An in-line inspection tool for the detection of stress corrosion cracking (SCC) and coating disbondment based on electro-magnetic acoustic transducers was developed, following a high-resolution approach. After having successfully tested this 16’’ EMAT Crack Detection (ECD) tool thoroughly in sample pipes containing real SCCs and various types of artificial defects, first runs - one in a gas pipeline and another one in an oil pipeline - were performed that proved the performance of the approach under operational conditions. This article introduces some parts of the data evaluation process and presents first results obtained from these two field tests.
