Abstract

In this study, geometric calculation was performed to investigate the influence of the combined effect of tilt and misorientation on the pullout capacity of suction anchor used in floating offshore wind turbine. When considering the combined effect of tilt and misorientation, it was observed that they do not proportionally affect the pullout capacity but rather influence each other relatively. Criteria considering both tilt and misorientation are not provided in existing literature or DNV recommendation. Therefore, based on the comprehensive results of this study, a proposed decrease in pullout capacity within 3% is suggested.

본 연구에서는 기하학적 방법을 통한 계산을 수행하여 석션앵커의 수직도와 회전오차의 복합작용이 인발지지력에 미치는 영향을 알아보았다. 수직도와 회전오차의 복합영향을 고려한 경우 단순 비례적으로 인발지지력에 영향을 미치지는 않고 서로 상대적으로 영향을 미치는 것으로 나타났다. 수직도와 회전오차를 복합적으로 고려한 기준은 기존문헌이나 DNV 기준에 제시되어 있지 않아 본 연구 결과를 종합하여 인발지지력의 감소폭 3%내를 제안하였다.
