Report of Drop Test Container Offshore Transfer System (COTS)

Abstract

When a Crane-on-Deck (COD) or Temporary Container Discharge Facility (TCDF) is used to transfer containers from a containership to lighters alongside, the possibility of damage to the container and its contents always exists because of relative motions and pendulation. A series of tests were conducted to assess the container's structural limits and the shock levels imparted to the container and its contents as a result of the impact. During testing the containers were dropped from heights which had been calculated to provide representative impact velocities onto a concrete pad, and the appropriate data recorded. Additional tests included drops onto a resilient foam surface in order to evaluate the effectiveness of passive shock mitigation.
