Animation and Simulations/ Andrea Doria

The Andrea Doria was an Italian cruise ship built in the early 1950's and had navigated her normal route across the Atlantic to New York exactly 100 times before. On July 25, 1956 the Stockholm, a Swedish liner bound for her homeland, collided with the Andrea Doria in a dense fog off the island of Nantucket.

The Discovery Channel asked JMS to recreate the incident by performing a forensic engineering analysis and illustrate the findings with 3D-computer simulations. In this way, JMS would explain why the ships collided, describe the extent of damage to both ships and how it may have caused the Doria to sink the way that it did.

The damage to the Doria was very severe. Most of the 51 passengers who lost their lives as a result of the collision died almost instantly when the ice-strengthened bow of the Stockholm penetrated 3 cabin decks to a depth of nearly 40 feet.

The damage to the Doria was so vast that it caused a near instantaneous flood of seawater into empty starboard fuel tanks. This sudden non-symmetrical flooding forced the ship to list more than 20degrees to starboard and caused non-watertight upper decks, now exposed by the damaged hole, to become submerged. This continual flooding, listing and submerging of decks eventually overwhelmed the vessel. In less than 10 hours after the collision the Andrea Doria plunged to her grave in nearly 300 feet of water.
