Catastrophic implosion of Titan submarine is explained by Physics; check it out

In the recent tragic incident, the Titan submarine, which belongs to the company OceanGate, suffered a catastrophic implosion, resulting in the death of all five people on board.

The submarine was about to undertake an expedition to visit the wreckage of the Titanic when the fatal event occurred. This event raised serious questions about the causes of this tragedy.

Implosion is a phenomenon that occurs when the internal pressure of a submarine exceeds the resistance of the hull, releasing an overwhelming amount of energy and resulting in instant death for the occupants.

The resistance of submarine hulls to extreme ocean conditions depends on their design and the materials used in their construction.

Conventional materials such as steel, titanium and aluminum have typically been shown to withstand high underwater pressures. However, the Titan submarine’s hull took an experimental approach, making predominant use of carbon fibers.

Although these fibers are known for their lightness and ability to offer more internal space, their suitability for use in marine environments is still unknown.

Unlike titanium, which is elastic and adapts well to changes in pressure, carbon fiber is rigid and inflexible, and is not suitable for withstanding the elasticity of deep diving.

Therefore, the combination of these materials with different properties can compromise the integrity of the hull, resulting in implosions like the one that occurred with the Titan, which faced a pressure of 400 kg per square centimeter.

Implosion occurs when the carbon fiber reinforcement layers separate, in a phenomenon known as “delamination,” due to intense underwater pressure. During deep dives, the pressure is overwhelming and reaches the submarine quickly, leading to implosion in less than a second.

In light of this tragic event, the need to carry out rigorous testing and carefully select the materials used in the construction of submarines becomes evident.

The use of unproven materials, such as carbon fibers in the case of Titan, should be approached with caution and subjected to further scrutiny. Deep-sea exploration requires an approach that prioritizes safety in the face of extreme ocean pressures.
