Abstract

This paper aims to introduce one of the latest investigations on development of marine antifouling coatings and <br/>also to demonstrate the importance of the type of antifouling coatings on fouling accumulation and ship <br/>resistance/powering. First, marine biofouling and fouling prevention methods are reviewed. A recent research <br/>study (EU FP7 FOUL-X-SPEL Project) concerning a novel and environmentally friendly antifouling coating is <br/>presented and discussed. Next, a case study is carried out to assess the effect of fouling on ship resistance and <br/>powering. A vessel is selected and the roughness on the hull surface induced by different level of fouling is <br/>considered. The increase in frictional resistance and effective power is evaluated for each particular case by using <br/>boundary layer similarity law analysis and experimental data. The results emphasise that the type of antifouling <br/>coatings has a great importance on the amount of fouling accumulation, hence on ship performance especially in <br/>low speeds
