ABSTRACT
This study conducts a comprehensive numerical analysis for design and optimization of a conceptual subsea vertical separator for deep-water applications. Following functional requirements and available industrial practice, a case study of a vertical subsea-separator has been conceptualized. A methodology is suggested in the paper for its adequate design. Finite element analyses are conducted using a full scale model to identify important design parameters, followed by a parametric study. Comparisons of the buckling strength estimated from relevant analytical models are also presented. A scheme of iterative analyses is further conducted to optimize the design based on finite element analysis. The results of this study may be useful for the subsea technology developers.
