Stena RoRo are reaping the benefits from an antifouling coating with Selektope®

Stena RoRo has chosen Selektope® as a key technology for new vessels

One of the leading innovators in the roll on/roll off cargo and passenger vessel sector, Stena RoRo, selected Selektope® as a key technology for their new vessels. Flexibility and innovation are hallmarks of Stena RoRo. Building, converting and adapting vessels are in their DNA – and they call that “Stenability”.

The latest success in Stena RoRo’s quest for innovation, the E-Flexer series, encompasses nine passenger and vehicle ‘RoPax’ vessels. These vessels have an Energy Efficiency Design Index (EEDI) that is significantly better than their existing, older RoPax-peers and regardless of which fuel will be consumed onboard, it will be much less than other RoPax vessels on the water. The innovative configuration on the E-Flexer also contributes to a 25% reduction in CO2 emissions compared to current generation of RoRo vessels. To realise this enhancement in efficiency and reduction of emissions, Stena RoRo has cooperated with an array of well-known suppliers in the industry, including , Caterpillar, the CMI Jinling (Weihai) Shipyard in China, Deltamarin, Chugoku Marine Paints and I-Tech.

” We selected an anti-fouling paint with Selektope® inside as we are striving to achieve the highest fuel efficiency and the lowest emissions on these E-Flexer vessels, in order to fully utilize the efficiency designed into the propulsion system over time.”
Per Westling, CEO Stena RoRO

Stena Estrid was the first vessel in the series to be delivered in November 2019. Her hull is coated with the Selektope®-powered antifouling product SEAFLO NEO CF PREMIUM from Chugoku Marine Paints. Selektope® acts as the cornerstone in this coating’s design, which has a very low surface roughness and well proven capability to resist soft and hard fouling. With Selektope® inside, the coating not only has an unmatched ability to resist barnacle fouling even when exposed to longer static periods, but also it enables the use of other technologies to combat the constant issue of slime, seagrass and sea-weed fouling. In addition, the coating system has a significant reduction in biocidal leaching. Another major aspect, among the various efficiency measures taken by Stena RoRo for these vessels, is excellent hydrodynamic per-formance. The E-Flexer series has a hull shaped to reduce resistance through water, with a stern and propulsion system designed to reduce wave making and hence reduce the fuel consumption and emissions.
