Combatting biofouling: A costly challenge for global navies

Biofouling is a costly adversary draining global navies billions of dollars per year. These costs encompass addition fuel costs and unplanned maintenance. Additionally, marine growth can impact platform operational capabilities. Biofouling can commence in a mere 15 minutes on hard surfaces exposed to raw seawater, beginning with slime accumulation, and rapidly advancing to hard calcareous fouling.

Eco-friendly Ultrasonic antifouling: The solution for marine prevention

The Sonihull Ultrasonics antifouling system uses ultrasound to prevent marine growth on hulls and structures without biocides or microplastics. It disrupts biofouling with non-inertial agitation, deterring barnacles and mussels. Suitable for hulls, sea chests, box coolers and more, it offers a low maintenance, eco friendly alternative to traditional coatings.
