ABSTRACT:
The invention describes apparatuses and methods of monitoring fatigue, structural response, and operational limits in structural components. More particularly, the present invention relates to fatigue, response, and operational monitoring systems on steel catenary risers using optical fiber sensors. The sensors can be pre-installed on new risers, or post-installed sub-sea on existing risers, using a variety of methods.
