JACKET STRUCTURE
To provide an economical jacket structure while securing sufficient performance with respect to both fatigue strength and ultimate strength.SOLUTION: A jacket structure 100 includes: a transition piece 10 for supporting an offshore wind turbine; a first steel pipe leg 21 for supporting the transition piece 10; a second steel pipe leg 22 for supporting the transition piece 10; and an oblique brace 30 for connecting the first steel pipe leg 21 and the second steel pipe leg 22. Out of an upper stage part U which is a portion of the first steel pipe leg 21 and which includes an intersection of the first steel pipe leg 21 and an upper end of the oblique brace 30, and a lower stage portion L which is a portion of the second steel pipe leg 22 and which includes an intersection of the second steel pipe leg 22 and a lower end of the oblique brace 30, regarding the one in which a fatigue load is dominant, a first steel material is used, and regarding the one in which an ultimate load is dominant, a second steel material which has higher strength than the first steel material is used.SELECTED DRAWING: Figure 1
【課題】疲労強度及び終局強度の両方に対して十分な性能を担保しつつ、経済的なジャケット構造体を提供する。【解決手段】洋上風車を支持するトランジションピース１０と、トランジションピース１０を支持する第１の鋼管レグ２１と、トランジションピース１０を支持する第２の鋼管レグ２２と、第１の鋼管レグ２１と第２の鋼管レグ２２とを接続する斜めブレース３０と、を備えるジャケット構造体１００であって、第１の鋼管レグ２１の部分であって、第１の鋼管レグ２１と斜めブレース３０の上端との交点を含む上段部分Ｕと、第２の鋼管レグ２２の部分であって、第２の鋼管レグ２２と斜めブレース３０の下端との交点を含む下段部分Ｌと、のうち、疲労荷重が支配的であるものについては、第１鋼材が使用され、終局荷重が支配的であるものについては、第１鋼材より高強度な第２鋼材が使用される、ことを特徴とする。【選択図】図１
