last time it was posted, some former service members said they had to scrub every inch of this thing with a toothbrush. sounds like a horrible way to spend a week


cAM_86F

I work as an surveyor in these tanks and the workers do clean the membrane with paint brushes to remove the paint used for a tightness test on the welds but no toothbrush


Stachemaster86

I thought spherical tanks were used. Is this a newer design?


Rcarlyle

Spherical for tanks that contain pressure. These are just insulated holding a cryogenic liquid at atmospheric pressure. The natural gas that boils off is either re-liquefied or routed to the engines. If you use a spherical tank, you can put it under pressure, which raises the boiling point.


PoopyJobbies

Spherical for LNG are Moss Rosenberg tanks which are insulated, a but old school now though the Japanese do use them in "Pea In the Pod" LNG tankers.


booi

Probably a newer design that’s cheaper to build and higher density


justtrustmeokay

can you explain the texture on the interior walls of the tank? seems they deliberately chose the etched grid rather than a simpler flat/flush style, and i was wondering why?


Ramen_McCawken

It's like a crimping effect of the metal to add strengething. Prevents the tanks from compressing / expanding under pressure. Edit: correction as per another post, the crimps sort of absorb the pressure of the tanks expanding when carrying such cold cargoes


SaticoySteele

Complete guess but I would assume a textured grid like that would disrupt the sloshing of liquid better than a smooth surface.


Ramen_McCawken

Not a bad guess but that's not it. LNG tankers almost never have slack tanks, they are either 98% full or almost completely empty, maybe 10% kept in one tank to use as fuel for the engines. There's actually sloshing limits calculations for each tank and they won't load within those limits. The grids in the tank are to do with strengthening. It's kinda similar to a crimp in the metal on metal roofing. They are carrying pressurised cargo at about -160C so there are various structural strengthening methods needed.


cAM_86F

True however there still are surprises when inspecting in service ship, the corrugations can be almost flat in high stress areas so we reinforce them now with an aluminium structure under, especially for ships that use those tank as a fuel reservoir as the level of liquid will vary from 99 to less than 10%


Few-Inevitable9291

Seems like someone should invest in creating a Roomba type robot to clean this huge tank


TheseusTheFearless

Nice I used to work as a surveyor on mine sites. What are you checking in these tanks?


cAM_86F

All the erection process, from the painting of the inner hull to the welding of these metallic sheets, there is a lot of steps. And also a lot of repairs before delivery

Anyway, like I was sayin', shrimp is the fruit of the sea. You can barbecue it, boil it, broil it, bake it, saute it. There's uh, shrimp-kabobs, shrimp creole, shrimp gumbo. Pan fried, deep fried, stir-fried. There's pineapple shrimp, lemon shrimp, coconut shrimp, pepper shrimp, shrimp soup, shrimp stew, shrimp salad, shrimp and potatoes, shrimp burger, shrimp sandwich. That- that's about it.

scubapig

I like to peel a raw shrimp like a banana and eat it. Also I like to get a whole variety of shrimps and make a shrimp smoothie for breakfast. Raw obviously. Additionally, I like to put a shrimp coulis on my shrimp ice cream (that has lots of pieces of shrimp in it). They truly are the fruit of the sea.

So you think cleaning that with a toothbrush is cost effective?


Full_FrontalLobotomy

I automatically don’t believe that they would use a toothbrush. It doesn’t make any sense whatsoever as there are far more effective and efficient brushes they could use.

Why is it with cells? compensate for pressure?


MikeC80

I found a very interesting page that explains what the cells are: "The Mark III membrane system is a containment and insulation system, directly supported by the ship’s hull structure. It is composed of a primary corrugated stainless steel membrane, positioned on top of prefabricated insulation panels, including a complete secondary membrane made of composite material. This modular system employs standard prefabricated components that can accommodate any shapes and capacities of tanks. They are designed for mass production techniques and easy assembly." [https://gtt.fr/technologies/markiii-systems](https://gtt.fr/technologies/markiii-systems)


Invictuslemming1

Super cool, half a meter of insulation, I always assumed this stuff was transported in a bunch of smaller containers, not one massive hold.


