An MH370 search team involved in the hunt for the flight that vanished in 2014 has reportedly joined the rescue effort for the Titan submersible.
The search and rescue firm - Phoenix International Deep Ocean Search and Recovery - claims to be " well versed in conducting worldwide underwater projects with a wide range of subsea systems".
They spent a number of years searching for the vanished Malaysian Airlines flight which is believed to have plunged into the sea in 2014 with 239 people on board - however the full wreckage and crash site has never been found.
Phoenix International has now joined a multinational mission to find the missing Titan submersible after its five-man crew lost contact with its mother ship on Sunday, according to German tabloid Bild.
It comes as search teams have reportedly found debris from the missing sub, including claims of a landing frame and rear cover found in a 'debris field'.
Bild claimed one of its reporters 'on site' witnessed a large, newly docked boat from Phoenix International in in St. John's on Newfoundland, Canada.
They said a team of 10 to 12 people wore life jackets bearing the name of the rescue company, and looked like they were ready to set out to sea.
It comes after an expert has said he was told the debris located in the search for the missing OceanGate submersible WAS from the vehicle itself.
Rescue expert and friend of the men trapped on the sub, David Mearns, has told Sky News he received a WhatsApp from someone "directly connected" to the ships involved in the search, who told him "a landing frame and rear cover from the submersible" was recovered.
He said: "There is a WhatsApp group between ourselves and the explorers club, that we have all been connected to as soon as this happened, and our President is directly connected to the ships that are out there, and the message they are telling me 'if you are talking about debris, it was a landing frame and rear cover from the submersible'."
He added: "So again, this is a very unconventional submarine, that rear cover is that pointy end of it, and the landing frame is the little frame that it seems to sit on, and that is how its docked into the landing bit, so that confirms it's the submersible.
The US Coast Guard said experts were “evaluating the information” after a debris field was discovered by a remotely operated vehicle searching for the missing Titan submersible.
A spokesperson for the USCG wrote: "A debris field was discovered within the search area by an ROV near the Titanic.
"Experts within the unified command are evaluating the information."
A conference has been arranged for 3pm EST (8pm UK time) to “discuss the findings”.
The description of a "debris field" is an important use of phrase, Mears added.
He told the broadcaster: "A debris field implies there's a break up of the submersible and at that depth, because we know that they lost communications at around 3,300m… so that really indicates what is the worst case scenario which is a catastrophe failure, an implosion."
