Continuous structural health monitoring guided wave PPM system using steel pipes as communication channel for flood detection in steel offshore oilrigs

Research output: Contribution to journalArticlepeer-review

Abstract

An automatic guided wave pulse position modulation system, using steel tubes as communication channel, for detecting flooding in the hollow sub-sea structures of offshore oilrigs is presented. The system employs two smart PZT-based sensors and modulators and a demodulator based on a PZT transducer, a DSP and a microcontroller. Experiments performed in a tubular steel heliport structure and the base of a deck of an oilrig under construction, have successfully distinguished automatically guided wave encoded information.
