Sizing Optimization Using Genetic Algorithm to Achieve Minimal Offshore Structure

Accelerating marginal field development must consider the economic factor. While structural strength remain capable and robust when subjected to environmental loads. To meet desired objective in design phase, optimization is used. With rapid growth of computing technology, method developed as more advanced reduced iteration time. However, evaluation jacket structure a complex problem. The usual process through finite element analysis, it still time-consuming. Thus, surrogate models can evaluate structure, lowering computational This study optimizes get an affordable minimal structure. Sizing will be performed on jacket's leg bracing thickness. For single-objective optimization, weight considered function, multi-objective adds production cost second function. model uses radial basis function predict relation between variables ultimate limit strength. functions generated from act behaviour constraints process. consideration, X-type V-type configurations are compared. Different results were obtained single
