These videos will become a treasured documentary that people will watch decades from now. Absolute treasure documenting this. Just a decade or two ago in the 2000s this kind of documentation wasn't even possible or available to the general public
True story
Well said!
The world might be over in a couple decades from now lol
It was possible just not as available.
YES!!!!!!!!
That has to be the cleanest hull I have seen. The Texas sure didn't look that good. You really have taken great care of this lady.
Texas looks amazing now plus they were docked in different places.
Fresh water probably helped.
Not sure how Texas looked, but it's funny how the old dreadnought is only, what, 30 years older than the Iowas?
@@GraingyAircraftbut iowas were US Navy ships until the 90s. Wasn’t Texas a museum ship by the 30s or 40s?
Texas was retired from naval service directly after WW2
I worked for decades in a shipyard. So on a inspect my job was to renew the anodes around the rudder and propeller. The Lloyds inspector was there talking to my foreman as I was setting up my job. My mistake was a ask the inspector what is the point of anodes. It turned out he has a degree in chemistry and start to explain to me all about rust and corrosion. My foreman silently slipped away.
Later on he laugh and explained the guy was smart however he also would talk the ear off an elephant if it stood near him long enough.
How dare someone share their knowledge enthusiastically to an inquisitor.
Had you listened you wouldn’t be on yt trying to learn about ship corrosion 😂
"Knowledgeable" can talk you ear off forever. "Smart" will ask what level of detail you need and want.
@@benjaminshropshire2900 smart would enthusiastically entertain the inspector in hopes that he would give you some flexibility in half-assing the job
@@BGraves Really smart would enthusiastically entertain the inspector in hopes that he would help you learn what parts of the job are actually important to doing good work and which parts are just there to create enough paperwork to make it look lime some regulator is doing their job.
"Half-ass'ing" a job is a good way to only get future contracts from people who won't be in businesses long enough to be repeat customers. Figuring out how to offer a contract with 95% of the value at a lot less than 95% of the price is how you cut costs to make long-term profit.
adopt a anode to raise money
as an ode to Battleship New Jersey
Such brave anodes sacrificing themselves 🫡
Some gave all, all gave some.
For those curious about rusting, Grady from Practical Engineering made a series of videos on rusting
Such a fantastic channel
Ryan, my ship, the USS Lexington, a WW 2 Essex class aircraft carrier, was drydocked in the very same berth. This was in 84/85. We were there for 10 months. The memories this inspires! We had to cross the deck of the USS Wisconsin to scrap parts off of the USS Shangrila! Oh the memories!
I wonder if that was the last time Lex was in dry dock
@@billdewahl7007 Probably. The Lexington/AVT-16 was decommissioned less than 8 years later. I doubt the Lexington has been drydocked since she served the Navy.
@AvengerII yeah, that was the last time for her.
The Lexington had the longest lifespan of all the Essexes. 1943 - 1991
@@billdewahl7007the Lex was decommissioned essentially the same as New Jersey but unfortunately the museum doesn’t do a very good job of documenting/ sharing her more modern history. Really they leave a lot to be desired.
Anyway, the last dry dock I can find record of was 1970. I do worry about her hull as she’s sunk into the mud and muck of Corpus Christi with no way to inspect her hull. She has an active cathodic system but if I’m not mistaken she’s about to be the museum ship with the longest time out of dry dock - if she doesn’t already have that title. Again really hard to find good info like this on her.
To stay on my soap box a bit longer, it’s a damn shame how she doesn’t have a social media presence. Not even a UA-cam channel - such a huge missed opportunity and so many Texans don’t even realize she’s there. Really huge missed opportunity to drive interest, attendance, and preserve her history, and memories.
I’m so happy to see the hull is in such good shape! I hope all of our Iowa class battleships will remain on display for future generations.
I wish I could see her in dry dock. Can't make the trip. Magnificent ship!!
Remember the ship was laid at Long Beach Naval Shipyard and ADM Tucker was a stickler for the work done on her.
Ryan, you are doing a fantastic job as curator. Very impressed!
Ryans becoming a great internet personality. I see a lot of people from around the world in the comments. Hes really shined a light on the Iowa class.
