Zusammenfassung:	To provide a jacket structure for an offshore wind turbine which can secure sufficient fatigue strength in a connection part, and to provide a welding method of the jacket structure for the offshore wind turbine.SOLUTION: A jacket structure 100 for an offshore wind turbine includes: a first oblique brace 40 which is a cylindrical member; a second oblique brace 50 which is a cylindrical member and intersects with the first oblique brace 40; and a pedestal 20 in which an offshore wind turbine 300 is installed and which is supported by the first oblique brace 40 and the second oblique brace 50. At an intersection between the first oblique brace 40 and the second oblique brace 50, double side welding is performed.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４０と、円筒状の部材であり、且つ、第１斜めブレース４０と交わる第２斜めブレース５０と、洋上風車３００が設置され、且つ、第１斜めブレース４０及び第２斜めブレース５０に支持される台２０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４０と第２斜めブレース５０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
