In the frame of the research project CLEAN guidelines for in-water cleaning have been developed by the Environmental Department of Bremen and bremenports. Actually, applications for permits can be submitted to the authority. The guidelines, additional information and activities in social media can be found under the topic projects, CLEAN.

Marine Fouling as biofilms and as macrofouling is a threat for a multitude of technical devices in freshwater and a dominant problem in marine waters.

  • Biofilms and Macrofouling can enhance the weight and the friction resistance to such a degree that a ship cannot speed ahead
  • Fouling at intakes of open cooling systems may reduce the amount of sucked to such a degree that the plant has to be shut down
  • Nets in mariculture can be fouled and clogged effectively thus leading to asphyxation of of fish oyster or abalones
  • Sluices may be fouled by sponges or oysters leading to malfunction or destruction of the anticorrosive coatings

Since 1991 LimnoMar has been working on the development of effective antifouling systems causing no threat to humans and wildlife. Up to now, and as a general conclusion based on the long-term experience, no universal valid and effective solution will be at hand. Instead customer and unit adapted solutions are at hand and have carefully to be selected. LimnoMar offers along with the investigation of innovative systems consultancy for customers focussing the most advanced systems with own experience.

LimnoMar is active as consultant and coordinator in conception and development of Biofouling Management strategies. Since 2018 LimnoMar has passed his marine station at the island Norderney to the company Brill-Hygiene, where a variety of efficacy tests of fouling prevention systems can be conducted ( ).
