Although Titanic is deteriorating while subjected to the natural force of the Atlantic Ocean, it has been preserved relatively well throughout the past ninety-three years. More recent shipwrecks, like the ill-fated Italian luxury liner Andrea Doria which sank in 1956, is in much worse shape structurally than Titanic. The Doria lies in 260 feet of water about 40 miles southwest of Nantucket Island. The relatively shallow depths, strong currents, aluminum-alloy- based superstructure and weather conditions have battered the Doria to the point where the top five deck levels have fallen down to the bottom of the ocean. With its entire superstructure gone, the Doria is now a huge steel hull with all of its once-beautiful infrastructure lying next to it on its starboard side in a vast heap of metallic wreckage.
It is important to put the decay of Titanic in the context of other contemporary twentieth century ocean liner shipwrecks. These once-opulent liner shipwrecks like the Lusitania, the Empress of Ireland and Titanic’s sister, Britannic have all sunk in different parts of the world and been exposed to a variety of different environmental factors. Despite their environmental differences, all of these fine liners are in relatively similar states of deterioration to that of Titanic. Judging by these many differences in environmental conditions, the fact that their states of deterioration are similar may prove to be a mere coincidence.
