Das Kentern von Schiffen in unregelmässiger längslaufender See
Doctoral dissertation published as Institut für Schiffbau Hamburg Bericht Nr. 249 (December 1968) by Sigismund Kastner, presenting a statistical-computational method for analyzing ship capsizing in irregular longitudinal seas. The nonlinear equation of rolling motion is solved using an analog computer, which the author justifies at length (Chapter 6) for its ability to handle nonlinear righting-lever curves directly, simulate oscillating systems without iteration, and dramatically compress computation time versus digital methods. Results include statistical distributions of time-to-capsize as a function of ship parameters such as metacentric height, damping, freeboard, and speed.
