Linear Theory of Transverse Cable Dynamics at Low Frequencies

摘要

This report documents a study of the horizontal motion of the downstream end of a towed cable when the motion of the towing vessel is known. The dynamic position of the downstream end of the cable is a consequence of the random crosstrack meandering of the towing vessel as it imperfectly maintains a constant course. The specific purpose of the study was to supply a method to predict the horizontal motion. Other contributors to cable dynamics, such as ocean current, are not addressed. Keywords include: Ocean Engineering, Towing Hydrodynamics, and Cables.
