Abstract: In maritime economics, ships fuel consumption accounts for the important part of operational expenses and it is straight forward that every ship owner would aim to run their fleet as optimum as possible in terms of fuel efficiency. IMO has developed the Energy Efficiency Operational Indicator (EEOI) that provides information concerning the efficiency of the ships in operation where fuel consumption is the main criteria for the calculation. The reduction of fuel consumption through decreased frictional resistance of hull is one of the most known method in maritime industry to increase operational efficiency of ships. Ship operators are generally making their decisions according to real-life experiences. It is clear that literature needs further studies regarding hull performances with the real-life data even if there will be higher uncertainties compared to laboratory test results. The purpose of this study is to review results of new hull coating technologies for high speed RO-RO vessels and analyze the potentials to decrease fuel consumption as well as speed loss. Actual field data of 8 high speed RO-RO vessels has been studied according to new standard ISO 19030 - Ships and marine technology, Measurement of changes in hull and propeller performance. Results indicate the importance of full blasting for hull performance and a significant fuel savings through decreased speed loss via new technology foul release silicone coatings.
