SS Andrea Doria




SS Andrea Doriawas an ocean liner for the Italian Line home ported in Genoa, Italy, most famous for its sinking in 1956, when 46 people died. Named after the 16th-century Genoese admiral Andrea Doria, the ship had a gross register tonnage of 29,100 and a capacity of about 1,200 passengers and 500 crew. For a country attempting to rebuild its economy and reputation after World War II, Andrea Doria was an icon of Italian national pride. Of all Italy's ships at the time, Andrea Doria was the largest, fastest and supposedly safest. Launched on 16 June 1951, the ship undertook its maiden voyage on 14 January 1953. ndrea Doria had a length of 212 m (697 feet), a beam of 27 m (90 ft), and a gross register tonnage of 29,100. The propulsion system consisted of steam turbines attached to twin screws, enabling the ship to achieve a service speed of 23 knots (43 km/h), with a top speed of 26 knots (48 km/h). Andrea Doria was not the largest vessel nor the fastest of its day: those distinctions went to the RMS Queen Elizabeth and the SS United States, respectively. Instead, the famous Italian architect, Minoletti, designed the Andrea Doria for luxury.
Because it sailed the southern Atlantic routes, Andrea Doria was the first ship to feature three outdoor swimming pools, one for each class (first, cabin and tourist). The ship was capable of accommodating 218 first-class passengers, 320 cabin-class passengers, and 703 tourist-class passengers, and 563 crew on ten decks. With over $1 million spent on artwork and the decor of the cabins and public rooms, including a life-size statue of Admiral Doria, many consider the ship to have been one of the most beautiful ocean liners ever built next to the two Queens, RMS Queen Elizabeth and RMS Queen Mary.
 The ship was also considered one of the safest ships ever built. Equipped with a double hull, Andrea Doria was divided into eleven watertight compartments. Any two of these could be filled with water without endangering the ship’s safety. Andrea Doria also carried enough lifeboats to accommodate all passengers and crew. Furthermore, the ship was equipped with the latest early warning radar. However, and despite its technological advantages, the ship had serious flaws concerning its seaworthiness and safety.
Confirming predictions derived from model testing during the design phase, the ship developed a huge list when hit by any significant force. This was especially apparent during its maiden voyage, when Andrea Doria listed twenty-eight degrees after being hit by a large wave off Nantucket. The ship's tendency to list was accentuated when the fuel tanks were nearly empty, which was usually at the end of a voyage.
This stability issue would become a focus of the investigation after the sinking, as it was a factor in both the capsizing and the crew's inability to lower the port-side lifeboats. The bulkheads of the watertight compartments extended only up to the top of A Deck, and a list greater than 20 degrees allowed water from a flooded watertight compartment to pass over its top into adjacent compartments. In addition, the design parameters allowed the lowering of the lifeboats at a maximum 15-degrees list. Beyond this, up to half of the lifeboats could not be deployed. Andrea Doria started as Yard No. 918 at Ansaldo Shipyard in Genoa. On 9 February 1950, the ship's keel was laid on the No. 1 slipway, and on 16 June 1951, Andrea Doria was launched. During the ceremony, the ship's hull was blessed by Giuseppe Siri, Cardinal Archbishop of Genoa, and christened by Mrs. Giuseppina Saragat, wife of the former Minister of the Merchant Marine Giuseppe Saragat. However, amid reports of machinery problems during sea trials, Andrea Doria's maiden voyage was pushed back from 14 December 1952, to 14 January 1953.
During the ship's maiden voyage, it encountered heavy storms on the final approach to New York, listing a full twenty-eight degrees. Nevertheless, Andrea Doria completed its maiden voyage on 23 January only a few minutes behind schedule, afterwards, Andrea Doria became one of Italy's most popular and successful ocean liners as it was always filled to capacity. By mid-1956, it was making its 100th crossing of the Atlantic.
