This report documents development of energy damping alignment arms for solution of dynamic alignment problems occuring during freight operations at sea using spreader bars for lifting ISO and freight containers. This report considers solutions to the dynamic alignment problem in positioning the spreader bar for lifting ISO and freight containers. Both passive and active systems were considered. Three passive system concepts were evaluated, with conclusions and recommendation for implementation of one of the concepts. Additionally, the report documents a preliminary force study conducted to the spreader bar container system.
