Abstract

The purpose of this study is to establish a design method of tower service lift for offshore wind power system, as well as to conduct structure analysis of the service lift system. The service lift system will be built in the internal area of tower of the offshore wind power system. Design and structure analysis for the tower service lift system are conducted to clarify the stability and reliability of the system. Main objective of the design is to secure sufficient capability of transportation of workers and equipment with satisfactory performance within the designed tolerance limit. Total deformation and equivalent stress of the lift system by external load are examined using the results of structure analysis.

본 연구 결과는 해상풍력발전시스템 타워 내부에 설치하는 서비스리프트의 설계 및 구조해석에 대한 내용이며, 공학적 설계법 및 수치해석에 의한 구조해석을 통하여 서비스리프트의 안정성 및 신뢰성을 확인하였다. 설계의 주된 내용은 설계 허용한계 이내에서 만족스러운 성능으로 지상으로부터 타워상부의 해상풍력터빈 너셀까지 작업자와 수리보수용 장비를 안전하게 수송할 수 있는 충분한 능력을 확보하는 것이다. 구조해석을 통하여 서비스리프트 캐빈 및 안전장치의 총변형량과 등가응력에 대해서 검토하여 설계 시 적용한 안전율의 타당성을 검토하였다.
