Floating Production Storage and Offloading (FPSO) platforms play a crucial role in offshore oil and gas production, providing flexibility and the ability to operate in deep waters. This study delves into the design, operation, and environmental considerations of FPSO topside modules. It begins with detailed modeling, incorporating assessments of various loads such as Dead, Live, and Wind loads. The study evaluates the platform's stability under both normal and extreme conditions through Inplace Analysis. Additionally, it examines the FPSO's behavior during deployment and relocation using Lifting analysis. By assessing these factors, the study offers comprehensive insights into the structural integrity, operational efficiency, and environmental impact of FPSO platforms. These findings are instrumental in optimizing the design, functionality, and deployment of FPSO platforms, ensuring they meet safety standards and maximize resource utilization. The study contributes significantly to advancing knowledge in the field, providing a foundation for future improvements in FPSO technology and operations.
Engineered constructions, known as offshore structures, are made to function in maritime conditions, usually in the open sea or coastal regions. These structures are essential to many different industries, including telecommunications, marine transportation, offshore wind farms, oil and gas exploration, and renewable energy production. Oil and gas are the most extensively used energy sources because of their low cost and improvements in drilling and development. Because fixed production platforms are expensive in deep ocean regions, floating production platforms are a more cost-effective solution (Sharma et al., 2013). Structural dynamics is the behavior of structures subjected to dynamic activities with high acceleration loading (Sharma et al., 2013). The offshore structure is subjected to various environmental pressures, including wind, waves, and currents, during the operation. The right wave theory, such as Stokes theory or linear wave theory, is needed to ascertain the water particle kinematics in order to apply Morison's equation for calculating the wave load (Vendhan, 2013). Under the ocean floor, these structures are used for exploration and the extraction of natural gas and oil. Among other forms, they can be found on subsea systems, floating platforms, and fixed platforms. Fixed platforms are fastened to the seabed, whilst floating platforms are held in place by buoyant structures. The design and analysis of these structures are critical and can be done in software like SACS. SACS is a software program used for structural analysis and design in the offshore and maritime sectors. It facilitates engineers’ and architects’ modeling and analysis of the behavior of offshore installations such as bridges and oil platforms. SACS can perform different types of analysis like static structural, dynamic, fatigue, seismic, pile/soil interaction, nonlinear, progressive collapse, buckling, wave load, environmental load, in-place, and transportation and installation analysis.
