Prototype of biofouling-resistant optical instrument

The project resulted into a marine fouling prevention method feasible for implementation into optical oceanographic instruments for operational monitoring of oceans and coastal seas.

Buoy systems for marine environmental monitoring suffer from biofouling. Biofouling reduces the quality of the measurements, reduces the time between maintenance visits by boat and reduces the life time of instruments. Reduction or prevention of biofouling improves measurements and reduce operational and capital costs with 25 to 50%. Two biofouling prevention methods (hydrogel coating and local chlorination)have been tested under realistic conditions with optical instruments (transmissometers).

The local chlorination method proved to be effective and operational feasible. Implementation of the method and redesign of the instruments is being studied. Technical and financial issues will assessed before a final decission on redesign of the instrumentwill be taken. In case of a possitive outcome marketing of the redesigned instrument is expected within one year after the end of the project.
