A METHOD AND APPARATUS FOR A STRUCTURAL MONITORING DEVICE ADAPTED TO BE LOCATABLE WITHIN A TUBULAR STRUCTURE

摘要

A structural monitoring device adapted to be locatable within a tubular structure, the monitoring device comprises a plurality of supporting arms for supporting a plurality of fibre optic strain sensors; whereby each said supporting arm is arranged to support each said fibre optic strain sensor adjacent to an inner surface of the circumference of a monitored tubular structure to provide information indicative of strain sensed along a first axis and information indicative of strain sensed along a second axis.
