I can see the pride and love that Ryan has for battleship New Jersey. Keep doing what your doing Ryan. We're all proud of you !
The whole team there has the same enthusiasm. It’s cool to see.
What a great video. I've watched Ryan develop from an awkward but enthusiastic contributor to someone who shows a genuine love for his job and above all the ship. Love it Ryan, keep it going.
And he still retains just a small bit of awkwardness that resonates with so many of us fellow history nerds. He’s not scripted, he’s genuine.
@@joelmacdonald6994 As an ex RAN member here in Australia, I like the way the USA has preserved a decent amount of history. We just scrap most ships here in Aus. Been wathcing Ryan progress for the last year or so, its awesome that this stuff is documented now.
@@colindonaghy8617 I’m not a vet or anything, but I am a Canadian, so I feel your pain in only having a few old boats. At the end of WW2, Canada had the 3rd largest navy in the world. And now we have a crappy navy(yours is FAR better), and only 2 legitimate RCN museum ships, We do have a number, but still a rather poor number, of civilian museum ships, but only the Haida and the Sackville remain as RCN vessels that were ever active. It’s disappointing.
Excellent idea to box the outboard shafts. Easily removable, but able to provide extra security to those shaft seals. I am so glad that many others beside myself have taken the drydock tour and have allowed the Museum to do this important extra work. Hat's off to all concerned !
Now my concern has been answered. Thanks to everyone who donated and was able to go do dry dock tours!
Let's keep donating so they can do the other extra plans
Ryan is doing everything possible to give New Jersey the best chance of a long life as a museum ship. I really enjoy the attention to all the details, it is very, very impressive!!!! There are just those individuals that are on this planet in the right positions at the right time. Ryan is definitely one of them!!!! Awesome work!!!! Thank you.
I was waiting for a flexseal commercial
Would have been a laugh riot to see Phil Swift on the scissorlift.
Missed huge money making opportunity 😂
We made this Iowa Class Battleship out of STS, and the outside is completely dry!
If the other 3 get a makeover, put this man in charge, he is THE MAN.
I was just on the USS Wisconsin in Norfolk today. I struck up a conversation with one of the volunteers there, and the conversation drifted to the other Iowas. Funny enough, Ryan’s name came up and the volunteer had nothing but the best things to say about him. Ryan helped the guys on the Wisconsin rediscover the officer’s barber shop.
All that to say, shoutout to Ryan and everyone working on the New Jersey. You are all doing fantastic work, and I look forward to someday coming up to tour!
This series of videos of the dry docking repair/restoration work has incredible. My deepest respect to you, your colleagues and the men and women working to preserve this magnificent ship.
I've never had any kind of special interest in battleships particularly, but randomly your channel was recommended to me about a month ago, and since then I think I've consumed nearly every video you've made haha. I'm hooked. Great storytelling Ryan!
It's great, isn't it! I got the algorithm's attention about two years ago, and have been hooked ever since.
I don't care about naval history, the most interest I would have thought I'd have would be the chain of 50 years worth of 18 year olds passing through its halls.
But Ryan manages to capture our attention with his love and knowledge for the ship.
Ryan, I have been to several ships. From Hawaii to California to Texas to to Alabama. You are quite possibly the most effective and aggressive curator I have ever seen. I'm ARMY to the bone but I appreciate your care taking of this beautiful ship.
Ryan has dedicated lots of time to the preservation of this ship. I'm glad to see he has succeeded in achieving the funding goals.
“Bold statement, I know.” In addition to being immensely knowledgeable, you’re funny! It’s a pleasure to listen to and learn from you, Ryan.
Be well!
R.
As a static museum ship it's a clever way to ensure the most vulnerable points are protected from flooding . Being removable does allow for any possibilities in a crisis . Rust is the main enemy in preserving these ships and the work presently being done should mean Ryan and his successors will only have the bilges and interiors to worry about for quite a while .
In a crisis situation, if the shafts would ever be operated again, the welds on shafts are a problem as potential fatigue sources. Perhaps the welded shafts could be pulled out, welds and parent metal ground smooth and all cracks removed, or new shafts manufactured. Not a show stopper but an extra nuisance anyway. But yes, otherwise, assuming that she will remain as a static museum ship forever, this fix sounds fine.
@@mhyotyni Not an engineer, but i'd expect the weld to not penetrate more than a couple percent of the thickness of the shaft, not really impacting it that much. But always open to learn more about metallurgy.
realistically the iowas will never be recommissioned. It'd be cheaper to build a new warship. Worst comes to worst they'd be valuable only for their steel.
