Innovative coatings offer quick ‘return on investment’

International Paint, part of AkzoNobel, has pioneered the development of ‘fluoropolymer foul release’ technology, which produces fuel savings and associated emissions reduction of up to a claimed 9% as well as improved service speed. To date over 400 vessels are now using this technology, branded Intersleek 900, as a means of improving both operational and environmental efficiencies.

“If 400 vessels were using sails, solar power, or any other complex, high profile technology, the industry would be lauded as one of the world’s most environmentally progressive transport industries,” says John Wilsher, market manager, Intersleek, International Paint.

“The reality is that it is the simple, proven solutions that are already making a significant impact, without necessarily receiving the recognition they deserve at an international level.”

Wilsher continued: “It is becoming increasingly clear that ship owners and operators will struggle to fully embrace complex technologies that require specialist skills to operate and often engender high maintenance costs. The reality is that fluoropolymer foul release technology is a quick win for the industry, and a great example of how a simply applied technology can have a huge impact on improving efficiency and reducing emissions. If Intersleek 900 was applied to the whole commercial fleet, CO₂ emissions could be reduced by almost 100 million tonnes every year. Few, if any, technologies in other sectors can say that.”

Fluoropolymer foul release technology is claimed to be the most advanced ‘next generation’ hull coating within the shipping industry. The company says the 9% reduction is a conservative estimate with some vessels realising significantly more and represents efficiencies gained over extended periods. The new coating technology also provides benefits at the next dry-docking in relation to the treatment and disposal costs of wash water and blasting abrasive, as well as the use of less paint, further reducing costs and minimising downtime. Also, for the first time, the technology enables vessels that operate at lower speeds (bulk carriers, tankers, and container feeder vessels) to benefit from the environmental and cost efficiency benefits of foul release coatings.
