APPARATUSES AND METHODS FOR MONITORING STRESS IN STEEL CATENARY RISERS
Apparatuses and methods of monitoring stress on steel catenary risers (SCR) are described, wherein a multi-strand optical cable extending down the length of the riser is provided and a plurality of optical fiber strain sensors are installed on the outer surface of the riser, said sensors being connected to the optical cable. The sensors may be pre-installed on new risers or post-installed on existing risers using remotely operated vehicles.
