Impact and Operational Tests of the Container Hopper

Abstract

The container hopper is designed to attenuate the swinging motions of a maritime van container suspended from a floating crane and then guide the container directly onto a truck trailer. It was developed under the auspices of the Marine Corps Development and Education Command and the Naval Facilities Engineering Command. There were two major phases in the development of the hopper. The first consisted of impact tests on one of the hopper shock absorbers. The second phase was a fully operational evaluation of the hopper during the OSDOC II (Offshore Discharge of Containership II) exercise in which a containership anchored one mile off the Virginia coast was unloaded with a floating crane. The crane lowered containers through the hopper onto flatbed semi-trailers, MILVAN chassis, and tandem rigs. Like the crane, the hopper and trucks were on a floating platform. Loading times as short as one minute were achieved.
