Stability and Hydrodynamic Analysis of a Deepwater Spar Platformin The Gulf of Mexico

Abstract

Global energy demand has driven the oil industry to develop floating systems with stability, low response motions, high production capacity for oil and gas in deep and ultra-deep water. Its development is an iterative process, due to the fact that it analyzes the production and safety requirements according to the bases of the project, and subsequently it will advance or go back, according to its performance, one step in the design spiral. Hernandez-Menez (2020) states that it is a meticulous process, given the high cost it represents, it requires an excellent and functional design, according to the specifications required for a safe operation. For this reason, new floating systems have been developed, such as Spar-type platforms. Hernandez-Hernandez (2020) mentions that the environmental conditions, hull shapes and weight distribution are key factors for the stability and hydrodynamic response of a floating production system which is why stability and minimal motion are sought to prevent a stoppage or failure in oil and gas production equipment. Currently there is not a floating system of this type in Mexican territory, this study analyzes a case under environmental conditions of the Gulf of Mexico, establishing the hull shape, stability criteria and loading conditions to determine the motions of the platform
