Sažetak
The reliquefaction system installed onboard of the LNG carriers is very significant, which due to its unavailability can cause substantial costs to the shipowner. In this paper, the cost estimation has been made to make optimal decisions about maintenance strategies. Reliability model and cost estimation are made by the Markov model, and implemented on real LNG shipscenario, based on the boil-offgas reliquefaction system. A large LNG Carrier with the direct drive slow-speed diesel engine propulsion is analyzed from the maintenance standpoint, and optimal costs are calculated, depending on chosen maintenance strategies. While choosing many states and components for inputs in the Markov model, it is shown that results don’t necessary tends to be more accurate with a complex model, compared with the simplified one.
