| Abstract [eng] |
In this Master degree thesis on Fleet technical operation management will be examined the requirement of MARPOL Annex 6, Chapter 4 of the IMO (International Maritime Organization to improve the efficiency of the world fleet with the Energy Efficiency Design Index (EEDI). For many newly built vessels or vessels undergoing major modernization, EEDI must be established at least less than the minimum required by IMO MARPOL Annex 6 requirements. The thesis will describe the importance of EEDI and its impact on the global fleet; described the regulation and requirements of this index. It also reviews technologies that help improve the ships energy efficiency index. The main objective of this energy efficiency design index is to develop a method for calculating the energy efficiency of a ship at the design stage. This index is used as a reference line in terms of efficiency that every new ship project needs to achieve. The energy efficiency design index restriction requirements will be implemented in three steps. At the moment we have stage 1 which started in 2015 and is going to be finished in the end of 2019. The second stage will begin at the beginning of 2020 and will be finished in the end of 2024. Finally the third stage will start in 2025. In addition there will reviewed and the technologies for improving this index. There are the names of technologies that will be reviewed: • Reducing of the ships’ hull resistance; • Moving towards cleaner fuels usage; • Usage of the higher efficiency propellers; • Usage of the exhaust gas heat recovery systems; • Reducing of the ships’ design speed; • Hybrid propulsion complexes; • Solar energy use; • The use of wind energy. The thesis will also include a theoretical modernization of the selected object, which aims to identify the technology required for a ship that was built when EEDI requirements were not regulated. The object of this study is a RO-PAX type vessel for the transportation of rolling and / or rolling cargoes and passengers “VICTORIA SEAWAYS”. This ship was built in 2009 at Marina Di Carrara, Italy, at the “Nuovi Cantieri Apuania” shipyard, it belongs to “DFDS” Company. The survey uses all reviewed technologies in order to improve EEDI to the highest standards. |
