Cathodic protection monitoring

A method of monitoring cathodic protection of an item located underwater at a facility, the facility further including a processing means, comprises the steps of: providing a pair of first and second electrodes, the first electrode being electrically connected to the item and the second electrode being in contact with water proximate the item; measuring the potential between the first and second electrodes; producing an electrical signal indicative of the cathodic protection level; converting the signal into a communications format compatible with the processing means and passing it to the processing means; and transmitting the converted signal from the processing means to a surface location.
