The roughness of the surface of the hull is one of the major factors that contribute to the overall fuel consumption of the vessel. Measurements of the hydrodynamic drag of different commercially available antifouling coatings have shown that surface roug hness between different antifouling systems does not vary to a large extend . However, the different antifouling systems on the market do not perform equally over time. The slime will be different over different antifouling, or biocide free surfaces. Grow th of slime and macro organisms will change the condition of the surface. Slime will start to build up as soon as the surface is immersed into water. It is not always visible for the eye but its existence can be recognized measuring the drag of the surfac e. Factors influencing the amount of growth on the surface are the climate the vessel is travelling in and the speed of the vessel, the time the vessel is not moving due to loading and unloading procedures, and incidents that cause damage on the surface. Ship owners that chose the wrong antifouling solution for their needs or postpone necessary cleaning or repair of the hull may have to pay a higher price on fuel costs later due to a higher fuel consumption caused by a high surface drag. Higher fuel cons umption also means higher emissions of CO2, SO2, NOx and particles to the environment. The idea behind the OPTIFOUL project is to develop a holistic approach to give ship owners recommendations on which type of antifouling system they should use on their vessel depending on the speed the vessel is travelling in and the climate zone the vessel is operating in. Recommendation for optimized cleaning procedures and repair procedures will be developed which opens new possibilities for saving fuel, reducing emi ssions from shipping and hence reducing the effects of shipping on the world climate.