Watch out Mr Beast... Ryan is coming after your numbers!
I never seen the hull that clean after many years in the water. It clearly shows the anodes are doing the job it supposed to do. I can tell that Ryan is pleased how the hull looks and relieved that there's no major work needs to be done except to clean it and give it a good coat of paint that will last another 20 or 30 years to come.
These Anodes are sacrificial, so the fact the Anodes are in such good condition is not a sign that they are doing their job. On the contrary it means they are not doing their job, unless of course there are so many that their rate of consumption is greatly reduced. They are meant to be consumed.
An artificial impressed current system may be a better solution.
I guess I should have watched the whole video.
I’m surprised how little marine growth there is.
They *aren’t* doing their job because they’re salt water anodes. Shes in fresh water and needs aluminum or magnesium anodes. The reason the hull looks like that is there’s a lot less stuff growing in her fresh water berth than what ships in the ocean are exposed to.
If she was in salt water those anodes would be long gone (which is how they work, by sacrificing themselves not the hull)
@@cruisinguy6024 Well, Excuse Me !
Well put me down for one of those old zincs, that'll be a super cool souvenir.
Nice to finally see the bottom of New Jersey and I love the archeological mentality that you have. I was expecting the corrosion on the anodes to be worse. Just a point about the salt content of the river also, the USGS attributes the increase to runoff from road salt treatments used along the tributaries of the Delaware River and not the effects of climate change. We are seeing the same thing on the great lakes with over 1 million metric tons of chloride being used annually to treat roads here it eventually ends up in the lakes.
Rediculas amounts here in Michigan. They can't wait for 2 snowflakes to meet on the road so they can dump a gallon of chloride on them. Salt and gravel did the job for decades but they want cars and bridges to rust faster so out comes the liquid. Winter was bad enough now they spread chloride spring and fall on the dirt roads just to rust cars faster. UGH.
@@jefffrayer8238 A lot of lower population states are willing to allow people to run studded tires a lot more than higher population states. That allows them to run plows and salt trucks less, but at the cost of the studs eating the roads. (I know of one road that seems to get inch deep ruts repaired every other year.) The other option is to run enough more plows and salt (which also damages the road) to keep them safe without studs. I think it's a matter of "What combination of mitigation gets the best return for the least overall cost?"
If anyone is pushing for more salt just to make money, my bet is someone who sells salt and spreading equipment.
@@benjaminshropshire2900 Curiously, studs were still legal in winter in British Columbia in the 1970's. It's more rainy than snowy in BC.
@@awuma I don't know about BC, but around here, the days with rain and nights at about freezing are likely the times that studs are the most important because of the black ice.
@@jefffrayer8238, y'all have some of the largest salt deposits in North America. It makes sense, to an extent, that you'd use what you have locally. I know we've gotten shipments of Michigan road salt here in Nebraska, although I think Utah is our more common origin now.
One thing I've noticed already is the below water-line hull looks in remarkably good condition, which must be really reassuring for the sustainability and preservation of the ship. And seeing that the Impressed Current system is doing the majority of the protection work is also great news, it means the anodes on the hull can be the all important back-up system.
Between New Jersey and the Old Lady; USS Texas' drydocking and preservation work, it's an amazing time for Naval History, other museums are going to be pouring over the footage, designs and information the two ships are producing and hopefully means more ships can be preserved for much longer.
Stud weld means that Ryan's gonna do the welding.
Suggestions!! Could you make an episode talking about NJ Propellers? Why/ because of Numbers of propellers, number of blades and which kind of blades;
By the way, love your hard work for what your are doing for us/ channel, it so appreciated and informative!!! :)
We've been holding off on the props because that's where they are working so we can't really get back there, hopefully today we can find a few minutes when it's safe to get back there
@@BattleshipNewJersey I asked about this too. I can think of many reasons to have a mix of 4-blade and 5-blade propellers, but what was the reason(s) they were designed that way?
I spent many a day replacing those anodes on submarines while in the Navy.
Keep in mind that the types of anodes listed are indeed for steel/iron hulls. A different metallic hull makeup will need different types of anodes depending on the relative electronegativity/reactivity.
