Sonihull expands into South Asia

Sonihull, the world’s leading ultrasonic anti-fouling system, has appointed Aeromarine in Mumbai as an approved dealer for

commercial shipping and offshore installations in South Asia.

Based in Coventry, Sonihull has developed an industry-leading technology that safely prevents marine algae, weeds and molluscs from colonising ocean-going vessels and structures like ships and wind farms. The technology removes the need for poisonous chemicals and microplastics in anti-fouling coatings and can reduce maintenance costs by up to 90%. The company is transforming the way that marine applications are approaching anti-fouling, an industry that is worth about $100 billion annually.

“We are delighted to have appointed Aeromarine, as a distributor in South Asia,” says Darren Rowlands, CEO of Sonihull. “Aeromarine is considered to be one of the leading marine equipment specialists in the region and, with offices all along the Indian coast, has the ability to supply and service all kinds of applications in the region’s maritime sectors.”

From the Aeromarine headquarters in Mumbai, Aliasgar Patrawala (right), Director of Aeromarine Private Limited, said: “I am excited about the potential of this technology on all fronts – easy installation, zero environmental impact and savings of up to 90% compared to impressed current anti-fouling systems. The Indian market can benefit widely with such a solution and the scope of applications is tremendous. It is a pleasure to be working with Sonihull.”

For one of their first installations, Aeromarine fitted a Sonihull system on ‘Ocean Star’ (below), a 31m tug built in 2017 and owned by Ocean Sparkle of Chennai. Sonihull was used to cure persistent bio-fouling problems in the sea chest gate-valve and tank top as well as on the bottom hull plating and the adjacent starboard shipside area.

Fitting is simple. There is no welding, cutting or drilling required and there are no expensive impressed current anodes to regularly replace. The mounting surface is cleaned back to flat, bare metal and the transducer mounting ring is epoxied to the clean surface. Once the resin has set, the transducer is screwed into position to transmit a strong ultrasonic signal directly through the metal surface.

Microscopic ultrasound-induced cavitation disrupts the first stages of the food chain without damaging the surface. This prevents the build-up of algae, slime and bigger more complex organisms. The system is silent, self-monitoring and the movement of water on the protected surface prevents the adhesion of juvenile barnacles and mussels.

“In similar commercial applications, operators are saving up to 90% of their capital and maintenance costs when protecting raw seawater equipment like box coolers and sea chests with Sonihull instead of impressed-current anti-fouling systems,” added Rowlands. “Sonihull is a zero-harm solution. There are no poisons, or biocides leached into the marine environment, no microplastics are shed from ablative coatings and no toxic metallic ions are left in your wake.”
