Abstract: Offshore oil and gas platforms are critical infrastructures for the extraction of hydrocarbons from the sea bed. The design of these platforms is complex and requires multidisciplinary approaches which include following standards such as the API standards. The aim of this study was to design and analyze an offshore platform structure that could be used in the Gulf of Guinea Basin to extract oil and gas from the sub sea bed. In order to design a safe and reliable structure, factors such as the functions and location parameters were taken into account. With these factors loading conditions for the weight of equipment, water depth, currents and wind were designed and used in analyzing the structure. Firstly those parameters permitted to select the platform type which was the fixed offshore jacket platform due to its stability in shallow water regions and according to the API RP 2A WSD standard. Secondly a conceptual model for the offshore platform was designed in SACS software by selecting the appropriate material which was A36 steel mainly due to its weldablity. Solidworks were used to design the cellar deck layout. Finally the structure was optimized by performing stress and deflection analysis. The maximum deflection and unity check ratio were found to be 8.6cm and 1.0 respectively. These values were both cause by a bending stress of 5.77kg/mm2 acting in the local y-axis of the structure. In accordance to the API standards a comprehensive platform design was generated to withstand the environmental conditions of Gulf of Guinea Basin.
