Australian Government gave an award to GRD Franmarine an accelerating project grant work A$1 million in November 2015. Finally, GRD Franmarine will launch the first full scale commercial hull cleaning unit this year in July.

The focus of the development is to get the engineering right. The vortex created by the contactless blades and on-board pumps is enough to form the cleaning pods to the ship’s hull making a negative water pressure vacuum seal preventing possibly harmful biofouling escaping into the surrounding environment.

The cleaned debris is pumped to the surface where it enters a real time, multi staged filtration system. Then, this separates all solid particles more than 15 micron while the remaining filtrate is passed through an ultra violet radiation disinfection unit, before it goes back to the ocean.

GRD Franmarine is incorporating the latest developments into the final design. They will then move to the next stage of development including automation with in-water survey capability and ultrasonic hull plate thickness measuring equipment.

Hydraulically powered hull cleaning unit fitted with rotating discs will be used as the main underwater cleaning tool. The discs will be fitted with conventional brushes for glass or epoxy based coatings or a revolutionary new patented blade system to remove marine biofouling without even damaging the antifouling paint. The company will utilize innovative solution to provide in-water cleaning in a way that causes no harm or risk to the environment.
