Abstract

Recent high fuel prices and global economic recessions have driven shipowners to turn their attention to saving operational costs of their ships. For this reason, a variety of energy saving solutions has been developed and proposed in order to improve energy efficiency of ships. In addition, IMO have also proposed the best practices for energy saving solutions for existing ships through the SEEMP Guidelines. However, these proposed energy saving solutions (i.e. CO2 abatement solutions) do not give sufficient reliability due to the uncertainties of various parameters surrounding ships. These uncertainties may have a significant impact on effectiveness of individual energy saving solutions to a great extent, which include future fuel prices, mutually exclusive solutions, enforcement of SOx emission regulations, financial returns on investment of solutions. At present, these uncertainties prevent shipowners from employing the energy saving solutions. In particular, small companies suffer from lack of human resources and technical expertise in employing energy saving solutions to their ships. In this context, this dissertation analyzes reliability and availability of individual energy saving solutions for existing ships through analyzing specific challenges and effectiveness when implementing each of solutions. Finally, this dissertation proposes feasible measures to facilitate implementation of energy saving solutions.