There will be no crisis where these ships ever get used as ships again.
@@mfbfreak RIght, and the weld is far enough outside of the packing gland it's not an issue. That part of the shaft sticks out into the water, and is designed to be able to have a certain amount of depth of inevitable corrosion before needing to be replaced.
Suggestion for Ryan and whoever produces these videos. Time to time have a dry dock worker talk to the camera to explain what they are doing. Would be neat to mix it up with speakers plus it’s the only time they will be able to get these sorts of speakers 💪🏻
It would be awesome to see this but I don't think it'll happen. The doc would probably have a lot of reactions and the worker(s) would have to do it in their off time. But I do support this idea.
Who gonna pay them
@@maxstrWhoever is paying them now?
It’s called pubic relations 😂
No way ! Ryan is the curator , keep him speaking about ship he is very knowledgeable and you can understand him well ,
Did someone kill your dog or something ?
This is quickly removable for alien invasion, correct?
I'm worried about the exact same thing.
Nah, just raise steam and power away. Pretty sure the 53,000hp on each shaft will twist that thin plate into steel wool
@@tobymichaels8171 good point
Need to tell Ryan to lobby Hollywood better after all the tease for Battleship II was in the UK and an alien force might make a run towards the US to gain access to Nasa equipment or even Greenbank in WV and would go up the bay first to get close.
Naturally 😉
I brought homemade herb stuffing for the propellor stuffing box to the drydock tour. I was asked to leave.
Did you use sourdough bread for your stuffing? That's the reason you were turned away.
Haha! Battleship Kush!
Did they ask you to leave the stuffing as well? So they fleeced you out of lunch also
A great solution. It's lovely to see Ryan so enthused and caring for "his ship".
Are they going to repack the shafts in addition to the boxing?
Thank you Ryan for the videos. You do an excellent job of explaining things to those of us who aren't as knowledgeable on battleships and ships in general. And you interject humor into your explanations. You do a fantastic job, and I'm watching all the videos now, although not in order.
Good article in the Norfolk newspaper today.
As a rocket nerd, watching the guys the the UR scissor lift welding is doing my head in.
Battleships are cool too, awsome preservation work you're doing fo NJ. (apprentice battleship nerd)
Im glad this channel and ryan have found some success in this whole deal. Good people! Ive enjoyed binge watching these vids
It's funny we have stuffing boxes on our little 50 footers up here in Maine that we use to go lobstering. Pretty sure your stuffing box is a hell of a lot bigger than mine is 🤣🤣👍
As the shaft rotates, it doesn't "distribute the weight" around the packing. Gravity pulls down, regardless of the shaft rotating or not.
It's not nice to point out how little the curator knows about how ships propulsion systems work and the role of each component he pretends to explain to people who know even less than he does. I guess he hasn't noticed those struts and the bearing just forward of the propeller. The weight of the propeller is carried by a series of bearings from just inside the hull to just forward of the propeller, it is not imposed on the shaft packing. This lack of subject matter knowledge is a problem with museum ship people and CZcams culture and is really inexcusable. If those people don't know what they are talking about they should either hire people who do or just keep their mouths shut.
Dude, you really need a nice, relaxing walk @@oldtugs
Really glad Ryan and the team are doing videos on the dry dock restoration of battleship new jersey and creating excellent content about her and to help fund extra stuff for the project. It was really gutting the battleship texas folk have missed that opportunity content wise and seemed it was a bit here and there, but plenty of content from others like from Ryan's visit and the drone footage from a couple of chaps out there and of course the fantastic CZcams videos and in depth technical detail about battleship texas worked from Tom.
I went to see Iowa yesterday, got several kind comments from the crew about my New Jersey hoodie 🙂 The size of the turrets doesn't come across in the videos, they're massive!
oakum and lots of cosmoline?
Shes such a beautiful ship! Im always awe struck at her magnificence and enormity!
Glad to see that people are actually supporting the project and that the team can invest in further preservation work.
My friend and I did the dry dock tour today (5/4) and wanted to praise the entire Museum team and tour guides. I've watched nearly every regular and drydock video, but it was still amazing to be in the dock and able to touch the hull plates. Thank you for the great experience today and the wonderful work the team is doing to preserve New Jersey for the future. I managed to see the port side box in-person and our guides did a great job telling my tour all about it.
I got to tour battleship New Jersey as a kid when it first opened as a museum ship! I was in awe ❤
RYAN ,,GREAT VIDEO!! WE LEARNED ALOT...
