Fibre Optic Strain Sensors

Although the optical sensing technology has been available for a number of years the recent rapid adoption is due to a breakthrough in the way that optical fibre sensors are deployed. Optical fibres are now being embedded within a glass fibre/epoxy composite carrier to form a robust component suitable for handling offshore. The carrier provides resistance to damage during deployment and from extreme hydrostatic pressure. The installation processes becomes a simple matter of strapping the carrier to the structure to be monitored. To date such instrumentation devices have been deployed on deck, by rope access teams and by divers. ROV deployments are currently planned.
