A Characterization of Sway Forces Induced by Close Proximity Ship Towing

Abstract

The scope of this thesis is to characterize the connection forces in the horizontal plane of surface ships in close proximity towing in waves, Strip theory calculations are used in order to predict the hydrodynamic coefficients and wave exciting forces and moments in sway and yaw. The resistance-speed characteristics of the leading ship are used to provide the matching condition between the two ships. The two-parameter Bretschneider spectrum is used to model the sea environment. Results are presented in terms of speed polar and sea state polar plots. An extensive set of parametric studies is presented in regular waves as well as in a wide variety of sea states.