This video will be in the manual 50 years from now. The people doing the work will need more technical details, but this video gives everyone a general idea of the plan, and you don't need an engineering degree to understand the broad strokes.
Class act Ryan!
Awesome work donors, curators and workers! She's looking great!
Have you thought about filling the box with foam to avoid future water intrusion?
Love the technology! I will definitely be making a visit when she's back, berthed in Camden
Belt and suspenders. Love it.
Great video!!
Id asked about renewing or (??) the shaft seals when you first headed to drydock. Glad to see such an intelligent and proactive step towards keeping the water on the correct side of the hull into the future. Clearly Ryan and crew are doing an excellent job trying to ensure the long term preservation of New Jersey!!👍
Zoomed in and saw what the welder was doing … “Kilroy was here!” Never met a guy named Kilroy. 😂
Thanks for preserving an important part of American history.
Thanks!
Great video keep it up thanks
Fascinating
Good Idea .
Love the actors in the background, really making this episode feel really realistic. Thank you!
Hi Ryan !
Good stuff
Ryan is almost as big a treasure as Battle Ship New Jersey. 🙏😵💫👍
Hi Ryan can you give us another video or short showing or giving us any more information to any of the following? Like how thick is the plate you are using to box the shafts? Have you got any footage of the gland seals being repacked, and what state were the seals and shafts of the inboard propellers, you mentioned previously that the docking skegs had been free flooded.
I know you also have another reason for doing it this way: there's still an extremely unlikely but non-zero chance these ships will be recalled at some point in the future, so you're doing this as an easily-removed modification. I respect that you're trying to maintain her as-is and not alter her for easier civilian access like they did with North Carolina, which had a huge hole cut in the rear of the armored barbette.
Ddg 995 had a shaft turning gear.Electric motor turned the reduction gear ever so slowly.Even in the yards the turning gear was active every so often.Not constant.The goal was to keep the shaft weight between shaft bearings from warping the shafts.Im surprised yours are locked in place for that reason.If they plan to reactive one would think they need to be turned periodically. But apparently they don't use turning gears on all sitting shafts.
What you are describing is called "Jacking Gear" and most active Navy ships have that feature. None of the battlewagons are going to be going anywhere so the Navy locked the prop shafts in place. Part of the contract between the Navy and the Museum forbids activating any part of main propulsion including releasing the shafts to spin.
Turning gear is also rotating the Reduction Gear before underway and also for cooling down the reduction gear from deployment.
They're. Not. Being. Reactivated. Ever.
@@dieselyetiwell. they. should. be. now. 😁
@@scottyb68 Uh huh. Why now?
Once boxing is finished are they going to fill the void with a lubricant or some other fluid to keep a positive pressure inside so water won't want to push in
Also even though the shafts are locked I still feel tides and especially towing may make the shafts flex a bit and crack some of the welds, so again a Heavy inert lude/filler
Clearly you are not familiar with welding...
@@Look_What_You_Didcare to elaborate?
Ryans explanation are so good ngl you should teach at one point imo. Like you are literally thinking before you explain it "what is that actually is the root of the evil" thats the most important trait period imo.
I still think that Ryan is using the dry docking as a cover for secretly reactivating the battle ship and is quietly assembling a rag tag group to steal the battleship and fight the Russians.
You spelled Klingons wrong!
Russians? I was thinking Aliens maybe out in the area of Hawaii.
Can you imagine the deterrent it would provide to certain forces harassing shipping?
Shssss.
That would be cool.
Will there be an inspection well between the boxed section and inside the ship so that any leakage can be identified before the void fills and eventually leaks through the packing?
What preservation techniques will be used for the propellers and the shafts?
Hey Ryan...how about a history lesson and tour of the actual drydock itself. I would love to know how it was built and how it operates.
With the inboard screws, since you have an access portal to the inside of the skegs, how about installing a jack screw under the shaft to take the weight of the prop off the packing?
I would think the inner ones would be the more concerning as the outer propellers are supported by the lantern bearings on that support structure, thus the outer shaft packings should only see some of the shaft weight between the last internal bearing and the external lantern bearing by the propeller (or are there no bearings on the shaft between the packing and the engine?)
In this drydock has all the welding been GMAW? I would guess original welds would be stick welded. Is anything on NJ tig welded? Great video!
It's most likely dual shield flux core wire.
Love the IOWA CLASS .
You going to interview any of the people working on NJ? WOuld be a nice addition to the channel. Their view and feelings on the old girl.
