I was privileged to go on board the DSSV Pressure Drop in Nuku’alofa, Tonga, to look around the ship and see the Sub, after Victor Vescovo's successful historic dive to the bottom Tonga's Horizon Deep: June 2019.Awesome team on the Pressure Drop, of scientists, engineers and specialists, who were all friendly professionals that took time to allow us local people tour time and explain in simple layman language how things work. It was such an exciting trip for me, also having the opportunity to see in person the man - Victor Vescovo and his sub that went down to the bottom of our corner of the Pacific ocean.

[@benwesorick]

It's so wild to see how much precaution went into designing and building this incredible vehicle, as well as to see how complex it is inside the chamber. My respect for this team is further increased when you compare it to the inside of the OceanGate Titan sub controlled by a video game controller and quotes from the OceanGate CEO basically saying stuff like safety precautions are for losers and wimps.

[@artxiom]

Yeah, it's almost surreal to watch this after seeing how OceanGate designed and built their sub.

[@illegalduckhunting]

You can not really compare Triton subs who builds commercially successful subs for 16 years to a hobbyist who just wanted to go deep fast no matter the danger. The Titan didn't surpass a single evaluation test other than their "experimental" in-house testing. If the customer doesn't care you don't need to test the sub since it is international waters. Triton 36000/2 on the other hand is one of the most impressive exploration devices since the creation of the Apollo moon lander and it was done by a private company. Price wise you can't compare them either. Triton 36000/2 is in the region of 100-180 million dollars. Titan costs at most not even 10% of that.

[@neilmchardy9061]

50 years ago I was subcontracted to Vickers Oceanics who were at that time building their Pisces mini submarines for oil exploration. When I wee the hull construction on this I am reminded of the care and intensity of manufacturing of the crew sphere of the Pisces. It was made from 50mm boiler plate welded together in pentagons, the welding was continually X-rayed and crack tested. The pressure hull was lowered into deeper and deeper depths to test its integrity and also to add cycles to it. Bearing in mind these were only designed to go to 1800 metres. The hulls were RMS tested to depths of over 25% beyond that. Also there was triple redundancy on all systems just like commercial aircraft. This all being 50 years ago. When I look at the recent developments of the Titan disaster there appears to be nothing other than computer modelling, getting dirty hands and actually destructive testing is 110% imperative but I believe that the Titan farrago was done on the cheap, a Poundland submarine.

[@hashy4940]

What's most important is to make sure the submarine is fully capable to safely go further than it will in reality. In this video you will notice that they put safety first, and mention that they are willing to postpone the diving to make sure it's ready. Stockton, on the other hand, was greedy for money, and thought that using revolutionary materials would buy customers over. It should be pretty obvious that carbon fibre, equivalent to a hard sugar-coated fruit roll, will shatter like glass once it suffers from too much stress. Caladan Oceanic is experienced in the field of deep-sea submarines, OceanGate isnt.

[@Drew791]

I love the similarities and differences between this Triton DSV and James Cameron’s Challenger Deep project; the same basic goal is achieved with different designs, but the same rigorous design and testing processes. It’s cool how Cameron went with a long vertical shaft that held the electronics and instruments with the pressure sphere at the bottom end, but this design team went with a very compact short fat horizontal design that still took advantage of a vertical water column descent. That white and the placement of all the components looks so clean and really uses all the space very efficiently.

[@awKtn32-_-]

It is incredible indeed but generally a white design is frowned upon for submersible vehicles being it’s extremely difficult to spot on the surface in rough weather or underwater. But then again caladan oceanic and victor took all the necessary steps to ensure it would not need to be rescued like and actual gps monitoring and tracking system…..

I just got done watching the Nova documentary on the parbuckling of the Costa Concordia.

