"This paper discusses two possible explanations for the loss of the MV Derbyshire during a severe storm, both of which postulate foundering due to structural failure of critical components. One scenario assumes the breakup of the ship due to fatigue failure of longitudinal structural members in the aft portion of the ship, while the other assumes foundering resulting from collapse of hold covers under sea loading."
