The scope of this thesis is the application of Liquefied Natural Gas (LNG) as fuel for the propulsion of Ro- Pax vessels.
Initially, this thesis cites the current and emerging international and European legislation in order to control the air pollution caused by the exhaust gas emission of marine engines and its impact on the climate change, and then analyzes the dynamics of LNG as tool to achieve the above objectives.
The thesis continues in its analysis, focusing on the potential use of LNG as fuel for the propulsion Ro-Pax ships and on its application and expediency in the Greek short see shipping. In addition, the study analyzes the necessary arrangements in order to have a sufficient supply of LNG available for the ships, the supply chain of LNG, starting at the production of the gas to the final utilization in the ships, factoring in the cost indicators associated with this use and the specific decisions and conditions necessary to the development of LNG as a main marine fuel for propulsion.
The study proceeds to evaluate the costs of converting Ro-Pax ships from diesel fuel to LNG and analyzes the possibilities of supplying LNG consuming ships to the port of Piraeus. Finally, the main conclusion of this thesis is that any investment in the use of LNG as a marine fuel seems to be attractive under certain conditions, particularly when ships are operating in short sea shipping.
