Biofouling develops hours after a ship is deployed in the sea.

Beginning as a slimy layer, the volume of organisms grows until advanced species like barnacles develop. Biofouling transports viruses, bacteria, algae, amoebae, parasites, mussels and barnacles. It may not be possible to bring a ship in port and remove biofouling without releasing effluent. Biofouling is the main carrier of invasive species along coastlines. ITCH will detach the biofouling mid ocean where it sinks and cannot breed.

Hull grooming

Preventive hull cleaning reduces the risk of transporting species between aquatic biotopes. Grooming must be performed often to work. Only ITCH does not bring the fouling in harbour, eliminating the risk for non-approval of cleaning permits.

Antifouling paint

The primary barrier against fouling is antifouling paint. Biocides like copper repel biofouling. A hard handed in-port cleaning operation can wear the antifouling. Plastics and biocides may then accumulate in the costal sediments. ITCH will only release inactive antifouling paint and not concentrate residue in harbours.

CO2 emissions and CII

CO2 emissions are cut with reduced fuel consumption from a ship with a clean hull.
