Please take extra care when climbing into void spaces that haven’t been ventilated, they can be very dangerous places. Take necessary precautions - never enter without someone else looking out for you, and I’d recommend you also take an emergency air breathing set with you too.
He's covered breathing gear that was kept on the ship before, I believe he's aware. That said, don't take it, use it. By the time you realize you're being overcome it'll be too late to futz with strapping a mask on.
They have stated in previous videos that they keep places like these ventilated continuously so I don't think they classify as stale air containers anymore
I also expect they thoroughly checked these areas before he climbed into them
Full respect for crawling about in there . These spaces can be very claustrophobic and filthy . Certainly the internal surfaces look very good and as Ryan mentioned that has to be down to the quality of the last maintenance work . Remembering the film of the last docking hopefully a similar job was done on the visible areas of corrosion outside which might make things more straight forward when she docks down .
Well this now explains the Dramatic damage on other ships that occurred in collisions or Severe weather, as it turns out the bows are relatively a Tin Can as a crumple zone and weight save
I certainly hope you adhere to a strict confined space entry procedure: pre-entry air testing, ventilation, emergency air supply, incapacitation evacuation plan, instant communication with rescue, etc. We would not want to lose you in a confined space ... 🙂
They've mentioned in previous videos where they were looking at confined spaces that since they're no longer an active duty vessel. These places aren't kept watertight anymore and are essentially covered just by a mesh and then are continuously ventilated anyway as well as preventilated before anybody ever goes into them. Also, he does have his camera person with him and I'm sure there was a rescue breathing set off camera somewhere. Ryan might look like he's traveling into tight spaces all gung ho on camera but he's been at this for long enough. I'm sure he has everything he needs
I was just thinking that myself...
@@Its-Just-Zip I hope...
I keep wanting to see Draeger test tubes and hear a red devil blower putting fresh air into those tanks. We had a shipmate get injured back in the 80's.
What happen to him?
Man, you just gave me flashbacks
On my sub, our A Gangers were trying to isolate an oxygen leak and were using nitrogen to purge the system. One of the guys entered the space and took a nap not knowing it was oxygen deficient. He suffered brain damage as a result. @@studinthemaking
They test for air quality and have procedures for confined spaces.
@@scubasky yes. I'm saying I was getting flashbacks from my time in the Navy, using said equipment.
I live just east of Baton Rouge, and have toured the Kidd a few times, I've always thought how cool it would be to crawl around and explore all the nooks and crannies. These vids allow me to do it vicariously through you (even though the Kidd is a destroyer not a battleship). Thanks for that chance Ryan.
You can volunteer and do all the bilge crawling you want. It’s super important work, so you’d be really helping the museum out.
Keep in mind that these spaces like every other space on the USS Kidd are much smaller than even on a cruiser. I ahve toured the USS Kidd I either missed it or it was not open, but I wanted to see the engine room.
You know when Ryan has on the headlamp fun is to ensue! 😊😊😊
I would not be in there without gloves, knee and elbow pads. Man that ship structure is crazy!
Wartime efficiency assumes the people doing the work and serving aboard her are tough and not in a position to complain.
You spoke about the sound of dripping water down inside a ship, several years ago,my wife and I were given free access of the carferry SS City of
Milwaukee. We were down in the engine room and boiler room, we could hear a drip of water somewhere down there. We eventually located the dripping in a sink in the flicker. Very spooky sound within a ship!
Sometimes just the sound of the water hitting the hull can make that sound especially if another boat goes by and creates a wake while you're tied to the dock. It's a sound you just get used to over time.
I spent the night on the SS City of Milwaukee a few weeks ago and took the tour. I could look down into the bilge through grating around the propeller shaft thrust bearings and see some water. Hope they have working bilge pumps!
Had a great time spending the night on it. Stayed in the 1st Engineer’s stateroom
@@matth5309 believe it or not it's very normal thing to have some water in the bilge you just don't want to let it get to a level where it becomes detrimental. I worked as a commercial fisherman and we would always get a bit of water in the bilge from washing off the deck etc and right down to the packing gland seal itself. if you watch some of Ryan's other videos he states that it was a common and normal thing for the packing glands to leak every so often but it was mitigated by regular inspections and tightening of the glands themselves that prevented more water from entering the ship.
I’m so happy that this beautiful Battleship got funding to go onto dry dock, she deserves it.
She still needs a lot more.
You can call it the pointy end, we won't mind
Always a pleasure when Ryan explores the depths of the ship!
