Missing Titan Submarine: What We know So Far

The US Coast Guard is still trying to identify the source of noises heard by the rescue teams. They called the search so far “inconclusive” and further attempts to detect additional noises have been unsuccessful.

Where is the search taking place?

The Titan is estimated to be roughly 1,500km east and 650km south of Newfoundland. Its depth remains unknown, but the sea in that area is about 3,800 metres deep.

Who is on board?

There are five people on board. Stockton Rush, chief executive of OceanGate Expeditions; Hamish Harding, a British billionaire and owner of Action Aviation; French diving authority Paul-Henry Nargeolet; prominent Pakistani businessman Shahzada Dawood and his son, Suleman.

When is oxygen expected to run out?

The US Coast Guard projects the oxygen in the Titan submersible will run out sometime on Thursday morning. It has a 96-hour supply, which based on its Sunday launch time, would be completely depleted by 7.08am local time (2:08pm EAT time) today. A coastguard spokesman said on Wednesday evening there was fewer than 20 hours of supply remaining.

Who is involved in the search?

The search includes an international assembly of vessels: the French research vessel L’Atalante, equipped with the Victor 6000 robot; the Horizon Arctic, carrying a Flyaway Deep Ocean Salvage System; Canadian coastguard ships CGS John Cabot, CGS Ann Harvey, and CGS Terry Fox; His Majesty’s Canadian Ship Glace Bay, which offers a mobile decompression chamber and medical personnel; and additional support ships including the Polar Prince, Deep Energy, Atlantic Merlin, and Skandi Vinland.

What are the rescue scenarios once found?

Potential rescue options involve either winching it up from the seafloor, which presents substantial challenges due to the extreme depth, or using a flotation device or lift bag to raise the vessel. Both methods would require the use of remotely operated vehicles (ROVs) and face potential obstacles if the sub is entangled in debris. The situation is unprecedented and would require ROV operators to adapt their tactics to the unique challenges.
