This paper analyzes serviceability guidelines and index related to the motion of floating structures concerning human comfort. The guidelines for the motion of floating structures regarding human comfort must meet requirements such as including frequency range of floating structure and providing index for vertical direction, which is a major component of human discomfort. Therefore, ISO 2631-1:1997 was found to be applicable. The evaluation of serviceability of the floating structure showed that the frequency-weighted RMS acceleration, due to the characteristics of frequency weighting function, is significantly influenced by the period of the floating structure. Additionally, the frequency-weighted RMS acceleration presented lower values compared to the general RMS acceleration. These results are expected to contribute to the establishment of reasonable guidelines for human activities to the motion of floating structures. |
