Abstract

This paper presents preliminary results of a new guided wave system for detecting flooding in the hollow crossbeam members of offshore steel oil-rigs. A sensor, permanently attached to a sub-sea structure and powered by seawater, transmits chirp-encoded signals to a monitoring real-time digital signal processing system at surface level. Experiments performed using a jointed steel pipe structure, 10m×0.5m ×16mm, completely immersed in seawater showed that although attenuation was significant, the system successfully identified the signals.
