多胴型海洋構造物の波浪中減衰力増加について

In order to investigate the damping increase of a moored multi-hull platform during low-frequency motions in waves, free oscillation tests were conducted both in still water and regular waves. It is found that the estimation method for the damping increase of a mono-hull platform gives a relatively good results for a multi-hull platform. For a more precise prediction, further study on the evaluation of the wave drift force of a multi-hull platform is needed.
