Sažetak
Biofouling, which is the accumulation of various marine organisms on a ship hull, is a very serious problem from both the economic and environmental point of view. It may cause a significant increase in ship resistance and consequently increased fuel consumption and CO2 emission, while reducing the overall hydrodynamic performance of the ship. In this paper, an economic analysis of ship biofouling is performed on a handymax bulk carrier. An increase in ship resistance due to biofouling was determined for different hull surface conditions. The main costs related to the ship hull biofouling were also estimated. The profitability of applying antifouling coatings were investigated in terms of resistance, fuel consumption and CO2 emission. It is shown that biofouling management could be an effective tool in improving energy efficiency and reducing harmful gas emissions. However, the harmfulness of most of the antifouling coatings on marine organisms should also be taken into account.
