The recent disappearance of the Titan, a deep-sea faring submersible vessel, during an expedition to the Titanic wreckage site has raised concerns about the safety and emergency options available to the crew. With limited oxygen supply and the search efforts so far unsuccessful, it is crucial to explore the potential emergency measures the vessel may have had to resurface and save the passengers on board.

The Titan utilized two communication systems to maintain contact with its surface ship. However, both systems ceased to function approximately one hour and 45 minutes after the submersible submerged. The sudden loss of communication raises questions about potential power failure or a catastrophic hull breach leading to instant implosion.

While the exact cause remains unknown, experts have also speculated the possibility of a leak in the Titan’s pressure hull.

Emergency Measures for Resurfacing:

Drop Weights: The Titan was equipped with seven onboard backup systems, including drop weights consisting of sandbags and lead pipes. In an emergency, these weights would detach and create buoyancy, allowing the vessel to ascend to the surface.

Inflatable Balloon: The submersible was also outfitted with an inflatable balloon designed to facilitate resurfacing. Even if the crew became incapacitated, this mechanism could automatically initiate the vessel’s ascent.

In the event of a power or communication failure, the submersible could have resurfaced and remained afloat until it was found. The Titan’s buoyancy would have allowed it to float on the surface, potentially aiding search and rescue efforts.

Search and Rescue Possibilities:

OceanGate Expeditions and officials are actively seeking an unmanned vehicle capable of reaching the depth of 4,000 meters where the Titan may be located. One such option is the US Navy’s Curv-21, which can operate at depths of up to 20,000 feet. Equipped with video, navigation, and sonar capabilities, it could assist in locating and potentially rescuing the crew.

French President Emmanuel Macron has dispatched the research ship Atlante, equipped with an underwater robot capable of reaching depths of 4,000 meters. This vessel’s arrival at the site aims to bolster search and rescue efforts.

While the situation remains dire, history offers a glimmer of hope. In 1973, two British sailors were rescued from a depth of 487 meters after becoming stranded in a steel ball. Despite having only 12 minutes of oxygen remaining, they were successfully retrieved, demonstrating the possibility of saving the crew of the Titan if it is found.
