I’ve attempted to watch some of the videos of other TH-camrs about this, but I just can’t, Ryan please don’t ever stop being the voice of history for this ship. You create a whole level of interest that no one else can touch.
Because Ryan actually uses conversational tone and dialog. It seems like he's actually talking with you in a conversation as if you were there with him in dry dock. Other TH-camrs feel like they are reading facts from a book or Wikipedia. Like they are giving a boring lecture. Ryan also gets to the point quickly and understands why we are asking our questions and what interests viewers.
I'm not even into military history, the Navy or maritime history but I've watched every episode for the past two years. I just thoroughly enjoy Ryan's storytelling.
As someone who served on USS Lexington, steamed the same boilers as the Jersey, drydocked in Philly Shipyard, and worked at the shipyards in Norfolk, VA, I really appreciate your videos.
I must say Ryan, as a history buff and a big battleship fan, Im so happy to see she is in good and capable hands for many long years to come. Im sure her sailors are very happy and proud that you will see to her well being for hopefully many long years to come. I made it to Philly a couple of weeks ago to see her in drydock and what a sight she was. I hope to see her in Jersey when she returns home, Way to keep her in ship shape and for the most part fully operational state.
Thank you to all those who have participated in the tours so that Ryan & his crew can keep addressing these types of issues!!! It is awesome to have the opportunity to take care of the vessel as best as possible.... Great work!
If all goes well, i'd hope Ryan is still Curator in 30 years if he hasnt retired yet. The way things get explains in a clear concise manner, the ease of listening too, the formats, the overall quality and knowledge. Very very few other youtubers have the ability to get all of these in 1. Ryans a treasure and just imagine the shear wealth of knowledge he will have even in 15 years time. Looking forward to the videos from all the years to come!
Battleship New Jersey Museum and Memorial receives operating support from the New Jersey Department of State, also from a number of other businesses, and private individuals like yourselves. It receives physical support from 292 keel blocks, and a giant honking concrete drydock.
I think Ryan is making the right decision on whats best to prevent corrosion on the hull for the next 30 years. I also find it interesting on how he takes on what options he can use or not use. It goes to show how he really cares about Battleship New Jersey future.
A "Much" older Ryan may see the next dry docking of the NJ in 30 years, but I have my doubts on myself. Even if I do I would be 101 years of age. Thank you Ryan for all that you do in keeping the battleship New Jersey as a memorial for future generations. Shalom
So glad to see New Jersey getting the maintenance she deserves after so many years of faithful service. Thank you as well for answering my earlier question about maintaining the ship near the keel blocks. You’re doing an awesome job Ryan and I look forward to the day New Jersey is 100% restored. ❤
Congrats on the success of your tours and being able to add stretch projects. You realize you're the reason that worked, right? You built a following through your videos and now that is paying off handsomely.
I have been amazed while watching your TH-cam posts at how many holes have been cut or drilled in the hull over the years. As a land lover I would never have thought they would do such things.
Ryan, excellent video as always. Thanks for sharing the in-depth details of the work being done on the ship. Very informative. Random question - what brand of shirt is that? Thinking of picking up one for work wear. Thanks.
Doublers are probably the best for a museum ship where you want to keep the original material . The quality of welding and preparation will be all important I would think .Ryan does a great job of explaining the choices and limitations of planning a docking . It's great that the scope of work can be expanded to make sure New Jersey stays afloat without undue concern can be achieved .
The Canadian Flower Class Corvette HMCS Sackville had its underwater hull completely replaced by modern steel as after the Sullivans partially sank, I had the question to other museum ships in NA like Sackville of how would they avoid suffering the same fate as the Sullivans
When things are that bad, there's no point in trying to save anything. That's wishful thinking. But in this case, NJ's actually decent. Still thicker than other (functional) ships. For a static ship, the extra plate is belt and suspenders.
this seems like a way to coat under the blocks without refloating. coat under the now missing blocks then replacement with wedges and blast out the other ones
Every time it's released, the hull will sag a bit relative to the remaining blocks, so I'm not sure that's viable. Maybe if all other blocks were blasted out too to balance along the ship's length, but at that point, is it any less work than just floating the ship over.
Interesting. I worked a dock for 3 years. Never removed a block. We got em in and got em out. Was pretty efficient and a bargain for the Navy. We were sailors after all, and we rocked. Bet no sailors drydock a ship anymore.
Thats a lot of steel thats been eroded away. Impressive. I remember watching an old movie on the mothball fleet and they gave some insane statistic of the weight of steel that rusts away from the fleet in a given year from just sitting in the water. I don't remember the number, but it was a very large one.
Could you explain how this added plating will be coated after welding to the original this mild steel? Also, did you say the welds will be 100z% around the edge, making the inner sandwiched areas waterproof by way of a sealed plate seem.
Thanks for posting about this. I took the tour this last Sunday morning (w00t!) and they were talking about this. It's great that you're posting further details. Is there any possibility that the plates you're welding on are enough different that you'll get dissimilar metal corrosion? Or can you eliminate that possibility with testing?
The main issue with Doubler plates and has caused vessles to sink, is you have no easy way to keep an eye on the corrosion levels of the hull between the plates, that could allow for corrosion to go unchecked till the doubler plate itself cant stay fully sealed and now you have water intrusion thats more difficult to repair. I would consider doubler plating with a heavy heavy distrust. Then again im not a ship builder, and only know from the incident reports ive read.
