Model Tests and Numerical Simulation of Ship Capsizing in Following Seas

摘要

This report presents some comparisons of experimental data and computational simulations of the severe roll motion and capsizing of ships operating in following seas. Earlier reports have described experiments conducted using radio-controlled ship models in San Francisco Bay for the purpose of studying the phenomenon of ship capsizing and the initial development of a computer simulation of the same phenomenon. The present report describes experiments conducted in the towing tank using three models: a Mariner class cargo ship, a model of the SL7 container ship, and a west coast crab fishing boat. The principal objectives of these experiments was to provide data with which to test the simulator program. In addition to these experiments, the report describes some studies made using a simple one-degree-of-freedom simulator program. A final Appendix contains a description of the simulator program and instructions for its use. (Author)
