    I work for a company that makes similar undersea cables off and on for random customers (we make custom wire/cable as a business). The extrusion machines for the final jacket on the undersea stuff is massive. The extruder screw takes 6 guys and a special cart to install. looking at all those sub components... makes me shudder knowing how easy it is to screw up one production stage and completely ruin all the stages prior... Lol, makes me glad I work primary extrusion (the stages that put the first layer of insulation on bare metal strand) and don't generally have to worry about my mistakes, if any, ruining everyone else's work. Final Jacket on a cable like this probably has multiple process techs/engineers triple checking everything, so the operators probably aren't the ones to get in trouble if something goes wrong (the buck stops at the tech), but still... All those stages... So many single points of failure.

      @@toddpacker7058 I will admit the extruders we use are actually quite old but the reason we stick with them is because newer automated extruders don't allow the amount of flexibility you need to make custom wire on the fly. The kind of cables and wires we make often require extremely specific customizations that would be extremely difficult to do on fully automated machines owing to the fact that automated machines usually require custom tooling for every single job.

      @@qurkatimilaz3787 they have steel for armoring against tight bending and friction from the seafloor. The isolation is extra-wide as the voltage is pretty high. There's a "semiconductor" layer (not like silicon, in this case it means not very conductive) to control electric fields and prevent arcing. Often there's also glass fiber for communication, fillers to get a round even profile and other plastics for stabilization.
      The steel armoring also prevents excessive stretching of the cable when laying it down and when moved by the seafloor. Copper and plastics are too soft to carry the weight of the cable itself. Transmission lines also use steel-core aluminium wire to prevent tearing it apart.

      The higher the voltage the lower the current for the same power.
      So, long distance high voltage lines has established at 400.000volt (400kV).
      As you imagine in such high voltage, the insulation of a cable inside salty water should be extremely robust.
      Additionally to that, the cable have added several layers, metallic and polymer, to protect from wear.

    Back in the 1980's a company I worked for made two custom platinum wire temperature sensors used on a Japanese cable laying ship. It seems that they would measure ocean floor temperature and opt for colder temperatures for the cable if they could. And the "weather" on the ocean floor changed so slowly that it was nearly constant for their purposes. These sensors were on 25,000 foot cables we had custom made. 4 wires and a central stranded steel wire for strength. The cable was only about 1/2 inch diameter. The extra strength was needed because the weight of the cable itself, if just a normal cable, would tear it apart. Electronics types will know right away why there were four wires. Two to provide a current through the platinum wire, and two wires to sense the voltage across it with as little load as possible.

      There are reasons to why you think you see curvature in an airplane is because the windows in an airplane are not flat so it makes a fisheye effect just like a gopro fisheye lens. That's why divers use goggles with flat glass because it doesn't distort. An other reason is because you see the same distance 360 degrees around you, i.e. you see a circle, so that also can make you think that the horizon created by the limit of your vision is curvature.

I'm sure the customer has some reason for it, but nobody I've been able to ask has the slightest guess. It doesn't provide shielding, the metal has to be contiguous which a powder isn't. It can't be used as a drain (grounding) because the breakdown voltage of the plastic in between the particles is too high, but it's too low to provide reasonable insulation against spurious high voltage. It doesn't even get a second layer of some other metal free plastic before we ship it, so I assume they are using it as is. The ability to add any additional layers would mean they wouldn't need us to put on the platinum plastic layer first.
      So yeah I have no idea why they do it.

