\ua9 2016: The Royal Institution of Naval Architects. In recent years, stricter regulations have been applied to ships operating in international waters and especially in Emission Controlled Areas (ECAs). These regulations require the shipping sector to reduce sulphur content of fuel to 0.1% while trading in ECAs and to 0.5% globally by 2020. To respond to these challenges, the shipping sector is exploring a range of mitigating measures and technologies to control emissions, including novel methods of powering ships using clean alternative fuels. Natural gas has proven potential as a fuel and this study proposes a novel approach using Solid Oxide Fuel Cells (SOFC) utilizing the Boil-Off gas from the cargo tanks of LNG vessels. The proposed SOFC power plant demonstrates 49% electrical efficiency and when combined with a Gas Turbine, the hybrid power plant is able to achieve 72% electrical efficiency. The economic viability of this study under various scenarios was further investigated
