| Summary: | To be able to utilize the mineral in the Indonesian, it needs supporting in the infrastructure facilities for the exploration and exploitation of the oil and gas. One of the supporting infra-structure for this activity is the jacket offshore platform. Offshore platform structures need to be designed. In this research, the design and analysis of four legs jacket platforms located in the Natuna Sea.. In this research, the standard used is API Recommended Practice 2A - WSD for three analysis criteria, including in-place, seismic, fatigue analysis. Then modelling structure is using SACS 5.6. The structure fulfills the analysis after passing the member check stress check, joint punching shear, pile capacity and joint deflection checking. Fatigue analysis is performed by deterministic methods. The next analysis is the lifting analysis topside structure conducted to determine the strength of the structure during the lifting process and the lifting configuration, design and selection of lifting equipment and padeye design to be used.
