Coating Boasts Fuel, Emissions Savings


A new biocide-free fouling control coating has been launched by AkzoNobel’s marine coatings business, International.

According to the Amsterdam-based company, Intersleek 1000 is the first fouling control coating to be based on its patented Lanion technology, which incorporates bio-renewable raw material from sheep's wool to help deliver enhanced vessel performance.

The biocide-free formula not only means that no biocides will leach into the waters, but it also offers applicators enhanced health and safety benefits, the manufacturer notes.

Development of this new coating acknowledges the differing preferences and operational requirements of ship owners and operators looking to invest in more sustainable hull coatings, says Robert Wong, marketing director for the Marine Coatings division. 

An ‘Ultra-Smooth’ Surface

The long-term fouling control performance of the new coating is equivalent to a self-polishing copolymer (SPC) coating, the manufacturer says. However, when compared with SPC coatings, it reportedly delivers smoother films upon application, which leads to lower hull roughness and improved vessel efficiency.

Being able to maintain an “ultra-smooth surface,” leads to reduced drag and lower fuel consumption and emissions, the manufacturer says.

Service trials indicate that vessels switching from a biocidal SPC coating to the biocide-free fouling control coating were able to achieve fuel and CO2 savings of up to 6 percent, it explains.

“Thanks to Intersleek 1000’s Lanion technology, we can offer an alternative sustainable coating option, which supports the widespread adoption of eco-efficiency technologies while meeting our commitment to developing innovative coatings in a sustainable way,” Wong says.

“This will boost the operational and environmental performance of the shipping industry, as well as improving efficiencies and profitability for ship owners and operators,” he adds.
