Abstract

Offshore wind power can be an alternative for onshore wind power which suffers from not only civil complaints regarding to landscape damage and noise but also wind power siting due to lack of onshore site candidates. Compared to onshore wind power, offshore wind power is free from these problems considering that generally the sites are far enough from the coast. And more electricity is generated in offshore wind turbines due to abundant offshore wind resources. However high installation costs of offshore turbines could deteriorate the economical efficiency. The main cause of the high installation costs comes from a long-term lease of the heavy marine equipment and the consequential high rental cost. In this paper, the conceptual design of the support structure for offshore wind turbines will be suggested for the installation of them with less heavy marine equipment.

해상풍력발전은 경관 및 소음 등의 문제 및 풍황자원 고갈로 인한 사업부지 확보가 어려운 육상풍력발전의 대안으로 주목받고 있다. 해상풍력은 해상에 풍력터빈을 세우기 때문에 경관 훼손이나 소음으로 인한 민원발생이 적고 상대적으로 풍황자원이 풍부하기 때문에 발전생산성이 높다. 그러나 육상풍력에 비해 해상풍력은 설치비가 높아 경제성이 떨어뜨리는 요인으로 작용한다. 이러한 높은 설치비는 해상작업에 필요한 대형장비의 대여기간과 높은 대여료에서 기인하는데, 본 논문에서는 대형 해상장비의 사용을 최소화하여 설치할 수 있는 해상풍력 지지구조의 개념설계를 수행하였다.
