Damping arises in the context of ship response from (a) the structural properties of the hull and its contents and (b) hydrodynamic effects. Between them, these two sources of dissipation play a dominant role in ship response to waves and to propeller excitation. This paper reviews present knowledge of (a), damping of internal origin from the aspects of material hysteresis, dry friction of reveted and welded joints and cargo damping. A quantitative specification for determining various levels of viscous damping is developed and the paper concludes with a brief comparison of the more important empirical formulae used in representation of damping.
