Abstract (german): This thesis reconstructs the sinking of the RoPax Ferry MV Estonia on September 28th 1994, with a strong focus on describing the chain of events that caused the eventual sinking, and how the ship sank. Once the sinking is understood, this thesis explores possible safety improvements that should be implemented in the design of new vessels of this type. The investigation is based on a combination of testimonies of survivors as well as numerical calculations based on the framework of the testimonies. Sea loads on the bow visor broke its locks and hinges. Consequently, the bow visor separated from the vessel and with it the bow ramp was ripped open because of boxlike-housing of the visor at top of the bow ramp. The loss of watertight integrity was followed by massive water ingress on the Main Car Deck and MV Estonia partially capsized to a quasi-static equilibrium floating condition. This persisted for a few minutes, whilst several side ventilation openings became immersed. From that time on, a progressive flooding started, leading to consecutively submerged windows in the superstructure failing and allowing further water ingress. Finally, at a list of about 130°, the ferry hit the sea floor stern first and the bow subsided soon after.
