This paper reports experimental results obtained with fibre  Bragg grating (FBG) optical hydrophones for the acoustic detection of water-leak signals. The methodology  combined in situ measurements in a tank with an actual leak, aimed at characterising the associated acoustic  signature, and controlled laboratory tests where several FBG prototypes were compared against a conventional  reference hydrophone. The results showed that the leak produced extremely low-amplitude signals, barely  distinguishable from the background noise, which represents a significant detection challenge. After the  preliminary evaluation of several FBG prototypes, the most balanced configuration was selected for subsequent  tests, although its sensitivity was considered insufficient for reliable detection of the real leak.
