Abstract:

Hull girder vibrations are a major concern for ship designers and operators and are a priority in the ship design process. Significant efforts are made to decrease vibrations levels and to reduce damage and noise attributed to vibrations. Attenuation of ship vibration is an important aspect of ship design. This report contains a research plan for ship vibration damping, including analytical calculations, model testing, and full scale measurements. The major elements of this effort included a collection and analysis of vibration damping information b preparation of a model testing and data analysis plan and c preparation of a full-scale testing and data analysis plan. Discussions of specific techniques and recommended procedures are presented in summary form with appropriate references cited. Recommendations represent the state-of-the- art in vibration technology at the time the report was finalized.
