Transient dynamic analysis and slamming bending moment evaluation of a fast ferry

摘要

The knowledge about slamming and its effects on fast monohull vessels is limited by the lack of historical reference data, provided that it is not possible to adopt for such vessels the same standards used for conventional ships. This paper describes the development of an integrated numerical calculation procedure for the evaluation of slamming hydrodynamic loads on fast monohull vessels and of the subsequent transient dynamic response of the hull girder in terms of flexural longitudinal bending moment amidship. The procedure has been applied to the study of the MDV-3000 fast ferry, designed and built by Fincantieri. A validation of the procedure is also presented through a comparison with design values from Rules and experimental results from sea trials.
