In Focus: Shipowners save $8bn according to AkzoNobel performance data

AkzoNobel Intersleek savings

Paints and coatings manufacturer AkzoNobel says its performance data has revealed that, over the past 10 years, over 41 million tonnes of CO2 have been saved with Intersleek 1100SR, and the coating has slashed ship fuel bills by $8bn.

The real-world performance data is compiled from ships applied with the international brand Intersleek 1100SR.

AkzoNobel says its biocide-free, foul-release coating ‘revolutionised’ the coatings industry when it was launched in 2013 and has been applied to more than 3,000 vessels since then.

Due to the high performance of the biocide-free technology, demand has risen steeply in the past 18 months as ship owners work to cut CO2 emissions to comply with new carbon regulations and look for proven solutions.

Last year, the International Maritime Organisation announced new carbon targets for the fleet, which include a 20 per cent reduction in emissions by 2030, a 70 per cent reduction by 2040, compared to 2008 levels, and the ultimate goal of net-zero emissions by 2050.

Intersleek 1100SR was the world’s first biocide-free fouling control coating featuring patented ‘slime release’ technology that tackles micro-fouling on ships’ hulls. Now, the company says it’s the optimal slime release for all vessels, even in warm winters and slow steaming and has set the standard for foul release technology in the industry over the past decade.

The technology maintains performance through the docking cycle without the use of biocides. It is said to deliver outstanding macro and micro fouling control with improved static resistance, even in warm waters.

The slime that builds up during docking is released when the vessel travels through the water, therefore reducing drag, improving fuel efficiency and reducing CO2 emissions.

“Our groundbreaking Intersleek range has set new standards for efficiency, performance and sustainability in the marine industry when it comes to biocide-free performance,” says Chris Birkert, AkzoNobel’s marine coatings segment manager.

“Together with our customers, Intersleek has the largest foul release track record, gathered from 20 years of vessel performance data that proves our Intersleek coatings have helped save ship owners $19.6bn dollars in fuel costs and 103 million tonnes of CO2. to help them hit carbon targets.

“This incredible saving includes $8bn in fuel bills and 41 million tonnes of CO2 from Intersleek 1100SR over the past 10 years.”