The only thing I remember from a Tom Clancy novel I read many years ago was the protagonist meeting a nice older couple in a seaside bar. They were stranded because the prop fell off of their boat. They told the hero that although they didn't know much about sailing they had hired a guy to go over the boat before they left and give them recommendations. One of the things the guy said was to replace the sinks, so the couple hired a plumber. But then the plumber told them the sinks were just fine and they figured the expert made a bad call. The hero figures out that the expert told them to replace the zincs, not the sinks and that's why the screw fell off.
So happy to see her in the dry dock. ❤
Who could possibly want to leave a paradise like Camden?!?
Watching from Australia, I wish I could get over there for a dry dock tour. But I’m really enjoying all of this extra dry dock content. All things going to plan ill be visiting the US in the summer of 25
27,692 lbs of zink anodes on that boat, the weight of ships blows my mind sometimes. I still think we should have 16 inch guns in service. The 16 inch 50 cal guns are awesome.
I have suggested in the past, that if New Jersey in Camden fired off the 16/50's they could easily hit the firing range at Fort Dix; just need to stop the inbound traffic to PHL.
When the USS COD submarine (SS 224) was in drydock two years ago, it was very clear to see the electrical-leakage corrosion on the 'dock' side of the hull compared to the 'water' side. Electrical current passing between the sub's hull and the metal dock structure ate away at the edges of the bilge keel. There are a series of UA-cam videos from that drydocking/hull repair. IIRC, the Cod previously had Zinc anodes installed, but during this latest yard period those Zincs were replaced with Aluminum anodes (better protection for fresh water)
When can we adopt an anode?
good idea
Watch out. They're not potty trained.
Like Pet Rock, but better!
I want one potty trained or not
I'm glad you're filming this yard period
Before this video, I had no idea what a zinc anode was.
I still don't know what they are,
but I do know I want one
What I would consider is alternating aluminum and magnesium anodes around the ship. The power screen method of a small charge in the hull has worked well on the Missouri. She is in heavy growth tropical waters
I visited U-505, in Chicago, a year ago. She's been on the hard for decades, and had no zincs. The mounting brackets, though, were noticable.
The docent didn't know what they were for.
Isn't the U-505 indoors out of water?
@@TheKilroyman Yep. That's why the zincs weren't replaced.
U-505 spent many years outside on the museum grounds before being lowered into the simulated bunker. The thin casing steel was a bit lacy.
The hull looks to be in pretty nice condition. Especially when you compare it to the work required on Texas. Granted, Texas is 40 years older and a riveted instead of welded hull, but that hull looks pretty smooth. Sitting in fresh water helps.
Hey Ryan.
We have talked before.
I'm the guy that asked about the rudders.
You said it would be too costly to reactivate the machines for the use of the rudders for a short time.
I would like to let you know,
it was a great and well informed video.
The New Jersey looks Beautiful.
Character with age.
Thankyou for taking care of our scariest war hero.
She is a fine lady.
You are a great person and I applaud all you have done with what little you have.
I wish I could afford a full restoration.
It is a shame we can't reactive her she is a warrior. She was but to fight.
I wish I could've seen her in her prime.
I saw a news report from Boston that USS Constitution is in dry dock to have its copper and other things worked on. Interesting that two of the most historic museum ships in the history of the Navy are in dry dock at the same time.
Don't forget the CV-10 Yorktown down at Charleston, SC. That's a must see too.
imagine all the research over the years that went into understanding sacrificial metals. So cool!
Thanks for showing this. I was in the us Navy but as a photographer mate unfortunately on a D.C. shore command. I visited a few ships during my time and was aware of anodes since I grew up on Long Island and spent a lot of time on the water. I never realized how much is required to reduce corrosion on a ship this size.
The panama canal has the same doors going for 108 years when we went through and the anodes were right there on them.
Poor Ryan. The weather up the east coast today was crappy. I got soaked from the knees down today waiting for a bus this afternoon, and that's with an umbrella.
This is the same method for water heaters and other systems that are constantly in contact with water. RV water heaters use a 1" x 12" zinc cathode rod for the same reason.
New Jersey has less rust than my car. That is impressive and good news!
I'm officially addicted to this process.
Hoping to get one of those zinc anodes.
