(6) Increased Inspections. Perform weekly as well as Before Operations PMCS if-
(a) You are the assigned operator and have not operated the item since the last weekly PMCS
(b) You are operating the item for the first time.
(7)
Leakage definitions. In checking for fluid leaks, the following leakage definitions apply to all ROWPU
barges and barge equipment, product water, and seawater leakage by class type.
(a) Class I - Seepage of fluid (as indicated by wetness or discoloration) not great enough to form
drops.
(b) Class II - Leakage of fluid great enough to form drops, but not enough to cause drops to drip
from the item being checked/inspected.
(c) Class III - Leakage of fluid great enough to form drops that fall from the item being
checked/inspected
CAUTION
Equipment operation is allowable with minor leakages (Class I or II). However, the fluid
level or operating pressure of the Item being checked/inspected must be considered. When
in doubt, notify the shift leader or bargemaster.
When operating with Class I or Class II leaks, continue to check fluid levels as required by
PMCS and operating instructions.
(8)
The following fuel and hazardous material leakage procedures apply for any fuel, chemical, or bilge
system.
WARNING
Class I, II or III leaks or seepage occurring in a fuel, chemical, or bilge container, tank, line,
piping, or valve can cause fire or health hazards.
(a) If any leaks or seepage from a fuel, chemical, or bilge container, tank, or fluid line is
detected, it must be immediately reported to the shift leader or bargemaster for
corrective action.
(b) To prevent combustible or toxic fumes from collecting or contaminated material from
spilling, exercise extreme caution after detecting leaks or seepage of flammable or
hazardous material.
c.
Continuous operation. When equipment must be kept in continuous operation for extended periods of time,
check and service only those items that can be checked and serviced without disturbing operations.
Perform complete checks and services when the equipment can be shut down.
d.
Maintenance log. Always record the time and date of PMCS, any deficiencies noted, and corrective action
taken in the PMCS log book

Systems description
C-3.1 Deckhouse ventilation system description. The deckhouse is provided with fresh air articulation by
manually operated hatches and electrically driven fans. Fresh air is supplied by opening 17 louvered hatches, 10
port and 7 starboard. (Doors may also be opened.) Air circulation is increased by using six exhaust fans on the
deckhouse top . These are controlled by circuit breakers on power panel 2 and motor controllers on port and
starboard bulkheads in the Reverse Osmosis Water Purification Unit (ROWPU) space. Fan motors and louvered
hatches can be used in different combinations to control air movement. The deckhouse ventilation system also
includes electrical wiring, controls, and an electrical emergency shutoff.
