The American Coast Guard released the first photo from the intensive investigations search for the Titan submarine which was lost in the Atlantic with five passengers. The rescue boat can be seen in the photo Deep Energy – one of the last hopes for saving the five passengers. Oxygen supplies on Titan appear to have now been depleted to just 24 hours, with teams of rescuers racing to save the five.

Deep Energy carries two remotely operated vehicles (ROVs), which can dive to a depth of 3,000 meters. The wreck of the Titanic is located at a depth of 3,800 meters.

At the same time, the US Coast Guard announced that three boats arrived in the investigation area on Wednesday morning, the The John Cabot, the Skandi Vinland and the Atlantic Merlin.

French aid

The ship Atalante sent by the French Institute of Marine Research to enhance investigations, carries a manned submarine called Nautile and a remote-controlled robotknown as the Victor 6000.

The Nautilus it can to dive to a depth of 6,000 meters with a crew of three and is one of the few manned deep sea submarines. It has three wide-angle viewing windows and LED headlights that provide a direct view of the seabed. A dive of this particular submarine can last up to eight hours, six of which can be spent working on the seabed.

The robot Vector 6000, which it should descend to a depth of about 4,000 meterstrying to make use of the built-in tracking equipment it has, it is designed to operate at a depth of up to 6 km. The robot is connected to Atalante via an 8,000 meter long electromechanical cable. The French robot has remote-controlled arms with which it can cut cables or perform other maneuvers to free a stuck vessel. It can also dive deeper than any other equipment currently at the wreck site in the North Atlantic.

According to forecasts, Atlante is expected to be on site by 8pm. Paris time (9 Greek time), Le Figaro reported.

Optimism

At the same time, Australian submarine search and rescue expert Frank Owentold the BBC that “his confidence (that they might find the submarine) skyrocketed” when he heard that floating sound probes “caught” knocking noises through the sea.

“There are two reasons for this,” he explains. “First, a retired French navy diver is on board (73-year-old French explorer Paul Henri Narzolet, director of underwater research at the company that owns the rights to the Titanic wreck). He of course he will know the protocol to try to alert the search forces … of the strikes every half hour.”

According with the magazine Rolling Stone, a Canadian P-8 planewho participates in the investigations, “heard knocking noises in that area every 30 minutes. “Four hours later an additional sonar sounding system was deployed and the hits were still being heard.”

Using multiple sound-tracking sonar could give a relative clue of their location and limit the area of ​​investigations.

As the search continues, in the latest development, a Canadian warship equipped with a six-person hyperbaric recompression chamber and a team specializing in diving medicine is expected to arrive in the area soon.
