The Titanic sank quickly due to the impact of the iceberg, which damaged a significant part of its hull, allowing water to penetrate and compromise the ship's watertightness.
The hull of the Titanic was constructed from steel and wrought iron, materials that seemed solid at the time but actually had hidden weaknesses. The steel used contained many impurities, notably sulfur, which made it brittle, especially in cold water. At low temperatures, this steel quickly lost its flexibility, much like plastic becomes brittle in the cold. Upon impact with the iceberg, instead of merely bending or deforming, it cracked the hull in several compartments. The rivets, small elements used to connect the steel plates, were also problematic: made from medium-quality iron, they either popped or broke upon impact, contributing to the widening of the hull breach and allowing icy water to flood in rapidly. All of this combined seriously accelerated the sinking of the ship.
On the evening of April 14, 1912, the Titanic was sailing at full speed in an area where icebergs were reported. Despite several radio warnings received by the crew, the ship maintained its course and speed, underestimating the threat. When the iceberg was finally spotted, it was already too late: the abrupt maneuver to avoid it only allowed for a glancing collision with the starboard side of the ship. This impact, which appeared superficial from above, caused significant damage below the waterline, breaching several watertight compartments meant to keep the ship afloat. The cold water of the North Atlantic Ocean quickly rushed in, rapidly pulling the bow down, leading to the inevitable sinking.
The Titanic was equipped with watertight compartments, sort of large bulkheads that were supposed to prevent water from flowing between several areas in case of a breach. The problem was that they didn’t reach high enough, stopping just a few meters above the waterline. As a result, when the bow filled with water and the ship tilted forward, the water simply spilled over the bulkheads, flowing from one compartment to another like simple basins overflowing into each other. In addition, the hull had a major flaw regarding its rivets: the metal used contained too many slag (impurities), which made it brittle, especially in cold water. Therefore, when it collided with the iceberg, the hull opened very easily along a long tear, quickly sealing off several compartments at once.
Disaster management was fraught with human errors. First, the ship's captain, Edward Smith, did not slow down despite repeated warnings of icebergs in the area. Pressured by the desire to set a crossing record, the officers maintained a speed that was too high in risky areas. Next, the crew had not undergone sufficient evacuation drills, which created a lot of confusion during the launching of the lifeboats.
Another major concern was the chaotic management of the lifeboats. Due to poor coordination and the crew's lack of experience, several lifeboats were launched barely filled. This had the dramatic consequence of numerous unnecessary loss of human lives.
Finally, the nearest ship, the Californian, could not intervene quickly because its radio operator had turned off his set during the night. As a result, no one clearly heard or responded to the distress signals sent by the Titanic's operator.
The steel used in the construction of the Titanic contained impurities, making the ship's hull more fragile and brittle in icy waters.
Despite several radio alerts indicating the presence of icebergs in the area, some of them were never transmitted to the Titanic's bridge.
After the collision with the iceberg, many did not immediately realize the severity of the situation. Some passengers even played football with pieces of ice that had fallen onto the deck.
The Titanic had a heated swimming pool, the first of its kind on an ocean liner, reserved for first-class passengers.
Following the tragedy, several international regulations were strengthened: a minimum number and increased capacity of mandatory lifeboats, a continuous radio watch system on board ships, and the establishment of the International Ice Patrol to monitor icebergs in the North Atlantic.
Yes, increased vigilance and better consideration of the warnings provided could have potentially allowed for a quicker response. Similarly, a reduced speed would have facilitated an effective evasive maneuver, thereby minimizing the consequences or possibly even avoiding the collision altogether.
Yes, the Titanic was carrying only 20 lifeboats, which was in accordance with the legal requirements of the time but insufficient for the total capacity of the ship. This shortfall unfortunately amplified the number of casualties during the disaster.
Studies have revealed that the steel used in the hull of the Titanic became extremely brittle at low temperatures, which were precisely the conditions encountered during the collision with the iceberg. Thus, the materials indeed exacerbated the extent of the damage that occurred.
Initially, the severity of the situation was underestimated, which resulted in valuable time being lost before the first distress messages were sent. This delay contributed to reducing the chances of assistance from nearby vessels.
Although designed to withstand several flooded compartments, the extent and location of the breaches created by the iceberg compromised too many adjacent parts of the ship, exceeding the limits anticipated by the engineers. Furthermore, the watertight bulkheads did not extend up to the main deck, facilitating the rapid spread of water.
