Hull cleaning during navigation
Reduce fuel consumption with In Transit Cleaning of Hulls (ITCH)! A system for cleaning the hull sides while underway.
The hull cleaning system for ships at sea is a system that can reduce fuel consumption through proactive cleaning. It cleans the sides of the hull using the ship's propulsion and the fluid dynamics of water while at sea. Since cleaning is performed in international waters, there is no need to collect dirt. The system consists of the robot body, winch, control system, and brushes, maintaining optimal hull performance without affecting paint thickness or surface roughness. A joint demonstration project with DNV has confirmed fuel savings of approximately 5-16%. **Features** - Cleans the sides of the hull using the ship's propulsion and water fluid dynamics - Maintains optimal hull performance through proactive cleaning - No need to collect dirt due to cleaning in international waters - Brushes have been confirmed not to affect paint thickness or surface roughness - The robot is equipped with a camera that can record the condition of the hull *For more details, please download the PDF or feel free to contact us.*
