Fluropolymer paint technology claims 9% emission savings

09 March, 2011

A report from one of the shipping industry’s leading research bodies, Professor James Corbett’s Energy and Environmental Research Associates, has proven that the eco-efficiency benefits of Fluoropolymer Foul Release Technology when applied to tanker, bulk cargo and other vessel types can reduce GHG (greenhouse gas) and other emissions by an average of 9%. The report, which was today welcomed by the United Kingdom’s leading environmentalist Jonathon Porritt and Julian Brazier TD MP, chairman of the All Party Maritime and Ports Group underlines the savings achieved using Fluoropolymer non stick technology that has excellent resistant to marine fouling.

Over 400 vessels in the commercial fleet currently use Fluoropolymer Foul Release technology for marine applications, patented by International Paint, making it one of the most widely used eco-efficiency technologies in the shipping market.

The report, on products manufactured by International Paint, the world’s largest marine coatings supplier and part of AkzoNobel, analysed the latest fuel consumption data of three vessel types when coated with Fluoropolymer Foul Release technology;Prem Divya, a single engine 21,126 horsepower (HP) tanker,Ikuna, a twin engine 3,400 HP bulker and five identical post panamax container vessels, three of which were coated with TBT free polishing antifoulings and two with Fluoropolymer Foul Release technology.

The results showed that fuel consumption (and therefore the vessel’s emissions) was reduced by 10% on thePrem Divya, 22% On theIkunaand by 5% in the container vessels (based on all five ships carrying a comparable load). The report states that if similar fuel efficiency results were realised by all tanker and bulk cargo vessels within the commercial fleet that: “annual fuel oil consumption could be reduced by roughly 16 million metric tons (MMT) per year, fuel expenditures could be reduced by $4.4 to $8.8 billion per year, and nearly 49 million MMT of CO2 emissions could be avoided annually’1 .

Significantly, the report showed that reductions in CO2 are achieved at a negative cost, whereby the avoided emissions are coupled with economic benefits to the ship owner. For example, thePrem Divyadelivered a total annual fuel cost saving of $251,000 based on a 2009 average bunker price ($387 per tonne). While Fluoropolymer Foul Release technology would cost $645,000 more over a nine year period than a biocidal alternative, if this figure is deducted from 2009 bunker costs and projected over the same time period, the owners of `Prem Divyawould save $1.614 million2. If current (February 2011) bunker prices of $640 / tonne were used for the calculation, the annual savings would be $415,000 and the projected net savings over 9 years would be $3.09 million.
