Sonihull ultrasonic anti-fouling systems
Zero poisonous environmental legacy
Unlike biocidal coatings and impressed-current systems, Sonihull is low cost, low maintenance with zero poisonous environmental legacy.
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 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.
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 miscropic movement of water also prevents barnacle and mussel larvae from embedding on the surface.
Key Features of Sonihull
Effective bio-fouling without the poisonous environmental legacy of biocides or microplastics.
No drydocking, no through-hull fittings, no expensive Impressed Current Antifouling copper anodes to replace.
No cleaning hard-to-reach areas, extended maintenance intervals, less downtime and reduced running costs.
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%.
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.
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 anti-fouling 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.
SAR Vessel- Gulf Arabian
Vigilant coming out to dry dock in Kuwait, she has been in the water for almost a year (February 2015) and is in a pretty impressive condition. There is no fouling at all.

All pipes pretty clean/clear, bit growth in some but no mussels so obviously Sonihull is working. thank you.
