INTEGRITY MONITORING OF CONDUITS |
摘要 |
The present invention relates to a method of integrity monitoring of a conduit. An optic fibre is provided optic fibre along the path of the conduit, and a fluid in the conduit is pressurized and depressurized. The optic fibre is interrogated to provide a distributed acoustic sensor, and data is sampled from a plurality of longitudinal portions of the fibre during the pressurizing and depressurizing. The data is processed to detect a signal characteristic of the integrity of the conduit. |
