shore crew drains the defective hose into the pier riser as well as possible.
Then they bend a heaving line about the pier end of the hose, close the hose
riser valve, disconnect the pier end of the hose from the riser, and suspend
the pier end of the hose over the side of the pier, using the line.  This
makes it possible for the ship to flush the defective hose with salt water
while the sewage spill on the pier is being cleaned up. Should the pier
sewer riser be under back pressure, the procedure outlined in 8.1.3 shall be
followed.
When both the sewage spill cleanup and salt water flushing of hoses
have been completed, the shore crew recovers the pier end of the hose. The
ship's crew disconnects the ship's end of the hose and hands it down to the
shore crew via a heaving line.
As the defective hose passes from ship to pier, it may be handled by
powered hose reel or by manual procedures.  The ship is reconnected to the
pier sewer by means of a sound, clean sewage hose, following the standard
connection procedures. Riser valves are opened on both the ship and pier.
The ship's CHT system then is placed in the pump-ashore mode, and pumping of
sewage into the pier sewer is recommenced.
After cleaning the spill area and replacing the ship's leaking sewage
hose(s) the shore crew departs, taking the defective hose(s) with them on
the transport vehicle to the sewage hose repair area.
