Abstract

Batteries could be the near-term solution to the increasing Green House Gas Emissions problem and could also be a part of the future of the marine industry. If their role as storages of energy was combined with the production of "green" electricity, batteries would be an alternative to the traditional fuels with zero environmental footprint and thus a "green" solution. This study is investigating the reliability of a ferry diesel-electric propulsion system, after a multi-annual operation. The Dynamic Fault Tree Analysis method is used to analyse the propulsion system and detect any system failures and the components that cause them. After the analysis is complete a maintenance table is created for the least reliable components of the systems describing the approximate operation hours that when reached the component should be inspected and get replaced or repaired.
