Test underway log(s) using measured mile or navigational fixes to determine accuracy.

e. Test accuracy of all bearing transmitters and indicators. Compare sonar, visual and radar bearings.

f. Check operation of all radars. Demonstrate accuracy by conducting simultaneous radar and visual plot.

g. Inspect stern tube packing gland/seals and circulating water flow.

h. Test fathometer(s) and compare with charted soundings.

i. Run ahead at full power long enough for temperatures to reach a stable value. After readings have stabilized, operate rudder through full throw in each direction in normal and emergency power. Refer to reference (u) regarding depth of water. Check out hand modes.

j. Ahead flank to back emergency. (See Note 12).

k. Run system up to full power. Full power run system to be consistent with backing pressure limitations on plane and rudder rams and within turbine limitations. Operate rudder through full throw.

l. Check operation and accuracy of ship's gyro compass.

m. Rendezvous with escort, if an escort is required. Conduct radio and sonar communications checks (See Note 1).

n. Test all control surfaces in all modes.

o. Flood variable tanks to computed compensation less a safety factor.

p. Operate trim and drain pumps.

q. Test variable ballast system for proper operation.

r. Test low pressure air, normal and EMBT blow systems. (See Note 13).

s. Ensure air banks are charged to within 200 psi of full pressure.

t. Ensure aft MBT blow systems are fully operational and in a normal line up configuration.

u. Ship's Force instruct Sea Trials riders on the proper use of Emergency Air Breathing System.

5.The following tests and evolutions will be carried out immediately prior to or during the initial tightness dive:

a. Obtain navigational fix and take sounding. Maximum depth of water is 400 feet as specified in the applicable TYCOM Operational Order.

b. Transmit initial tightness dive message. Conduct a running dive to periscope depth. Obtain speed. Trim, if practical, at periscope depth. If sea state requires deeper submergence, proceed slowly to 150 feet to obtain speed trim. Use conservative angles and speed on initial dive.

c. Check operation of ship control systems, including depth indication (See Note 2).

d. When escort is required, communicate with escort on WQC at each depth increment or at 10 minute intervals, whichever is sooner. If communications are lost, return to depth at which communications can be established before continuing (See Note 1).

e. All hands inspect for leaks and correct them.

f. Vent the fuel system if sea pressure compensated.

g. At periscope depth, operate all masts checking optics and leakage. Observe speed and depth restrictions for masts without violation of the SOE (See Note 11).

h. Test operation of trim and drain system.

i. Operate all Main and Auxiliary Sea Water hull and back-up valves and those other valves worked during the availability. Equalize all sea pressure on all systems designed for test depth as set forth in reference (ac) (See Notes 9 and 10).

j. Test the SPM (See Note 30 in Appendix AN of this chapter).

k. Conduct operational test of signal ejectors (See Note 4).

6.The following tests and evolutions will be carried out following the initial tightness dive and prior to the deep dive:

a. Transmit initial tightness dive complete message. Charge air banks and battery if necessary. The ship may be submerged while charging air banks provided the depth of the ship does not exceed other guidelines in this instruction, or those of the flooding bill or ship's operating procedure.

b. If escort is required, detach escort after initial tightness dive. Escort will then proceed to station for deep dive. Ensure that deep dive rendezvous time and location are clearly established before escort is released. The escort may be detached after completing all initial tightness dive events and surfacing using EMBT blow from depths of 400 feet or deeper. The escort may be used for additional testing on the transit. Transit depths shall not exceed initial tightness dive depths.

