Study of Vortex-Induced Vibration of SCRs for a Spar Platform with the Application in South China Sea

doi:10.12087/oeet.2095-7297.2018.03.06

Abstract

Abstract: Spar platform is a new type of floating platform for deep and ultra-deep water applications. It is suitable for the exploration, development and production of oil and gas in the South China Sea. Steel catenary risers (SCRs) are widely used allover the world due to its structure simplicity, high reliability and economy. SCR's fatigue damage caused by vortex-induced vibration (VIV) is vital to the safety of SCRs and the entire platform. We consider the environmental conditions in the South China Sea and study the VIV of SCRs for a Spar platform. The layout and configuration of SCRs are introduced at first. Then the VIV fatigue of 18-inch SCR is analyzed. Furthermore, the sensitivity of key parameters is investigated. This research will provide a good reference for deepwater riser design.
