Glass flake polyester (GFP) coatings offer more than 30 years’ maintenance-free corrosion protection at the splash zone for offshore assets, according to a new independent report from classification society DNV
The study shows that Baltoflake, a GFP solution developed by leading coatings manufacturer Jotun, provides decades of protection for offshore wind substructures and reduces lifecycle costs by up to 50 percent.
The high-performance coating is ideal for deployment in the offshore wind sector, where strong corrosion resistance and excellent mechanical properties are required.
DNV inspected a section of jacket from a North Sea oil platform which was installed in 1972 and decommissioned in 2020. Jotun’s Baltoflake coating was applied to the platform in the late 1980s and, despite over 30 years’ exposure to the North Sea’s harsh environment, analysis revealed that the coating at the splash zone was intact, still smooth and showing no signs of delamination.
Ismail Tan, Global Category Manager at Jotun explains: “By partnering with DNV on this report, we now have the relevant in-field data required to demonstrate Baltoflake’s full asset lifecycle protection performance.
“Baltoflake removes the requirement for offshore wind developers to undertake expensive repairs or replacement due to corrosion. By reducing overall maintenance costs and downtime, we can empower operators to focus their efforts on clean energy generation.”
With offshore turbines designed to last for 20 to 25 years, solutions like Baltoflake have the potential to extend the life of new and existing turbines by more than ten years.
