ABSTRACT
The effectiveness of cathodic protection systems were studied at the tidal- inter-tidal and splash zone areas, by laboratory simulation test. Different electrolyte conducting materials (ECMs) have been used in order to select the most suitable condition; for achieving the most important factor for applying cathodic protection, in the splash zone area. Different sizes of both bare and coated steel were tested in natural seawater. Fully submersed and above water potential (splash zone) measurements, were been performed, on all executed experiments. The obtained results revealed that cathodic protection was achieved, on both bare & coated steel at above water (splash zone). The obtained results were confirmed, by both ultrasonic and visual observation, after long term test exposure. Optical photographic images, before and after exposing test samples, are presented. Structure to sea water potential versus exposure time as well as versus splash zone up ward distances, were recorded and presented. The simulation tests have been repeated in different environmental conditions, and reproducible results have been obtained.
