| Summary: | <p align="justify">Along with the enhancement of technology for oil and gas exploration, the fixed platform technology has also improved rapidly. This type of offshore platform needs to be designed precisely to support all of the activities at the structure without being disturbed. Planning and designing the offshore structure refers to API RP2A standard. In this study, Working Stress Design (WSD) is being used as a principles design. In the process of designing the offshore platform there are several structural analyzes that need to be done. The aim of those analyses is to find out the serviceability of the structure due to the working load. Those analyzes are in-place analysis, seismic and fatigue. The results of in-place analysis are unity check of member, unity check of joint punching shear, pile's capacity, and deflection due to loading that is occur on the structure when the structure is placed in the location. The results of seismic analysis are natural period of the structure, unity check of member, unity check of joint punching shear, and pile's capacity due to earthquake loads that is occur in the structure. The result of fatigue analysis is the service life of the structure due to cyclic wave loading. The results of structural analysis that has been done in this study show the braced monopod structure that has been designed already meet API RP2A - WSD design standards. The structure will proceed to the pre-service analysis stage. One of the analyzes that can be done is lifting analysis. The results of lifting analysis are the form of lifting configuration for braced monopod, the location of hook crane point, sling rope property, shackle property and dimension of padeye that have fulfilled API RP2A - WSD design standard.<p align="justify"> |
