 CHAPTER 3
MAINTENANCE OF HYPERBARIC FACILITIES
3.1 DEFINITION OF TYPES OF MAINTENANCE
Maintenance Types. Maintenance, in the most general
3.1.1
terms, involves all actions required to keep the hyperbaric
facility in a condition which will allow the safe operation of the
For NAVFAC man-rated
facility for all mission requirements.
hyperbaric facilities, maintenance consists of the following
maintenance types:
o
General Maintenance
o
Repairs
o
Alterations
o
Overhauls
Each of these maintenance types is defined in the paragraphs that
follow.
3.1.2
General Maintenance. General maintenance includes
all maintenance that is routine in nature and which does not
involve the fabrication of materials.
Included under general
maintenance are actions such as calibration, replacement of soft
goods, lubricant renewal, painting, filter replacement, system and
component inspections, cleaning, sampling of oil and air, and
testing.
General maintenance consists of two sub-elements which are
addressed in detail under Section 3 of this chapter:
o
Scheduled Maintenance
o
Unscheduled Maintenance
3.1.3
Repairs.
Repairs are maintenance actions which
require the fabrication of piping or components, and for which
there is no deviation from the original design.
Included under
repairs are actions such as:
replacement of piping, component
replacement involving welding, machining of parts or components,
cladding, stud replacement and weld repairs. It is emphasized that
repairs do not involve deviation from the original design.
Therefore, the replacement of a valve with the valve of a different
manufacturer which meets the original design specifications,
constitutes a repair.
Should the replacement valve not meet the
original design specifications, or should such specifications not
exist as is the case with some older facilities, then the valve
change would be treated as an alteration.
