Don’t forget to consider tide levels when monitoring cathodic protection levels on steel structures, especially if the impressed current anodes are not submerged at low tide.
Generally, if the anodes are not submerged they cannot provide effective cathodic protection to the adjacent structure. Consequently, anode current is usually optimised whilst the anode (and structure to be protected) is fully submerged. It is also important to note that the anodes are more likely to be protected from mechanical damage (eg. vessel hulls, thruster wash) whilst submerged.
