Besides, the related key technologies will be also developed in this project of four years term.Firstly, in the 1st year (FY94), the method and computer program to evaluate wave field basing on ship motions will be developed, then in the 2nd year (FY95), wireless module for ship motions measurement will be developed, and the method and computer program to evaluate the overall wave field of the sea area around Taiwan basing on the ship motions data of a fleet will be developed in the 3rd year (FY96), finally, in the 4th year (FY97), the planning as well as simulation for the ship-bone wave monitoring system for the sea area around Taiwan by using the fleet of Taiwan Coast Guard will be followed.In this year (FY94), the procedure and method are as follows. A practical method for calculating the ship motions of a high-speed craft in oblique waves developed by the PI will be used firstly to obtain the transfer function of ship responses. Then, the ship motions in short crested irregular waves will be analyzed. And, a neural networks model will be developed and trained to become an available tool to evaluate the significant wave height, period and direction basing on ship motions. Finally, the validity of the model will be evaluated by simulation as well as available experimental data.船舶運動波浪台灣Ship MotionsWavesTaiwan
