Embodiments of the present invention provide a unique new approach to generating operating condition information used for assessing flow assurance and structural integrity. More specifically, apparatuses, systems and sensor housing assemblies configured in accordance with embodiments of the present invention utilize fiber optic sensors for enabling monitoring of operating condition information within one or more elongated tubular members within a subsea environment. To this end, such fiber optic sensors connected by lengths of optical fiber are strategically placed at a plurality of locations along a length of each elongated tubular member thereby allowing critical operating conditions such as strain, temperature and pressure of the elongated tubular member and/or a fluid therein to be monitored. A viscous media is used for mitigating attenuation associated with exposure of optical fiber exposed to forces generated by pressure within the subsea environment.
