New coat keeps DFDS on green course

Danish ship owner DFDS has selected the hard coating Ecospeed from Subsea Industries as a means of realising its ecological targets.

Last July the underwater hull of the roro vessel Magnolia Seaways was coated with Ecospeed in Gdansk, Poland and at the same time the rudder of the ship was treated with Ecoshield coating which was designed specifically to protect underwater gear against cavitation and corrosion damage. The 200m vessel is currently sailing a fixed Ghent-Gothenburg-Immingham route.

DFDS takes its environmental responsibility very seriously and as well as being in a partnership with marine whale and dolphin conservation charity ORCA, the company is committed to reducing its energy consumption and impact on the environment by improving its operations and activities on an ongoing basis focused on reducing emissions from ships, as well as on developing and implementing new environmental technology for use at sea.

Subsea Industries says that Ecospeed ties in perfectly with the ecological ideas of DFDS. The coating offers a TBT-free, copper-free, biocide-free and silicone oil free solution for the protection of the underwater hull. Stringent independent tests carried out in the Netherlands and in Canada proved that the coatings are 100% non-toxic and that there is no negative effect on the water quality or the marine environment at any point of their use. The emission of massive amounts of VOC and zinc anodes associated with conventional coating systems is reduced to almost zero.


Another important outcome of the independent tests was the submission of the results to port authorities and environmental agencies worldwide in order to allow the underwater treatment of the coating systems. As a result several economically important ports have made an exception to the ban and this only for Subsea Industries’ coatings. Underwater hull maintenance is carried out with specially designed underwater hull cleaning tools that simultaneously clean and optimise the smoothness of coatings. This can be repeated whenever needed during the vessel’s lifespan without causing damage to the coating’s surface.
