## 1 Introduction  
Deep-water jacket platforms are usually constructed horizontally on land and are mainly affected by wind loads in the horizontal direction. When the wind flows in the direction perpendicular to the pipe, it will not only generate drag force in the downstream direction, but also form vortices on the surface of the structure. The alternating appearance of the vortex makes the pipe vibrate transversely; that is, wind-induced vortex-induced vibration (VIV). During the construction of the jacket, some pipes are in a state of unilateral restraint, the natural frequency is low, and the wind speed at which vortex-induced resonance occurs is also reduced. Therefore, the influence of wind-induced VIV should be considered. Many scholars have studied the problem of flow around a cylinder considering a high Reynolds number. [PERSON] et al. [1] used the standard \(k\)-\(\epsilon\) model to simulate the two-dimensional flow around a cylinder with \(Re=10^{6}\) and compared it with the calculation results of the large eddy simulation. They found that the standard \(k\)-\(\epsilon\) model can better predict the flow around the cylinder in the critical and supercritical areas. [PERSON] et al. [2] used the SST \(k\)-\(\omega\) model combined with the overset grid to simulate the two-dimensional flow around the cylinder in the range of \(Re=6.31\times 10^{4}\)-\(7.57\times 10^{5}\) and compared the experimental results, which proved the feasibility of using the overset grid to study the VIV problem. [PERSON] et al. [3,4] modified the SST \(k\)-\(\omega\) model of [PERSON] [5], which confirmed that the modified model has better simulation performance. [PERSON] et al. [6] measured the wind pressure distribution along the length of the cylinder and the lift coefficient of the cylinder in the range of \(Re=10^{5}\)-\(4.6\times 10^{5}\) in the wind tunnel test. Theyfound that the flow state will change along the length of the cylinder, and the separation and reattachment of the bubbles can cause unstable changes in lift and pressure. Vortex-induced vibration suppression methods can be divided into two categories: passive suppression methods and active suppression methods. The passive suppression method can suppress vortex shedding by changing the surface shape of the structure or installing accessories to change the flow field distribution of the structure, or structural vibration can be directly suppressed by installing vibration dampers and shock absorbers. The passive suppression method is simple to design and implement and has low cost, but it cannot effectively respond to changes in the external environment in time [7]. The active suppression method uses real-time monitoring of structural vibration response and flow field and actively interferes with structural vibration and flow field distribution so as to suppress vibration. The active suppression method can adjust control strategies and parameters according to environmental changes and has strong adaptability to the environment. However, active suppression requires external energy input, complex technology, and high cost. These suppression devices have been widely used in offshore pipelines, but there are few suppression devices used on jacket pipes. [PERSON] et al. [8] studied the flexible riser with helical strakes through experimental methods. From the change of cross-flow vibration frequency, it was concluded that the helical strakes can well suppress the occurrence of vortex-induced vibration. [PERSON] et al. [9] simulated the suppression effect of water drop fairing and short tail fairing on vortex-induced vibration by using the SST model and the URANS method modified by the arbitrary Lagrangian-Eulerian (ALE) method. The numerical results obtained were the same as the experimental results. [PERSON] et al.
