The HISMAR (Hull Identification System for Marine Autonomous Robotics) is being developed as a moss cleaning system for ships. It is known that the presence of marine growth on the hull can increase drag and thereby slow down the ship. This robotic system, attached to the hull, will vacuum clean the hull of the ship along a predetermined path and thus contribute to better fuel efficiency by reducing drag.
What’s Innovative: The HISMAR makes use of a hull map with all the contour details. The system subjects the hull to a pressurized jet of sea water and the slime is then collected in the main chamber, where the water is filtered and released into the sea. This process makes sure no pollutants are washed back into the water body.
Watch This: It can be a pain if marine growth on the hull of a ship has to be cleaned manually every single day. Automation is the way to go and the HISMAR realizes this objective. The obvious environmental and economic benefits make this concept highly desirable.
