Biofouling Management: Regulation or Business Edge
2023 IMO BioFouling Management guidelines provide structured procedures for the prevention of the transfer of Invasive aquatic species from ship’s hull, in addition different local regulations are in place (Australian, New Zealand) or being discussed (Norway).
Shipowners face different challenges in complying with these different regulatory requirements: local inspections, record of cleaning, where to clean, how, effect on coating, cost, Biosecurity versus GHG reduction etc.. The balance among regulatory, environmental and market drivers is not an easy one to reach, and inappropriate interpretation of the guidelines or good practices selection may lead to undesired consequences; it can create additional fuel cost and GHG emissions increase. To avoid that, shipowners apply different methods/strategies to reduce Fuel Consumption (hence GHG emissions Energy Efficiency improvement) through good practices related to Biofouling Management. The present paper will review the practical implementation of the biofouling management guidelines 2023 and some of the strategies that shipowners are adopting to minimize biofouling impact on their fleets; it will also present the interactions among Biofouling and CII.
