Vortex-Excited Vibrations of Marine Cables.

Abstract

A field study of the vortex-induced oscillations of 76.5 ft lengths of various marine cables was conducted. The test site, a sandbar at the mouth of Holbrook Cove in Castine, Maine, was chosen to insure uniformity of current over the entire test length. The flow of the incoming tide produced transverse vibrations of the test cable over a broad range of Reynolds of numbers. Cable tension could be varied as desired. The amplitude, frequency, and general behavior of the cable motions were recorded. The results have been compared to the findings of previous investigators, and interpreted in the light of known properties of the body-wake interaction. A method of testing anti-strumming fairings is also presented, along with the results of such a test. (Author)
