Anti-Fouling Film RENOLIT DOLPHIN S Tested on Fairway Buoys

The buoy with the RENOLIT DOLPHIN S film was almost completely free of encrustation.. “I’m impressed,” says Jörg Böning from the WSA in Bremerhaven.

In April 2018, the German Waterways and Shipping Authority (WSA) in Bremerhaven decided to test this film solution from RENOLIT. “I found out about the film in an article and wondered if this wouldn’t be a good solution to the fouling of our fairway buoys. Sometimes these buoys get so heavily encrusted that they barely float above water and are thus hardly visible for passing vessels. For this reason, the buoys have to be checked and cleaned regularly,” says Jörg Böning from the WSA in Bremerhaven.

Three buoys were prepared for testing in April 2018. One, (No. 45) was painted as usual with a corrosion protection, the second, (No. 47) was given an additional paint coating and the third buoy (No. 48) was wrapped with RENOLIT DOLPHIN S. All three were anchored in the Weser estuary about 10 km from Bremerhaven within an area of about half a nautical mile so that they would be subject to similar fouling.

When the buoys were lifted out of the water on August 30, 2018, the wrapped buoy showed the best results. The two buoys with the corrosion protection paint and the additional paint coating were heavily fouled with barnacles, mussels and algae. The buoy with the RENOLIT DOLPHIN S film on the other hand, was almost completely free of encrustation.* “I’m impressed,” says Böning, “If further long-term practical trials are equally positive, we will be able to cut overall operating costs by reducing the frequency of inspection trips to the buoys”.

Protective Coating Film – Better performance and cost optimization

Films as surface protection in the maritime industry – with these innovations, the film specialist has entered a completely new area. RENOLIT is now making a strong impact in maritime applications. Regardless of whether anti-slip films, fouling release films or protection films for working vessels: RENOLIT’s solutions for the seas and inland waterways always offer the maximum customer benefit.

Wrapping Workboats: Clean, Fast and Economical

One of the arguments for these innovative films as an alternative or supplement to conventional paint coatings is the visual effect. Whereas paint coatings are often of varying thicknesses, the films are consistently thick. Moreover, they are easily applied and can effect small localized repairs. Additionally, the films offer reliable protection and durability for your working vessel. Another advantage is that during the application of the films no volatile organic compounds (VOC) evaporate. This means that no harmful substances are released and no special precautions need to be taken such as the wearing of protective clothing. Maintenance work (also welding) can be carried out at the same time as application and this also reduces downtime.

RENOLIT sells its film innovations for workboats and ships as well as for other maritime applications primarily to industrial customers. Smaller quantities for private use are available from our constantly growing network of sales partners.
