Engine and Tank Venting to the Outside Air

Venting of engine plant equipment separately

The various tanks, engine crankcases and turbo-
chargers should be provided with sufficient vent-
ing to the outside air.
MAN Diesel & Turbo recommends to vent the in-
dividual components directly to outside air above
deck by separate venting pipes as shown in Fig.
8.07.03a.

It is not recommended to join the individual vent-
ing pipes in a common venting chamber as shown
in Fig. 8.07.03b.
In order to avoid condensed oil (water) from block-
ing the venting, all vent pipes must be vertical or
laid with an inclination.
Additional information on venting of tanks is avail-
able from MAN Diesel & Turbo, Copenhagen.
