Wow sounds AMAZING!!! How have I never EVER heard of this fantastic product before!! You’d think something this amazing would have everyone screaming it name from the rooftops but somehow it’s just flow under the radar,,,, wow. I can’t wait to build my online platform,: blog and store yay yay. 🤩 🤩🤩🤩🤩🤩 Now if only someone would sell me a vpn service to keep online hackers from stealing all my money and my precious identity, but alas not such wonder product must exist as one would expect to be hearing about it ALL THE FU?KING TIME!!

[@Armoure10]

​@@noone-ld7pt yeah, its very nice ^^

Agreed, that would a fun one.

[@snyte9685]

Could add a sidenote that another tunnel is about to break that in Norway. The Rogfast tunnel is under construction

[@danielpope6498]

I drove through that once. Didn't know what it was before getting there and was quite surprised how long it went on for

[@ridcully666]

30 years ago i worked on a small tanker. (90 meters long) we travelled up and down the norwegian coast delivering fuel to small fishing harbors. crossing the stad sucked on the best of days. the sea there is really brutal, hope they actually build the tunnel

[@blakethegreatone2058]

It's cool that you have experienced that.

[@JohnCampbell-rn8rz]

50 years ago, I took the ferry from Bergen to Trondheim and remember rounding the Stad well. I especially remember the coastal freighter with decks awash that passed in front of the ferry. I remember because the freighter's captain came out on the bridge and shook his fist at the ferry. You could see the expression on his face, we were that close.

[@mb-3faze]

I wonder if the water level is *exactly* the same on both sides? Tidal height variations and timing could result in significant flow from one side to the other. Still, Norwegian engineers probably have that covered. If not, Simon's disasters-at-the-end-of-the-video section will have some material!

[@aztex6981]

The tunnel is soon complete 😁

Engineers are cool(my fathers one) but imo musicians are the coolest dudes around

[@a1nelson]

⁠@@nolongerblocked6210 I’d estimate that a full 1/3 of the Engineers I’ve worked with have _also_ been musicians, having dual degrees in music, playing clubs on the weekend and the like. (One dude and his band even made it on MTV back in the day, when there was actually music.) Real Engineering requires a very significant amount of creativity as well as an appreciation for and fluent use of patterns. These two groups may be much more alike than different.

[@JessWLStuart]

I would love to see a video on the Lærdan tunnel!

[@QBCPerdition]

I vote for two new videos from this one: 1) The car tunnel you mentioned (but had the wrong label for) 2) A follow-up on the Stad tunnel when it opens, to show how it actually looks and works, as well as updating any problems that may have been encountered.

Driving through southern Louisiana and seeing massive container ships going along at the top of the big hill you are at the bottom of is wild! Not quite the same as a tunnel but a weird feeling to know how far below sea level you are..

[@seniorcajun1]

The "Hills " are called Levees and they were Built by the Corps of Engineers ( U S Army ) to keep the Mississippi River from flooding Louisiana in the Spring time

[@seniorcajun1]

Really in Louisiana , only New Orleans is below Sea level

[@PhilLesh69]

In some places they aren't even man made levees. What he is talking about is actually a thing. You are below sea level in New Orleans and therefore the river's water level is matching the tidal flow at sea level, possibly ten or fifteen feet above you. But the "hill" may be a gradual slope up to water level. It may be natural. Sometimes it might be an imperceptible slope for a mile or two. Yes, along the French quarter you can walk up steps and then look at boats at the level of the top of the steps, and that is a man made earthen levee.

[@seniorcajun1]

@@PhilLesh69 River silt buildup carryed from the river , I thought the Levees stoped that , I never went farther south than New Orleans when I lived in Louisiana

[@brianw612]

This is actually a very straight foreword project. It's very short and many modern bridge projects cost may times more. The ships going through are only 16k tons, medium to large ocean ferry sized. It is an impressive project, but very doable.

[@JackDecker63]

Yes please for video on Laerdal Tunnel!

[@danieloehler2494]

In Weilburg north of Frankfurt(Main) you have three tunnels in a small city: one for ships, one for trains and one for cars.

[@Cruton2025]

A video on another big Norwegian tunnel sounds excellent! Yes please.

[@grundegregersen]

You should do a video about the Rogfast undersea tunnel, it will be 26.6km long and it's deepest point will be 390m below sea-level.

[@pennywise___]

Impressive build time. Here in Australia, it takes us 5 years just to build 2km of two lane road. And usually by the time of completion there are already potholes!

[@andoletube]

And we also blow out the budget by 100% in the process.

