e. The following general conditions apply:
(1) A shipbuilder generated, Supervising Authority/Ship Program Manager/ TYCOM approved
agenda is required for each Sea Trial.
(2) All trial periods must be organized such that each member of the crew has an opportunity to
get six uninterrupted hours of sleep during each 24 hour period. Sea Trial elements which can
be accomplished by a normal watch section may be conducted concurrently with crew rest
periods.
(3) Sea Trials should normally be scheduled to allow at least three weeks between CT/AT and the
scheduled delivery date.
(4) The prerequisites for Nuclear Powered Aircraft Carrier and submarine Sea Trials are a Pre-
Critical Reactor Safeguard Examination (RSE), Crew Certification, Dock Trials and Fast
Cruise.
(5) Each submarine watch section shall be provided with approximately two hours experience
submerged at moderate speeds prior to the deep dive or full power run.
(6) Critical operation of reactors while naval nuclear powered ships are in a Naval or private
industrial activity will be governed by reference (j). Prior to delivery, permission to conduct
critical reactor plant operations must be obtained by the Supervising Authority from NAVSEA
Nuclear Propulsion Directorate (08).
(7) During inspections, deficiencies should be limited to those items for which a correction is
mandatory to ensure safe operation during Sea Trials.
(8) At the start of Fast Cruise the ship should be ready in all respects for the commencement of
Sea Trials with the exception of the additional training the crew will receive during Fast
Cruise.
(9) Inspectors must determine that all work/testing necessary to support Sea Trials has been
completed or identified for completion prior to commencement of Fast Cruise including the
following:
(a) All ship systems which affect safe operation during Sea Trials must be operable.
(b) All work necessary for safe operation of the ship during Sea Trials has been
satisfactorily completed and tested. Included must be a check for any special
configuration or installations ensuring that they have been authorized by the proper
authority (NAVSEA and TYCOM), that their impact has been fully assessed and that
the Sea Trial agenda addresses these impacts or limitations.
(10) NAVSEA and the Supervising Authority are expected to properly discharge their
responsibilities for quality assurance and control of authorized industrial work (e.g., it is not
necessary for the Immediate Superior in Command (ISIC) inspections to inspect the quality of
the pressure hull radiographs or other nondestructive test records of the industrial activity).
