A Review of Experimental Methods for Investigation on VIV of Submarine Pipeline Span
海底悬跨管线涡激振动实验方法探讨

As development of Chinese offshore oil industry, the investigation on vortex induced vibrations (VIV) of submarine pipeline span gets more and more public recognition. A comprehensive review of progress of experimental method, measurement technique and analysis methods for VIV of submarine pipeline span is presented in this paper. Some difficult problems in VIV experiment are analyzed in detail. The design principle and parameters for VIV experiment in a wave current tank, where the excitation would be either regular waves, uniform currents, or a combination of above two are discussed. Procedures for designing experiments in a wave current tank are proposed. Designed experiments, that have been performed in a wave current tank located at the State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology (DUT), was focused mainly on the transition from the first dominant mode to the second one and the vibration characteristics in the range of transition. Finally, some suggestions are made for further research.
