The FPSO vessel is prone to corrosion and corrosion-induced structural degradation because of the saline marine environment and continuous loading/offloading operation. To assure the structural integrity and safe operation, they must be inspected periodically, and ideally continuously monitored. 16 types of sensing technologies were identified for monitoring of FPSO Vessel. Depending on the technology matureness and readiness for application in marine structures, they were categorized into three groups: Proven, Un-Proven and State-of-the-art technology. Challenges associated with FPSO hull monitoring including Sensor Systems, Communication and Data Analysis were examined. It is concluded that multiple sensing technologies should be systematically combined to provide more accurate information. MEMS sensors were identified to be especially useful for hotspots monitoring due to their small footprints and low cost. A feasible solution that integrates proper wireless sensor network technology and Bayesian Network modeling was proposed as the future direction of FPSO hull monitoring system.
