A compound passive vortex-induced vibration (VIV) control technique, namely the textured pipe-in-pipe (Textured-PIP) system, is introduced in the present study for VIV suppression. This novel system, which is modified from the conventional PIP, includes a smooth inner pipe to transport the natural resources and a textured outer pipe to protect the inner pipe, and the inner and outer pipes are connected together by the optimized springs and dashpots. With such a design, the VIV responses are mitigated by appreciating the suppression mechanisms of tuned mass damper (TMD) and surface roughness. Three-dimensional (3-D) computational fluid dynamics (CFD) analyses are carried out to examine the effectiveness of the proposed method. For comparison and demonstration of the vibration mitigation effectiveness, the responses of a smooth pipe and a textured pipe of the same mechanical properties and mass are also investigated. The results show that the textured-PIP technique can more evidently suppress the VIV compared to the textured pipe.