How is the stuffing box made and does it require regular operating? Once my father had a somewhat older boat, and in contrast to the teflon or whatever material that is used in modern boats, it had an old-school stuffing box filled with some fibers (hemp maybe?) and then permanently connected to a grease pump. Before starting the engine you had to give the pump a few squeezes to build up the pressure, to make up for grease that had dissolved into the water. And if we for some reason hadn't used the boat for a while, when going there to check that everything is ok we used to pump some grease into the stuffing box as well, just in case to prevent water incursion. I assume something similar was used on early-mid century ships as well? So do they require regular grease pumping to keep the water out?
Did you end up using the left over packing material that the Navy left behind, you showed it once, it was like a golden rope with grease.
Ryan, amazing job! Hey, are the gland seals designed to be more watertight while spinning? In other words, more likely to leak when not in use?
For some reason, I figured the shafts were bronze, like you'd find in typical civilian power boats,(some rare ones have monel shafts) but apparently the battleships have steel shafts, since they can be welded. That simplifies things.
Can you build a support on the inside of the shaft room inside the ship to help support the weight so it doesn't compress the seal
The 5 horizontal holes above-forward of where they’re welding…what are they for⁉️
Gravity is pulling the shafts down the same whether they're spinning or not.
you can supply compressed air from the inside to prevent water intrusion at all on the shaft boxes at all
How does this effect the ship as far as reactivation"? I would think it'd add more time.
Just a thought on the packings while in dock perhaps unlocking the props and giving a single rotation would be helpful before the boxing. Just thinking the lube and packing would settle from gravity as well so while you are protecting it now when that protection fails the packing will already be dried out.
Unfortunately, the shafts already have things welded to them by the Navy so they cannot move.
The locking plates are only bolted in place. He has shown them before@@johnzengerle7576
@@johnzengerle7576 Thank you but I mentioned unlocking them that the Navy would do with a reactivation. Though the Navy locked equipment they made sure it could be undone at need. They already did such on all the Iowas at least once, some in the very dock that she now sits. It may cost too much but even the contract requires her upkeep to keep her in condition for reactivation. Though at this point likely mute. Though it would cost too much I would love to see former ships like her to be able to move under her own power even if it was just once a decade. As she stands now she is more a barge than a ship. Even old ironsides USS Constitution sails once a year and stays on the ACTIVE DUTY list. Not just a historical relic. HMS Victory I will say is a building now as it is concreted in and supported with beams from the former dry dock. I enjoy History and it is a shame to render the old warriors to a permanent helpless state. A movie deal could even help pay for it like Battleship.
So that whole new welded assembly is watertight to prevent water even getting to the gland packing? if not wont the water just seep through the weld and you're still stuck with the same problem? awesome ship btw and great work your doing, I wish the UK would have saved more WWII Battleships, definitely gonna visit one of these site next time I'm in the US.
We're assuming the weld will be complete and not leak. Id hope it would be. I expect theyd do a quick pressure test to make sure its sealed...
How Is Ryan staying so clean. Working on a dry dock battleship all day.
He's taking a quick dip in the harbor to clean up obviously.
@@GrumpyIan is it cold?
@@jakeoreilly9627 Yes, that's why Ryan is so wide awake in all the videos.
I mean, he’s not the one doing the work.
You said the weight of the props pushed down on the shafts at the packing gland. Wouldn’t they cause the shafts to lift since the props are aft of the strut bearing. They are cantilevered on the end of the shaft pulling down at the strut but picking up at the gland seal. Great videos. Keep them coming.
Don't confuse a curator with technical ideas, it makes for bad selfies.
@@oldtugseven if I’m right, in the ga,e of battleship trivia, it would be one for me and ten million for Ryan.

Are these tours rain or shine?
What is the affect on the packing being dry?
when they dry out, they shrink, which allows leakage.
@@leftyo9589so if the collars fail it could be a worse leak than just packing the shafts normally? Or would they become engorged when put back in contact with water?
You mentioned that you once gifted another ship in drydock to learn some things. Have you been visited by other Museum ships while in drydock? What tips and tricks did you share with them?
Nothing to do with the subject of this video, but I’m wondering what all the various equipment does that’s on top and on the outside of the turrets for the main guns. I know there’s the rangefinders but there seems to be lots of other little protrusions and arms with pulleys on and so on.
New to the channel so forgive me if you’ve already done a video about it. I did do a search and I’ll look through all the turret related vids to see if it’s covered.
Cranes and periscopes
Thats a nice idea to protect this, but can this not corrode where its weldet?
Have you talked bout New Jersey "Pools" before
I served on the battleship Wisconsin when will she go to dry dock?
