A theory has been developed which could aid Navy materials handling specialists in their effort to evaluate load transfer systems for a modular port facility. The theory predicts the horizontal response of an unrestrained, wire suspended load in regular and random seas. The line length is allowed to vary with time, hence the resulting load response in random seas is characterized as a non-stationary random process. The analysis is used to predict the motion of a load freely suspended from the boom of a Navy 100-ton floating crane. The results from the analysis and from full scale tests at sea confirm the fact that motion of unrestrained loads is a serious problem in even moderate sea states. Taglines or other means of restraint will be required from inception through completion of each load transfer. (Author)
