Abstract

Freely hanging water intake risers (WIRs) are widely used in deep-sea oil and gas development for its economic efficiency. Due to interaction between vessel motion and internal flow,WIRs have strong dynamic responses in inline (IL) direction and form a relative oscillatory current between them and surrounding water. This oscillatory flow is very likely to induce vortex-induced vibration (VIV) of WIRs in cross flow (CF) direction. Here,large-scale model tests for a freely hanging water intake riser (WIR) were performed in an ocean basin to investigate the riser’s dynamic responses under interaction between vessel motion and internal flow. In tests,fiber brag grating (FBG) strain sensors were used to record strain time histories of some points at the riser surface in CF and IL directions. The results showed that large diameter WIRs’VIV occur under actions of internal flow and oscillation flow field; within the internal flow speed range of tests here,the action of internal flow can be neglected,the vessel motion-induced VIV has an instability.