When were you aboard?? By chance during the period before her deactivation or prep for it??
Are they filled with anything?
Since those boxes are hollow, wouldn't be nice to have a zinc anode or two in it so when it fails there will be another cheap layer of defense to withstand until the next drydock in 2060?
What if any work is being done on the inside of NJ while in dry dock?? Thanks
Almost none other than minor work in progress. They're still working on the deck, afaik. The goal of the dry dock is to proof everything exterior from the waterline down (and a little bit above).
The only work above the wind-water line they are doing is redecking the area right around the gangplanks, because this is just about the only time they can do this work.
@@aserta nice was thinking of “A while it’s in the shop” kinda thing. 👍
@@jpoplin1 In Ryan's previous videos he explained that Time, Funding and size of Workforce negate any interior work beyond hull repairs.
Doing hull work during dry dock would be a waste of time and resources. Any work that can be done inside can be done while floating
I know this is a silly question, but what is the packing material made from, and how does ti keep the water out while still allowing the shaft to rotate?
synthetic cockroach furs.
joke.
Are the collars watertight or are they just there for support?
They are welded. Of course they are watertight. They are also air tested to be sure of that.
Are you replacing the seals as well? What about the shafts you are not boxing in, will their seals be replaced?
what shafts not boxed in?
Two inside shafts
No extinguisher seen there during welding time?
While I get the idea...whats gonna catch fire??
Would it be possible to support the propeller shafts by driving beams into the river bottom and allowing the propeller shaft to rest on them?
That seems like a lot of hassle for a dubious benefit.
That is by far the dumbest idea ever.
@@Look_What_You_Did Wouldn't go that far.
The ship rises and lowers with the tides
So is US New Jersey in mothball still and is it still owned by the Navy and you guys just get use of it for the time being? Jb
No- the Navy doesnt own the NJ any more. But they do have requirements for a certain level of upkeep, and rules about what the new owners can and cant do with the ship- like they arent allowed to use the engines. So they cant start sailing her around. If the ship was misused or not taken care if, the Navy has the right to repossess the ship but otherwise, the Navy really has nothing to do with her anymore.
Lets hope their welding is up to spec and there aren't any patches where the weld hasn't penetrated both plates, or water will seep in rendering it useless. As it 's being MIG welded that would be my biggest fear on something like this, it only takes a bit of impurity or contamination for the weld pool to become unstable and affect penetration, made even harder to identify while working in confined or awkward areas where you can't see what's happening very well. Are they offering any sort of integrity testing once the job has been completed? Dye testing for cracks is probably one of the easiest and fastest methods for identifying problems.
Id expect they'd do a quick pressure test on them...
@@wheels-n-tires1846 Had thought of that but it would be problematic. Don't forget that the gland seal isn't air tight, in fact they're not even fully watertight, hence the need for bilge pumps. Whatever you try to pressurise that space with is going to try and escape through the gland. I suppose you could try and fill it with a liquid and see if there are any external leaks, maybe with a UZ dye added. I was actually thinking filling the void with a liquid containing both a rust inhibitor and a sealing agent might not be a bad idea anyway. It would certainly be better than leaving it as an open void that will undoubtedly fill with seawater at some point.
@@Altair885 sure... I imagine thered be some leakdown into the seal, but it wouldn't be too difficult to determine that the weld was watertight. And maybe an extra step, but I don't think that filling the box with foam would be a bad idea. That'd pretty much ensure the integrity for a long time. That'd make it more fun if they hafta torch the box back off at some point though!!🔥😂
@@wheels-n-tires1846 Seems logical to me, if you're going to do the job it might as well be done right.
I would love to visit this beautiful ship, but I'm never going to the state of New Jersey again. Former BT USN retired OTR truck driver, lots of bad experiences in that state, it's a shame the residents have given up so much personal freedom to the corruption. But absolutely love and enjoy Ryan's enthusiasm and expertise, this man is a national treasure! Thank you again for all you do Ryan.
Out of interest, how do you prove / test that the "boxes" are indeed fully water-tight?
they put a moisture detecting hamster in the box before the final weld.
he is equipped with a nokia cell phone and a ration of seeds and nuts.
he will ring the deck at the first sign of water.
he is noble, trustworthy. and of the utmost levels of respect for his service.
Who is making the engineering decisions for what needs to be done to the ship?
Ratatouille.
⚓️
Wouldn't the navy have packed the shafts more tightly knowing the they we're never gonna move unless drydocked to remove the blanks anyway?
