Abstract: To address the fault issue of equipment short circuits caused by the detachment of electrode components in electrostatic dehydrators for offshore oilfields,a scheme integrating structural optimization and process improvement is proposed based on engineering practices. To ensure normal production,save retrofitting time and efficiently resolve this problem,a comprehensive analysis was conducted on the equipment structure and electrode plate stability of the electrostatic dehydrator. Innovatively,long hangers were redesigned using upper and lower distance tube connections,and electrode plates were reinforced through localized connections. After retrofitting,the operational reliability of the equipment has been significantly improved,providing a valuable reference for ensuring stable production in future FPSO operations.

Key words: FPSO, electrostatic dehydrator, structural optimization and process improvement
