The transportation of oil is done mainly by ship tankers. In the last decades a lot of maritime disasters with these crude oil tankers occurred (e.g. Erika, Prestige). Every accident led to extreme pollution with horrible consequences not only for the environment but also for the life of the inhabitants of the affected coasts. Although most of these accidents were produced from human errors, the material degradation of the ship hull, caused by corrosion, played an important role. Because the Acoustic Emission technique is already used to detect and discriminate the stage of corrosion a consortium started to investigate the potential of this technique for oil tankers. The aim of this project is to develop an on-line monitoring during transportation by permanent installation and discontinuous measurement during stops in harbours by spot testing. Since the start of the project a lot of lab tests as well as background measurements were done on different types of oil tankers up to a size of 35.000 DWT. The gathered data were evaluated with a frequency domain pattern recognition system and it was possible to distinguish the acoustic signals from corrosion against the acoustic background noise on the ship. Together with the on-coming developments of specific AE-equipment and the improvement of the data base this project will lead to an important breakthrough for the safety of shipping hazardous products like crude oil.