 On the evening of Wednesday, 25 July 1956, Andrea Doria, commanded by Captain Piero Calamai, carrying 1,134 passengers and 572 crew, was heading west towards New York. It was the last night of a transatlantic crossing from Genoa that began on 17 July: the ship was expected to dock in New York the next morning.
At the same time, MS Stockholm, a smaller passenger liner of the Swedish American Line, had departed New York about midday, heading east across the North Atlantic Ocean toward Gothenburg, Sweden. As Stockholm and Andrea Doria were approaching each other head-on, in the heavily used shipping corridor, the westbound Andrea Doria had been traveling in heavy fog for hours. The captain had reduced speed slightly from 23.0 to 21.8 knots (42.6 to 40.4 km/h), activated the ship's fog-warning whistle, and had closed the watertight doors, all customary precautions while sailing in such conditions. However, the eastbound Stockholm had yet to enter what was apparently the edge of a fog bank and was seemingly unaware of it and the movement of the other ship hidden in it. As the two ships approached each other, at a combined speed of 40 knots (74 km/h), each was aware of the presence of another ship but was guided only by radar; they apparently misinterpreted each other's course. There was no radio communication between the two ships, at first.
The original inquiry established that in the critical minutes before the collision, Andrea Doria gradually steered to port, attempting a starboard-to-starboard passing, while Stockholm turned about 20 degrees to its starboard, an action intended to widen the passing distance of a port-to-port passing. In fact, they were actually steering towards each other — narrowing, rather than widening, the passing distance. Compounded by the extremely thick fog that enveloped the Doria as the ships approached each other, the ships were quite close by the time visual contact had been established. By then, the crews realized that they were on a collision course, but despite last-minute maneuvers, they could not avoid the collision.
In the last moments before impact, Stockholm turned hard to starboard and was in the process of reversing its propellers, attempting to stop. The Doria, remaining at its cruising speed of almost 22 knots (41 km/h) engaged in a hard turn to port, its captain hoping to outrun the collision. At approximately 11:10 PM the two ships collided, the Stockholm striking the side of the Andrea Doria. When Andrea Doria and Stockholm collided at almost a 90-degree angle, Stockholm's sharply raked ice breaking prow pierced Andrea Doria's starboard side approximately midway of its length. It penetrated three passenger cabins, numbers 52, 54 and 56, to a depth of nearly 40 feet (12 m), and the keel. The collision smashed many occupied passenger cabins and, at the lower levels, ripped open several of Andrea Doria's watertight compartments. The gash pierced five fuel tanks on Andrea Doria's starboard side and filled them with 500 tons of seawater. Meanwhile, air was trapped in the empty tanks on the port side, contributing to a severe, uncorrectable list. The ship's large fuel tanks were mostly empty at the time of the collision, since the ship was nearing the end of its voyage, but all the empty fuel tanks did was help the list increase.
Meanwhile, on the bridge of Stockholm, immediately after the impact, engines were placed at ALL STOP, and all watertight doors were closed. The ships were intertwined for about 30 seconds. As they separated, the smashed bow of the stationary Stockholm was dragged aft along the starboard side of the Doria, which was still moving forward, adding more gashes along the side. The two ships then separated, and the Doria moved away into the heavy fog. Initial radio distress calls were sent out by each ship, and in that manner, they learned each others' identities. The world soon became aware that two large ocean liners had collided.  Immediately after the collision, Andrea Doria began to take on water and started to list severely to starboard. Within minutes, the list was at least 18 degrees. After the ships separated, the Captain quickly brought the engine controls to ALL STOP. Many people believe that one of the watertight doors to the engine room was missing, though this issue was later determined to be moot. Much more importantly, however, crucial stability was lost by the earlier failure, during routine operations, to ballast the mostly empty fuel tanks as the builders had specified. Owing to the immediate rush of seawater flooding the starboard tanks, and the fact that the port tanks were empty because the crossing was almost over, the list was greater than would otherwise have been the case. As it increased over the next few minutes, to 20 degrees or more, Captain Calamai realized there was no hope for his ship unless the list could be corrected.
