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.
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.
Class III - Leakage of fluid great enough to form drops that fall from the item being
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
The following fuel and hazardous material leakage procedures apply for any fuel, chemical, or bilge
Class 1, 11 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.
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.
Maintenance log. Always record the time and date of PMCS, any deficiencies noted, and corrective action taken
in the PMCS log book.
Major components. The lighting system consists of normal and emergency interior lighting and exterior
searchlights and floodlights. Major components, their basic functions and location on the barge are listed in Chapter 1.
