Structural Design and Response in Collision and Grounding

The results summarized in this paper represent the work of SNAME Ad Hoc Panel #6 convened under the SNAME Technical and Research Program. This is a summary and overview paper. Topics discussed will be addressed individually and in more detail in later publications. The 2nd International Conference on Collision and Grounding of Ships, to be held in Copenhagen, July 1-3,2001, will also present and discuss many of the results of this panel and other related research.

The paper discusses four primary areas of panel work: collision and grounding models, data, accident scenarios and design applications. A probabilistic framework for assessing the crashworthiness of ships is presented. Results obtained from various grounding and collision models are compared to validating cases and to each other.

Data necessary for proper model validation and probabilistic accident scenario development are identified. Deformable striking-ship bow models and their application are described. Potential design applications and alternatives for improving crashworthiness are discussed.
