Abstract
Structural joint strain monitoring apparatuscomprises jacket meansin the form of first and second jacket elements, each having a primary jacket partand substantially perpendicular secondary jacket partwhich together define a compartment for receiving a joint, between two pipes, to be monitored. The jacket meansadditionally comprises two primary web elementsprovided between the primary and secondary jacket parts. Three fiber Bragg grating (FBG) strain sensorsand an FBG temperature sensorare provided within an optical fiber, bonded to the primary web elementsand each end of the second jacket elementrespectively, for measuring strain or temperature at their respective locations. The FBG sensorsare optically coupled, via optical fiber, to optical fiber sensor interrogation apparatus, operable to interrogate each FBG sensor.
