Hey thanks for this explanation, tour guides didn't have a full explanation the other day, can't believe it was mostly after just a few years of neglect between yard periods.

[@robertf3479]

We had improperly coated and protected hull steel inside the ballast tanks of USS Nassau (LHA 4) that had all but rotted through, "I" beams made up of 1/2" thick steel that the Chief Engineer was able to scratch through with his knife. This was discovered just before we were to sail at the end of February for a Northern Wedding exercise up in the Arctic Ocean. We spent an unscheduled week and a half in Norfolk Naval Shipyard getting that framing beefed up. It's a good thing we did because we hit storms serious enough to send everyone home with moderate to serious damage. Hurricane force winds, sub-zero temps and 40 ft seas with a couple of rogue waves (60 ft confirmed) smacking us hard. The time it took for those frames and plates to be eaten through in a relatively new ship ... I can well believe what happened to New Jersey.

[@wtmayhew]

It is surprising the Navy was so careless with an asset as expensive as New Jersey. It doesn’t take a physics degree to get that painting over the studs is going to improperly insulate the anode blocks from the hull. The workers might not have known it, but whoever inspected the work should have known it. It is lucky that the damage wasn’t even worse.

Hi, Ryan. Is the impressed current system in the berth getting reviewed/updated while the berth is empty?

[@user-ux9my7io4p]

One question: Do the anodes cause any drag that hinders the ship’s speed, however slightly?

[@leftyo9589]

yes, but fairly minor in the overall scheme of things.

[@wyskass861]

Of course, but even if requiring an extra 1000 HP it would a drop in the bucket at a fraction of a percent of the ships 200k HP engines. Less than a slight gust of wind or a few waves on the hull.

[@chrismaverick9828]

I'm curious as to how much those pitted plates are compromised to deformation and fracturing. I know they are not the armor, and that NJ will never be facing a shell or torpedo again, but impacts from other boats and the dock could happen.

[@blainepalmer5205]

Hey Ryan, can you comment on the rivet construction and how it compares to weld construction on one of her sister ships? Does that make her weaker?

[@BeachBow]

I can understand metal to metal contact with the anodes. But do they use any kind of material between the hull and the anodes to help the anodes do their job? For instance, in computer work, we put a specific grease between the CPUs and the heat sinks to help in the transfer of heat. Is there something like that for marine stuff? JM2C

[@chadhartsees]

Wow, amazing how one mistake can cause so much. "Hey, we paint over these, right?" "OK!"

[@MrJamesBanana]

They do, they have an impressed current system.

[@yoshisaurusrex3767]

I know its not going to happen, but would the ship in theory be seaworthy with pitting like this?

[@jth877]

There is a certain amount of pitting (depth) that is allowed. Since NJ went through hull repair in 1987, then deactivated not much later and painted again, I assume what's there now would probably be ok. I did a dry dock tour 2 weeks ago, and the amount of pitting, especially in areas where there were no dissimilar metals, really shocked me.

[@redalertsteve_]

Yes. But youd need to get paint in there

[@rearspeaker6364]

they are now "aero" divots like on a golfball.

[@littlewazz]

are the anodes hardware stainless due to being in the water all the time?

[@redalertsteve_]

Yes

[@wyskass861]

Which hardware? The bolts or the anode material? The anodes are aluminum so that they are dissimilar to steel to corrode more than the steel hull. The studs and nuts are the same material as the hull so that they don't form another corroding system.

[@wyskass861]

@@redalertsteve_ That would defeat the purpose of the anodes wouldn't it?

[@Modellbauer403]

Is it possible to fill the pittings with steel? Or would that be a too huge work?

[@libraeotequever3pointoh95]

Possible, but not inexpensive.

[@wyskass861]

A weld bead into every one of the millions of holes would be an absurd amount of tedious work. If the plate is not corroded through, it's not a problem as long as it's cleaned and sealed over as they have done in this project.

[@garbo8962]

We all.make mistakes but you would think the ship would have a detailed inspection below the water line before leaving the dry dock that somebody should have picked up that the anode steel studs were painted and caused corrosion due to anodes were insulated from the steel .

[@kiereluurs1243]

At that time the corrosion hasn't really STARTED yet...

[@scubasky]

I don’t see how a painted bolt can be the issue, when a bolt is tightened down it bites into the threads with hundreds of pounds of force as well as scraping and scratching both the threads and the surfaces it is torqued to which should make a sufficient electrical connection.

[@oliverheaviside2539]

Get a multimeter and try it. You will find your hypothesis is wrong. The paint is still in the threads and is a dielectric; no significant current will flow.

[@ThatGeezer]

If there was a sufficiently good connection between the anodes and the hull, the anodes would have been corroded away far more than they were.

[@mfbfreak]

The voltage is in the order of half a volt. That means that any resistance, tiny as it may be, will have a large effect on the functioning of the anodes. A tiny layer of rust and paint will already isolate that half a volt. You are completely right when it comes to higher voltages, but even then you gotta keep resistance in check because at high voltage/high current situations, things can hear up very quickly when you introduce a tiny bit of resistance.

[@CJOlin]

That's exactly why the anodes failed as he explained. Someone back then, had the exact same theory as you...and it FAILED! So.... I'm guessing they won't be asking for YOUR input on whether or not to cover the anode studs.

[@justgetitthere]

So what happens if there's a delay on getting the work done