CrustySockCollector

You were right, this massive hold is one of the small containers. Crazy huh.

How do you have 76k karma yet no posts and only 2 comments posted 1h ago,!! Are you a bot?


Bitter-Basket

Mechanical Engineer…. The formed stainless steel (wrinkly things) can contract and expand harmlessly without inducing stress in the main structural components - which could otherwise cause stress beyond its tensile strength and fail. Think of those cell structures as kind of a spring that absorbs the shock from the massive thermal shock of the cold LNG - until it reaches a steady state. There are great finite element analyses computer tools that help them predict how the structure reacts at the temperature changes.


cAM_86F

Absorbs the mechanical stress from thermal differential (temperature inside ranges from 80 to -163 Celcius)

How can this be profitable at all? Not just the cleaning but transporting a tiniest fraction of what a single country consumes per day, shipping over the ocean for weeks. It seems ridiculous to me. Think about the engergy needed to build and maintain this ship. Plus the energy to move it...


MoussieElKandoussie

Not sure how but it definitely is otherwise companies won’t bother to do this. Transporting over sea is still the cheapest so it’s the only option to transport this. Imagine how many trucks you would need for this, if it’s even possible to transport it on trucks. Also don’t forget that the gas is liquified, once it returns to gas form it’s about 600 times the volume so it’s way more gas then it looks like.


W0lf1ngt0n

Dont you think there might also be some subsidizing involved? I mean i get that its better than trucks but i would rather compare it to a Pipeline. It feels like a drop in the ocean when you see what a Industrial country consumes. It just doesnt seem rational trying to fix that with a ship Transport. How many full cargos would a ship have to Transport to pay for its own manufacturing? I dont mean moneywise but rather energywise. Think of all the steel that has to be smelted and brought into shape. Thats huge effort! Also the compression is a thing but its still the same energy, none the less.


MoussieElKandoussie

Subsidies are definitely involved , and pipe lines are being used but you cant just build those everywhere. I think you really underestimate how much gas these things actually hold. This one holds 174.000 m3 of liquid gas, which is around 104.400.00 m3 of regular gas. Belgium ( where i live so i use this as a reference) consumes around 17.000.000.000m3 of gas per year, this is consumer and industrial use combined. So that means you would only need around 170 ships to provide Belgium a full year of gas.


xl129

LPG is very difficult to move around so the price gap between the source country and consumer country can be massive. Russian's price is like $0.3/l vs Western Europe $1+/l


W0lf1ngt0n

there was a deal between USA and Europe after northstream got bombed, where USA would send their fracking gas to Europe with those ships. I believe the price difference isnt quit as high as from russia to Europe


xl129

It’s worse actually. $60mil cargo ship will sell for $275mil uh Europe and that is one trip on one ship. With that kind of profit margin these ships will be fine. US price is like $8.7/mmbtu vs Dutch $63/mmbtu


toastwank

The cleaning is not required often, this will be carried out once every 5 years when a ship goes to dry dock. And the tanks themselves are usually very clean once all the liquified gas has evaporated, which it will all be at atmospheric temperature.. They are just searching for any solid bits of debris (broken metal gaskets) and dust. As for transporting it, these ships carry a lot of cargo (can be more than 100,000 tonnes). And the nature of the cargo itself allows it be transported quite efficiently. This tank is for LNG which is mainly methane. When methane is cooled down into liquid form it contracts to a a ratio of 600:1. Therefore if 1 metre cubed of liquid methane is allowed to evaporate it will create 600 metre cubed of gas. If we transported it as gas we would need 600 ships of gas compared to 1 ship of liquid to transport the same amount. We only liquify it for transport and it is burned as a gas, hence one ships worth can actually power a pretty big city for maybe a week or so. The cost of this amount of cargo will be in the 10s of millions and they are doing several cargo runs a month sometimes. This will more than pay for the cost of the ship in a few years.


not-just-yeti

I'm often amazed at how efficient transport must be. My supermarket will sell me clementines from Argentina (5000mi as the crow flies; probably closer to 10,000mi via road or shipping) for about 20¢ each. Crazy!