I live in Ontario Canada and actually spent an overnight on either uss Little Rock or the Sullivans, as a Boy Scout. To long ago to remember which ship but toured both as well as the submarine at that location. It is a memory I will never forget. 42 years old now and still remember being in awe. My grandfather also served during Korea on Gm s Haida. Another museum ship worth visiting here in Hamilton Ontario.
I worry about my old 1948, Chris Craft's Cruiser' water line always. As the old saying goes, "they sail their waterlines off" doesn't matter what they are made of. Really love your channel and hope to visit.
I'm always trying to explain to people about how you crawl into obscure spaces on the ship, and they ask why. I say I believe that's the curator's job to inspect everywhere! Also, they get a kick out of the deck pieces from the ship I ordered. Keep the videos coming!
Congrats Libby and Crew. You really put Ryan in a tight spot. Excellent video and educational.
Literally😂😂
Keeping my fingers crossed for no leaks. Thank you Ryan for sharing.
The Perry frigates were belted at the waterline in the 1990's. Because of waterline corrosion, can you over plate at the new waterline while in drydock. Over the product we used at sima mayport was belzona it's a two part epoxy that seals and makes layer similar to porcelain.
This brings back memories as a young man of having the job of hand painting inside peaks and voids to prevent rust. We didn’t have supplied air then so we basically painted in the confined space until we got to dizzy from the paint fumes and then came out for some fresh air. Repeat that process until the job is finished.
I think it a great reason to stay up for 2:17 more hours. It will be 01:00 am but guess what Ryan, thats the only thing I can do from here to support :)
Ryan, what about using ultrasound non-destructive testing (US-NDT) to evaluate the thickness of the steel plate in this type of area of the ship? Water is a great conductor of ultrasound (ask a submariner if you wish), so you should be able to see reflections from the outside surface of the steel plate that can be analyzed to determine steel thickness. A testing program could help avoid "surprises" that would give a ship curator nightmares about dripping or flooding water below the waterline.
I don’t know as much about battleships as Ryan, but I know a lot about vessels as whole. Those holes you see cut in those bulkheads might be for weight saving but they’re also acting %100 as tank baffles. When those tanks flood, those holes act as baffles so you don’t get free service effect in your tanks and have sloshing liquid which In turn would make a major stability problem even on a ship as big as NJ.
Ryan, what about bringing the original peak tank hull skin down to white metal treating it and overplating it with a sacrificial skin? Especially at the wind/water line? Or perhaps totally replace that skin with a more appropriate steel for a museum ship that may be a long time between drydockings.
I'm sure Ryan would agree that construction / Drydock time and associated costs prohibit such extreme measures.
@@the_lost_navigator More than likely but if the ship is really bad in that area or better off in others, some priorities could possibly be shifted.
Watching Ryan crawl around the inners of the New Jersey fills me with confidence that he is the right guy to take care of her. I just hope that the other curators of our entire museum fleet are as diligent. I have been watching the Texas' drydocking repairs with great interest since she is the grandma of the fleet. We have learned alot about what not to do by the exsprences from Texas. So glad she was saved. Hopefully New Jersey and her sisters will never get as bad as she was. I am a North Carolinian so BB-55 is my Favorite have visited a couple of times and saw the Missouri while vacationing in Hawaii. Time and money don't permit seeing them all.
drip drip drip isnt so bad, its when it sounds like niagra falls that your sphincter tightens up.
😂
Add up over time
So wise , Thank You . A fine example of the importance of preventative maitanance
Wow...
Deep inside the ship.
Bad time for the batteries to the lights to run out!!!!
Donated! Thank you for what you do!
(Feel much better donating $50 than on an over-priced meal here in CA)
I have 45 little souls to care for over the next 9 months, and I feel for you. Worrying about the future of our charges is never easy. I'll also never understand why Missouri wasn't returned to Bremerton. It was about the best choice for a saltwater port to hold a Museum ship and allow it to be preserved with fewer (and a shorter) trips to drydock.
One last thought. For all of the patriotic chest-thumping that U.S. corporations do, I'd think that at least one would sponsor solid ballast to be loaded aboard to bring the lady into trim so she can clear the bridge without needing to flood internal spaces and risking hull damage as a result.
These same "patriotic" corporations (particularly sports teams) charge the US military for the widely publicized tear-jerker reunions of service members with their families.
Perhaps a USA based steel mill would be willing to donate some plate metal toward reinforcing BB62 during her drydock period...
