ABSTRACT:
A method for detecting the ingress of liquid into an empty elongate hollow structure such as a support for an offshore platform which is at least in part submerged in a liquid. Sound is introduced into the structure by a sound generating device mounted within the hollow structure, the device comprising sound generating means and liquid detection means. When the liquid detection means detect an ingress of liquid into the structure, the sound generating means generate a sound in response to this detection. The generated sound propagates through the structure and sound is detected, and detection of the sound giving an indication of liquid ingress into the structure.
