Sonihull could save up to 408 million tonnes of CO2
Sonihull could save the maritime industry up to 408 million tonnes of carbon dioxide, says director Darren Rowlands.
Anti-fouling systems firm Sonihull’s managing director Darren Rowlands made the bold claim at the Society of Maritime Industries annual conference in Newcastle upon Tyne, of which the firm was a gold sponsor.
Sonihull’s anti-fouling technology could save millions of tonnes of CO2, the firm claims
Sonihull’s technology uses ultrasound to keep surfaces clear of algae, weeds and barnacles – which reduces drag, fuel burn, CO2 emissions and maintenance costs, the company says.
“Taking propellers in isolation, it has been estimated that if Sonihull prop-protection systems were fitted on every commercial vessel in the world, global ship emissions would be reduced by between 160 and 408 million tonnes of CO2 every year,” said Rowlands.
“With fuel savings alone in large ships, the prop protection systems are paying for themselves within weeks, even before factoring in the reduced prop polishing and maintenance schedules. Our systems are networkable and can be used to protect stationary structures like wind farms and oil rigs too.”
In March 2021, Sonihull signed an agreement with Norwegian maritime technology group Kongsberg Maritime to be its sole supplier of ultrasonic anti-fouling systems for the company’s entire range of Kamewa waterjets.
