Engine room ventilation
24
Air ducting, general
The openings for the inlet and outlet of air are to
be arranged such that a purging affect is created,
i.e. the whole engine room is provided with a flow
of air.
Fresh air inlet to engine room
Fresh air should enter along the side of the hull at
as high a position as possible ahead of the engine
room.
À Direction of travel
Á Hoses to engine room
 Air baffle
It is possible to optimise the volume of the air flow
by shaping the air supply duct to optimum flow
effect and by utilising the air stream produced from
forward motion.
Caution:
Water spray and splash water must not be
allowed to reach the engines!
Water ingress would lead to the total loss
of the engine!
A Free cross−section

Ä Air duct
Å Side of ship
The free cross−section A of the air inlet is related
to the narrowest point of the complete air supply
route. It is dimensioned according to the air
requirement of the engines in accordance with the
table on page 23.
Air should enter the engine room at as low a point
as possible between the ship’s sides and the
engines.
Air outlet from the engine room
The air outlet should be located opposite the inlet,
i.e. at the back of the engine room and as high as
possible.