Maybe a few truckloads of steel plating... Maybe just selling more of the steel at wholesale/production cost... Either way could be a savings.
Worth looking into. (starting months early)
Solid ballast isn't a good choice because it doesn't load the ship evenly, and will introduce other stresses on the hull that can cause hogging. Not to mention the extreme amount of labor involved in moving what would need to be thousands of tons of lead bricks a handful at a time down 6 decks of vertical ladders. That's why it's not an option. Nobody in Bremerton was able to put together a viable business plan for a Missouri museum. Bremerton is a poor location for a ship museum because it's not a tourist town and there's little other reason to go there. The only people who would go there have to be highly motivated to see the ship, and most will only make that trip once. There's only one pier in Bremerton where Missouri would fit, and it's in an active naval shipyard where access and room to build permanent visitor facilities is very limited. In Pearl Harbor, Missouri is next door to Hawaii's #1 tourist attraction and gets paid visits from, and sells souvenirs to, lots of people who would never make a trip to Bremerton to see her. Visitation there is huge compared to the trickle of people who used to visit in Bremerton when Missouri was in reserve there. Pearl Harbor has a BB-sized drydock which Missouri has already used once. Big museum ships need to bring in a lot of revenue to be able to do maintenance and be sustainable.
Everytime he crawls into small spaces, talks about curator nightmares and thin layers of plate it somehow reminds me of the Starslip comic.
You have the best job in the world 💯
That was such a fascinating video; these extreme edge spaces on the ship are so cool
Ryan, when you and your cameraperson go into these spaces do you do air monitoring? Continuous and with you? Radio communication and someone outside standing by, in case something happens? Rusty confined spaces are notorious for killing people.
Agreed, I'd want an O2/CO2 Monitor and a minder outside ready to arrange a rescue from A professional standpoint.
However as a nerd, I'd probably just haphazardly roam the ship lol
@@MickGallJrthat’s a great way to destroy the museum monetarily and also the reputation of the organization. Get shit done, but don’t do anything that’s going to cause damage to the ship or the organization tasked with supporting her.
Looking online. Portable oxygen concentration monitors and and portable CO monitors can both be had for $300 dollars and have a certified lifespan if 2 years. SCBSs are several thousand dollars
We have air monitors that we bring with us.
I’m willing to bet one of those is the same of the Sullivans. Waking up one day to find your ship slumped over in its berthing.
hope they do an ultrasound on that plate at the yard, just encase it needs to be re-plated.
There are curators and then there are BATTLESHIP CURATORS
The Sullivans listing problems were noticed around April 14th, 2022.
Another fantastic video
I would almost be tempted ro run another 6ft wide plate on the wind water line just for added protection
Rust
Water Encroachment
Fire issues
Conservation issues
Structural issues
electrical issues
issues with potential gasses and stuff still left over in the ship
Carbon monoxide
im sure the list is endless.. and every one of you do a damn fine job keeping her above the water..
I got a crazy crazy idea... 1500 volunteers.. a day.. setting general quarters on the ship properly.. something of that nature.. also.. closing watertight doors.. umm.. rotating a gun.. manning the rail weapons on at least one side for a period style pic.. the ideas are endless for what you could do on board..
Maybe show us the pumps used to fill tanks one day
🤗
I think it would be worthwhile to say something about air in confined spaces. I mean, I'm sure Ryan knows what he's doing, but I think it would be good to mention something to the effect of "don't go into confined spaces like these without planning for unbreathable air."
Fortunately they are dry spaces and unlikely to have mold or hydrogen sulfide. Kicking up enough dust and disturbing paint would be an issue as much of that paint is probably lead-based. Then again, he did say they were coated specially rather than painted, so it might not be lead based.
I dunno, I can think of a few nightmare scenarios for a curator. I call them the Four F's. Flooding, Fire, Funding, and Findings. The last one being hauling your ship into drydock only to find that half her hull is rotted out and needs replacing, when all you have the money for is some blasting and painting.
please don't scare the man out of his crawspaces!!
A flooding casualty combined with bilge pumps that are unable to keep up.
Put a hole through both sides is a lesson from Leyte Gulf!
Maybe replace the new waterline with stainless steel? I mean, you're not going to weigh her down, it's always going to sit at that new line, it's a known issue in that area (so just that area would get it) and you can put thin stainless on top. On commercial boats, they slap stainless on every patch, because it can be welded into regular steel and it does last longer.
