Abstract: In this paper, the pile shoe jacket foundation of offshore substation is deeply studied. Through theoretical research and calculation analysis, a set of design methods that can be applied to practical engineering are formed. Compared with the traditional pile leg jacket foundation, the pile diameter of the shoe jacket foundation of offshore substation is not limited by the section of main leg of jacket and the pile length is controllable which reduces the construction risk. In conclusion, the shoe pile jacket foundation of offshore substation is applicable to a wider range of water depth and to the geological conditions with deep soft soil on the surface.
