Abstract

In order to grasp the in-situ performance and structural characteristics of torch-type leg and cylindrical leg of jack-up platform, the applicable operating water depth ranges of the two legs are obtained. Based on the strength and hydrodynamic calculation theory, taking 375 ft jack-up platform as an example, the in-situ performance and structural and technological characteristics of the two legs are compared and analyzed. The results show that when the water depth is more than 60 m, the platform with torch leg has better environmental resistance and in-situ stability; when the water depth is less than 50 m, the performance of cylindrical leg platform and torch leg platform is similar, but the economic advantage of cylindrical leg is obvious, and it is more suitable for the sea area with smaller water depth. When the water depth is between 50 m and 60 m, the comprehensive performance of torch leg and cylindrical leg is comparable, and the specific selection form can be selected according to the design needs. The conclusions of this paper can guide the selection of pile legs of jack-up platform, and have certain guiding significance for the selection of Engineering design.
