After CLOSING OWS 1, the OWS will continue to backflush, sending trapped oil along
with the flushing water to the Oily Waste Tank until the flushing water is secured. Ob-
serve the Oily Waste Tank TLI to ensure that the Oily Waste Tank is not filled with
3. Observe the pipe end of OWS-1 for flushing water to be discharged to the bilge. When the flushing water is
discharged to the bilge, the OWS and all inlet piping are filled. Close OWS-1.
MANUAL BACKFLUSH SHUTDOWN
1. Return all valves from table 2 to the CLOSED position.
2. Notify the maintenance supervisor that the OWS has been backflushed.
The OWS is designed to operate at inclinations up to 22.5 degrees. Angles greater than that could cause
remixing of separated oil and water, degrading performance. Violent side-to-side or fore-and-aft motions could
also degrade performance. For this reason, the OWS should only be operated during relatively calm sea states
If the secured OCM will be exposed to freezing temperatures, remove and drain the sampling/sensor assembly
(WP 0015 00).
