  • the anti-fouling unit comprises at least one electric circuit including a light-emitting arrangement configured to emit anti-fouling light and a power-receiving arrangement configured to receive power to be used for powering the light-emitting arrangement from an external power-supplying arrangement located on or near the surface, and a
  • the invention relates to an assembly of an object and a plurality of anti-fouling units as mentioned arranged on a surface of the object.
  • the invention is in the field of anti-fouling of surfaces. Fouling of surfaces that are exposed to water, during at least a part of their lifetime, is a well-known phenomenon that causes substantial problems in many fields. For example, in the field of shipping, biofouling on the hull of ships is known to cause a severe increase in drag of the ships, and thus increased fuel consumption of the ships. In this respect, it is estimated that an increase of up to 40% in fuel consumption can be attributed to biofouling.
  • biofouling is the accumulation of microorganisms, plants, algae, small animals and the like on surfaces. According to some estimates, over 1,800 species comprising over 4,000 organisms are responsible for biofouling. Hence, biofouling is caused by a wide variety of organisms, and involves much more than an attachment of barnacles and seaweeds to surfaces. Biofouling is divided into micro fouling which includes biofilm formation and bacterial adhesion, and macro fouling which includes the attachment of larger organisms. Due to the distinct chemistry and biology that determine what prevents them from settling, organisms are also classified as being hard or soft.
  • Hard fouling organisms include calcareous organisms such as barnacles, encrusting bryozoans, mollusks, polychaetes and other tube worms, and zebra mussels.
  • Soft fouling organisms include non-calcareous organisms such as seaweed, hydroids, algae and biofilm "slime”. Together, these organisms form a fouling community.
  • Biofouling can cause machinery to stop working and water inlets to get clogged, to mention only two other negative consequences than the above-mentioned increase of drag of ships.
  • topic of anti-biofouling i.e. the process of removing and/or preventing biofouling, is well-known.
  • WO 2014/188347 A1 discloses a method of anti-fouling of a surface while said surface is at least partially submersed in a liquid environment, in particular an aqueous or oily environment.
  • the method involves providing an anti-fouling light and providing an optical medium in close proximity to such a protected surface, the optical medium having a substantially flat emission surface. At least part of the light is distributed through the optical medium in a direction substantially parallel to the protected surface, and the anti-fouling light is emitted from the emission surface of the optical medium, in a direction away from the protected surface.
  • the anti-fouling light may be ultraviolet light

  • the protected surface can be the hull of a ship, as mentioned earlier, but the method is equally applicable to other types of surface.
  • WO 2014/188347 A1 further discloses a lighting module that is suitable to be used for putting the above-mentioned method to practice.
  • the lighting module comprises at least one light source for generating anti-fouling light and an optical medium for distributing the anti-fouling light from the light source.
  • the at least one light source and/or the optical medium may be at least partially arranged in, on and/or near the protected surface so as to emit the anti-fouling light in a direction away from the protected surface.
  • the lighting module known from WO 2014/188347 A1 may be provided as a foil that is suitable for application to the protected surface.
  • the foil may be substantially size-limited in two orthogonal directions perpendicular to a thickness direction of the foil, so as to provide a tile-shaped anti-fouling unit; in another embodiment, the foil is substantially size-limited in only one direction perpendicular to the thickness direction of the foil, so as to provide an elongated strip of anti-fouling foil.
  • anti-fouling units can be of any suitable shape and size.
  • square units may be used and arranged in a regular pattern on a ship's hull for forming an anti-fouling light emitting device on the hull, wherein each unit may be dimensioned so as to cover about 1 m 2 of the hull.

  • the at least one electric circuit further includes a power-receiving arrangement configured to receive power from outside of the anti-fouling unit to be used for powering the light-emitting arrangement.
