connection
Á
of the seawater pump. A hose is
used for this purpose with a diameter of 4 inches.
Seawater outlet
The ship−side piping is connected to the seawater
outlet
Â
. Seawater is frequently sprayed into the
exhaust system, see page 42. A hose with a 4 inch
diameter is used to connect to the ship−side piping.
Measuring points for commissioning
For the commissioning process there are
measuring points
Ã
installed at the inlet and outlet
for the seawater (M14x1.5).
Gearbox oil cooler
Cooling water for the gearbox oil cooler is supplied
through the connection
Ä
on the seawater pump.
The gearbox oil cooler’s water supply is marked
with
“
out".
The connection for the cooling water return from
the gearbox cooler is to be installed by the
shipyard on the ship−side piping.
There are 2 possibilities for this:
1. Installation in the seawater outlet downstream
of engine
2. Installation in the seawater injection in the
