Underwater Hull Cleaning is the process of cleaning the underwater portion of a ship's hull. The hull often becomes covered with marine organisms such as barnacles, algae, and other types of marine life, known as biofouling. This biofouling can increase the ship’s drag as it moves through the water, leading to higher fuel consumption, reduced operational efficiency, and increased carbon emissions. Therefore, regular hull cleaning is essential to maintaining the vessel’s performance and reducing operational costs.