And what will you do with it?
@@gkoproske Mount it to the wall in my office. It is a piece of history.
This is just absolutely fascinating.
There is... SO MUCH to ship design over the centuries that has evolved. Incredible.
Mechanic here, I HATE it when painters hit every thread! 😆
And then even better is when they paint over a thread with the nut already on it and you have to spin that thing off just a joy
Can't wait for the USS NJ zinc anodes to be available for purchase if they are somewhat reasonable priced i WILL own one of them for sure.
Thanks for you dedications Ryan
Thank you! Facinating information concerning the protection efforts to preserve the hull in the water.
Excellent explanation!!
Love to see a walk around showing the different locations of the anodes, especially in the more interesting areas around the rudders and propellers.
Never thought talking about metal rusting would be so cool. Love OSHA, you have a hard hat, no safety vest or even a navy PT belt :(
Living outside of the US and therefore unable to come to the drydock for visits, I hope that you guys document everything as much as possible and post it here on the channel. As others have said in the comments, this will become a documentary in itself for future generations and I suspect that over time the Museum can use these videos for displays in the ship when it is back
Wow, I was surprised how clean the hull of the ship looked after so many years. Maybe I thought it would look rusty, crusty, and full of marine growth. A Dazzle paint job would look really sharp on the old girl, very nouveau, lol. Great job Ryan.
to me it is incredible the amount of detail and work. this is history on its making 👌
Got my ticket, can’t wait to see this beauty down in the dry dock!
Thanks Ryan. This was something I was really looking forward to.
Very well presented. Thanks for posting.
Amazing info; did not know a thing about anodes/cathodes on ships. Thank you!
These videos are fantastic!
Can't wait for my dry dock tour Saturday morning! This should be so cool!
Thank you for new content on this historic project.
Looking good, nice job on the explanation of the protection systems.
OMG - Spectacular !!
I had a metal hulled canal boat ( fresh water) ,it was fitted with 4 sacrificial anodes welded on . When it was dry docked every 2 years ,the anodes were always nearly gone , but the hull was still as rusty as hell 😊
Nice to see the hull is such great shape. Whatever you are doing seems to be working.
Yes, I know won't happen but, It would be nice to see one of these old battlewagons sailing under her own power again...
Thanks for the great information.
I feel alot of people would want you as their tour guide.
Cool. When I served in her I got a kick out of the giant wrench in chow hall where hull was bolted together
I work in lightning protection and power earthing so the topic of cathodic protection and galvanic corrosion does often pop up. I have a business card that was given to me during one of our training sessions that we run for our overseas distributors and customers. He had on his card that his company were specialists in lightning and surge protection, power earthing, and CATHOLIC protection - yay for the printers "correcting" his order...
If I lived there, I would be buying tickets, this would be a once in a lifetime opportunity, however, I live here in Blighty so would be a bit of a mission, some years ago me & my Mrs was on holiday in Cape Cod, I did go to Battleship Cove in Fall River to see USS Massachusetts & was in awe of the size of it, I will be following this one👍
Definitely interested in purchasing an anode . Would go along nicely with the teak decking that I got from BB-62!!! Keep the awesome videos coming Ryan!! 🇺🇸👍
I love Ryan’s video’s. 🤘😎🤘
Looks clean enough to return to active duty 🙂
Grate video as always thanks
Looks very clean despite the years
I just designed and 3D printed a replica of the anode showed. A good addition to the collection!
I was involved with Cathodic Protection Systems for many years with a Canadian Engineering Company. Both Sacrificial (zinc and Aluminum) and Impressed Current systems (Ground Beds with Graphite Anodes etc). It is apparent to me that the Zinc Anodes are in such good condition because they did not have an intimate electrical connection to the Hull. Therefore they did not preferentially corrode. Ship Anodes I am familiar with had a heavy iron flatbar cast into them and these Bars were Welded, not bolted to the Hull Plates. Do not use Duct Tape to cover the studs which must be Seal Welded on. Not just tacked on 3 sides. Stainless Studs, lockwashers and self locking SS nuts. Slip some plastic tubing over them. Much easier to remove after painting. Will you be using a Zinc-Rich Primer with 2 or 3 coats of epoxy Topcoat? 6-7 mils Total DFT?