I've seen fishing boats with nearly fully replaced sides, slowly done over time. All you need is a good welder and in theory... this is something that could be done out of dock since it's at the water line. You need a dam structure around the work area, which is something that has been done before and can be done with switchable magnets and you slowly chip away at the plating on the new waterline replacing it with i don't know 30~40 cm of stainless steel plating that then becomes a super long term repair to an issue that rightfully is a nightmare. Dunno, just my 2 cents. I'm of the opinion that in an historic setting (preservation) if a process replaces original elements of the historic item, but does it in a way that's not visible to the eye, and for the sole purpose of long term preservation, then that's ok.
And i say that in the context of working on buildings that are hundreds of years old, replacing the guts of rotten beams with carbon fiber metal composites, leaving only a thin stabilized veneer of the original wood. Sometimes you have to stuff like this, otherwise it won't be there in the next generation's eye.
Water torture is serious. Mythbusters did a segment on that
If this was Wisconsin....you would technically be sitting in Kentucky's bow...technically. 😉
It took job hazard analysis, confined space permit, tag out whole watch , extraction team . To inspect and repair at the plant. It was a 35mgw wood / dirt burner. And I loved it !
Can you do a video of what would be the procedure on removing the oil from Arizona's fuel bunker if the hull fails.
Hi Ryan, yet another fasinating video.
When you get into dry dock and have "bared" the metal, will you be using a thickness gauge (ultrasonic) to be sure you have more than just paint keeping the water out?
Any chance some extra plating could be welded on at the water line? Seems like a good precaution while in drydock.
Sounds a bit like the nightmare I had the night before I was to trade in my first car for my current one...
That first car had had no end to problems derived from sitting in a garage unused for more than six months a year under it's previous owner, for eight years and only getting ~7500km on the odometer per year before I bought it.
I dreamt that the car litterally fell apart piece by piece around me on my way towards the dealership and ended up half way there, on just the drivers seat on the floor plate, holding the steering wheel and watching the wheels rolling away to the curbs on either side ahead of me...
Everything else of the car spread out behind me along the way when I woke up drenched in my own, cold sweat...😢
I imagine that museum ships learn lessons that can be applied to the Navy's mothball fleet. The lessons can be applied to ship design as well. Knowing what previous ship design led to corrosion issues would help inform the design process.
Granted, I doubt the navy ever plans to design ships for longevity of several decades. Even if the ship is in mothballs.
None of the museum ships are "in mothballs." That is a term for a ship that the Navy still owns and has stored in reserve, carefully preserved and protected for future use. The U.S. Navy no longer maintains a reserve fleet - most of it was surplus WWII era ships, and almost all have been sold, recycled or sunk as targets since the end of the Cold War. New Jersey was in reserve between her active service periods, and for about a decade during the 1990s before being disposed of and donated as a museum.
@duanem.1567 yes, I'm aware that a museum ship is not in the mothball fleet. There's about 600 of them in this fleet right now.
The point of my post was that some efforts by a museum ship to preserve the vessel may be useful practices for the mothball fleet.
@@gobblox38there aren't 600 ships in reserve now. I don't think there are even a tenth of that anymore. Like I said, they were almost all disposed of, and we're not holding old ships in reserve anymore.
@@duanem.1567 I was mistaken. The information I cited was old. The mothball fleet is 100 ships.
Are there any thoughts or possibilities in regards to levelling the trim of the ship after her drydock visit? If so, how would that be done in a way that wouldn't harm long-term preservation?
You mentioned the waterline protection plate is sitting out of the water due to the ship sitting higher than in service. Are there any plans to extend that reinforcement downward to the museum ship waterline
Have you done ultrasound thickness measurements? Also, with rusting out from the inside, is dry inert nitrogen gas fill safe or sensible for that tank? It would make inspections problematic but keep internal rusting way down.
Two questions. First, on my USS Texas dry dock tour, Tom Scott pointed out an area at the bow where they had done ultrasound measurements to measure the steel thickness. I was surprised how much it changed from point to point even though they were only a few inches apart. Do you plan to do something similar? Second, are you considering doublers, ie welding on steel along the wind/water line as a kind of insurance?
Wow, can you hear how thin that plate is? You could almost punch through! Do you put dessicant in those spaces? It might help preserve the space since it takes so long between inspections.
I know it'd probably be expensive... but might it be possible to attach some sheet metal (made of a more corrosion-resistant alloy - maybe something like a "weathering steel") over the parts of the plating most in danger of rusting through? Not sure how much y'all can modify the ship to ensure its longevity, but if that'd be allowed and y'all could afford it, that might be the best long-term solution.
