heal.abstract	In this master thesis, a total cost of ownership (TCO) model was developed regarding the marine propulsion with different alternative fuels for a Panamax dry bulk carrier throughout its lifecycle. The fuels involved were the conventional as a basis, biofuels B24 and B30 instead of VLSFO, LNG, methanol, LPG, ammonia and liquified hydrogen. Initially, the total cost of ownership was separated into capital expenditures (capex) and operational expenditures (opex) with subsequent divisions. Following that, the global and European regulations that require the reduction of greenhouse gases emissions and the adaptation of alternative fuels and the characteristics of the latter regarding production, emissions and properties were analysed. Technical specifications and details about main engines, gensets, boilers, auxiliary systems, storage and bunkering infrastructure were also assessed. With respect to the methodology section, a Panamax bulk carrier with suitable dual fuel engines were assumed and project guides and engine calculators were utilized for fuel consumption data and GHG emissions. Fuel prices were also assumed to remain fixed for the lifetime of the vessel. Capital expenditures were mostly calculated with data provided by maritime specialists and studies applied in the specific details of the assumptions made in the dissertation. Operational expenditures were formed also with data collected from maritime annual reports, however for some fuels and in certain sections some reasonable estimations were made using the LHV of the fuels for their consumption since ammonia and LH2 marine engines are not available yet for the energy output and size needed. For the estimations about other operational aspects also the availability, hazardousness, properties and current market of the fuels in combination with advises from maritime specialists were made. Additionally, after evaluating the CII rating of each fuel for the panamax bulk carrier the lifecycle capex and opex were calculated and analyzed. The results could not be straightforward since a promising TCO was sometimes associated with a low CII rating which led to an inevitable swift to a greener fuel. Subsequently, a comparison was conducted at last taking into consideration both the straight capex and opex and the environmental ratings of the vessel.	en
