Operation with damaged turbocharger
15.4.1 General
In case of a serious breakdown of the turbocharger, a blanking
device can be fitted according to the instructions below, see also
turbocharger manual, section 06. In an emergency situation like
this, the engine can be temporarily operated at max.20 % output.
Thermal overload is a limiting factor on the diesel engine.
Therefore, the exhaust gas temperatures must be carefully
watched during operation with a blanked turbocharger.
Note!
The exhaust gas temperature after the cylinder head must not
exceed 500°C.
A marine engine can in emergency cases for a short period be
operated with only the damaged turbocharger blanked, as re-
quested by the classification societies.
In such case, the damaged turbocharger shall be blanked ac-
cording to below mentioned instruction.
Wärtsilä strongly recommends both turbochargers on a V-en-
gine should be blanked also at above mentioned emergency cases.
In case only the other turbocharger in a V-engine is blanked,
both bellows (at air side) must be removed.
15.4.2 Mounting of blanking device
1 Remove insulation dishes
from turbocharger(s).
2 Remove the bellows (1)
between turbocharger(s) and
air cooler housing, see Fig 15-1.
Note!
In a V-engine, if one of the turbochargers is to be blanked, both
bellows (at air side) must be removed.
3 Mount the screen plate(s) (2)
on the flange connection of
the air cooler housing, see Fig 15-4.
4 Remove the silencer
or air suction branch.
5 Disconnect the cable for speed sensor(s).
6 Remove the locking plate
for the lubricating oil connec-
tion pipes. Press the connection pipes downwards. On a V-en-
gine, remove the lubricating oil connection piece.
7 Mount the lifting equipment
and open the nuts (8). Re-
move the compressor casing.
