More debris of submersible Titan recovered

Marine safety engineers with the Coast Guard’s Marine Board of Investigation (MBI) recovered and transferred remaining debris and evidence of the submersible 'Titan' from the North Atlantic Ocean seafloor on Oct. 4 with the 'Horizon Arctic'. The salvage mission, which was conducted under an existing agreement with U.S. Navy Supervisor of Salvage & Diving, was a follow-up to initial recovery operations following the loss of the submersible. Investigators from the U.S. National Transportation Safety Board (NTSB) and the Transportation Safety Board of Canada joined the salvage expedition as part of their respective safety investigations. The recovered evidence was transferred to a U.S. port for cataloging and analysis. Additional presumed human remains were carefully recovered from within Titan’s debris and transported for analysis by U.S. medical professionals. The MBI was coordinating with NTSB and other international investigative agencies to schedule a joint evidence review of recovered Titan debris. This review session will help determine the next steps for necessary forensic testing.

Canadian ROV found debris of Titan

On June 22 the deep-sea submersible 'Titan' was found in pieces due to a catastrophic implosion, killing the five people aboard the vessel, by the ROPV deployed by the 'Horizon Arctic' hours before. It discovered the wreckage about 1600 feet away from the bow of the 'Titanic'. The 'Titan' had disintegrated into five major fragments, including the boat's tail cone and two sections of the pressure hull. Undersea expert Paul Hankin said: “We found five different major pieces of debris that told us that it was the remains of the Titan. The initial thing we found was the nose cone which was outside of the pressure hull. We then found a large debris field. Within that large debris field we found the front-end bell of the pressure hull. That was the first indication that there was a catastrophic event. Shortly thereafter we found a second smaller debris field. Within that debris field we found the other end of the pressure hull – the aft end bell – which basically comprises the totality of that pressure vessel. We continue to map out the debris field, and as the admiral said, we will do the best we can to fully map out what’s down there.” No sightings of bodies were reported. All five people aboard had died in an instant when the 'Titan' broke up. Their mortal remains may have been taken away by the currents.

Atalante and Horizon Arctic deployed ROVs to search submersible Titan

In the afternoon of June 22, 2023, it has been confirmed that two deepwater ROVs, or remotely operated vehicles, have arrived at the site where the submersible 'Titan'went missing, with one having reached the sea floor. The submersible attached to the Canadian vessel 'Horizon Arctic' has reached the sea floor. The Victor 6000, which is operated from the 'Atalante', has also been deployed. Working in four-hour shifts, a team of two pilots will navigate and control its movement from a control room on board the surface ship. There will also be a third person in the control room helping with the mission. They could be from the Canadian coastguard or from the company which operates the missing submersible. The lights and cameras that Victor 6000 has on board will enable the team on the surface ship to see in real time what is on the floor of the ocean to a distance roughly equivalent to a small tennis court. The French submersible also has two mechanical arms capable of extremely delicate manoeuvres such as cutting or removing debris.