Great video...👍
Love these videos.
An amazing lack of marine growth on the hull considering she hasnt been dry docked for 30 years.
You are doing a brilliant job of looking after the Big J - well done Ryan and Team 👍
Great work, Ryan! Keep the news coming! Freetings from germany 🙂.
That was supposed to read: Greetings from Germany 🙂
This hull oks nice after 33 years under water.. Great!
The hull looks amazing. It's great to see it's in such good condition and the Battleship will be afloat for many decades to come. You and your staff have done a wonderful job preserving her for the nation.
I was shocked to hear a few videos ago that the fuel bunkers and pipes are "swiss cheese" though since like most, I had hoped she could somehow sail under her own power on special occasions, but you can't have everything I guess.
It's the seals, gaskets, and such that have failed. They've been dry for so long that they've rotted. The ship itself is fine. It's the kind of thing that isn't high in the list to check on, on a ship that's not going to sea. As for getting her underway again, it's possible, but unlikely. There is a distinct lack of those trained to fire up and run those boilers, handle the 16" guns and all the systems that are necessary to aim and fire them. I'm just glad that these Ladies have been saved unlike my ship, the USS Ranger CV-61.
Even IF, and that’s a big IF, the Navy would ever allow her to make steam again the costs would be monumental. Many tens of millions of dollars of repairs and restoration would be needed just to enable her to get underway.
There are a few WW2 era vessels that can still get underway, a LST and PT boat come to mind. ( I think it’s LST-325?)
But yeah the costs are just insane. Short of a massive and drawn out war with near peers I can’t imagine a scenario in which any of the Iowas return to service.
On that note, it would truly have to be a major conflict. There’s only a few dry docks capable of servicing ships this side and bet your ass they’ll be needed to repair damaged carriers and amphibs. Even if a new dry dock was built it’d take over a year to restore it to service. If there’s ever a need for them again it’s going to be a very very bad situation, and it’d be easier and more practical to build a modern battleship
@@cruisinguy6024 The nature of war has changed dramatically, and now UAVs in as great numbers as possible are the way to go, what with AI and inexpensive sensors and electronics. Who can produce the most autonomous and stealthy drones wins.That includes surface and underwater drones.
@@brianfoster7064 Thank you for your service to the USA👍
I'm imagining standing between the New Jersey and the side of the drydock when an earthquake gives everything a little wiggle. That would be a full blown code brown incident..
Thanks!
I was regular crew on a museum ship, the Alma, a Hay Scow (two masted schooner rig, built 1891) that was the equivalent of an aquatic UPS truck. She is ballasted with all the spare zincs for all of the museum steel hulled ships. Next time I'm aboard I'll have to count them.
I think it would be great if Ryan did a virtual tour of this evolution. Make it as detailed as possible. I'm pretty sure that those of us who cannot make it would be grateful to be able to purchase a DVD or Blu-ray of such.
Can't visit but happy to donate.
Ryan, keep up the awesome work!are there going to be photos and videos of her hull etc for those of us who aren't able to come see her in dry dock?
Put me on the list for a zinc what a cool peice of history and story to tell for years
So much you just never consider until you watch videos like this.
I want one of those Zinc Anodes!
Fantastic
I've been waiting for years to see those anodes 👀
Ryan has mentioned pancaking if a ship weer to be dryberthed. It would be interesting to see if there is any detectable deformation when she goes from floating to sitting on keel blocks, maybe by using a laser level on Broadway or having someone come in with land surveying equipment.
ive got my tickets. 3rd weekend in May and im so looking forward to seeing the ship. when you kept mentioning zinc anodes i was wondering why you werent going with aluminum.... and then you explained it.
Awesome!
Great video and project. I'm looking for something like this in or around Mobile, AL. I've toured the battle ship and submarine.
I got my dry dock tour ticket today. May 4th cant some soon enough
I am curious what the electrical cost of the Active Corrosion Protection, impressed current, is per year?
She looks really good.....compaired to the Texas hull before the work was done.
She looks great! Refit And send to the med!
would love to get my hands on a zink block!
Will you do a virtual tour? Love these vids ❤
English please.
