Zusammenfassung:	To provide a jacket structure for an offshore wind turbine and a welding method for a jacket structure for an offshore wind turbine that are capable of ensuring sufficient fatigue strength in a connection area.SOLUTION: A jacket structure 100 for offshore wind turbine comprises: a first diagonal brace 10, which is a cylindrical member; a second diagonal brace 20, which is a cylindrical member and intersects the first diagonal brace 10; and a platform 30 on which an offshore wind turbine 200 is mounted and which is supported by the first diagonal brace 10 and the second diagonal brace 20. The intersection of the first diagonal brace 10 and the second diagonal brace 20 is welded on both sides.SELECTED DRAWING: Figure 1 【課題】接続部に十分な疲労強度を確保することができる洋上風車用ジャケット構造物及び洋上風車用ジャケット構造物の溶接方法を提供する。【解決手段】円筒状の部材である第１斜めブレース１０と、円筒状の部材であり、且つ、第１斜めブレース１０と交わる第２斜めブレース２０と、洋上風車２００が設置され、且つ、第１斜めブレース１０及び第２斜めブレース２０に支持される台３０と、を備える洋上風車用ジャケット構造物１００であって、第１斜めブレース１０と第２斜めブレース２０との交点は、両面溶接されることを特徴とする。【選択図】図１