    TY for sharing. There might be cables that supply offshore oil and gas platforms electricity in other parts of the World. However, while working out in the Gulf of Mexico’s Oil Patch as an OSV Captain, I never saw any offshore platforms that utilized cables to supply their electricity. Most of the newer platforms utilized their field’s own natural gas to run their generators, while many of the older platforms utilized diesel fuel which our vessels pumped to their storage tanks located on the platform. On a similar note, I witnessed offshore oil and gas pipelines being installed by the M/V Lorelei; a pipe laying ship, which was fascinating. Also, while working as a US Park Ranger, I also observed an old AT&T telephone cable, that was no longer being used, which ran underneath Lake Mohave from the Arizona side to the Nevada side of Lake Mead’s National Recreation Area. That was a fascinating story about how that happened too. 😉

As I vaguely explained earlier, in 2000, I worked as a Captain on the M/V Gary John; a mini-supply, for Gilbert Charmie Marine which was bought out by Seacor Marine based out of Houma, LA. Let me add some additional info which I did not elaborate on in my earlier comments about the Hoover Diana which might have been confusing. At that time, we were working as a Field Boat for Exxon Mobile’s “Hoover Diana” project; or Diana Hoover as some people call it, which was the World’s largest (DDCV) Deep Draft Caisson Vessel. Also, at that time, i believe that it was the deepest deep water oil and gas platform in the World too. The Hoover Field is located 125km south of Freeport, TX in 4,800 ft of water. Normally you can only see around 6km out at sea because of the curvature of the earth. The Hoover Diana platform was visible at least 12-14km away. The flare boom was massive besides the platform, and when flaring excess pressure off of the wells, it was as though, a giant heat lamp was turned on above the platform, especially at night. The flame shot up for at least 300 feet, and you could actually feel the heat if you were standing on the upper deck, outside of the wheelhouse. I was fortunate to crew change off of the platform on Exxon Mobile’s Sikorsky S-76 Corporate Helicopter en-route to Galveston, TX which was really something. The S-76 flew at around 178mph. That whole experience was an unforgettable one, plus the deep sea fishing was really great too catching Mahi-Mahi on flying fish. I was so fortunate to work at the platform when it was brand new. That’s also where I got to see the deep sea pipe laying ship; called the Lorelei, working on the job, around the clock for a couple of months. 😉

Then before any splitting can really begin, you'd need to remove any galvanized steel reinforcement, otherwise there's no real way you're cutting into that in any efficient manner.
      I suspect mostly, that the cost of recovering is just pulling it out of the water- not sure how much force it would take, but those cables look like they might be tens of ton of weight to pull one up - and if you can pull it up, where are you going to store it? Will you cut it at some point, dive, and try to pick it up again, or pull the whole thing up in one go?
      I'm not saying it's impossible for just an average person to do, but if you feel like you're capable of doing that on the kind of budget and resources that an average person has access to, then you likely shouldn't stay an average person, and should seek employment doing something extraordinary.

      You are right that would have been interesting to see. Incidentally when the first transatlantic cable was laid, half of it was contained in two ships that started laying from the middle of Atlantic going to opposite directions. So you can fit an enormous amount of cable in single vessel. Not sure if it was spooled at all back then. But certainly they made several splices, one at the middle of the Atlantic and at least once the cable broke, they fished it up, repaired it and continued.

      海底ケーブルは戦争の趨勢に大きく関わっている。
      なぜか教科書や戦史では触れられないが、看過できない事実だと思っている。
      1900年前後に、商用発電の普及やガソリン自動車の登場を受け、電線の絶縁被膜やタイヤ用途に天然ゴムの需要が激増した。また、1860年代からモールス方式の電信も普及し、海底ケーブルの需要が高まりつつあった。
      既に天然ゴムが採れる中南米や東南アジアは欧州各国の植民地だったが、その中でもマレーからソロモン諸島にかけて生えていたガタパーチャという種が海底での腐食を防ぐ特性が高いことが判明。この地を支配していたイギリスがガタパーチャを独占した結果、イギリスは1902年に世界一周する海底ケーブル網を完成させ、各国の通信事業者に貸し出すようになった。つまり、第一次大戦の頃には、イギリスは世界中の通信を傍受できる体制になっていたということ。大英帝国の強さの秘訣は常に「通信の支配」だったと俺は思っている。
      このことに気付いた各国は、WW1以降通信傍受のリスクを避けるために、無線通信の技術向上に力を注ぎ、様々な技術が急速に進歩した。
      ちなみに、この時点でイギリスからの借用では無い独自の海底ケーブルを敷設していたのは日本のみ。