They could use flanged pipe penetrations welded to the inner hull where they have placed a doubler plate these bosses will have two valves on them they act as a tell tell open the inner valve for a period than close, then open the next valve any water that has accumulated between the hull and the doubler plate should be observed,they are normally welded at the lower side of the doubler with 40 or 50 mm pipe.
Does leaving the ship on those blocks affect the underside of the ship in terms of its weight is there a limited amount of time it can be on the blocks?
Will there be a video showing the entire hull so future generations can see what the hull was like when NJ was drydocked? Also including what you found and what work was done this drydock event?
Back in the day, and in the dead of winter in Montreal, my father who worked at Vickers as a plater had to break those blocs using wedges and sledgehammer. People were build stronger in those days.
The hull was built with only 10 mm plate on keel/bottom plating,are you sure? i am working on the RN Type 23 Frigates the plate thickness around that area is 20mm at the keel to 15mm /10 mm upto the bilge keel,10mm/3/8 seems a bit thin for battleship construction.
I would've thought that when the Navy brought it out of decommission status, they would consult the records and find that they completed the first area and the second, so now it's time to do the third. That way they wouldn't skip any areas over time.
I would have loved to have seen her in dry dock, unfortunately I am recovering from surgery and could not handle all of the steps. Keep up the good work and she will still be here in 100 years.
Do you plan to cover the doubler plates with the system of coatings and gap sealing caulk to ensure the plate won’t have problems to the best of your ability through 2050?
Are you guys comfortable with a 30 year stretch between dry docking? In a perfect fund raising world would it be cheaper to do it every 20 years? Would catching on going damage faster be cheaper to fix?
Isn't slapping on metal plate on top of another plate and welding around it would let rust form between? The navy would never do such a thing either. As much as preserving as much parts of the ship, as recieved, is important as a museum, compromising on something to make that happen doesn't exactly sound right. Or there is something on it that I don't know yet.
Ryan, May I suggest that you start a 'To-Do' list for the next dry-docking now. Hopefully either the much older you, or your successor doen't have to go through as much of a discovery process.
To prevent any water intrusion, couldn't you "trowel on" a thin layer of that epoxy before welding the doubler plate? That would fill any possible void between the two plates wouldn't it?
Depending on the sealant/expoy, it won’t cure properly, creates too much of a gap to get a good weld bead, won’t bond properly to the existing system of coatings, or expansion cycles might damage the weld bead as the material flexes. There are a lot of different engineering things at play here, but hard to know for sure without knowing exactly what they’re doing.
Then you have a gap between the epoxy and and the plate, no matter what you do there would be a gap, the only way that truly add metal and not have a gap short of cutting out old and putting in new would be pad welding the hull via weld stringers. Butt that would be ugly and cause some pretty severe warping of the outer plate unless they let ample cooling between each pass, which after a certain amount of time would still get extremely hot unless you really really let it cool off 100% between passes. That would also be extremely slow and expensive, and with how thin the metal is a high chance of having leaks due to welder blowing a hole through it and not seeing it. 1/4 inch is not thick at all in the welding world. Structural tests are given on 3/8” plate.
2:13 Battleship New Jersey ,there is no link "down below" in the description of this video. As a matter of fact : there is almost no "description" in the description information drop down. Just "transcript of this video". ⚓ ⚓
I thought you all had already put what you considered to be the "minimum" number of keel blocks under the ship, yet now you are removing even more? Does this risk cracking structural members in the hull?
The doubler plate does not restore the full bending strength or stiffness of the wasted metal because it is not fully bonded to the substrate area, but it does provide equivalent material for wasting.
Considering the coating was in good shape and what you're putting on there is even better, I'd have left it alone and left the money in reserve for other upgrades or put it towards that next 30 year dry dock. Thanks for sharing.
I have some fear about the air gap in between.. I hate rust - and even more so rust I can't see.. Though I suppose at the bottom of the ship no one is going to see anything!
I agree. Either leave it alone, or cut it out & replace it. By just welding a plate over it they’re potentially inviting problems they’ll likely be unaware of.
If nothing happened more since 1990 I would have just left that with a good fresh paint job welding two plates together and making a area between is scary to me
Why remove the keel block entirely? Can't you just shift the keel block to another area? That way you don't lose support while you're doing work under the ship.
It doesn't work that way. The blocks are placed based on the design of the ship's hull. They can remove a few, but you can't move them randomly. Besides, to move them would require flooding the basin and that's time consuming. They'll be doing that before long to move the entire ship four feet to allow them to finish the coatings where the blocks are currently sitting.
Removing a keel block opens up 12 linear feet of space to apply the doubler plate. Instead of alternate 4 ft spaces, now you have 12 clear linear feet of space.
I'm curious about why that'd be a six-figure project. Not that I think you're overpaying, I just don't understand where the costs are. This is what, a few hours of pressure wash to remove the blocks, a ton and a half of readily available sheet steel, and 320 linear feet of weld? I wouldn't be surprised by low five digits for that, but I'm clearly missing some steps here if it's six.
I'm surprised no one has come up with a way to glue 1/2" sheets of plastic to the hull and plastic weld the seams between sheets. I'd think, for a museum ship, that'd be better than steel.
I’ve attempted to watch some of the videos of other TH-camrs about this, but I just can’t, Ryan please don’t ever stop being the voice of history for this ship. You create a whole level of interest that no one else can touch.

