![]() Both in-plane and out-of-plane signals were recorded. The riser is instrumented with Fiber Bragg Grating (FBG) strain gauges along the pipe length and circumference. The model test setup includes a fully instrumented pipe, a planar motion mechanism (PMM) which simulates the vessel motion. The SLWR pipe was carefully scaled and designed to meet the test objectives. The paper presents the challenges and experiences during the design and execution of this complex model test campaign. In total, five (5) different configurations were tested. ![]() The scopes of the model test are to measure the response of the riser under floater motions and measure any VIV. The objective of the model test is to obtain hydrodynamic coefficients for the straked pipe and to better understand the global dynamic behavior of pipe with distributed buoyancy modules due to vessel induced motion and vortex-induced-vibration (VIV)., and thus advance its design. A comprehensive test on straked riser with buoyancy modules has been planned, designed, and executed in a wave basin. However, SLWR technology is still new, and has limited test data and design experience on the critical riser location that is fitted with buoyancy modules. ![]() Steel Lazy Wave Riser (SLWR) configuration has recently becoming an attractive riser solution for deep water developments.
