Whether it is steam powered or has an internal combustion engine as the
main engine of propulsion, a ship without a boiler is unimaginable; somehow a
boiler, which is indispensable on ships is needed. Boiler, one of the most
important ship auxiliary engines, is used for several purposes that consist of
heating of fuel tanks, machinery equipment and accommodation. Many problems can
arise in boilers which are designed to work with main engine exhaust gas so
that the waste heat can be used in order to match expectations of energy
efficiency requirements. When ship systems are analyzed, it is understood that
many systems are related to each other. If there is a problem with the boiler
many systems will be affected and many problems will be encountered. Therefore,
this study provides a fuzzy DEMATEL (Decision Making Trial and Evaluation
Laboratory) method to assess most common critical operational faults in marine
boilers. The DEMATEL method gives chances to identify and analyses the
important faults of marine boiler with respect to cause effect relationship
diagram. Likewise, fuzzy sets get through with the uncertainty in decision
making and experts comments on DEMATEL. When the results are examined, it is
understood that “boiler takes excessive time to reach pressure” is important in
terms of the reasons. When the effects are examined, it is seen that the most
important effect is “leakage from pipes or valves”. The acquired results of the
research will contribute to ship boilers operational safety and prevention of
dangerous machinery effects.
