The structure design of extending the water depth of the self platform

Aiming at the pressing issues of shorting in the drilling equipment when exploitation in deep water in the South China Sea, in the paper, a new model of upgrade about self-drilling platform was present. According to the prototype of existing self platform, a new type of underwater support structures was designed with bucket foundation that could be moved and reused, which led to economy and structural advantages. Finite element method was being used in this thesis to finish the Structural Analysis to assure its strength, while Performance Analysis of the overall model was carried out to assure its stability, to meet requirements to extending the water depth of the self platform, which was of great significance to the exploitation of ocean oil in the South China Sea.
