Title: Experiments with a steel catenary riser model in a towing tank
Author: Morooka, CK

Abstract: A model test with a steel catenary riser (SCR) was concluded in a towing tank. The main purpose of the experiment was to gain further understanding of the global SCR dynamic behavior with vortex-induced vibration (VIV). To this end, a large model scale factor (250) was considered. The mass and stillness of the riser model are very low, and the Reynolds number in the experiment ranged from 900 to 600. The experimental results demonstrated the influence of traveling waves on the cross-flow response of the riser model, which was verified by several analytical methods. This study provided important indications that the sources of the traveling waves (power-in regions) seem to change position along the riser length over time. Finally, the experimental design, data processing procedure, experimental set-up, and results are described in detail. (C) 2013 Elsevier Ltd. All rights reserved.