This is the truth! :)
Ryan has internalized a massive amount of knowledge about the ship, so he can easily talk about it. I hope he is around for the next yard period!
There are other videos about removing keel blocks from under battle ship NJ?
As someone who served on USS Lexington, steamed the same boilers as the Jersey, drydocked in Philly Shipyard, and worked at the shipyards in Norfolk, VA, I really appreciate your videos.

Congrats on the success of your tours and being able to add stretch projects. You realize you're the reason that worked, right? You built a following through your videos and now that is paying off handsomely.
Ryan, you”ll still be in charge for the next dry docking. Thanks for another great and informative video.
So that's how it's done! Always wondered how you got to paint where the keel blocks are.
Ryan you are the best and only thing I appreciate about New Jersey, having been born and raised there.
what about the Boss?!?! MY new haircut>>?
You guys are taking better care of NJ than the Navy did
Can't afford not to. It's going to go 10x as long without maintenance, and it's now an OLD ship. You gotta take care of the ol' girl.
USN never wanted to reactivate those. The age of the battleship ended long before the politicians understood.
Totally agree
They kept her in running condition.
The idea that each successive team started counting from one is interesting.
LOVED my tour of BB-62 with you on my 65th birthday. I look forward to another tour with "much older Ryan" in the drydocking in 30 years!
I have been amazed while watching your TH-cam posts at how many holes have been cut or drilled in the hull over the years. As a land lover I would never have thought they would do such things.
See when Ryan plays Jenga he uses a battleship to make things interesting
Now that's funny right there!
Ryan, excellent video as always. Thanks for sharing the in-depth details of the work being done on the ship. Very informative.
Random question - what brand of shirt is that? Thinking of picking up one for work wear. Thanks.
I think Ryan is the smartest, most passionate curator out there. 😊😊😊😊😊
hmmm, that statement is helped because Paul Farace isn't an official curator of USS Cod. Then again, Ryan introduced me to Paul.
@@Tuning3434 That is so cool that you actually know Ryan and Paul
This guild of wizards maintaining the knowledge of old
Thanks Ryan for all you do.

