“…Chen et al [ 122 ] extracted data from the full-scale measurements of a 14,000 TEU double bottom container ship, whose sea states are similar to those of numerical simulation among the existing time series, in order to analyze the correlation between the double bottom and hull girder bending, on wave and vibrational response. Miyashita et al [ 123 ] presented full-scale calculations (longitudinal stresses) of an 8600 TEU container ship carried out during four years and two months.…”

This paper presents a comprehensive review of the state-of-the-art developments in health monitoring of marine structures. Monitoring the health of marine structures plays a key role in reducing the risk of structural failure. The authors establish the different sensors with their theoretical foundations and applications in order to determine the optimal position of the sensors on board. Once the data were collected, it was necessary to use for subsequent treatment; thus, the authors identified the different methodologies related to the treatment of data collected by the sensors. The authors provide a historical review of the location of different sensors depending on the type of ship and offshore platform. Finally, this review paper states the conclusions and future trends of this technology.

This paper presents a method for estimating the sectional loads along ship hull girder in real-time by combining a Kalman filtering algorithm and a mode superposition method, as part of digital twining system. The developed method is applied to a full-scale measurement on an 8600 TEU container ship and the strain signal at several locations is used as inputs to estimate hull deformation and external loads. The stress distribution at deck level due to vertical bending moment, and horizontal and torsional moment distributions are presented and discussed. Then, the method is extended for identifying whipping and springing events. It is justified by comparing with other methods that have been accepted so far. The effects of whipping and springing on fatigue damage are respectively analyzed by separating the wave-induced vibrations into whipping and springing. It is shown that the fatigue damage caused by the wave-induced vibrations is significant and the fatigue damage caused by springing is equivalent to, or even larger than the one by whipping.
