On Optimal Method of Mooring Ship in Floating Tsunami Protection Wharf Available to Purchase

On the vessels moored the quay, the situation such as drifting and runs on the quay due to the breaking of the mooring lines is generated by the tsunami. The authors are clarified for applicability of the proposed floating tsunami protection wharf (FTPW) and install more mooring tether. The effect of FTPW is most promising as disaster prevention and mitigation measures for the vessels moored quay, but exert a sufficient effect in the transverse tsunami incident, but the effect cannot be confirmed in the longitudinal tsunami incident. Therefore, it is necessary to go in combination in FTPW and tsunami countermeasures in consideration of the longitudinal tsunami incident, such as install more mooring tether and new mooring method. The objectives of present study are to consider valid mooring method for longitudinal tsunami incident and also to propose a tsunami most effective countermeasure of wharf mooring vessel.
