Cable Strumming: Some Energy Estimates for a Moored Mine System

Pagination or Media Count:
The report reviews generally much of the work which has been done at NOL and elsewhere on the phenomenon known as Cable Strumming. However, its primary purpose is to examine and estimate for a particular type of system - a one-point moored mine - the orders of magnitude of various energy transformations accompanying the vortex shedding phenomenon responsible for strumming, the various concomitant wave motions on the cable and other dissipative mechanisms effective in degrading the kinetic energy available in the incident fluid stream. A treatment of acoustic wave filtration on the cable is included and shows how noise reduction may result from a proper choice of cable attachment mechanisms.
