Retrofitting existing ships with "greener" technologies currently has become common practice due to different economic and environmental considerations. This research was sparked by the need for the policy makers and ship owners to evaluate the economic, emission and environmental performance of the different available retrofit solutions. For the policy makers, the choice of appropriate retrofit solutions to support is welfare-based, while for the ship owners the industrial-economic aspects are the most important. In practice, viable policies need to balance the interests of both sides. The research uses a three-stage approach to examine the performance of the retrofit solutions. In the first stage, an aggregate simulation model is developed. It allows testing various scenarios that simulate the introduction of retrofit solutions on the European scale. In the second stage, the simulations are run to test the impacts of such currently often discussed technologies and practices as dual-fuel engines, wind propulsion, LNG-powered generators, speed reduction, variable speed operation of propeller, voyage optimization, SCR systems and scrubber systems. The third stage of the research focuses on the assessment of the impacts. It allows comparing the different retrofit solutions based on economic, emission and energy performance. The comparison of the performance of different retrofit solutions enables the choice of the best-performing technological option. The results of this research are most relevant for the ship owners and for policy makers, but other stakeholders might be interested as well. For ship owners, this research shows which retrofit solutions are economically viable and worth considering. For policy makers, this research shows the welfare benefits and costs for ship owners of the tested retrofit solutions, which is applicable for development of efficient and viable policies.
