By summarizing and analyzing the relevant parameters of the offshore oil platform built in a construction site in recent years, the structure form of the boot-type support is optimized to make them universal. According to the structure form of the optimized boot-type support, the optimal layout scheme of the weighting system for the corresponding oil platform is given, and the strength of the optimized boot-type support can meet the construction requirements by calculating and checking through ANSYS software. The points for attention in the practical construction of the universal boot-type support are given.
