Lightweight design method of ocean jacket platform

Abstract

The invention relates to an ocean jacket platform, in particular to a lightweight design method of the ocean jacket platform. The method comprises the following steps: carrying out initialization modeling on an ocean jacket platform, and determining an initial design domain; analyzing the environmental load borne by the marine jacket platform; applying boundary conditions to the ocean jacket platform model, wherein the boundary conditions comprise fixed constraints and environmental loads; determining an optimization target, and constraining the volume of the model by taking the maximum rigidity of the marine jacket as the target; carrying out topological optimization on the ocean jacket platform through topological optimization software; performing shape and size optimization on the modelobtained through topological optimization; analyzing the marine jacket platform before and after optimization by using finite element software, and performing static and dynamic performance comparison; and if the requirements are met, outputting a final optimization model. According to the model optimized through the method, on the premise that certain weight is reduced, stress and displacement are reduced to a certain degree, and stress distribution of the whole structure is more uniform.

Description

technical field [0001] The invention relates to an ocean jacket platform, in particular to a lightweight design method for an ocean jacket platform. Background technique [0002] With the introduction of the green economy and the vigorous development of new offshore energy sources in recent years, new requirements have been put forward for the design of jacket platforms: improving structural performance and reducing manufacturing costs. For the design and manufacture of traditional offshore platforms, in order to ensure the normal progress of resource mining and the safety of staff, the platform is often designed conservatively, bulky and heavy, and the overall force is uneven; correspondingly, the cost of production and installation is high. In the past, the optimization of the platform structure was often based on the original platform, with limited modifications to the size and position of the jacket group, and the optimization effect was not particularly obvious.
