Abstract

Using cathodic protection (CP) electric field for estimating the conditions of oil tank hydroinsulation<br>is considered. A SP-CP (self-potential - cathodic protection) technique is suggested to locate the places of<br>hydroinsulation breaches. A value of CP local electric current is introduced to characterize the degree of<br>corrosion risk of oil tank bottom. Laboratory physical modeling of the technique is discussed and practical<br>example of successful SP-CP technique application for classifying oil tanks into categories of corrosion risk<br>is delivered.