I find Victor an amazing human being. His interest in exploring the planet and all of its extremes is simply amazing. And to be brave enough to dive that deep where in one milisecond you can literaly implode from the pressure if something goes wrong. Thank you Victor, you really did make it to where no one ever did and I am glad because you gave everything for that accomplishment 😊

[@silvertongue3003]

Someone who worked on one of these ultra deep scientific subs told me a story once, explaining that the small window becomes almost like a liquid at that pressures, he said you could actually see it move like it’s alive. Can’t remember if it was glass or acrylic windows that he said this happened to, but when I heard this I already decided I’d never go inside one of these things

[@victorvescovo5773]

The windows on this submersible pushed in about 1/4 of an inch at full ocean depth. That was the real trick. How to allow for the flex, *repeatedly*, and not compromise hull integrity. We actually went back and forth on having three viewports versus just one, but Triton argued they could do three and that it would dramatically enhance its scientific value and situational awareness safety. They were 100% right.

[@dblackout1107]

⁠@@victorvescovo5773you the real Victor? If so, your drive is something to really marvel. I’m 28 but hope I can really live for my passions like you someday. And Triton did an outstanding job on this sub. As a mechanical engineer, the design, manufacturing, and pressure testing had my eyes glued. It sounds like while pressured to hit deadlines especially with your money on the line, you didn’t make rash decisions that had you in the sub before it was ready. When you’re on the cutting edge of technology, you’re in new territory that the rulebook might not account for. That doesn’t mean you ignore it. It’s great to see that despite having deadlines, the team evidently crafted an amazingly sturdy craft, and more importantly, validated it as such through testing.

I am watching this incredible video a day after the Titan was found near the Titanic. I am no expert but why in the world did the Titan owners try and re- invent the "wheel". From my understanding this sub is state of the art. Great video.

[@Blueoriontiger]

Humanity will always try to innovate; there's nothing wrong with that. As stated in this video, they wanted to give it a shot with a fully acrylic sphere, which would've been a first for such a deep-diving DSV. What the problem was with Titan was that it was done wrongly. The CEO's view on who gave experience, safety and implementation cost people their lives. As James Cameron said recently, carbon fiber subs were theorized ages ago, but shelved because this testing was done and proved that they weren't reliable/safe.

[@dopecat15]

Stockton Rush cut corners because he didn't want to pay for things to be done properly. He said that he wanted to make big profits so that he could invest that money into more deep sea "innovation".

[@themightypotato3857]

crazy how stockton thought he could just ignore all the immensely complicated and numerously tested engineering. i mean it kind of worked. for a while at least. his crafts went down and up quite a few times. but unfortunately, his project gave in at some point. all of the people on that sub looked like very kind people. hamish struck me personally the most. I never heard about him before, but he just looked like a very kind human being to me. i hope despite (or even because of) this tragedy, it will motivate his son who he was seemingly very close with to embark unto similar (although hopefully safer) adventures. in my mind, all 5 of them were explorers and adventurers. the kind of people with a kind of spirit we desperately need in order to move forward as a civilization. if everyone was a nay-saying and mostly unimportant couch-potato like all the people creating insensitive memes, we wouldn't have gone to space either. we wouldn't even have discovered flight. they lived more exciting lives than most of us ever will and while they might have not discovered much, their misfortune teached everyone who needed it a lesson. and for that they will be remembered forever, just like the titanic. i just wish stockton was slightly less sure of himself. that could have prevented what happened here. while I respect him for the grandiose vision he had (trying to make these deep-sea adventures "accessible" to the public), i don't respect him for how he did it and all the corners he seems to have cut. I, unfortunately, don't think that he will be remembered as he hoped to be remembered. at least not for now. all that said, do not go gentle into that good night. and none of them did. rest in peace & until then.

I haven't read anything about Hamish son, but he will likely inherit Hamish's billionaire status which is mind blowing. 😮 The cost to build Limiting Factor was around $37 million USD, which is chump change to a billionaire. So I'm surprised Hamish didn't just build his own submersible (instead he just paid the $250k to ride in that uncertified trash can called the Titan). Would be cool if Hamish son lived out his father's dream by building a custom submersible, and going deep for his father's legacy 🤔
