Performance prediction method for fouled surfaces

Increase in ship energy efficiency is one of the main goals set by the International Maritime Organization (IMO). In this sense the IMO identified the significance of the control and management of the hull fouling. The weed or grass stage is often seen as the beginning stage of the ship hull fouling, while the effects of soft fouling on the ship resistance and propulsion characteristics as well as on the fuel oil consumption are mistakenly underestimated. A new method for the assessment of the effect of fouling on the ship resistance and propulsion characteristics is proposed. The applicability of the proposed method is shown by comparison of the obtained resistance and propulsion characteristics using this method and Computational Fluid Dynamics (CFD) approach. Within this paper the effect of soft fouling on the ship energy efficiency is evaluated. Utilizing the proposed method, the increase in the fuel oil consumption and the emission is determined for handymax bulk carrier on the route Halifax-Rotterdam for certain surface conditions. The potential benefits of the hull and the propeller cleaning are highlighted from both an economic and environmental point of view. On the observed route the potential savings in the fuel oil costs could be up to 38000 $, while reducing the CO2 emission up to 327 t.
