Unexpected problems may be found during a top overhaul. Plan to correct these problems, if
necessary.
Buildup in the cylinders from excessive oil consumption
Buildup in the cylinders from contamination of the gas
Plugging of the intercooler from coolant that is poorly maintained
Plugging of the intercooler from contamination of the inlet air
Degradation of the oil cooler from hydrogen sulfide in the gas
5.3.2.3 Overhaul (In-Structure)
Scheduling an In-Structure Overhaul
Generally, an in-structure overhaul is performed for every second top overhaul. Scheduling an
in-structure overhaul normally depends on the following three conditions:
An increase of oil consumption(Oil consumption≥1g/kw·h)
Power reduction ≥10%
F
uel consumption rise ≥10%
Each individual condition may not indicate a need for an overhaul. However, evaluating the
three conditions together is the most accurate method of determining when an in-structure
overhaul is necessary.
Periodically measure each of the three conditions. The first measurement should occur during
the engine commissioning. This establishes a baseline for future measurements. Additional
measurements are scheduled at regular intervals in order to determine a schedule for the next
in-structure overhaul.
Note!
These indications do not require an engine to be shut down for service. These
indications only mean that an engine should be scheduled for service in the near future.
If the engine operation is satisfactory, an immediate overhaul is not a requirement.
Note!
The generator or the driven equipment may also require service when the engine
overhaul is performed. Refer to the literature that is provided by the OEM of the driven
equipment.
In-Structure overhaul
An in-structure overhaul includes all of the work that is done for a top overhaul. Additionally,
some other components that wear are replaced. The condition of components is inspected.
