Mothballing the turbocharger
10.1
Taking the engine out of operation for up to
12 months
Condition of engine lubricating oil
The turbocharger normally remains mounted on the engine. Mothballing a turbocharger
depends on the condition of the lubricating oil. No measures are necessary under the
following conditions:
Total acid number (TAN) < 2 mg KOH/g
The engine lubricating oil is replaced by preserving oil before decommissioning and
circulated by the pre-lubrication pump. Any remaining old engine oil will therefore be
flushed away and the bearing sections largely protected against corrosion.
Mothballing measures
WARNING
Handling operating materials and supplies
Swallowing or inhaling vapours of operating materials and supplies or
contact with them may be harmful to health.
Do not breathe in these substances and avoid contact with the skin.
Ensure proper ventilation.
Observe the information in the material safety data sheet for the operating
materials and supplies.
Comply with local legislation.
Wear safety goggles.
Wear safety gloves against mechanical risks.
Wear a respiratory mask to protect against gases.
If the total acid number (TAN) is greater than 2 mg KOH/g, the following mothballing measures
are necessary after taking an engine out of operation:
Dismantle the turbocharger.
The rotor and the bearing parts must be removed by an official ABB Turbocharging service
station and refitted afterwards.
Clean all parts.
Machined, bright surfaces of steel and cast parts must be oiled with anticorrosive oil.
Reassemble complete turbocharger.
Rotor turning in stack draught
If the rotor turns as a result of the stack draught:
