摘要：There is natural correlation between the anti-corrosion state and the associated electric field (the ambient electric field) in Anti-corrosion system which combined coating protection with sacrificial anode. Based on analysis of the accurate mapping Relation between the anticorrosion state and the ambient electric field, a method of quantitative evaluation of anti-corrosion state of submarine pipeline by measuring the ambient electric field is proposed. Through Artificial Neural Network (ANN) learning, the mapping Relation between characteristic parameters of the ambient electric field and the parameters which describe the anti-corrosion state of submarine pipeline is gotten. It is concluded that this method comes true. And then, the solution for the non-contacting detection and quantitative evaluation of the anticorrosion state of submarine pipeline is proposed. ? 2010 by The International Society of Offshore and Polar Engineers (ISOPE).
