Sonihull: The world’s leading ultrasonic anti-fouling specialist

Wherever there is unwanted marine biofouling. From tugboats to oil tankers, wind farms to fish farms, Sonihull is working with industry leaders to create cost-effective antifouling solutions that reduce drag, cut fuel consumption, increase service intervals and leave no poisonous environmental legacy.

Key Features of Sonihull

Environmentally Friendly

Effective bio-fouling without the poisonous environmental legacy of biocides or microplastics.

Easy Installation

No drydocking, no through-hull fittings, no expensive Impressed Current Antifouling copper anodes to replace.

Less Downtime

No cleaning hard-to-reach areas, extended maintenance intervals, less downtime and reduced running costs.

No Disturbance

Inaudible to humans and marine life with no interference to sonar and electronic equipment.

Lower Fuel Consumption

Clean hull, propellers and rudders can reduce fuel consumption by up to 30%.

Microbial Control

Ideal for bulk storage. Sonihull suppresses Diesel bug and keeps potable water fresher for longer.

Low Power Consumption

At only 3.6 Watt-hours per transducer, Sonihull is ideal for onboard, standby or remote power.

Lower Operating Costs

Can save up to 95% of capital and MRO costs when compared to impressed-current antifouling systems.

Easy System Integration

Compatible with RS232 / RS422 and Modbus communication interface for remote control with critical path fault monitoring.

Biocides are not a long term solution

Ultrasound has already proven its antifouling credentials in the food, brewing and aquaculture industries. By 2026, any marine antifouling system that uses a biocide will have to be resubmitted for lengthy and expensive approvals.

Coating industry insiders expect that many of the current biocide systems will be discontinued before 2026, as demand grows for future-proof biocide-free solutions.

The 2026 deadline for biocide resubmission is approaching.

Prevents biofouling on all surfaces

Sonihull is a complete range of fit-and-forget antifouling solutions for any solid surface that is exposed to raw seawater. From hulls, shafts, propellers and waterjets, to sea-chests, tanks, keel-coolers, box-coolers, pipework, intakes and valves.

Unlike biocidal coatings and impressed-current systems, Sonihull is low cost, low maintenance with zero poisonous environmental legacy.

Headline Figures

Since 2006, over 30,000 Sonihull anti-fouling systems have been installed worldwide, making Sonihull the world’s leading ultrasonic anti-fouling specialist.

Zero environmental impact

0%

No leaching of poisonous biocides, no shedding of microplastics from ablative coatings harmless to marine mammals and fish.

Save on running costs

0%

A fouled hull, propeller, and steering gear will increase drag and can increase fuel consumption by up to 30%.

Reduce capital & MRO costs

0%

Compared to Impressed Current Antifouling Systems. With Sonihull there's no drilling, no welding, no downtime and no costly copper anodes to replace.
