It is not a trivial task for ship owners and shipyards to decide which coating to use or how often the surfaces should be recoated or cleaned based on cost/benefit analyses. SSPA has completed a research project with the aim to gain increased knowledge of the effect a rough surface has on skin friction. This project has also resulted in an interactive tool that can be used to estimate fuel consumption without requiring background knowledge in hydrodynamics. This tool is the “Skin Friction database”, which will hopefully contribute to better surface treatment of vessels, that in the end can reduce costs and emission of greenhouse gases from the maritime sector.
The paper “Comparison of modern keel types for sail boats” was published in late 2017. The study systematically evaluated the hydrodynamic performance of different types of bulb keels. Recently, the paper was awarded with two prizes at the Royal Institution of Naval Architects (RINA) annual meeting. The Institution’s Medal of Distinction and the Austin Farrar Prize.
