Titan submersible, Titanic expedition

[Red-Coat]

I would appreciate if you would post details about the 7 different emergency system on the Titan.

A previous passenger: CBS Sunday Morning correspondent David Pogue, reported this in an interview with NPR's Mary Louise Kelly:

“What you can do is rise to the surface. And there are seven different ways to return to the surface. Just redundancy after redundancy. They can drop sandbags, they can drop lead pipes, they can inflate a balloon, they can use the thrusters. They can even jettison the legs of the sub to lose weight. And some of these, by the way, work even if the power is out and even if everyone on board is passed out. So there's sort of a dead man's switch such that the hooks holding on to sandbags dissolve after a certain number of hours in the water, release the sandbags and bring you to the surface, even if you're unconscious”.

He didn’t mention it, but the submersible also of course has buoyancy tanks that are water-filled to assist descent and air-flushed to assist ascent.

I recall another previous passenger on the vessel (can’t remember his name) describing the emergency procedure for manually releasing the ‘lead pipe’ drop weights, which are apparently made from disused construction pipes. He said that, when all else fails the vessel has to be dramatically tilted to one side and then the other by having the occupants move en masse to each side in turn. The pipes at each side then roll off their supporting cradles in turn when the angle is steep enough.

The pipe-laying ship in attendance (since 20th June) is the “Deep Energy”, operated by TechnipFMC. It has two ROVs and other equipment “suited to the seabed depths in the area”, although when it was first launched it was said that it supports operations at depths up to 3,000 metres. Titanic’s wreck lies at 3,800 metres. A spokesperson from TechnipFMC said: “It is a marine emergency, and we are there at the discretion of the American and Canadian Coast Guard for as long as needed” but didn’t elaborate on what assistance they were capable of providing at seabed depth for the Titanic wreck site.

While I feel bad for those trapped, and even worse for their loved ones, let us not forget they all went into the sub willingly, knowing there was tremendous risk involved. A real shame but a risk they were willing to take. They rolled the dice and it came up craps.

Watched David's interview and he had lots of concerns. They had several problems just trying to get the thing in the water, let alone trying to get to the wreck site.

Thank you for the DETAIL which was what I was looking for. Almost for sure the ROV's would have scanning sonar on them however the cable maybe a little short. Maybe side scan installed as well.

They also said it would float to the top,
Even if they can't make it float.

The ocean is a Big place & The Sub is an Ant swimming in it
even if it come up.
not sure how much air may be left since everything I hear is Not Live.

if the Glass broke or it Implodes My guess all bets are off,
they will ever find it

I do not like the idea that you have to be let out of the sub.
You can't open a hatch to get out someone on the outside has to let you out, that makes it a no go for me.

I think that was probably done to ensure the integrity of the door seal. The lower you go, the higher the pressure, which puts more force around the seal, thereby increasing its efficiency. Logical, but is it possible that it was also inadvisable? My mind intuitively goes to the idea that a user-operated escape mechanism is an absolute necessity for any craft--air, land or sea.

IMO... and after reading / watching details of the equipment /sub / company overall...

This situation was inevitable.

I for one cannot believe that there were not more regulatory entities involved or in place... and i hate to say it... but you would have got to have been sold hook line and sinker to get in that thing... OR in need of some common sense... for the first thing that is OBVIOUS is its size...

Way to small for more than 3 people in my opinion... Backs ups of any real substance would require the size to be at least double that size for a "group" of more than that for safety alone.
Really... when it comes down to it... simply... Its design and size is a joke for any type of realistic "tour ride" type situation... let alone for above basic comfort and safety... it's size also restricted the ability / implementation of realistic redundant safety and survival situations in the event of current situation(s).

We will be hearing about this for some time to come... mostly in the form of lawsuits.

from what the one guy above said they pretty much had to Sign their Lives away before the trip.

The families can sue, but in this world-corporation is separate from personal and it limits the risk of litigation.
Sure the culpa has to be proven even in civil court.
If and when even "if" it was even proven, the judgement would be in the $10s or even $100s millions.
Though it's hard to get blood out of a stone.

I have to agree, but let's hope it doesn't come to that. Any consequential lawsuits would be an interesting situation. It's not completely clear under which country's jurisdiction they would fall, especially since the occupants are of various nationalities and the vessel is operating in international waters.

All passengers are required to sign a disclaimer, which includes a declaration that they are aware the vessel does not have the approval of any recognised regulatory body, but it wouldn't usually be the case that "negligence" can be disclaimed, however carefully the waiver is worded. Not sure about other countries but, under UK/EU law, disclaimers and "small print" are invalid in Contract Law if the terms and conditions are unreasonable to the extent that they are inherently "unfair"... even if they have been agreed to.

It's not looking good, but never lose hope.

 

[ARC]

Sorry to say this... and i have refrained from saying this up to this point.
Realistically... and very unfortunately... due to sub design and circumstances there was / is not enough time to perform any type of realistic rescue mission at these depths.
This would have had to be begun almost immediately after loss of contact.
The posture of many of those involved is and has been more of a recovery mission than a rescue mission.
Even if located there is little that can / could be done in time if the #'s are indeed correct.

Sad to say... but this is the reality.

This sub's "safety nets" fell way short of realistic proportions.
Bad design.
Bad implementation.
Bad Decisions.
Bad... period.

I hope and pray that a miracle happens.

Debris field found in Titanic search area, U.S. Coast Guard says​

"A debris field was found in the search area for the missing Titan submersible by a remotely-operated-vehicle near the Titanic, the United States Coast Guard tweeted at 11:48 a.m. on Thursday, June 22."

The debris field was found near the Titanic ship in the search area for the missing submersible.

Well it seems the best case scenario at this time is they did get to see the Titanic in its present state. We might never know that, as dead men tell no tales.

 

[jeff of pa]

the search area is supposedly the size of Connecticut.
so that's a large area. there may be all kinds of Debris from all kinds of sources possible. including Drones.

Word is they are out of air even if the debris wasn't from them,

 

[Red-Coat]

Just reported. The 'debris field' contains pieces identified as the landing frame and rear hatch cover of the missing submersible.

Very sad.

The debree field is very close to the Titanic, that is a well mapped and very photographed area.
