Study of the impact from dropping a container from the manoeuvering systems on the main deck of a PSV

The topic approached in this paper regards the impact between a container dropped from the manoeuvering systems and main deck of a PSV, without considering the wood material. This study was done to verify the structural resistance of the deck in the most difficult conditions of loading and unloading containers. The dropping test of the container is pretty difficult because it involves a detailed analysis of the stresses that occur in the deck’s structure, as well as in the container’s structure.
