Numerical simulation of drilling riser vortex induced vibration characteristics in deepwater
摘要
Abstract
Offshore oil and gas exploration and development are undergoing a strategic shift to deep and ultra-deep waters. As a critical part of deepwater oil and gas development, deepwater drilling riser will surely be confronted with the major safety problem of vortex induced vibrationg(VIV), and fatigue failure and it is attracting widespread attention. Fluid-structure coupling based on reifned lfow ifeld simulation with coupled structural dynamic response is an inevitable trend to accurately analyze the VIV characteristics of riser. This paper summarizes some of the research results on numerical simulation during the “Eleventh Five-Year” period and the ongoing research projects in the “Twelfth Five-Year” period. To address the VIV problems of risers in simpliifed and practical sizes, a high-precision lfuid-structure coupling analysis technology is proposed, and reliable physical model, mathematical model and numeri-cal simulation are built for analysis of riser VIV. The comparative experiment veriifes the reliability of the models. The large number of numerical simulation researches on the VIV of drilling riser under simpliifed and practical cases (sea conditions, structure, size, etc.) show the VIV characteristics of riser with practical size under several typical ocean currents with a high reynolds number high under actual sea conditions, such as shear lfow, subcritical lfow and critical lfow, as well as the controlling effect of top tension on the VIV of riser in some way.关键词