7.The following tests and evolutions will be carried out immediately prior to or during the deep dive:

a. Ensure that air banks are charged to within 200 psi of full pressure.

b. Line up MBT system for normal operation.

c. Take sounding. Accurately fix ship's position within the specified dive area along with the maximum water depth as given in the applicable TYCOM Operational Order. Transmit the commencing deep dive message.

d. Submerge to periscope depth and trim the ship.

e. Obtain stop trim. Take readings required to make a check of ballasting.

f. Trim ship to maintain neutral buoyancy (See Note 3).

g. Line up propulsion plant for maximum reliability in accordance with ship's instructions.

h. Rig ship for deep submergence. All systems should be in the maximum secure condition with unnecessary sea systems isolated as prescribed in reference (ac).

i. Station additional personnel throughout the ship to inspect for leaks as deemed necessary.

j. At 150 feet, 200 feet and then in increments of 200 feet while above and descending to one-half the maximum operating depth and every 100 feet or other lesser specified increments thereafter down to the maximum authorized operating depth:

(1) Inspect for leaks.

(2) Adjust trim (See Note 3).

(3) Communicate with escort (if escort required) at each 100 feet a depth increment or at 10 minute intervals, whichever is sooner. If communications are lost, return to a depth at which communications can be re-established before continuing (See Note 1).

k. At depths listed for hull valve cycling in reference (ac) and at the maximum authorized operation depth:

(1) Check accuracy of gauges and repeaters (See Note 2).

(2) Conduct operational test of signal ejectors (See Note 4).

(3) Check shafting bearings and stern tubes for excessive heating, leakage and noise. Sealol shaft seals must be tested at each depth specified in reference (ac) testing one seal for 20 minutes, and shifting to the other seal and testing the other seal for 20 minutes before leaving each specified depth.

(4) Cycle rudder and planes through full throw to check for binding. Cycling of rudder and planes through full throws should be limited to test depth minus 100 feet (See Note 5).

(5) Operate all Main and Auxiliary Sea Water hull and back-up valves and those other seawater system valves worked during the availability (using remote closures, as applicable, from flooding control stations) that are required to maintain propulsion and other functions vital to the ship's operation at increments of depth specified in reference (ac).

NOTE: REQUIRED SYSTEMS ARE LISTED IN PARAGRAPH 4B OF REFERENCE (AC). OBSERVE RESTRICTIONS ON OPERATION OF SYSTEMS LISTED IN PARAGRAPH 4D OF REFERENCE (AC).

NOTE: TRASH DISPOSAL UNITS (TDU) WITH BALL VALVES WILL NOT BE OPERATED BELOW 200 FEET. TDUs WITH FLAPPER VALVES WILL NOT BE OPERATED BELOW 150 FEET.

(6) Operate trim and drain pumps, discharging to sea.

(7) Cycle main vents to check for binding.

l. Surface fully with EMBT blow in accordance with applicable URO MRC. Check air bank pressures before and after blow.

m. Transmit completion of deep dive message.

8.The following tests and evolutions will be carried out submerged following the deep dive:

a. Steering and diving operation at full speed (See Note 6).

b. Full power run (See Notes 6, 7, and 8).

c. Steep angles - operate ship through several depth changes using large up and down angles to check operation of ship machinery (See Note 7).

d. Time raising each periscope and mast at maximum depth and speed for which they are designed. Check training feature where applicable.

e. Run and observe air conditioning plants throughout trials noting deficiencies. Operate the Lithium Bromide air conditioning plant (if installed) to demonstrate ability to carry entire maximum existing ship's air conditioning load or 100 percent capacity.

NOTES

1. In the execution of any Sea Trial, whether escorted or not, submarine COs are reminded of their responsibility to communicate with escorts and/or shore authorities within the prescribed previously agreed upon time limits to avoid initiation of lost submarine procedures.

2. Compare all depth and pressure gauges; check operation of planes and rudder in all modes, etc. Depth and pressure gauges should be checked as soon as each next specified depth is reached.

3. Deep dive should be conducted using moderate speed and constantly adjusting trim at depths indicated in paragraph 7.j of this Appendix to maintain neutral buoyancy. Moderate speed shall be defined as that range of speed that allows the ship optimum recovery (as shown on recovery curves) if loss of stern plane control and/or flooding occurs.

