The oil transportation over the sea with oil tankers can become, because of oil spillage in case of an accident, very dangerous for the environment, with fatal consequences for Flora and Fauna, e.g. the accidents of Prestige and Erika. The accidents were often caused by the degradation of the structural integrity (corrosion). An EC-funded R&D project had the intention to develop discontinuous and permanent installed AE testing systems for the detection of corrosion attack on oil tankers in-time. After extensive research works about the corrosion process and its effect on the emitted Acoustic Emission, the technology was able to distinguish meaningful corrosion noise from disturb noise. After development of intrinsically safe (Ex-proof) sensors, both systems were tested for their validation on real ships (Navy and commercially used oil tankers). These tests proof, that the permanent systems is able to check during the most service conditions and the spot testing has the capability to check and validate to corrosion status of the structure in harbour or on anchor place.
