“Now, though, the unique combination of our patented Lubyon polymer technology, the self-polishing copolymer silyl methacrylate, and biocide components copper oxide and copper pyrithione are producing spectacular results for various ship types trading in regions with different fouling risks. Applications so far in the cruise sector are proving very successful. We are confident that Intercept 8500 LPP will not disappoint our cruise customers!” Mangano adds.
Predictable performance is particularly important for cruise operators whose ships operate on schedules which are accurate to within a few minutes. Depending on a ship’s operating profile, cruise operators may choose shorter or longer drydocking schedules, but Intercept 8500 LPP can be tailored to meet ship-specific requirements whilst still maintaining the same linear polishing rate.
However, Mangano draws attention to other benefits too. He explains that the coating offers outstanding performance for ships with relatively low activity in high-risk fouling areas. In the Caribbean, for example, cruise ships may hop from island to island, on relatively short voyages and with lengthy periods at anchor or on berth. The coating’s antifouling properties work equally well whether a cruise vessel is stationary or under way.
Then there is the nature of the coating itself. Intercept 8500 LPP is extremely smooth and in some of the first applications has shown surface roughness measurements of 46 microns, 67 microns and 89 microns as compared with other products sold in this sector which are in the 90-100 microns range. Since hull roughness is a direct determinant of a ship’s skin friction resistance, Mangano points out, it is clear that a smoother hull is a benefit.
In fact, in an internal experiment, AkzoNobel’s analysts discovered that Intercept 8500 LPP, applied to a cruise ship’s hull in waters with a high fouling risk, required 2% less power than the company’s other antifouling – Intersmooth 7460HS SPC. Mangano reveals that in a cost benefit analysis based on bunker fuel at $350/tonne, applying Intercept 8500 LPP gave a payback time of 20 months and a reduction in carbon dioxide emissions of 10,000 tonnes over five years.
So far, AkzoNobel has notched up a series of successes in the maintenance and repair sector, with projects successfully completed for leading cruise lines including Princess Cruises on the Regal Princess and Costa Crociere for its Costa Luminosa and Costa Serena. In addition, Aida cruises has selected Intercept 8500 LPP on the Aida Vita.
“It’s only a matter of time until the cruise market fully realises the benefits of Intercept 8500 LPP,” Mangano declares.
