| Abstract: | Ship motions on the small fishing boats for scallop cultivation in Funka-Bay, Hokkaido, are usually influenced by the dynamic force of large scale cultivation facilities. On the rough sea condition, it would generate fatal ship motions like large amplitude rolling motion. To reduce such ship motions under fishing conditions, we designed a new type of mooring device with buffer materials used as absorber for ship motions. We carried out the tank experiment used the model in the wave conditions corresponded to the actual fishing operation to confirm the effect of reducing ship motion. For the waves in the long-period frequently generated under rough sea, the damping effect of the absorber was effective to reduce rolling motion, and accounting for nothing less than 10.0% compared with the normal mooring device without the absorber. As a result, the mooring device with absorber is effective for the improvement of seakeeping qualities of the fishing boats for scallop cultivation. |
