摘要

为研究经典式Spar平台的涡激运动和驰振特性,开展了平台在系泊状态下的水池模型试验,分析不同流速作用下Spar平台的横荡运动特性,并通过对比仅流、仅波浪与波流耦合工况试验结果,分析波流耦合作用对Spar平台涡激运动和驰振运动性能的影响.结果表明:高折合速度的海流使得Spar平台发生驰振运动,相比涡激运动,其振荡周期更长、振幅更大,且具有随机性.波流耦合作用不会改变Spar平台流致运动的具体模式,但是显著影响流致运动的幅值.

Abstract

In order to study the characteristics of vortex-induced motion and galloping of the classic Spar platform, a model test with a mooring system is conducted in basin. The sway motion characteristics of the Spar platform at different current velocities are analyzed. By comparing the results in currents, waves, and wave-current coupled conditions, the coupling effects of current and wave on vortex-induced motion and galloping of the Spar platform are also studied. The results show that galloping is induced by the currents with high reduced velocities. Compared with the vortex-induced motion, the galloping phenomenon has a longer period, larger amplitude, and randomness. The coupling of current and wave would not change the mode of flow-induced motion, but it significantly affects the motion amplitude.

Key words： Spar platform; vortex-induced motion; galloping; model test; hydrodynamics of marine engineering
