the system drawing
c) Re-qualifying system hoses, volume tanks, high
Re-certifying DOT 3AA flasks/bottles
f) System configuration changes in support of mission
testing documented on controlled work procedures
Should the scope of work exceed minor work (as described above),
termination or suspension of system certification may be
required. This applies whether the work is accomplished during
scheduled maintenance, as day-to-day work, or to correct a
casualty. The applicant should immediately notify the SCA when
this work is required so the SCA can make a determination with
respect to termination or suspension. Examples of significant
work that may terminate or suspend system certification are:
Welding or brazing on the pressure boundary
Overhauling the unmanned pressure test facility.
Pre-Overhaul Requirements. Prior to the commencement
of overhaul or repair of an unmanned pressure test facility, the
applicant should submit the following to the SCA for review:
a) A detailed definition of the scope of the overhaul,
including a list of repairs, alterations, modifications and
significant components to be replaced, etc.,
b) The overhaul or repair work package should include,
provisions, tests and inspections to be accomplished. All
procedures or processes to be followed must also be included.
A schedule showing major overhaul milestones.
Pre-Overhaul information should be submitted as early as possible
to allow sufficient time for review by the SCA. The SCA, as
early as possible, in conjunction with appropriate technical
authorities, should review all work and procedures/processes that
involve system certification.
In cases where the work package includes alterations, the Naval
Facilities Engineering Command Hyperbaric Facilities Maintenance
Manual, NAVFAC MO-406, may be used to provide guidance for the
control of the alteration process. The timing of formal
technical design reviews should be negotiated between the
applicant and the SCA and should be dependent upon the complexity
and uniqueness of the alteration.
