The missing submarine “Titan” runs out of oxygen: what is known about the search
[ad_1]
The search for the submarine with tourists “Titan”, which started an expedition to the sunken liner “Titanic” and disappeared on June 18, is at a critical stage. The ship has oxygen reserves for 96 hours, that is, 4 days, reports CNN. On June 21, the US Coast Guard, which is engaged in the search for the tourist boat, expanded the area of operation and redirected some of the equipment to other areas. Rescuers want to determine the place of origin of the underwater thump, which was recorded by Canadian planes. The sounds sounded at 30-minute intervals. Titanium.

The international fleet and the fleet of US and Canadian ships with highly specialized equipment and technical experts were involved in the search. Ocean researcher and ocean operations and engineering consultant Tom Detweiler, who led the expedition that discovered the wreckage of the Titanic in 1985, called it a “huge effort” to move the necessary heavy equipment to the search site. “The equipment is very, very large, so it had to be brought in by cargo planes. It was done as quickly as possible,” he added. Detweiler added that once the submersible is found at depth, it will take some time to bring it to the surface. It will take about two hours. “At this depth, it is impossible to let oxygen into the submarine. It will be necessary to raise it as soon as possible, open the hatch and get the people,” he said.

However, in the absence of communication, finding an underwater vehicle the size of a van in the vast Atlantic would prove difficult. The exit from the boat is carefully closed, which makes it impossible to rescue tourists without outside help, even if it floats. If the Titan is stuck on the ocean floor, rescue operations can be complicated by extreme hydrostatic pressure and complete darkness at the bottom of the sea. It will be recalled that the submarine “Titan” of the American company OceanGate Expeditions lost contact with its surface vessel on the morning of June 18, approximately 1 hour 45 minutes after the dive. The excursion to the Titanic wreckage was supposed to last 2 hours. The mini-submarine is designed to stay underwater for 96 hours. However, on the morning of June 21, the boat had to run out of oxygen. So even if the boat survived, the tourists who were on it most likely died, says expert Tim Matlin. On June 20, one of the five Titan passengers, Irish researcher Rory Golden, got in touch and said he was fine. In his appeal, the man asked the dispatcher not to try to guess the names of other passengers, because it is unethical. British billionaire Hamish Harding, 58, and Pakistani-born businessman Shahzada Dawood, 48, and their 19-year-old son Suleman, both of whom are citizens of Great Britain. French explorer Paul-Henri Narjolet, 77, and Stockton Rush, founder and CEO of OceanGate Expeditions, were also reportedly on board. Authorities have not confirmed the identities of any passengers. As of June 19, aircraft and ships from the US Coast Guard, US Navy and Canadian Armed Forces have combed more than 7,600 square miles of the North Atlantic.