In the engine room, engineers attempted to pump water out of the flooding starboard tanks to no avail. There was only a small amount of remaining fuel, and the intakes to pump seawater into the port tanks were now high out of the water, making that procedure to attempt to level the ship impossible. Progressive loss of generators due to flooding as the water rose in the engine room reduced the ability to pump even more.
On Stockholm, the entire bow was crushed, including some crew cabins. Initially, the ship was dangerously down by the bow, but emptying the freshwater tanks soon raised the bow to within 4 inches (10 cm) of normal. Once the evacuation was complete, the captain of Andrea Doria shifted his attention to the possibility of towing the ship to shallow water. However, it was clear to those watching helplessly at the scene that the stricken ocean liner was continuing to roll on its side.
After all the survivors had been transplanted onto various rescue ships bound for New York, Andrea Doria's remaining crew began to disembark—forced to abandon the ship. By 9:00 AM. even Captain Calamai was in a rescue boat. The sinking began at 9:45 a.m. and by 10:00 that morning Andrea Doria was on her side at a right angle to the sea. The ship fully disappeared into the Atlantic at 10:09—almost exactly eleven hours after the collision with Stockholm took place. The starboard side dipped into the ocean and the three swimming pools were seen refilling with water. As the bow slid under, the stern rose slightly, and the port propeller and shaft were visible. As the port side slipped below the waves, some of the unused lifeboats snapped free of their davits and floated upside-down in a row. It was recorded that Andrea Doria finally sank 11 hours after the collision, at 10:09 AM on 26 July. The ship had drifted 1.58 nautical miles (2.93 km) from the point of the collision in those 11 hours. Aerial photography of the stricken ocean liner capsizing and sinking won a Pulitzer Prize in 1957 for Harry A. Trask of the Boston Traveler newspaper. Due to the luxurious appointments and initially good condition of the wreck, with the top of the wreck lying initially in 160 feet (50 m) of water, Andrea Doria has been a frequent target of treasure divers. It is commonly referred to as the "Mount Everest of scuba diving." The depth, water temperature and currents combine to put the wreck beyond the scope of recreational diving. The skills and equipment required to successfully execute this dive, such as use of mixed gases and staged decompression, put it in the realm of only the most experienced technical divers. As of 2010, years of ocean submersion have taken their toll. The wreck has aged and deteriorated extensively, with the hull now fractured and collapsed. The upper decks have slowly slid off the wreck to the seabed below. As a result of this transformation, a large debris field flows out from the hull of the liner. Once-popular access points frequented by divers, such as Gimbel's Hole, no longer exist. Divers call Andrea Doria a "noisy" wreck, as it emits various noises due to continual deterioration and the currents' moving broken metal around inside the hull. However, due to this decay new access areas are constantly opening up for future divers on the ever-changing wreck.
After years of removal of artifacts by divers, little of value was thought to remain. Significant artifacts recovered include the statue of Genoese Admiral Andrea Doria, for whom the ship was named. It was removed from the first-class lounge having been cut off at the ankles to accomplish this. Examples of the ship's china have long been considered valuable mementos of diving the wreck. The ship's bell is normally considered to be the prize of a wreck. This ship carried three bells: one bell located on the bridge, and two much larger ceremonial bells located on the fore and aft decks. The ship's stern bell was retrieved in the late 1980s by a team of divers led by Bill Nagle. On June 26, 2010, a diver from New Jersey, Carl Bayer, discovered the bridge bell lying on the bottom at 241 feet. He recovered it with assistance from Ernie Rookey, also from New Jersey. The bell, measuring 16 inches tall and weighing 73.5 pounds, was possibly used to signal fog on the night of the collision. The forward bell remains undiscovered. It has for years been thought to be in the ship's paint locker where it was stored during ocean crossings, but recent reports indicate that that part of the ship has collapsed in on itself and the forward bell may never be found.
