Abstract
In calculating the allowable wave heights of a moored ship in a port, the suggested values in “Manual for Influence Evaluation of Long-Period Waves in Ports” are generally adopted as the allowable ship motions for the six components of moored ship motions. However, in calculating the allowable wave heights for a mooring facility where sea conditions are severe and a general mooring method or cargo handling method is not adopted such as a remote island port on the ocean, it is necessary to set the allowable ship motions with reference to judgment criteria at on-site cargo handling works and also to consider ship motions as well as the tensions of mooring ropes. Therefore, for the ports of Nanboku-Daito Islands located in the east of the main island of Okinawa, we studied the calculation methods of the allowable wave heights of a ship moored to the mooring facilities directly affected by ocean waves by using a numerical simulation method of moored ships.
