Within this project the problem of biofouling (growth of marine organisms) on ship hulls is targeted. The method of hull cleaning, already in use by shipoperators today is to be optimized considering frequency and force. The required knowledge about the biology present on the ship hull will be reached by characterization of biofouling communities and their attachment strength. Further will friction on the vessel created by biofouling be measured and modelled. The project will also work towards a reduction in impact of hull cleaning on the wear of antifouling paint.
