Flow-Induced Oscillations of OTEC Mooring and Anchoring Cables: State of the Art

摘要

The objective of this report is to present an overview of the state of knowledge concerned with marine cable strumming oscillations and to apply these finding of the development of design methods for deep ocean cable systems. The report emphasizes recent findings that are relevant to the design of OTEC power plant mooring and riser cable systems. This report is limited in scope to the problems caused by vortex shedding from bluff, flexible structures and cables in steady currents, and the resulting vortex-excited oscillations. Emphasis is placed on outlining the important aspects of the basic phenomena, the development of design procedures, the definition of hydrodynamic force coefficients applicable in practice, and the specification of structural response parameters relevant to marine cable system design.
