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 the first year (FY94), A neural networks model has been developed to evaluate the significant wave height, period and direction basing on ship motions. In the second year (FY95), a wireless ship motions measurement sub-system has been developed. The success of this sub-system makes it feasible to install these sub-systems on the fleet of Taiwan Coast Guard and become a key technology of hardware in this research project. In the last year (FY96), a neural networks model has been developed to evaluate the overall wave field of the sea area around Taiwan basing on the limited numbers of wave data evaluated using measured ship motions of the fleet of Taiwan Coast Guard. In this year (FY97), research will be focused on the planning and simulation of a prototype system that can be used to evaluate the overall wave field of the sea area around Taiwan basing on the limited numbers of measured ship motions of the fleet of Taiwan Coast Guard.船舶運動波浪場臺灣海域Ship MotionsWave FieldTaiwan Sea Area
