A day after the United States Coast Guard confirmed of the implosion of the disappeared Titan submersible, through which five passengers have been presumed dead, officers are grappling with the additional challenges that lie forward within the advanced investigation of the worldwide catastrophe. The submersible, operated by non-public US agency OceanGate Expeditions, had gone to discover 1912 Titanic wreckage however misplaced contact with the floor after one hour and 45 minutes of its dive off the Canada coast on Sunday.

‘Search for clues about what caused the implosion’

After 5 days of frantic search operation, carried with the assistance of sources shared by 4 nations, rescue groups found a particles subject close to the Titanic wreckage on Thursday night. The particles discovered on the seafloor, 1,600 ft (500 meters) from the bow of the Titanic, indicated that the craft would have suffered a “catastrophic implosion” – a rapid breakup of the submersible, which would have happened within milliseconds, as per experts.

The US Coast Guard said Friday that an official inquiry is yet to be launched into the incident as the agencies are looking for clues as to what caused the vessel to fall apart, which will pave the way for the further investigation.

‘Who has jurisdiction over the case’

The second challenge in the inquiry over the disappearance and implosion of the Titan submersible lies in determining who has the appropriate jurisdiction to lead the investigation as the Titan operated in international waters, the US Coast Guard said. The possibilities include the US Coast Guard, Canadian Coast Guard, a joint effort or involvement of other federal or international agencies.

‘Deep-sea voyages are poorly regulated’

The Titan case involves dealing with murky regulations for deep-sea voyages. The Titan was not registered as a US vessel or with international agencies that regulate safety. It was neither classified by maritime industry groups that set standards on design or construction.

Operating company CEO Stockton Rush, who is among the five dead passengers, didn’t want to be “bogged down by such standards”, information company AP cited his previous stance on the difficulty.

Additionally, the dying waiver signed by the onboard passengers, who paid over ₹2 crore for the trip, is another hurdle in lawsuits. Experts said wrongful death and negligence lawsuits make a case in this incident but legal actions include challenges, including the waivers that warned the passengers of the ways they could die.
