Sonar devices have detected repeated sounds every 30 seconds in the search for the missing Titan submersible, but the source remains undetermined, possibly due to interference from the Titanic's metallic structure. The sub's communication was lost before it reached the Titanic, and it relies on its mothership for recovery, which complicates the search. Concerns were raised about the potential effects of the sub on marine life and the feasibility of using trained dolphins for detection, although their diving limits pose challenges. Recent reports suggest that the sub may have imploded during descent, which could have generated detectable sound waves, but no recordings were made at the time. The tragic incident highlights the risks associated with deep-sea tourism and the need for stringent safety regulations.

See the EDIT below.

Could you verify/correct that youtube link?

youtube does not recognize that link, a youtube search shows "not found."
Google returns something in Russian.
:oldcry:

[EDIT] It showed up in this post as a playing image; yet your post (and all previous youtube links) shows up as a white triangle inside a Red rectangle!

[EDIT 2] Now, this post is back to White triangle inside Red rectangle.

I suspect the poldergeists & gremlins are playing with us!

[EDIT 3] Arrrgh! A screen refresh turns youtube links back to the triangle/rectangle. I think I'll give up trying to understand it. :cry:
NBC may be better.

Scott Manley plans to cover the information gleaned from the hearings. Here's a recent video of his.

Scott Manely released a new video on the subject today (29-09-2024).

Water from previous dives was pushed into voids in the carbon fiber at near 6,000 psi.
Titan was often stored outside in freezing conditions.
The water in the voids expanded with the force near 30,000 psi as it froze into ice.

The 3500 pound "door" was hung on a hinge with less than 10 inches separating the hinge points on each end of the hinge.
Multi-thousand pound doors on bank safes often have the hinge points more than 6 feet apart.

Titan submersible imploded due to poor engineering

Hull Failure and Implosion of Submersible Titan
https://www.ntsb.gov/investigations/Pages/DCA23FM036.aspx
We found that the Titan pressure vessel likely sustained damage after it surfaced at the end of dive 80 in the form of one or more delaminations, which weakened the pressure vessel. We found that after dive 82, the Titan sustained additional damage (of unknown origin) that further deteriorated and weakened the pressure vessel. The existing delaminations and additional damage that deteriorated the condition of the pressure vessel between dive 82 and the casualty dive (dive 88) resulted in a local buckling failure that led to the implosion of the Titan.

We found that OceanGate’s engineering process for the Titan was inadequate and resulted in the construction of a carbon fiber composite pressure vessel that contained multiple anomalies and failed to meet necessary strength and durability requirements. Because OceanGate did not adequately test the Titan, the company was unaware of the pressure vessel’s actual strength and durability, which was likely much lower than their target, as well as the implications of how certain operational changes, including storage condition and towing, could impact the integrity of the pressure vessel and overall safety of the vessel. Additionally, OceanGate’s analysis of Titan pressure vessel real-time monitoring data was flawed, so the company was unaware that the Titan was damaged and needed to be immediately removed from service after dive 80.

We found that, had OceanGate followed Navigation and Vessel Inspection Circular (NVIC) 05-93 guidance for emergency response plans, they likely would have had emergency response assets standing by, and the Titan likely would have been found sooner, saving time and resources even though a rescue was not possible in this case. Despite OceanGate’s failure to notify search and rescue assets about its planned expedition, as well as the limited resources able to operate at the depth of the Titanic, the US Coast Guard’s search and rescue coordination efforts were effective and resulted in the timely discovery of the Titan wreckage.

It appears to be criminal negligence.
