Antifouling performances of some sco-friendly biocides

Artificial surfaces exposed to seawater are covered by marine fouling organisms. This process is known as ?Biofouling?. When artificial surfaces are considered as ships? hull, the biofouling processes result in undesirable consequences such as increased fuel consumption, CO2 emission, friction and decreased maneuverability and speed. Many attempts have so far been done to prevent biofouling process occurred on ships? hull. These processes are called as ?Antifouling?. There are a lot of different strategies and also paint formulations for ships? hull. However, very limited solutions, strategies and also commercial products have been available for marine propellers. Self-polishing percentages of an eco-friendly commercial product, PROP PROTECTOR (lanolin based material), developed for preventing biofouling processes on propellers? surfaces were investigated dependent on temperature, rotary rate, and fibre reinforcement in the present thesis. According to results, fibre reinforcement remarkably increased the self-polishing resistance of the lanolin based material. Field test results carried out in marine eco-system also confirmed the laboratory experiments. In conclusion, the quality of the commercial product, PROP PROTECTOR, can be developed by adding special fibres and fibre reinforced lanolin based material which might be used in the warm waters.
