A procedure is developed for selecting design criteria for the berthing energy fender systems at ferry landings. In particular, end berthing arrangements are considered. A sample of 568 landing events are reviewed to find the distribution of approach velocity for kinetic energy calculations. An upper bound for the berthing coefficient is also identified. The design procedure is developed that involves 1) identification of the upper limits of the approach velocity by analyzing a sample of berthing events, 2) selection of a safety factor by making systematic judgments, 3) selection of a berthing coefficient based on experimental results, and 4) selection of design berthing energy using the kinetic energy formula. Further research is recommended to improve the placement of landing aids and to develop design criteria for other landing structures. The contents of this final report are presented in the following sections: Summary; Conclusions and Recommendations; Background; Review of Previous Work; Procedures; Discussion; and Application and Implementation.