[@punk46664]

You must be in one of those efficient states 😂 We've been building the Bruce Hwy for 70 years

[@carlkolthoff5402]

Funny thing is, to us northern Europeans, Norway is known to be a bureaucratic nightmare. Spoke to a guy in Bergen about a road build that had been delayed over and over again for as long as he could remember, and the guy was around 50. The road was just a few km long.

[@SirSilverHair]

​@@carlkolthoff5402You've never been in the real bureaucratic hell that is Germany. Near my parents place they build a 1.7km long and 160m high bridge which took them almost 40 years (Hochmoselbrücke).

[@carlkolthoff5402]

@DennisScheer oh, I've been to Germany many times! It's a lovely country that I thoroughly love to visit. Fortunately, as a tourist I don't really encounter much of the bureaucracy. For the citizens, I imagine it's a whole other story.

[@tabxtra7057]

about 18 km from were the tunnel is planned, is the famous world war 2 raid was done in 1941, (Måløyraidet) Operation Archery , where the British commandos attacked the Germans, One of the British Officers was the famus Jack Churchill who fought in ww2 with longbow, broadsword, and a bagpipe. I think Simon did a video on him.

[@blakethegreatone2058]

This comment is underrated

[@NorwegianSlug]

We do everything in Scandinavia, what’s the problem?

[@robertkohler4173]

The design spec for this tunnel is for smaller feeder cargo ships. The width of the tunnel could handle the old Panama Canal limits, but the depth of water is too shallow for ships of that design.

[@piperjaycie]

r/wooosh 🤣🤣🤣

[@captsirl]

I'm curious to see how they solve the displacement of water. The suction under the hull will be huge. Do you think they will use tractors to pull the ships through the tunnel. I know you could not steer a ship in that situation.

[@robertdragoff6909]

This is on my bucket list when it’s finished…. I’d like to take a ferry ride through the world’s first maritime tunnel…..

[@archerychampion]

Learn how to either hold your breath of use an oxygen tank. The diesel fumes will kil you!

[@u1zha]

​@@archerychampion You serious? How come I never got killed by diesel fumes sitting in a traffic jam in a motorway tunnel?

[@archerychampion]

@@u1zha the diesel fuel used for cargo and most passenger ships is not “clean diesel”. The smoke belched from their stacks is filled with thick black smoke and soot (passengers in aft cabins today complain of the gritty soot that falls on their balconies). The volume of exhaust from one container ship would easily exceed that of a tunnel’s worth of cars. Now picture a stream of ships, one after the other (even if sent through alone). The air would be unbreathable in no time at all.

[@JustNilt]

@@archerychampion Do you think they're unaware of the need for ventilation? This is hardly the first tunnel built by humans, FFS.

[@u1zha]

@@archerychampion "The most efficient container ships are 2x more efficient than typical trains and 20x more efficient than typical trucks" That translates to - no, I think there's no obvious conclusion that the ship fumes would fill the tunnel disproportionately quickly. And this is not a route traveled by very large bulk or container ships, afaiu.

[@bruceshaw5586]

What about lights inside the tunnel and there would also need some sort of traffic regulation like red and green lights on either side of the tunnel if there is only room for one ship to pass at a time.

[@alexdaland]

commercial ships have "ship towers" that works exactly like the towers at airports for planes, telling all ships in the vicinity who goes when. Red and green light, haha. You realize it takes a couple of km stopping a ship, it needs to be planned a while ahead so they can keep moving all the time. And its different for different ship, so there is nowhere to place a red light, even if ships could brake like a car

[@u1zha]

@@alexdaland For airplanes there are lights too on the runway ramps. I would not be surprised if they did put some sort of lights on the tunnel entrances (in addition to the tower you're talking about)

[@Yezpahr]

If ancient Romans had engines then they'd have the first boat tunnel definitely, but they went with canals because there was no way to sail or row a battle ship through a wide/high enough tunnel. They connected Lake Avernus to the ocean and planted a hidden harbor in it, connecting it to another lake and the sea with a series of canals and supply tunnels.

[@abnurtharn2927]

33 deaths in 78 years. But in 2004 the coastal steamer MS Midnatsol experienced engine failure at Stad. In nine meter waves the both engines stopped and the anchors halted the ship 150 meters from the shore, it hit the seabed, but after two hours the crew was able to start the engines again. It had 102 passengers onboard, and if the anchor chains had broken, it is safe to say a lot of the passengers never would have seen daylight again. The sea is a beautiful lover, but a cruel mistress.

[@russellfitzpatrick503]

They do seem to be creating a rod for their own backs by limiting the size of ship to little more than a modern coaster and occasional fishing boats; if you're going to do this then go big (or, at least, bigger).

If a ship isn't capable of guiding itself through that, it probably shouldn't be permitted to move.

One "minor" issue I can see is that thrill seekers with small aircraft will be tempted to fly through the tunnel.

