Abstract
A strategy to increase the production of oil and gas is through acceleration the development of marginal fields. Economic factors largely determine the marginal field. Currently, regarding structural design, there are still many results of offshore structures that are overdesigned at a certain level. Thus, structural optimization is important in the design phase. It leads to production cost minimization. Therefore, this study analyses the optimization of a jacket structure to get an economical and reliable minimum jacket structure. Dimension optimization will be carried out on the main structure of the jacket and the objective function in the form of minimizing material costs. Surrogate model is used to evaluate the structure. It is constructed by radial basis function. The optimization process uses the the non linear programming. This research is expected to recommend a minimum jacket structure optimization model approach that can be used especially for Indonesian waters.