There must be some kind of paste they would use between the new plates and the hull to eliminate as much empty space as possible.
Ryan you are doing a fantastic job, keep up the great work
Ryan might opt for the extra under coating , fuzzy dice and the spinner hub caps - Earl Shiibe for $29.95
Lmao
I would love to see her in the Black Dragon scheme please. We know Ryan loves that scheme too!
Maaco just under bid them and is throwing in 2 pine tree air fresheners
You're the only TH-cam curator I can stand. I've tried watching the others and the cringe is insane
As always….interesting.
Ryan, I’ll be about 90 the next time New Jersey’s in dry dock. I expect you to be there for a personal guided tour. 😂
The Canadian Flower Class Corvette HMCS Sackville had its underwater hull completely replaced by modern steel as after the Sullivans partially sank, I had the question to other museum ships in NA like Sackville of how would they avoid suffering the same fate as the Sullivans
HMCS Haida had a bunch of hull and other work in 2002 and 2015. 2002 was when Parks Canada took her on and she was moved from Toronto to Hamilton.
When things are that bad, there's no point in trying to save anything. That's wishful thinking. But in this case, NJ's actually decent. Still thicker than other (functional) ships. For a static ship, the extra plate is belt and suspenders.
You do such a great job talking about this wonderful Ship
Saw, you on the news a, few days agp funny because I was already subscribed and stuff.
Bravo Ryan, you are the Best.....
Did my drydock tour last weekend. Drove up from Northern Virginia. Definitely worth it.

That is the nice thing about steel. It is easily welded using electricity. These days, they even weld some skyscraper joints.
Glad I could contribute to the extra task going on with the extra money from fry dock tours. I enjoyed it very much. Continue doing fantasic work.
Thanks 🙏 for the update Ryan 🔥
Interesting. I worked a dock for 3 years. Never removed a block. We got em in and got em out. Was pretty efficient and a bargain for the Navy. We were sailors after all, and we rocked. Bet no sailors drydock a ship anymore.

To get to the other side! 😃
If you use a doubler plate 'glue' it to the hull so no water can get in and weld it as intended.
Will there be a video showing the entire hull so future generations can see what the hull was like when NJ was drydocked?
Also including what you found and what work was done this drydock event?
the big tan line is i am assuming the caulking you were talking about in another video?
0:59 Keel block no 81 looks a bit sad. Someone give him a hug on the next dry dock tour!

Hopefully cryogenics technology will advance quickly enough that Ryan won't be as old as he might expect to be when the next dry docking rolls around.
How are you going to roll the plates to match the contour of the hull?
Good reason to go 1/4". The yard should have plate rollers, most ships have curved bottoms like this.
I wonder if the material that is used for spray-on truck bed liners would be useful.
When is the re-floating to move it 4 feet?
I will be there on Sunday May 19th
I will be 110 in 2054, looking forward to being there!
I wonder how many times he's used the phrase "System of Coatings", At least 200 for sure
Will you also be painting and coating the doubler plates too?
Obviously…..
So Wise , Thank You
Fantastic !! See you this weekend!
How do they form that curve in the new plates you're adding?
Seems like a rather heavy responsibility.
That's an understatement.
Yuk yuk yuk
It steels the show
Hope you're using a bedding compound. This should prevent water ingress between the plates as it fills the gap.
I would have loved to have seen her in dry dock, unfortunately I am recovering from surgery and could not handle all of the steps. Keep up the good work and she will still be here in 100 years.
Do you plan to cover the doubler plates with the system of coatings and gap sealing caulk to ensure the plate won’t have problems to the best of your ability through 2050?
Will the new doubler steel plates be painted to protect against corrosion?
Amazing work. I hope to make it down to see it some day. And it sounds like it should still be around when that day comes.
Are you going to apply the full system of coatings to the doubler plating?
In the 60s to lighten their AFX cars the manufactureres deliberately acid-dipped fenders, doors, bumpers, even whole cars.
Are you guys comfortable with a 30 year stretch between dry docking? In a perfect fund raising world would it be cheaper to do it every 20 years? Would catching on going damage faster be cheaper to fix?
Hope you remember to check and repair the burnt off paint on the inside of the hill where the welds damage it.

