 The accident was found to be the result of structural failure of the vessel hull skin and girders at the interface between the transverse stiffening of the engine room and the longitudinal stiffening of the cargo area.This was due to the loading on the structure due to the ship, containers and the rare sea state exceeding the capacity of the hull girders in this area.No deficiencies were found in material or construction and the earlier grounding in 2001 did not contribute to the loss.
