The invention relates to the technical field of offshore wind power, and discloses a novel transition section structure of an offshore wind turbine jacket foundation and a fatigue calculation method, the structure comprises a top plate, a bottom plate, and a web plate, a reinforcing toggle plate, a supporting plate, a main leg, an inner ring plate and a samson post which are arranged between the top plate and the bottom plate. The web plate reinforced structure is adopted, the novel transition section structure of the large megawatt fan is designed and optimized, compared with a traditional box girder type transition section, the construction cost is greatly reduced, the transition section structure can provide good bearing capacity for transmitted fan loads, and the service life of the large megawatt fan is prolonged. The method can effectively reduce accumulated fatigue damage caused by large megawatt fan load, further can accurately calculate the accumulated fatigue damage of the transition section structu
