As time passes, more and more things that have gone wrong with the ill-fated submersible surfaces - And this is just one of them:

If this is proven to be true, perhaps the submersible would have already imploded (and the occupants crushed) by the immense water pressure down there even long before reaching the depth at which the Titanic rests:

Even if assuming that the submersible remained intact when it reached the seabed floor after losing contact with the surface ship, the remaining oxygen supply onboard would have ran out by now.

May all 5 occupants onboard RIP...

The same person said that OceanGate didn’t do any testing on the hull in their lawsuit. Alongside the 2 inch thinner than expected hull from 7 inch -> 5 inch. This lawsuit was settled out of court.

Lochridge brought up concerns that no non-destructive testing had been performed on the Titan’s hull to check for “delaminations, porosity and voids of sufficient adhesion of the glue being used due to the thickness of the hull,” the suit says. When Lochridge raised the issue, it says, he was told no equipment existed to perform such a test.

The company also gloated that it designed and engineered by the University of washington*… except they said they never did other then testing it in shallow waters.
The filing says OceanGate’s vessel was the result of over eight years of work, including “detailed engineering and development work under a company issued $5 million contract to the University of Washington’s Applied Physics Laboratory.” But according to the University of Washington, the laboratory never dealt with design or engineering for OceanGate’s Titan vessel.

For this sort of thing I would think you need He leak testing. I know about leak testing for semiconductor equipment.

Typical mid pressure connections like NPT or Swagelok compression that can survive 180 bar (2600 psi) without leakage requires He leak rates of ~1e-5 mbar*L/s.

You need to survive 500 bar at 3000 meters. Subsequently I'd assume leak tolerance will be proportionally lower ~1e-6 mbar*L/s.

For semiconductor grade ALD fittings where gas leaks can be dangerous He leak rates are checked to 1e-8 mbar*L/s or better.

A pressurized external leak check on a submersible is not cheap. Even local leak checking without pressure isn't cheap. The actual submersible, looks cheap.

Coastguard has found a debris field within the search area and that it is near the Titanic.


Not officially confirmed but it might as well be confirmed. The US coastguard press briefing occurs on 3:00pm ET and they found the debris a couple hours ago. If the debris wasn’t part of the Titan then I am sure they would have mentioned it by now.

Titan sub debris field: Parts of missing sub's cover found, expert says​

Debris has been found in the search for the missing Titan submersible, reportedly including parts of its outside cover. Dive expert David Mearns told the BBC the president of the Explorers Club - which is connected to the diving community - says the debris includes "a landing frame and a rear cover from the submersible".

All sorts of memes are popping (!) up on Reddit about the sub. It seems the folks over there have no love lost over rich people dying 10k ft underwater.

That shouldn’t be a surprise for obvious reasons tbh.

It's Reddit. They are typically young American Zoomers and Millenials who despise the older generations since they believe that the older generations put them in the current financial mess. Oh and whenever you mention something good about China, they get an aneurysm and start attacking you.

Wait... so tell me, how does an Indian low-cost carrier airline buying large number of A320s even remotely relates to "taking on China for dominance of Asian skies" at all??!

She wrote a new opinion article. “India Global Rupee Ambition”

India taking rupee global to grab piece of dollar trade – ex-central banker​

The Indian rupee’s global ambitions could ease trade settlements with other nations, a former official from the country’s central bank has said.

Asia’s third-largest economy, and one of the world’s fastest growing, is pivoting away from its dollar dependency to ensure its foreign exchange reserves remain stable. Last month, India’s forex reserves edged up to nearly $600 billion, a one-year high.

“India is trying to make the rupee easier to be a currency of transaction and payments with its partners for its own trading needs,” Usha Thorat, a former deputy governor at the Reserve Bank of India (RBI), said in an interview with Bloomberg’s Rishaad Salamat and Haslinda Amin on Thursday. She claimed, however, that “India is not aspiring to make the rupee a reserve currency.”

The use of the rupee as a trade settlement alternative augurs well for countries facing a shortage of the greenback in Asia, Africa and beyond, while a paradigm shift in policy mechanism could shield Indian trade and businesses from exchange risks amid global volatility.

Thorat, who served at the RBI for five years until 2010, also weighed in on India’s global trade prospects, and said its current share of world trade, both exports and imports, is around 7%. “Similarly the share in financial flows is also around the same. It will take a long time for India to get a dominant position in global trade,” she added.

However, earlier this year, M Rajeshwar Rao, a deputy governor of the RBI, insisted that India needed to gear up to manage the inevitable volatility that would emerge in the foreign exchange market as the country progresses further towards internationalization of the rupee.

“It is now widely accepted that while internationalization and a freer capital account comes with its own set of benefits, it is not without risks,” he warned. Rao did not elaborate on how to manage the dangers, but explained that “freer capital flows come with their own set of challenges, the primary one being that of volatility and we need to gear up to manage that.”

Meanwhile, India’s rupee trade settlement mechanism, which was set up by the RBI last July, is attracting several countries. Russia has pivoted towards this payment arrangement following US-led Western sanctions imposed after Moscow launched its military operation in Ukraine.

The de-dollarization bid is a win-win for countries such as sanctions-hit Russia and bankrupt Sri Lanka because it saves conversion expenses and acts as a buffer against foreign exchange rate fluctuations.

So far, 35 nations have expressed interest in better understanding the rupee trade mechanism. The rupee’s bid to become an international currency is likely to reduce India’s growing trade deficit, which stood at $22.12 billion until last month, and also make it stronger in a global market that is facing hyperinflationary headwinds from the West since the Ukraine crisis erupted.

According to the RBI, trade settlement in rupees would reduce dependencies on fully convertible currencies such as the dollar, euro and yen. The Indian rupee’s globalization move could not have been timed better as there has been a significant jump in trade in oil and other

Someone should ask her if Russia is pivoting towards the Rupee system then why is the Ruble-Yuan share significantly higher.

Why are they mad at China doing anything positive or anything that can be positively attributed with it?

Which is all the more hilarious since Reddit is part-owned by Tencent. Inb4 those redditors realise this.
