Air bleeding

In order to protect the inside of the
installation trunk against corrosive
attacks, the air bleeding system must
be operational. This system consists
of a small air bleeding cock on the
top of the mounting flange and a pipe
leading up and above the sea water
level. The pipe allows air to escape
from the trunk.
The air bleeding system must be
checked after the ship has been
docked. Observe the following
procedure.
1 Ensure that the valve on the air
bleeding cock is open.
Inspect the pipe, and ensure that
2
the top of the pipe is open.
3 Listen to the top end of the pipe.
If the ship is moving, you should
be able to hear the water inside
the pipe.
