JOINT FLEET MAINTENANCE MANUAL

COMFLTFORCOMINST 4790.3 REV A CH-1
z. (Nuclear Powered Ships only) In the absence of a TYCOM and ISIC representative, act for the
TYCOM in approving on-the-spot changes to approved Sea Trial Agendas.
aa. (Nuclear Powered Ships only) When all platform applicable requirements of this instruction are
completed to the OIC's satisfaction and when permission has been received from the ISIC, proceed to
sea in accordance with the operations order and carry out the approved Sea Trial Agenda.
ab. (Submarines only) If possible, participate in two at sea periods prior to initial Sea Trials as follows:
(1) Accompany the preceding ship of the class on the first Sea Trial to learn how the propulsion
trial is run (except first ship of class).
(2) Participate in an underway period of at least five days duration approximately six months prior
to the final phase of Crew Certification. The purpose of this ride is to refamiliarize the PCO
with those functions unique to being underway so as to ensure the safe conduct of his own
initial Sea Trials and shakedown. This underway period also allows him to validate his crew's
training program. This underway period should be on a ship, preferably of the same class,
which is concentrating on basic ship/submarine operations, such as Selected Refresher
Training or Independent Ship Exercise (ISE), so he can witness such evolutions as: coming to
periscope depth, snorkeling, ventilating, casualty training, etc. If the new construction
schedule has 10-12 weeks between Power Range testing and the final phase of Crew
Certification, the PCO should go to sea approximately two months before initial criticality.
The intent is for the PCO to go to sea after having been in the Industrial Activity for a fair
amount of time (normally one year or more), but with sufficient time remaining to improve his
own training program if necessary. During these underway periods, the PCO should spend
time on the bridge and also observe piloting and navigation.
NOTE: IF NOT POSSIBLE TO PARTICIPATE IN TWO AT-SEA PERIODS AS DESCRIBED ABOVE,
THE ISIC AND TYCOM WILL COORDINATE REQUIRED TRAINING.
ac. (Submarines only) Request that the ISIC conduct a salvage inspection in accordance with the policies
set forth in Volume IV, Chapter 18 of this manual.
(1) Coordinate salvage inspection support requirements as may be needed by the inspecting team
to fulfill the requirements of Volume IV, Chapter 18, Appendix A of this manual.
(2) Ensure Volume IV, Chapter 18, Appendix B of this manual is completed and furnished to the
Senior Inspecting Officer prior to the commencement of the Salvage Inspection.
(3) Ensure all ship's data called out in Volume IV, Chapter 18, Appendix A of this manual is
assembled and staged prior to the inspection for ease of reference by the inspecting team.
(4) Take corrective action on all discrepancies found during the Salvage Inspection. Inform the
ISIC of corrective action prior to commencement of Fast Cruise.
ad. (Submarines only) Ensure a copy of the salvage plan has been provided to the escort ship designated for
Sea Trials. Coordinate communications and operational procedures with the escort ship to ensure the
escort is fully informed of the submarine's condition and intentions.
ae. (Submarines only) Concur with the Supervising Authority message that the material condition of the
ship is satisfactory to commence Fast Cruise.
