The paper describes experiments performed to evaluate the performance of two vortex suppression devices fitted to a flexible tubular model in conditions of waves and current. The results are compared between suppressed and unsuppressed models on the basis of drag, lateral force, displacements and bending moments. The two devices considered are a simple helical strake, and the axial rod cage suggested by Dr. M. M. Zdravkovich of Salford University. The axial rod cage shows excellent vortex suppression characteristics.