I'm sure there are coatings that could mask that so tourists won't notice/see it from the outside.
Alternatively... what about using cathodic protection to keep those areas from rusting through? Depending on what method is used, that just consumes a bit of electricity (AFAIK not actually all that much) and/or zinc, magnesium, or (possibly) even cheap aluminium blocks.
He talked about cathodic protection on previous videos. One of the problems with the current system is that it wasn't designed for fresh water.
In any case, I'm sure they're going to add some corrosion mitigation.
What is the even lower compartment marked 'Hold'? Looks hard to get any cargo into it.
I can't help wondering why they can't fill those areas with an inert gas like nitrogen. That would keep oxygen from entering and causing rust...
Tough to make air tight
@@tomhenry897 well they're water tight wouldn't that make them air tight?...
Would you be able to use scrap steel or other material as ballast to get the ship into trim?
👍👍
Those holes in that bulkhead would not reduce the weight aby any significant amount. They are more likely intended to allow fluid to move through the bulkhead when the tank is partially full.
Are you going to ultrasound any areas of the ship to determine what the thickness of the remaining steel in areas of concern?
who else watched those osha "this is how it happened" videos and immediately got worried about co2 pooling down there 😬
I am curious and want to suggest a permanent, maneuverable, solid ballast that will be evenly distributed to level out the bow of the ship instead of water in the tanks.
Not a lot of ways to do this to the scale of a battleship. You would need hundreds, if not thousands, of tons be it in sandbags or plates, to make the difference needed. And then you have to move them one by one. AND they would represent a complication should you suddenly need to fight flooding.
You were talking about intentionally flooding spaces, would you not just pump in something to those tanks that won't corrode?
Short term, might be more expensive, but longer term might help prevent a bigger expense...
If you had the funding, could you replate the thin parts with thicker plate
Assuming one could seal an exterior leak how would you pump out a completely flooded compartment?
Ryan talks about Class-struggle ?
Oh dear ... 🤣
Ryan - curious on your pronunciation of the Taney. Generally, anything named after Roger Taney or his family I've always heard pronounced as "Tawney."
The man was "tawney" but the crew always called the ship "tane-E" . Just a quirk.
Interesting. The crew obviously wasn't made up of Marylanders!@@BattleshipNewJersey
Hi, Ryan! I read somewhere that enclosed spaces on ships like where you are are inherently dangerous because it may not contain enough breathable oxygen or have toxic gas in it. How do you guys make sure that it's safe to go in there?
imagine having device from future that can detect composition of air ... seriously
rust in confined spaces eats oxygen, so just force ventilate it and measure O2 concentration and enter or dont
👍👍👍👍
Ryan has previously said that dehumidification was vital to preserving the ship in mothballs. Does the museum continue to use dehumidifiers to help preserve the ship? seems like they would be useful for areas like the peak tanks.
In some places we do.
Can you put thicker steel put at the current waterline?
It would detract from the ship's originality but have you considered putting say a new 4' high belt at the current water line out of say 1/4" plate steel? You certainly have the weight capacity for it with most of the tanks empty and no munitions onboard.
water intrusion ?
What if you knock on the side of the ship, and something knocks back?
That would require a diver, but it would be a really good April Fool's prank.
Worse your hand goes through.
@@randyogburn2498 And grabs Ryan as he screams and tries to get away?
EPIC!!
I got claustrophobic watching this video.
Then you should avoid watching Ryan's video on the splinter deck.
would it not be beneficial to add alot of ballast to the ship to lower her back to the normal water line?
What is that space that the hole is cut into the bulkhead?
If you're flooding sections of the ship for ballast with fresh water, would you add any sort of corrosion prevention to it? We put chemical corrosion inhibitors in our heating systems over here to stop it rotting the inside of mild-steel tanks, steel radiators, and the like - or any sort of deoxygenation?
It's a much smaller scale, but you've an interaction between copper pipe, brass fittings, stainless steel fittings and whatever Chinatanium that weird roughly cast socket is made from and since nobody over here bothers to maintain everything after it's turned on it keeps all the water in the tanks rather than out around the house.
It's probably too expensive on battleship scale.
Nah, just drop a few ingots of a sacrificial metal in there
Looking at what it took to get The Sullivans back up after her mishap, I don't think anyone wants to do the numbers on what it would take to get an Iowa out of a similar situation. Upkeep is cheaper than rescue, that's all one needs to say.
5:17 I always considered that oil was a preservative. Does it interact poorly with the paint allowing the water to get to the metal?
