The design of offshore fixed platform structures is a crucial aspect of the offshore oil and gas industry, particularly in ensuring safety, reliability, and operational efficiency. This study aims to optimize the structural strength of offshore fixed platforms through in-place and fatigue analysis. In-place analysis is conducted to evaluate the structure's ability to withstand environmental loads such as waves, currents, and wind, as well as other operational loads. Meanwhile, fatigue analysis is used to assess the service life of the structure due to long-term cyclic loading. The research methodology includes numerical modeling using finite element-based software to simulate the structural response under various loading conditions. The results of the in-place analysis provide an overview of the stress distribution and deformation occurring in the structure, while the fatigue analysis identifies critical points that are vulnerable to failure due to material fatigue. By understanding these two aspects, this study provides optimal design recommendations to enhance the structural resilience against dynamic loads and extend its service life. The results of this research are expected to contribute to the development of more efficient, safe, and sustainable offshore fixed platform designs while reducing the risk of structural failure that could impact economic and environmental aspects.
