The Titan submersible had a tragic end. There were five people on board and they experienced a traumatic death due to the tragedy. The Titan submersible lost contact with the support ship while diving to the Titanic wreck site in the North Atlantic. The US Coast Guard and OceanGate Expeditions announced all five people on board are presumed dead.
What are the main causes of the tragedy? Let’s find out.
Previously, the Coast Guard said rescuers had discovered a wreckage in the search area, where teams searching for the missing Titan submersible were moving toward the wreck of the Titanic.
Debris was found on the ocean floor where the Titan submersible is located by a remotely controlled underwater search vehicle. This fragment was found about 488 meters below the tip of the Titanic on the ocean floor.
USCG Rear Adm. John Mauger announced Thursday that debris found indicates a possible “catastrophic explosion of the ship.”
How did Titan explode?
Although the exact nature of the incident is yet to be determined, experts say the explosion could have occurred on the first day of the dive, which was on Sunday.
Titanium is designed with titanium and carbon fiber. These materials are said to be able to withstand pressure at depths of about 4,000 meters. The hull is designed to protect the crew from the pressure of the water.
The water pressure at a depth of 3,800 meters at the Titanic wreck site is about 400 atmospheres. This is great pressure.
Director of the Shipbuilding Center for Integrated Engineering at the University of Adelaide, Eric Fusil, said: “Any deep diver knows how unforgiving the abyssal plain is: going on the seabed is even more challenging. more conscious than going into space from a technical perspective”. .
Experts cannot help but wonder about using carbon fiber and titanium for deep diving because they both have different properties.
Why do experts question the use of carbon fiber and titanium?
This is because both materials have distinct properties. On one hand, Titanium is elastic in nature, it can adapt to countless stresses and pressures without any permanent strain on the titanium itself. However, carbon fiber is inelastic in nature. It is hard and can therefore crack under pressure.
The difference in both of these materials, as Eric Fusil said, may have created defects in the hull. Although the exact nature of the incident is still unknown, experts of this opinion speculate that the defect created in the ship’s hull led to an instantaneous explosion due to the high pressure underwater. Fusil further assumed that in a time frame of less than a second, the Titan ship would be crumpled from all sides, pushed down by the weight of the 3,800m high water column.