As much as preserving as much parts of the ship, as recieved, is important as a museum, compromising on something to make that happen doesn't exactly sound right. Or there is something on it that I don't know yet.
That's one of the areas of higher stress during normal operation, perhaps that contributed to faster corrosion too.
Wondering if flame spray build up might be an option to build up the steel?
Ryan,
May I suggest that you start a 'To-Do' list for the next dry-docking now. Hopefully either the much older you, or your successor doen't have to go through as much of a discovery process.
We will definitely have a lengthy report for our successors to use as a guide for next time.
".....liquid metal epoxy..." JB Weld !!!
On a serious note, Belzona is a series of products, nine categories, worth looking into.
To prevent any water intrusion, couldn't you "trowel on" a thin layer of that epoxy before welding the doubler plate? That would fill any possible void between the two plates wouldn't it?
I was thinking the exact same thing. Basically why not to "glue" inside part of the plate while welding the edges.
Depending on the sealant/expoy, it won’t cure properly, creates too much of a gap to get a good weld bead, won’t bond properly to the existing system of coatings, or expansion cycles might damage the weld bead as the material flexes. There are a lot of different engineering things at play here, but hard to know for sure without knowing exactly what they’re doing.
Then you have a gap between the epoxy and and the plate, no matter what you do there would be a gap, the only way that truly add metal and not have a gap short of cutting out old and putting in new would be pad welding the hull via weld stringers.

I would say hydro-dynamic erosion would be the cause of plating thinning out.
I thought you all had already put what you considered to be the "minimum" number of keel blocks under the ship, yet now you are removing even more? Does this risk cracking structural members in the hull?
How is the heat from the welding going to affect the existing coats on the hull?
Good question adversely impact it I would guess
What does the "blocking position" mean?
Exterior corrosion or internal? I would think internal. Bilge area?
An idea for a video while I dry Dock, would be to talk about the pit sword again, and show where it comes out of the ship, if you can find it lol
The doubler plate does not restore the full bending strength or stiffness of the wasted metal because it is not fully bonded to the substrate area, but it does provide equivalent material for wasting.
Why has Sabaton not performed on the New Jersey or Texas while they’ve been on dry dock? That would be kickass and would raise a lot of money
Wow, fancy a jet wash that can cut through a yard or more of solid wood!
Considering the coating was in good shape and what you're putting on there is even better, I'd have left it alone and left the money in reserve for other upgrades or put it towards that next 30 year dry dock. Thanks for sharing.
I have some fear about the air gap in between.. I hate rust - and even more so rust I can't see.. Though I suppose at the bottom of the ship no one is going to see anything!
I agree. Either leave it alone, or cut it out & replace it. By just welding a plate over it they’re potentially inviting problems they’ll likely be unaware of.
Yeah those doubled plates fell out of fashion because of rust jacking. Rust starts in-between the plates and jacks them apart.
i really hope im going to be able to see you promoting the drydock tours in 2054 😂
I hope they take a picture of the check when they pay the yard to show how much this whole thing is going to cost at the end!!!
So they're not afraid of water getting in between the 2 layers?
If nothing happened more since 1990 I would have just left that with a good fresh paint job welding two plates together and making a area between is scary to me
So why do anything, if there is not any new wasting of the steel??
Why remove the keel block entirely? Can't you just shift the keel block to another area? That way you don't lose support while you're doing work under the ship.
It doesn't work that way. The blocks are placed based on the design of the ship's hull. They can remove a few, but you can't move them randomly.

You all keep removing keel blocks. You're making me nervous about walking under the ship. :)
