Biofouling accumulation on a ship’s hull has a direct impact on fuel consumption and associated greenhouse gas (GHG) emissions and may pose a biosecurity risk due to the presence of non-indigenous, potentially invasive aquatic species.
The antifouling system (AFS) is designed to protect the underwater surfaces from biofouling accumulation. Underwater inspections (UWI) of ships are typically carried out to monitor and verify the condition of the underwater hull and the AFS.
Recipients of UWI reports are reliant on the quality of information provided to make adequate decisions relating to hull performance, AFS condition and performance, biofouling management and associated risk assessments. Consistent and good quality reporting is key to effective underwater hull condition record-keeping and management.
