The present invention relates to a crane for installing an offshore wind turbine. The offshore wind turbine, which is longer than the height of a crane, can be installed vertically and installed on the sea to drastically reduce crane installation costs and installation time. In addition, the offshore wind turbine can be safely and freely moved in a vertically erected position to a desired location by using the crane for installing the offshore wind turbine. Even when an assembled offshore wind turbine is erected vertically, the center of gravity is prevented from being disturbed and overturned by a blade and nacelle load. Thus, the present invention is beneficial for securing work stability. The crane for installing the offshore wind turbine consists of first and second crane modules provided on both sides of a front half of a hull of an installation ship for installing the offshore wind turbine, and third and fourth crane modules provided on both sides of a rear half of the hull.

    본 발명은 해상 풍력발전기 설치용 크레인에 관한 것으로, 크레인의 높이보다 길이가 긴 해상 풍력발전기를 수직으로 세워 해상에 설치할 수 있어 크레인 설치 비용과 설치시간을 대폭 절감할 수 있을 뿐만 아니라 해상 풍력발전기 설치용 크레인을 이용해 수직으로 세운 상태의 해상 풍력발전기를 원하는 위치로 안전하면서도 자유롭게 이동시킬 수 있을 뿐만 아니라 조립된 상태의 해상 풍력발전기를 수직으로 세우는 경우에도 블레이드와 너셀 하중에 의해 무게중심이 흐트러지며 뒤집히는 것도 방지할 수 있어 작업 안정성 확보에도 유리한 해상 풍력발전기 설치용 크레인을 제공한다.
