Abstract

For offshore wind turbine design, reliable observations of significant wave height and wind speed are essential, and thus metocean buoy data that simultaneously measure these variables are required. However, most metocean buoys have relatively short observation periods, which limits the reliability of estimating extreme metocean conditions. In this study, an environmental contour–based joint distribution approach is adopted to compare and analyze the differences in extreme metocean conditions depending on the observation period.

해상풍력 터빈 설계를 위해서는 유의파고와 풍속에 대한 신뢰성 있는 관측이 필수적이며, 이를 위해 두 변수를 동시에 계측하는 해양 기상 부이 자료가 필요하다. 그러나 대부분의 해양 기상 부이는 관측기간이 상대적으로 짧아 극한 해양환경 조건을 신뢰성 있게 추정하는 데 한계가 있다. 본 연구에서는 환경등고선에 기반한 결합분포 접근법을 적용하여, 관측기간에 따라 극한 해양환경 조건의 변화를 비교·분석하였다.
