heal.abstract	The present diploma thesis aims at carrying out a cost-benefit analysis of the application of main and supplementary means which are meant to improve the vessel’s efficient operation from an environmental and financial point of view. The means that are going to be examined are the following: 1. Installation of Flettner rotors. 2. Installation of Dual Fuel main engine and diesel generators instead of conventional main engine and diesel generators. For each of the means, a cost-benefit analysis for a Kamsarmax Bulk Carrier vessel (abt. 81,000 t DWT) has been made, taking into consideration costs related to capital and operational expenditures, as well as benefits related to energy-fuel saving. Firstly, the introduction of the diploma thesis has been developed while taking into account IMO’s upcoming targets and regulations. In the first chapter, the issue of the greenhouse effect has been analysed with keeping the shipping industry, the consequences on different aspects of people’s lives and the treatment measures that can be adopted in mind. The second and third chapters include analysis of the Flettner rotors and LNG engines respectively. Regarding the Flettner rotors, the operating principle and the regulations that should be followed so that the Flettner rotors can be installed on a ship have been developed.Considering LNG engines which is a wider chapter, the environmental benefits and the type of marine engines operating nowadays on LNG fuel have been discussed. Moreover, the type of LNG tanks currently on the market are presented along with some statistics regarding the field of LNG fueling. Last but not least, LNG fuel bunkering options and the regulatory framework around LNG as a fuel is presented. Later on, chapter five includes the techno-economic analysis that has been used for both the installation of Flettner rotors and the dual fuel main engine and diesel generators, with the results presented in a table format. Finally, in chapter 6 the conclusions arising from the results are discussed. Flettner rotors’ results show that even in the least favorable situation of medium wind, the investment can be proved profitable, while in more intense wind the results are even more positive. On the other hand, the results for the LNG concept are not convincing. It seems that with the current prices of MGO and LNG the investment would not prove to be profitable. Lastly, both the installation of Flettner rotors and the installation of LNG engines are examined with the price of the fuel and the prices spread between different fuels, as a basic factor for the calculations. In a 25-year time framework it will be quite difficult to predict the behavior of the market as new regulations, new technologies and other factors are entering the game.
