The MS München was a German LASH (Lighter Aboard SHip) carrier operated by Hapag-Lloyd, launched on May 12, 1972, at the Cockerill Yards in Hoboken, Belgium. She was the only LASH vessel of her kind under the German flag. Built with a length typical of large cargo ships of her class, she was designed to transport standard cargo in lighters, providing a high degree of flotation safety due to her specialized design. München’s construction was completed and she was delivered to her owners in September 1972, with her maiden voyage departing Bremerhaven for the United States on October 19, 1972. Her sister ship, MS Bilderdijk, was also built at the same yard and later renamed Rhine Forest, serving until her retirement in 2007. On her 62nd voyage, departing Bremerhaven on December 7, 1978, München was bound for Savannah, Georgia, carrying a cargo of steel products stored in 83 lighters, along with a crew of 28. Notably, she also transported a replacement nuclear reactor-vessel head for Combustion Engineering, Inc. During her transatlantic crossing through the North Atlantic storm that had been raging since November, München was considered highly resilient, as LASH ships were regarded as practically unsinkable due to their advanced flotation capabilities. However, during the night of December 11–12, 1978, München encountered severe weather conditions. Radio communications revealed she was experiencing damage and a significant list—reported as 50 degrees to starboard—without power or propulsion. SOS signals and Mayday calls were received, but the ship’s position was uncertain, and she ultimately disappeared amidst the storm. Extensive international search and rescue efforts, involving over 100 ships and multiple aircraft, failed to locate her or her crew. The last recovered objects included life rafts, life vests, and the damaged starboard lifeboat, which indicated she had been struck by a massive rogue wave—an event now believed to have caused her sinking. The investigation suggested that a rogue wave between 80 and 100 feet high likely struck München, breaking her bow and superstructure, tearing loose her lifeboat, and flooding her. The ship then drifted helplessly for hours before capsizing or sinking due to progressive flooding. Her wreck remains undiscovered today. The loss of München highlighted the potential danger posed by rogue waves in the deep ocean, contributing to increased scientific understanding of such phenomena. Her sinking was featured in documentaries and remains a significant case study in maritime safety and wave dynamics.
