Diving into the Depths: OceanGate Expedition and the Tragic Titanic Submarine Tour

In 2009, an American aerospace engineer named Stockton Rush founded OceanGate, a company known as OceanGate Expedition. The company's primary goal was to explore the deep seas, reaching depths of 4 to 6 km, using submarines for military, research, and adventure tourism purposes. One of their ambitious objectives was to offer exclusive submarine tours to the wealthiest individuals in the world, allowing them to experience the wonders of the deep seas.

Since its inception, OceanGate has conducted over 200 deep-sea missions using three submarines, all of which have returned safely. Notably, their flagship submarine, Titan, was specifically designed to reach a depth of 4 km. To put this into perspective, the world's tallest building at the time, the Burj Khalifa, is less than a kilometer high, while the base camp of Nanga Parbat stands approximately 4 km above sea level.

One of the most captivating destinations for OceanGate's expeditions is the wreckage of the Titanic. The Titanic, which sank in 1912 during its maiden voyage, remains submerged in international waters around 700 km from the shores of Newfoundland, Canada. Discovered in 1985, the wreckage lies at a depth of approximately 4 km. OceanGate utilized their submarines, including the Titan, to offer wealthy tourists the opportunity to witness the remains of the iconic ship firsthand.

In 2021, OceanGate accomplished a significant feat by successfully reaching the Titanic wreckage for the first time. This was followed by another expedition in 2022, where tourists were safely guided to explore the historic shipwreck. However, on June 18, 2023, tragedy struck as an expedition to showcase the submerged Titanic abruptly ended. The auxiliary boats lost contact with the submarine merely 1 hour and 45 minutes into the trip, leading to worldwide concern and uncertainty regarding the passengers' well-being.

Arthur Luebel, a German tourist who participated in the ill-fated journey, described the submarine as lacking complete safety. Despite encountering technical issues with the battery system during the descent, they managed to reach the Titanic wreckage. Utilizing the limited three-hour window and onboard cameras, they observed the debris before safely returning. The compact submarine accommodated a small group of four to five individuals, with the interior temperature hovering around 4 degrees Celsius.

Titan, OceanGate's specialized submersible, differs from traditional submarines as it can only remain submerged for a few hours. Complete submarines, on the other hand, have the capability to stay underwater for several months. On June 18, 2023, Titan embarked on a journey with five passengers, including Stockton Rush, the owner of OceanGate, British businessman Hamesh Harding, French professional diver Paul Henry, and Shahzada Daud, the Vice President of Angro, a Pakistani company, accompanied by his son.

Descending approximately 4 km into the depths of the sea, where the Titanic wreckage lay, Titan's expedition lasted around 10 to 11 hours. This included the 2 hours and 45 minutes it took to reach the destination, three to four hours spent exploring the wreckage, and the return journey. Delving into the sea exposes the human body to tremendous pressure. For every 10 meters descended, the pressure increases by approximately 1 atmosphere (1 atm). At a depth of 4 km, the pressure is about 400 times greater than that on land.

Tragically, the journey of Titan ended in disaster. After five days of searching with the assistance of boats, robots, and marine drones, part of the wreckage was found a few hundred meters away from the Titanic wreckage. Reports suggest that the submarine may have experienced a breach or fracture, causing water pressure to penetrate the vessel under extreme conditions. This would have occurred within milliseconds, leaving the occupants with no chance of survival.

Following the incident, international organizations and maritime security agencies are emphasizing the need for comprehensive regulations, laws, and certifications to ensure the safety of commercial submarines. The aim is to prevent such tragic incidents from occurring in the future. The extensive search efforts involving teams from the United States, Canada, and France incurred a cost exceeding 6.5 million USD over the course of five days.