4. Integrity of torpedo tubes and signal ejectors shall be established by admitting sea pressure through equalizing lines or flooding connection and the muzzle doors operated before conducting operational tests. Shoot water slugs from torpedo tubes as required by the Anti Submarine Warfare (ASW) Test Program down to ship/torpedo tube limiting depth, whichever is less. Shoot pyrotechnics from signal ejector on initial tightness dive and at test depth on deep dive only if any work was accomplished on the signal ejectors or if an escort vessel is required for the trial.

5. At maximum safe speed, operate the rudder and planes through full throw in both directions in normal and emergency power.

6. Run full power submerged for at least two hours. Operate at minimum non-cavitating depth but not to exceed 400 feet (SSN 688 Class submarines may exceed 400 feet, as required, consistent with the SOE but not to exceed one-half test depth plus 50 feet); water depth is not limited for this event.

7. Note that the required sequence of events is initial dive, deep dive, full power run submerged, back emergency, then high speed maneuverability and steep angle tests. Initial high speed ship control tests, steep angle tests and exercises at major casualties shall be conducted in water that does not exceed one and one-half times design test depth (which equates to collapse depth).

8. The full power submerged ahead test for commissioned nuclear powered submarines shall be terminated by a back emergency bell. The duration of the back emergency shall be limited to 45 seconds, to be followed immediately by an appropriate ahead bell. Caution must be exercised to avoid developing sternway.

9. Those seawater systems which are not required for normal safe operation of the ship at test depth but which have been designed for and may be subjected to test depth pressure should not be subjected to submergence pressure during the initial dive to any specified depth; e.g., blowing sanitary tanks. See reference (ac).

10. This evolution (initial operation of hull and back-up valves in fully submerged condition) at depths other than specified in reference (ac) is intended for crew training is not technically required. Evolution may be abbreviated or deleted on case basis as desired by ship's CO.

11. Any evolutions (e.g., mast testing, propeller cavitation data collection, etc.) required by the Sea Trials Agenda which violate the ship's SOE must be approved by the TYCOM prior to Sea Trials in accordance with paragraph 2 of this appendix.

12. The full power run with an ahead flank bell is to be terminated with a back emergency bell, consistent with current Main Propulsion Operating Limits (shaft torque is not a limiting factor in this test). The duration of the back emergency bell will be limited to 45 seconds, to be followed immediately by an appropriate ahead bell. The 45 second limit will:

a. Standardize the crashback requirements throughout the submarine force.

b. Provide a backing transient similar to that experienced during a stern plane jam.

c. Be short enough that ship will not gather sternway.

13. Test the normal and emergency blow systems in their normal valve line ups. A static blow shall not be used.

14. This evolution may be conducted anytime after the deep dive, provided an escort ship was not required for Sea Trials.

APPENDIX AN

MINIMUM SEA TRIALS REQUIREMENTS FOR INDUSTRIAL ACTIVITY

AVAILABILITIES GREATER THAN SIX MONTHS DURATION (SUBMARINES ONLY)

1. Sea Trial Policy. The following applies to the conduct of trials and tests associated with ships following major industrial activity availabilities, NAVSEA or David Taylor sponsored Trials/Tests or any other situation where the ship is requested to conduct trials or tests:

a. No test or trial event shall be conducted that requires crew intervention to avoid exceeding normal operating limits. Trial agendas will be based on the expectation that the ship will remain within the normal operating limits of the SOE and at angles less than 30 degrees.

b. The trial director must be prepared to project whether the next event might exceed normal operating limits based on the empirical results of the previous event. A run that is predicted to exceed normal operating limits should be deleted along with the more demanding runs of that sequence.

c. Any run which will result in exceeding normal operating limits of the SOE or 30 degree angles but which is essential to provide adequate test data must be specifically approved by the TYCOM. The test/trial sponsor will obtain this permission.

d. A violation of the SOE limit or exceeding a 30 degree angle, not previously approved, should be reported by unit SITREP. The TYCOM will resolve the situation.

e. Specific written approval by the TYCOM is not required to operate outside the upper limits of the SOE, i.e., shallow and fast, while conducting the following operations during Sea Trials or tests in accordance with an agenda approved by the ISIC, NAVSEA or higher authority:

(1) Conducting full power runs or cavitation curves.

