My name is Yong Choi, I am currently a refinery construction QC supervisor. Our company specializes in pipe/vessel welding. Back when I was younger, I was a commercial diver working underwater pipelines and oil/gas platforms. I have personal experience in demolition/installation of underwater pipes and diving equipment although I don't do it anymore. I ran across your video and thought it was interesting and noted that you don't jump to conclusions based on political leanings and biases. which is rare on the internet Back when the pipeline blew up and I saw the footage for the first time, my immediate thought was anchor dragging because this is a fairly common thing that happens. I personally have been on projects due to anchor dragging. Inside the damaged Nord Stream 1 pipeline / ROV-pilot Trond Larsen reacts | Blueye Exclusive - YouTube This link is the most complete version of ROV footage. It's crucial because it has footages before it reaches the pipeline. my interest in this re-sparked due to finding out about this version of the footage, how i ran into your video soon afterwards. if you look at the video, from the start, the drone (size of medium sized trash can). follows a trench up to the pipe. you can clearly see that the trench(which people think where the pipe jumped out of) has clear indication of excavation. it looks like if you dragged a pickaxe across soft mud. givem the size of the drone and camera distance, you can clearly make out that the trench isnt that wide. Certainly not 4FT diameter which the pipeline is sized at if you include the concrete coating. Some people have cited inspection/cleaning pig. i'll just assume you know what these are. Well this can't be true because you arent going to run a pig on a charged line. Pipeline had enough gas to escape for days. No one can "stealthly" run a 48 inch pig with through entire pipeline. That's a LARGE project requiring many personals, heavy equipments on BOTH ends of the pipe. While i never heard of the cathode protection failing causing pipeline of that size/age to burst, I only have minor interactions with them (installing cathodic protection on oil rigs in water). I will try to watch more of your videos to try to understand Also, here is more explanation on why i think anchor dragging was the culprit. its my quora post Koreanese's answer to Who sabotaged Nordstream 1 and 2? Why? - Quora another version of this happened again by ship anchor last year by the way https://www.scmp.com/news/china/diplomacy/article/3274120/china-admits-hong-hong-flagged-ship-destroyed-key-baltic-gas-pipeline-accident?module=perpetual_scroll_0&pgtype=article Yes, of course you can. By the way, have you factored in J-T effect into consideration after the initial rupture of pipe? On Fri, Nov 22, 2024 at 9:26 AM ALEXANDER ROGER I'll also add some diving insight as well. Damaged site is located at ~80meters according to the drone footage. That's about 260ft! That depth is when you require MIXED gas for diving air as well as decompression chamber. You will need commercial sized ships to run that kind of operation. MAX depth for scuba is 40meters ~130ft for a VERY good reason. Unlike 90% of youtube comments they don't know something called "Nitrogen Narcosis". Past 100ft, you start feeling as if you are drunk. Personally, when I went to 160ft, I was so out of my mind that I could not say my name. This is why there is max depth for recreational divers and license is required. Many divers have drowned due to this effect. it becomes more severe the deeper you go, hence why you need a different mixture of gas when you are past 160ft. Regular air is around 78% nitrogen, 1% random inert and 21% oxygen. Mixed gas takes nitrogen out and replaces it with other air such as helium. This way you don't get affected by nitrogen narcosis. This info should help your theory as well.
