Section I. General system information
6-1 Introduction. Chapter 6 contains Preventive Maintenance Checks and Services for the Reverse Osmosis Water
Purification Unit Barge Shore Discharge System. Operating and maintenance procedures are described in detail in TM
55-1930-209-14&P-6. TM 55-1930-209-14&P-6, Appendix C also contains complete Preventive Maintenance Checks
and Services for the Shore Discharge System.
6-2 Major components. The shore discharge system consists of winch with flexible hose winch hydraulic motor,
hydraulic power unit, levelwind, chute, PIG, PIG launcher, PIG receiver, gate, valve, control station, (winch hydraulic
power unit remote switch, shore winch, valves, piping, and start/stop electrical circuitry). Table 6-1 lists the major
components of the shore discharge system, their basic function and location on the barge.