(2) NAVSEA sponsored acoustic trials in accordance with a David Taylor Research Center acoustic trial agenda.

f. In cases where troubleshooting is required, it must meet the following criteria or a formally approved change to the agenda is mandatory.

(1) The troubleshooting does not violate any rules listed in paragraphs 1.a through e of this Appendix or any other requirement of the trials agenda.

(2) The troubleshooting will not result in the ship being in a certain condition before that condition is reached during the normal testing sequence. For example, troubleshooting requiring the ship to be deeper than 200 feet cannot be done until after the deep dive. Likewise, troubleshooting requiring large angles or turn rates cannot be done until after the completion of the steering and diving operational tests and the large angle tests.

2. Test Phasing. The Sea Trials should be scheduled and phased to support actions enroute to the test dive area, in the test dive area, prior to the deep dive, etc., subject to amplifying notes as follows:

a. The following tests and evolutions, as summarized in Appendix AO, will be carried out on the surface enroute to the area and prior to the initial tightness dive:

(1) Underway. Rig for dive. Compensate. Light off heaters to stills.

(2) Conduct operational tests of rudder in normal and emergency modes.

(3) Navigation system check. Take fixes by all electronic, and visual means and compare.

(18) Test the SPM (See Note 30).

(19) Vent the fuel system after diving if system is sea pressure compensated.

c. The following tests and evolutions, as summarized in Appendix AO, will be carried out following the initial tightness dive and prior to the deep dive:

(1) Six hours of ISE for crew training (See Note 19).

(2) Charge air banks and battery as necessary. The ship may be submerged while charging air banks provided the depth of the ship does not exceed other guidelines in this instruction or those of the flooding bill or ship's operating procedures.

(3) Detach escort after initial tightness dive. Escort will then proceed to station for deep dive. Ensure that deep dive rendezvous time and location are clearly established before escort is released. The escort may be detached after completing all initial tightness dive events except the surfacing using EMBT blow to accommodate additional testing or the transit as described in Appendix AO.

(4) Operate IFF and ESM equipment. If possible, use aircraft (See Note 2).

(4) Measure resistance across and to ground from each side of all sonar hydrophones, projectors, and transducers (See Note 29).

NOTES

1. Demonstrate accuracy by conducting simultaneous radar and visual plot.

2. Event is optional with regard to sequence. May be conducted at any time during Sea Trials and is not a prerequisite to deep dive. If listed with initial tightness dive events, completion is not mandatory prior to proceeding with remainder of trials.

3. Test on all possible antenna combinations including emergency antennas and emergency radio equipment.

4. Log RPM, ship's speed, temperatures, pressures, etc. Refer to reference (u) regarding depth of water.

5. If ASW test program does not specify ship's speed, conduct with ship at maximum ahead speed.

6. The full power run with an ahead flank bell is to be terminated with a back emergency bell, consistent with current Main Propulsion Operating Limits (shaft torque is not a limiting factor in this test). The duration of the back emergency bell will be limited to 45 seconds, to be followed immediately by an appropriate ahead bell. The 45 second limit will:

a. Standardize the crashback requirements throughout the submarine force.

b. Provide a backing transient similar to that experienced during a stern plane jam.

c. Be short enough that no ship will gather sternway.

7. Full power run astern to be consistent with backing pressure limitations on plane rudder rams and within turbine limitations.

8. As required by Underway Consolidated Operability Test, check target designation system, alignment of sensors to bench marks and transmissions to receivers. Determine lost motion. Run test problems on position keeper and angle solver, etc. Conduct transmission checks to tubes.

