 APPENDIX B
LESSONS LEARNED, EXPERIENCES, AND TESTING
B.1 Old tire rims can be used for saddles to support and guide rubber hoses
on ships and piers, to prevent kinking and chafing.
B.2 Where hoses come in contact with abrasive material and may be worn by
chafing, the hoses should be protected by a shield cut from an old length of
hose.
B.3 Dripping of sewage at the ship deck riser can be prevented or corrected
by use of a saddle located about 4 feet from the deck riser, to carry the
weight of the hose and relieve strain on the cam-lock coupling.
B.4 If more than two hose lengths are required for a ship connection
couple hoses prior to passing them to the ship.
B.5 Always have the shore end of the hose secured to a pier fixture to
avoid loss of the hose over the side by the ship's crew.
B.6 During AFFF testing, the fire-fighting fluid is diluted 94 percent and
can be discharged to a barrel with an attached sewage hose, so that the AFF
fluid may be discharged to the sanitary sewer. Boiler cleaning agents (weak
acids) may be discharged in the same way. Discharges of ship-generated
industrial wastes to the pier sewage collection systems, shall be cleared
with the shore support activity on a case-by-case basis.
B.7 Nearly all submarines and some ships cannot flush their lines and the
connecting hoses with salt water. After disconnection from the vessels,
these hoses should be connected to the nearest salt water line on the pier
and flushed with salt water into the harbor for 10 to 15 minutes. This will
prevent having to coil and handle contaminated hoses, and also will
eliminate one uncoil-coil operation.
B.8 Salt water flushing should clean ships' hoses adequately, making it
unnecessary to uncoil the hose for washing at the storage area and then
recoil it for storage.
B.9 Ship-to-shore connections should be made with the shortest possible
length of hose. This cuts down on pulsating and pounding problems. Use of
short lengths of hose from repair operations will facilitate this procedure.
B.10 Lead hoses from ship to shore on a spring line to minimize a heavy loop
filled with water between ship and shore.
B.11 Each activity responsible for operating shore sewage collection systems
should make a salt water flow test of each pier section accepted from a
construction contractor prior to use for the collection and transfer of ship
generated raw sewage.
