Questions about the Titan's safety were raised in 2018 during a symposium of submersible industry experts and in a lawsuit filed by OceanGate's former head of marine operations, David Lochridge, who claimed he was fired for voicing concerns that the hull could not withstand extreme depths. The robot could also help hook the sub to a surface ship capable of lifting it, the operator said.
The French submersible on its way could be used to help free the Titan if it is stuck on the sea bed, although the robot cannot lift the 21,000-pound (9,525-kg) craft on its own. Titanic expert Tim Maltin said it would be "almost impossible to effect a sub-to-sub rescue" on the seabed. If the Titan is on the ocean floor, a rescue effort would be even more challenging because of the massive pressures and total darkness at a depth of more than 2 miles. It is sealed shut with bolts from the outside, preventing anyone inside from exiting without assistance. If the submersible had managed to return to the surface, it could still be difficult to spot it in the open water, experts said. "It would be a miracle if they are recovered alive," she said.Įven if the Titan were located, retrieving it would present huge logistical challenges. John's Newfoundland.Ī friend of Harding, Jannicke Mikkelsen, who has accompanied the British entrepreneur on other expeditions, told Reuters she was hoping for good news but was not optimistic. "There's still life support available on the submersible, and we'll continue to hold out hope until the very end, Leet, CEO of Miawpukek Horizon Maritime Services, told reporters in St. Sean Leet, who heads a company that jointly owns the support ship, the Polar Prince, told reporters on Wednesday that "all protocols were followed" but declined to give a detailed account of how communication ceased.
But experts say the air supply depends on a range of factors, including whether the submersible still has power and how calm the people aboard have remained.
The Titan set off with 96 hours of air, according to the company, which would mean the oxygen could run out by Thursday morning.
