Description This paper details the results obtained from static analysis, considering both operational and ultimate limit state performance characteristics of a jacket platform, designed at Mumbai high basin. The existing platforms at Mumbai high region are affected by continuous sea state and operational state loading. So, it becomes a necessity that the structures design for the purposes should be a reliable one. The Static load analysis done in this study, using the STRUCAD *3D software helps to analyze and predict the performance of a typical jacket structure at Mumbai High, when subjected to various load cases. The pile analysis performed using PILE 19.4 OASYS software gives the ultimate load carrying capacity, which the structure can withstand. The static analysis is also able to replicate the details of observed behavior of the designed structure. Based on the axial tension/compression and the bending stresses obtained through simulation, the tubular members are designed and the code unity check is done manually for two offshore standards i.e. ISO 19902[8], API RP 2A [1], on which the code provision comparison is performed to find more reliable code standards suiting the state of loading. The basic design of deck portion of the structure is also performed so as to obtain the preliminary design factors and member dimensions with respect to sea-state loading, thus the selection of dimensions based on existing jacket platforms in the considered location is also being discussed. The design load level is utilized to design structural elements, while the operational load level is applied to evaluate the capacity of the structure.
