본 연구에서는 전국 28개 무역항에서 사용하는 전력을 해상풍력발전을 이용해 대체하기 위한 방안을 구상하였다. 이를 위해 전국 무역항의 1년간 평균 전기 소요량을 조사하였으며, 항계내로 제한된 수역에서의 풍력자원 잠재량을 추정하였다. 풍력자원 잠재량은 한국에너지기술연구원에서 기 구축된 1㎞×1㎞의 고해상도 국가 바람지도를 활용하였으며, 각종 지리적인 영향을 고려하였다. 이 결과로부터 정부의 기술개발 로드맵 등을 참조하여 해상풍력발전 개발을 위한 개발 가능한 시나리오를 구성하였다. In this study, we investigate how to substitute offshore wind power energy for electricity of whole nation 28 trading ports. To perform the research, average electricity requirements a year of whole nation trading ports and wind resource potentials of limited area of trading port have to be examined. Wind resource potentials can be obtained from high-resolution national wind map(1㎞×1㎞) of Korea Institute of Energy Research and the various geographic effects are considered. As a result, possible scenario for offshore wind power is composed from wind resource potentials and the road map of government's technology development.

Since ports, harbors, and coastal structures are affected by waves in any way, waves have a great effect on determining the stability of coastal structures. Especially, regardless of ship's size, the efficiency of shipping and discharging depends on harbor tranquility. Therefore in this study, the wave action is a considered to be a major factor to design coastal structure. So experiments were performed with various models of quay wall by examining their hydraulic characteristics for reflection rates and wave run-up. The final purpose of this study is to design various domestic unique models of quay wall which have the function of wave dissipation to improve cargo handling efficiency. The reflection rates and ship motions of three degrees of freedom-3DOF(sway, heave, roll) are also calculated by boundary element method (BEM). Calculated reflection rates from the BEM are compared with the results from the hydraulic model experiment. Although the values of numerical analysis generally exceed the values of hydraulic experiment, they showed the similar trend.