As for regular "oil/oils" that most people would run into, yes.
Remember that Arizona would be leaking old Bunker fuel form 1941, which depending on the type can be close to near unrefined crude oil which can already vary in acidity.
When USS Texas got turned into a museum ship they left a coating of it inside the fuel tanks thinking the same thing, only to find out it degrades when in contact with salt water and basically turns corrosive or acidic.
So Missouri being in the same water as the Arizona would not only have the already highly corrosive salt water, but the added corrosion of the leaking degraded fuel from the Arizona slowly eating its hull.
How much (solid) ballast would it take to put NJ at the prefered waterline? Are there enough spaces that are unlikely to ever be opened up the the public to scatter a hundred or so half yard totes of sand around to get her back to that trim?
The ship is approx. 10 feet out of trim, meaning in the current museum-era configuration (no ammunition, stores, fuel, water, oil, crew, etc), it rides 10 feet higher in the water at the bow than the stern. For drydocking this is an issue because being so far out of trim, when the water is drained from the drydock, the stern will land on the blocks much earlier than amidships and much earlier than the bow. This will concentrate too much weight on the aft part of the keel and prop skegs, possibly stressing the ship. The solution is to add weight forward. The ship does not have to be in perfect trim to land on the blocks, they calculated that it would be OK if they could get to 3'-8" of trim or less. To get to that measurement, they will layberth the ship at Paulsboro marine terminal and a contractor will add water ballast to the ship, aprox 500,00 gallons, or 2,000 tons.
@@SomeRandomHuman717 the number at the end and a little math from that suggest that for every foot of (uniform) draft you want to add you need about 400 tons of uniformly distributed ballest (e.g. about the same number of yards of sand). That seems /marginally/ viable for getting the water line back to where the metal is designed to take the corrosive attack. But viable and practical are not the same thing.
Could you say that Wisconsin's bow section is different because they had to replace a 100 or so feet at the bow Could they have reinforced any areas of the ship when they connected the bow from the Kentucky to the Wisconsin. And could the Wisconsin's new bow be in better shape because the bow is newer overall
Very silly question I'm sure but if the battleship sitting too high in the water is a problem then why not just add more weight? Fill rooms with lead shot for lack of a better solution. I imagine they don't want to fill ballast tanks with water because of corrosion?
Then you risk grounding the ship in the mud.
@@ghost307 OHHHHH that makes a lot of sense! Thanks for the reply :)
could you guys take on some kind of solid no corrosive permanent ballast at the bow so she sits lower in the water as she was intended?
Why would you want MORE of the ship in the water?
@@jimmiles33 so the wind/water line was the intended reinforced section.
eyyy he fixed his belt
Sometimes "no armor is best armor"
What's your process to ensure these confined spaces are "Safe for Men" before you enter them when not at a Ship Yard?
Like activating a ventilation fan/air pump?
Well, you need do more than that. Rusting steel can deplete O2. Should have a "Permit to Enter" process with a checklist and meters to measure the atmosphere in the space. Also person entering should probably carry a personal meter. Best:is to use a Marine Chemist to check the space. This can be life threatening. A retired battleship would come under OSHA confined space rules as the ship is not a USCG inspected vessel. Risk is higher. @@SonsOfLorgar
Do you have water alarms or humidity monitors to give you early warning of leaks in seldom-inspected spaces like this?
What if you used some used oil of some kind to flood some of the areas?
I’m sure that city generates 1,000,000+ gallons of oil of different types every day.
And 10 seconds after 3 drops leaks into the river the EPA will issue a fine that will dwarf the cost of the drydock.
How would you rate JS Yamato Aegis?
Design? Armaments? Role?
I'm curious what would happen if, IF, something like a leak did happen, what's the procedure to get the ship into a dry dock ASAP, emergency quick. Like, "we need to get into a dry dock in the next day or two or we sink". How does that work?
That isn't possible, all you can do is keep pumping water until you can get there. Look at Texas, she was pumping a whole lot of water constantly for years before she went to drydock.
@@BattleshipNewJersey ah!
Were those kind of problems some of what hit USS North Carolina?
this has me thinking. If a Iowa class ever sunk... would there be any compartments that would not flood ? even sitting at ocean floor.
I'm NOT an expert, but I would think it depends a lot on how deep she went. Sea pressure increases A LOT the further down the ship sinks. If she went too deep, and as he said the plating is very thin there, you would at least get some leakage or at worst an implosion of the peak tank
looks like a play place for curators :) no slides though :(
