Sonihull ultrasonic antifouling systems

  • Zero poisonous environmental legacy

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

  • Protects inside-and-outside

    From hulls, shafts, propellers and waterjets, to sea-chests, tanks, keel-coolers, box-coolers, pipework, intakes and valves.

  • Complete range of solutions

    Sonihull is a complete range of fit-and-forget ultrasonic antifouling solutions for any solid surface that is exposed to raw seawater.

How it works

Sonihull systems produce multiple bursts of ultrasonic energy in a range of targeted pulse frequencies.

These pulses are transmitted through the material that the transducer is attached to.

The ultrasound produces a pattern of increasing and decreasing pressure on the surface of the material.

Increasing and decreasing pressure

The ultrasound produces a pattern of increasing and decreasing pressure on the surface of the material. In a process called non-inertial cavitation, microscopic bubbles are created during the reduced pressure cycle and are imploded as the pressure increases. The microscopic agitation has a cleansing effect which destroys surface algae.

The benefits

Disrupting this first link in the food chain keeps the surface clean and makes it a much less inviting habitat for larger organisms that feed on the algae.

The microscopic movement of water also prevents barnacle and mussel larvae from embedding on the surface.

Key Features of Sonihull Ultrasonic Antifouling

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.

Testimonials

I want to thank you for your advice to install aboard my ship two SoniHull DUO… I am, after one year, really very happy with those devices. My ship, a 65 Ft steel trawler, has stayed one full year in Brunswick Landing Marina. Here everyone sends a diver every two months for cleaning his hull off the growth, so I have asked the diver to check my hull, after one year without cleaning… The guy was really amazed by the fact that my hull was still perfectly clean… Except for some barnacles on the shafts and propellers, so my only regret is not to have installed the sonic system for the shafts as well. This system is really great and super-efficient. Thanks again for this product.

Pierre – Brunswick Landing Marina, USA

After the first week, a noticeable difference could be seen, by the end of the 4th week, the results were conclusive. The vessel fitted with Sonihull had little or no growth over the entire hull, while the other vessel was found to have so much growth the vessel struggled to get on the plane. As a result of this test, Sonihull will be included in all future standard project specifications.

Finally, I am proud to inform you that the first Sonihull antifouling system has been installed on one of the SAR vessel without any problem. We have installed two transducers on the intake of the water jests, one between engine & generator and another one in accommodation. After finding this project successful, many other vessels will be in the row.
