10.2 Taking the engine out of operation for more than
12 months
If the engine is taken out of operation, the following variants are possible with regard to the
low-pressure and high-pressure stage:
Low-pressure and high-pressure stage remain attached to the engine.
The casings of the low-pressure and high-pressure stage remain attached to the engine,
the rotor and the bearing parts are dismantled by an ABB Turbocharging Service Station
and stored separately.
Low-pressure and high-pressure stage are completely removed, either as whole units or in
single parts.
For the measures always necessary for preparing the low-pressure and high-pressure stage
for mothballing, see section Taking the engine out of operation for up to 12 months, subsec-
tion Preparations for mothballing.
If the low-pressure and the high-pressure stage remain attached to the engine, see section
Taking the engine out of operation for up to 12 months, subsection Rotation of the rotor in the
stack draught.
If the complete low-pressure and high-pressure stage are removed or if the low-pressure and
high-pressure stage are reassembled from their individual components:
Seal all openings of the low-pressure and high-pressure stage with paraffin paper and
wooden lids.
Only dry rooms with 40-70 % atmospheric humidity, in which no water condensation can form,
are suitable for mothballing.
State of the mothballed low-pressure and high-pressure stage
Check the low-pressure and high-pressure stage parts annually for corrosion
If there are signs of rust: Thoroughly clean parts and renew corrosion protection.
