The fishing boat treated in this case mainly sails in the North Sea: salty, fouling sensitive waters. The vessel has a seawater cooling system consisting of three box coolers (one PS, two SB).
The skipper had been experiencing cooling problems for some time, for which he was looking for a solution. Hard growth settled between the cooler bundle every time, causing cooling problems: the flow through the cooler was blocked.
This study describes what the problems were for the vessel, why it chose Ultrasonic Antifouling and what the result is after 31 and 23 months.