9. In the execution of any Sea Trial, whether escorted or not, submarine COs are reminded of their responsibility to communicate with escorts and/or shore authorities within prescribed, previously agreed upon, time limits to avoid initiation of inadvertent lost contact or submarine disaster procedures.

10. Pumps should be tested in industrial activity, prior to Sea Trials, to determine that they can pump against a test depth head.

11. Additional requirements may be imposed at the discretion of the CO.

12. Use conservative angles and speed on initial dive.

13. Compare all depth and pressure gauges; check operation of planes and rudder in all modes, etc. Depth and pressure gauges should be checked as soon as the next specified depth is reached.

14. Integrity of torpedo tubes, launchers and signal ejectors shall be established by admitting sea pressure through equalizing lines or flooding connection and the muzzle doors operated before conducting operational tests. Shoot water slugs from torpedo tubes as required by ASW test program down to ship/torpedo tube limiting depth, whichever is less. Shoot pyrotechnics from signal ejectors or launchers on initial tightness dive and at test depth on deep dive.

15. Those seawater systems which are not required for normal safe operation of the ship at test depth but which have been designed for and may be subjected to test depth pressure should not be subjected to submergence pressure during the initial dive to any specified depth, e.g., blown sanitary tanks (See reference (ac)).

16. Check operation of electrodes, head valve and each snorkel safety circuit. Demonstrate operation of air compressors and stills, if possible, while snorkeling.

17. Depth increments for cycling vital sea valves are as set forth in reference (ac).

18. This evolution (initial operation of hull and back-up valves in fully submerged condition) at depths other than specified in reference (ac) is intended for crew training and is not technically required. Evolution may be abbreviated or deleted on case basis with concurrence of the embarked TYCOM representative.

19. Each person involved in Sea Trials should be allowed to obtain a minimum of six hours of continuous, uninterrupted sleep during any 24 hour period.

20. Stop trim to be conducted at the most desirable time during the trials.

21. Deep dive should be conducted using moderate speed and constantly adjusting trim at depths indicated in paragraph 2.d.(10) in this Appendix to maintain neutral buoyancy. Moderate speed shall be defined as that range of speed that allows the ship optimum recovery (as shown on recovery curves) if loss of stern plane control and/or flooding occurs.

22. Reference (ac) prescribes procedures for system operation during deep dive.

23. Cycling of rudder and planes through full throws should be limited to test depth minus 100 feet.

24. Test to demonstrate the ability of the tank to withstand external pressure.

25. At maximum safe speed, operate the rudder and planes through full throw in both directions in normal and emergency power. Time evolutions and check against design values.

26. Note that the required sequence of events is initial dive, deep dive, full power run submerged, back emergency, then high speed maneuverability and steep angle tests.

27. Run full power submerged for at least two hours. CO may schedule full power run for four hours if he deems it necessary. Submarine depth during the submerged full power run should be consistent with the SOE, based on the EMBT blow from maximum authorized operating depth being previously accomplished. Those ships which are limited in depth should conduct full power trials at a depth not to exceed maximum operating depth minus 100 feet.

28. Completion of full power, back emergency and deep dive runs are prerequisites for high speed maneuverability and steep angle tests. Initial high speed ship control tests, steep angle tests and exercises during major casualties shall be conducted in water that does not exceed one and one-half times design test depth.

29. The spherical array need not be done if an array purge or power into the array measurements are scheduled at a later date.

Reference (s).

* - May be delayed to permit additional testing, commencing pre-transit valve cycling or transit submerged. However, first surface after initial tightness dive must be by EMBT blow from 200 feet and must be conducted prior to deep dive.

** - An escort is required on the initial tightness dive and on subsequent first dives to any deeper depths, i.e., the first dive to any depth requires an escort. EMBT blow escort requirements given in paragraph 3.6.8.4.9 of this chapter.

*** - No post initial tightness dive evolution will be conducted at a depth deeper than a previous depth at which valve cycling in accordance with reference (ac) has been accomplished.

# - One half test depth plus fifty feet for SSN 688 Class submarines.
