The study demonstrates the environmental performance and relative cost of the three coatings.
Not surprisingly, it is International Paint’s premium Intersleek®900 fluoropolymer foul release coating which comes out well ahead of the other two products.
The key output from the study was as follows:
- Overall fuel saving of 39,420MT over 15 years ($17.7M @ $450/MT for HFO)
- Overall CO2 reduction of more than 125,000MT over 15 years
- Reduced dry-dock times and costs
- Zero biocide emission into the marine environment
Off-shore global warming potential CO2 equivalent release from vessel activity:
* at the time of analysis - now up to 9% reduction.

As far as results are concerned, Boren is convinced of the study’s benefits. From now on, International Paint’s sales executives will be able to explain to customers how the project was undertaken and what conclusions were reached.
They will be able to point to third-party confirmation of procedures, thereby authenticating robust results on the lifetime environmental profile of products.
For those ship owners and operators who have noted that their own customers are increasingly concerned about these issues, this could provide a useful additional marketing tool for them.
Furthermore, Boren believes that the results will also be applied internally in a research and development context. Sensitivity analysis can reveal the variables that potentially have the most environmental impact and this information should prove valuable in the formulation of new coatings.
