| Popis: | Since the advent of hydroelasticity issues in the marine community, a full scale measurement campaign has been considered the most important research to reach a thorough understanding of this complicated physical phenomenon. This study examined the full-scale measurement data of a large container carrier with a 9400TEU capacity. First, modal parameters, such as the mode shapes, natural frequencies, and damping ratios, were examined based upon the measured acceleration data on deck. The evolution of the natural frequencies and damping ratios were also checked and their correlation was explored. In addition, the modal magnitude obtained using the acceleration data was cross-compared with the strain at deck to investigate their temporal relevance. Finally, the fatigue damage was calculated using the measured strain at deck and the expected long-term fatigue damage was estimated based upon the fatigue damage experienced by the vessel during the measurement period. |
