Abstract: With the rapid development of the offshore wind power industry, offshore converter platforms are facing the challenge of evolving towards larger and heavier sizes. This trend makes the installation process of converter platforms increasingly complex and difficult. Considering this, lightweight design has become an important issue in the design of offshore converter platforms. This paper aims to propose an optimized design method for the layout of equipment on offshore converter platforms based on multidisciplinary optimization. Firstly, a detailed model of electrical equipment is established, and a set of equipment interference algorithms is developed. Subsequently, a variety of artificial intelligence algorithms are comprehensively applied to optimize the equipment layout, with the aim of obtaining a layout scheme that not only meets technical requirements but also optimizes the use of space. The research results indicate that the proposed algorithms and mathematical models can effectively guide the equipment layout of converter stations, providing a new solution for the lightweight design of offshore converter platforms.
