Stay cool
Maximum uptime starts with cooling capacity
SonicShield is a state-of-the-art ultrasonic anti-fouling technology engineered and designed by H2O Marine, delivering a sustainable alternative to traditional ICAF systems using copper anodes. By applying controlled high-frequency sound waves, SonicShield prevents marine organisms from settling on critical seawater systems, keeping cooling circuits, sea chests, strainers, and box coolers clean and fully functional.
By keeping these systems free from fouling, SonicShield helps vessels stay cool and operate at optimal thermal efficiency, directly reducing energy consumption and preventing performance losses. This continuous, non-toxic protection supports maximum operational uptime by minimising unplanned maintenance, cleaning, and system downtime.
Without chemicals, heavy metals, or consumable anodes, SonicShield offers a low-maintenance, environmentally responsible solution with predictable lifecycle costs. The result is reliable cooling performance, improved asset availability, and uninterrupted vessel operations — allowing shipowners and operators to save energy while safeguarding uptime across all operating profiles.
“Since implementation, we have seen tangible results, particularly a substantial reduction in heavy barnacle growth, even though our vessels operate in tropical waters where fouling is typically severe.”

“Before working with H2O Marine, one of our main challenges was that docking was required for hull installation, combined with the lack of a suitable adapter plate to properly fit curved hull surfaces. We were also actively looking for a reliable alternative to MGPS, specifically to prevent hull growth on our high-speed vessels operating in demanding conditions. What motivated us to move forward with H2O Marine was their clear focus on biofouling prevention without compromising vessel performance. Since implementation, we have seen tangible results, particularly a substantial reduction in heavy barnacle growth, even though our vessels operate in tropical waters where fouling is typically severe. This has had a positive impact on our operations and maintenance intervals. While the overall performance has been satisfactory, Based on the results so far, we would recommend H2O Marine to others in the industry.”