For the time it'll take for ships to come in towards the tunnel, line up, slowly move through it, then navigating around other vessels upon exit, no way they are gonna get 120+ boats through there a day. A container ship size vessel I'll bet is gonna tie things up for at least an hour each. Interesting project nonetheless, I hope they build it!

Remarkable project - like the old Victorian idea of the Caledonian Canal in the Highlands of Scotland but on modern steroids, both cutting through similar landscapes of lochs, fjords and mountainous terrain, both designed to save a risky journey round the stormy northern coasts.

[@timferguson1593]

Simon, how you doin? Why ask if there is something we want to have A farmer took his truck in for repairs. The local mechanics couldn't do it while he waited: so, as he didn't live far, he said he would just walk home. On the way home he stopped at the hardware store and bought a bucket and a gallon of paint. He then stopped by the feed store and picked up a couple of chickens and a goose. However, struggling outside the store he now had a problem. - how to carry his entire purchases home. While he was scratching his head he was approached by a little old lady who told him she was lost. "Can you tell me how to get to 1603 Mockingbird Lane ?" she asked. "Well, “ said the farmer, “as a matter of fact, my farm is very close to that house. I would gladly walk you there, but I can't carry this lot." “Why don't you put the can of paint in the bucket,” suggested the little old lady, “Carry the bucket in one hand, put a chicken under each arm, and carry the goose in your other hand?' “Why, thank you very much,” he said and proceeded to walk the old girl home. On the way he said. “'Let's take my shortcut and go down this alley. We'll be there in no time.” The little old lady looked him over cautiously and then said, “I am a lonely widow without a husband to defend me. How do I know that when we get in the alley you won't hold me up against the wall, pull up my skirt, and have your way with me?” “Holy smokes lady!”, the farmer said. “I'm carrying a bucket, a gallon of paint, two chickens, and a goose. How in the world could I possibly hold you up against the wall and do that?” “Well, if you WERE to do such a thing,” the old lady replied, “you would set the goose down, cover him with the bucket, put the paint on top of the bucket, and I would hold the chickens.” down by you.

This honestly depends on how you classify "full size ship". One could argue a canal boat _is_ a full-size ship for those waterways. In which case this is far from the first. First _cargo ship_ tunnel is more accurate. I'm just being pedantic though, this is such a cool project!

[@PhilLesh69]

There are also huge lifts for boats in canals to join two bodies of water at extremely different elevations. I know that there are a few around germany, and I think there may be one or two around the great lakes as well. I guess the energy to lift a giant tub of water and a boat is same or less than pumping water into a lock to achieve the same.

[@PhilLesh69]

Oh, yeah. There's also canals that have massive boat bridges that pass over other waterways, or roads or railways or even to cross gorges, etc.

Well this is impressive in general. The thing that is most impressive is the initial estimated budget of $100 million US dollars, with additional specs that only increased to $300 million. I don't understand how a project this large could be that cheap? If the issue was not calculating Kroner to US Dollars correctly? That would be silly and embarrassing. Big projects have a tendency to go over budget, but even double seems cheap unless there is some unspecified reason to make it easy?

Would it be easier today to construct a ship-sized sea-level tunnel across the mountain ranges of Panama / Nicaragua / Thailand or a sea-level canal cut? There's conceivably a lot less material to move.

[@MrToradragon]

Panama canal is not sea level cut, but combination of artificial lake, locks, river and canal. And it was cheapest solution and would be even today as lake is only about 28 metres above sea level, roughly half of the height of the tunnel height. In other cases you have proposed, tunnels would have to be at least 40 km long and you would have to build two of them in order to have significant capacity and they would have to be much larger in size and in e.g. in case of Thailand you would be replacing some 2500 km over free sea with 1200 km rout with some 60-80 km long canal section. I am not sure whether that would be wort it. I would say that there is much more potential for ship tunnels and canals, even of this size, around Europe.

[@target844]

@@MrToradragon Panama Canal was initially intended to be at sea level when France tried to build it. There is one large difference between Panama Canal and Stad Ship Tunnel which is the geology. At Stad it is hard gneiss. In Panama, the martial was a lot softer, the Culebra Cut where the removed the most material had the large problem of landslides. If you tried a tunnel in Panama it is very likely the simplest way is to cut and cover, so dig away all material on top build a tube, and then put back material on top. If you try to cross the Kra Isthmus in Thailand the height of the hills is only 75 meters, I assume the location with lowes elevation is most suitable for a canal. There will not be a lot of material on top if large ships should be able to pass so a tunnel is likely not worth it. I Staad the elevation is around 350 meters where the tunnel is, if you move it a bit it is reduced to 200 meters
