During the evaluation of the joint ArmyNavy Balloon Transport System conducted off of Green Beach, Ft. Story, Virginia, the David W. Taylor Naval Ship Research and Development Center DTNSRDC was tasked to measure ship motions on some of the vessels used in the operation. The vessels instrumented by DTNSRDC were the Armys BDL LT. COL. JOHN U. D. PAGE, the LST 1180 USS MANITOWOC, and two Navy LCUs of the 1610 series 1658 and 1659. Two principal configurations to remove Milvan containers from the vessels were investigated. The first was a ship to shore maneuver for which DTNSRDC instrumented the BDL and the LCU 1659. The second was a ship to lighter operation for which DTNSRDC recorded ship motions on the LST 1180 and the LCUs 1658 and 1659. Throughout the operations, the motions of the vessels investigated were, in general, rather small with the largest motions occurring aboard the LCUs when they were fendered off of the larger BDL and LST with Yokohama pneumatic fenders. The vessel motions were not the limiting factor in the operation of the balloon transfer system. Observations indicated that the ability to get the vessels into the proper position and weather operational limits of the balloon were of greater significance in the successful transfer of Milvan containers from the vessels.