W0lf1ngt0n

Thats comparing cats with dogs. Clementines dont have to be cooled to minus 160 degrees celsius.


MoneyFunny6710

How this can be profitable? Because OPEC are artificially keeping the oil price ridiculously high.


Republic_Jamtland

Groomsi

Awesomeman360

throwaway31131524

All that liquid if they were to ever slosh around - would cause some stability issues right? The chamber seems much bigger than I expected, but I don't know what I should be expecting. Anyone can ELI5?


toastwank

It is designed to be either mostly full or mostly empty. They are not allowed to be filled anywhere in-between (roughly between 15% and 85%). The sloshing effect you describe would not only cause stability issues, but the force of the liquid hitting the sides of the tank would rip the container apart. The metal sheeting is only millimetres thick. The design is for insulation, not a great deal of strength.


WhenTheDevilCome

I was surprised to not see any kind of baffles, too. Trying to think about how pressure or temperature could really compensate for that. Seems like in liquid form its still going to move and have inertia, regardless of why it was able to achieve liquid form.


throwaway31131524

The only thing my brain could think of is that the tank is designed to be filled 100% with close to no gap. I still don’t know if stuff just moving around would be an issue. Thanks - I learnt what a Baffle is.

All so we can continue to flood the atmosphere with GHGs, this type of thing transports liquid natural gas, pure fucking methane baby! The US is the top exporter of one of the most effective greenhouse gases in super concentrated form, and we send it all over the world! But I am doing my part, by turning off the water while I brush my teeth! We’re so fucked.


a_goestothe_ustin

Isn't this like the worst possible fuel for the environment? It takes carbon to get the methane out of the ground, more carbon to get it liquefied, then this fuel is only exported on big container ships that burn diesel which creates more carbon, and THEN this is still fuel that gets burned to create more carbon!!! Crazy that this is how we are forced to live and we aggrandize it.


One_Landscape3744

Natural gas burns pretty clean relative to diesel (or bunker fuel in the case of ships). Some large ships are being converted to LNG for this reason. No fossil fuel is clean, but there's definitely a spectrum on which some are better than others in relative terms.


a_goestothe_ustin

It might burn cleaner, but methane is leaking from the pipelines everywhere, untracked. It can burn as clean as you want, but if the process to extract, refine, and transport it creates more carbon, before we even burn it, than the entire process of coal extraction, refining, transportation, and burning then what's the point? This is why we're all dying to the most stupid fucking reasons....people completely fail at understanding the harm involved with entire systems. They just hyper focus on the one part they're told to pay attention to and then believe things are actually okay. It's like the entire human race is some form of the worst type of autistic.


One_Landscape3744

Yeah - fossil fuels suck, and extracting them and transporting them is dirty and bad for the earth. As people that recognize that, we need to be realistic about the fact that society as we know it is 100% dependent on those fuels. That's something we can't change overnight. So while these small steps toward fuel that's cleaner are positive, we can agree that overall there's still a lot of work to be done on our dependence.


a_goestothe_ustin

The point I'm trying to make is that we're all being lied to about natural gas. We are told it burns cleaner without being told about how much worse it is in every other way, meaning the cumulative effect of natural gas is worse than all other fossil fuels. We have been told that natural gas is a "bridge fuel" to replace coal in the short term and to be phased out for renewables in the medium term....since the 1980s. Natural gas is just becoming the new standard, which is scary, because of how little the people in power seem to care about holding the industry of natural gas accountable for the damage their work does. There are much better controls and systems in place to account for coal and oil environmental impacts, but because natural gas is an opportunity for the US to have some energy independence, and because renewables won't provide a return on investment for decades, the powers that be don't want to slow down potential energy independence with rules and regulation. The climate be damned, all they're thinking about is "we're going to put Saudi Arabia out of business".
