Clean Bilge Overboard

The clean bilge overboard pump is used to pump water directly from Clean bilge water tank 18C overboard via the Whitebox.

Before the clean bilge overboard pump can be started to process bilge water overboard we have to ask permission from the on duty officer on the bridge. If we have permission from the on duty officer on the bridge we need a starting time and a starting position to enter in the appropriate log books.
