The hull of the submarine named Titan is believed to have collapsed on Sunday due to immense water pressure. Experts will now attempt to determine the exact cause of this failure by analyzing the debris retrieved from the submarine. It is estimated that Titan was situated approximately 3,500 meters below sea level when contact was lost. The enormous weight of water at such depths is equivalent to that of the Eiffel Tower, comprising tens of thousands of tonnes.
In the event of a rupture in the structure, the pressure outside the submarine would be significantly greater than the pressure inside the hull, resulting in the compression of the vessel. When a submarine hull collapses, it rapidly moves inward at an astonishing speed of about 1,500 miles per hour (2,414 kilometers per hour), which is equivalent to 2,200 feet (671 meters) per second. According to Dave Corley, a former US nuclear submarine officer, the complete collapse of the hull takes place in a minuscule time frame of about one millisecond, or one thousandth of a second. To put this into perspective, the human brain instinctually responds to a stimulus in approximately 25 milliseconds, while the rational response, from sensing to acting, is estimated to take about 150 milliseconds.

The air trapped inside the submarine contains a relatively high concentration of hydrocarbon vapors. Consequently, when the hull collapses, the air undergoes auto-ignition, resulting in an explosion following the initial implosion. As a result, human bodies within the submarine are incinerated instantly, turning to ash and dust.
As the investigation into the incident unfolds, special attention will be given to the carbon fiber mid-section of the Titan submarine. Typically, pressure vessels in deep-sea vehicles like this are constructed using sturdy metals such as titanium and shaped in a spherical design to evenly distribute the immense pressure across the passenger compartment. However, in order to accommodate more individuals, the OceanGate sub opted for a cylindrical shape with a carbon fiber tube inserted between two titanium end caps. Carbon fiber is renowned for its strength and is commonly used in the construction of airplane wings and racing cars.
The investigation will focus on whether the tremendous pressure experienced at great depths—over 300 times that of the surface atmosphere—had an adverse impact on the material, exposing flaws in the original fabrication or exacerbating instabilities over repeated dives. The inquiry will likely delve into the practice of non-destructive testing, a technique employed in regular, fine-scale inspections of aircraft to ensure that no cracks develop in the materials or that the layers do not begin to separate.
Photographing the debris from the Titan submarine discovered on the ocean floor and bringing it back to the surface for analysis in a forensic laboratory may enable engineers to identify the specific location within the sub where structural integrity was compromised, leading to the catastrophic implosion. This investigation holds the promise of shedding light on the circumstances that led to the collapse of Titan's hull and potentially informing future design and safety measures in deep-sea exploration.
