The Drum also has a very rare feature for a Fleet boat, 2 anchors. As far as I have read only 3 boats were finished with both and after that the various yards picked a side and stuck to it. Electric boat and Manitowoc build boats have them on the starboard side and Mare island and Portsmouth built boats have the anchor on the port side.

[@grast5150]

Answer: Yes - Unfortunately - USS Georgia 729 - I have been in the superstructure area, forward ballast tanks, Sonar Dome, and forward Sail superstructure as a SONAR Man. Ballast tanks are very slippery until the blasted out with hot steam water by the dock workers and dried when dry dock. The Sonar Dome is also very slippery inside which requires the use of dedicated hand and foot holds to replace zincs and inspect cables and tranducers. Climbing in tanks is the second worst activiy in my opinion. The only thing is that is worst is cleaning the 50,000 volt applifiers for under-ice sonar. I have been injured twice from those monster capacitors..Later.

[@CaptainHandbrake]

About the tanks and voids: I worked in shipyards before spending time in the US Navy. I have been in more tanks and voids than I can remember. Some of them are nothing more than dry, empty spaces filled with air, while others are ineffably disgusting. Some are even frightening when you first go inside. It is interesting to be both frightened and disgusted at the same time. Ships are a unique world, unlike any other I have ever experienced.

688 class new construction, Electric boat. Dry dock for some sonar inspection, large blocks along keel. Delivered message to sonar guys in forward ballast tanks. Ladder from bottom into lower vent, which was hinged for access. Hard to see much at my angle due to shadows, but more complicated than I expected. Inside PSWT, primary shield water tank for final close-out. Had to wear white coveralls and booties. No paint, just black finished steel. Looked inside main steam engine casing to support inspection of blades after first sea trials. Cramped, flashlights on tethers. Also saw USS Ohio in another area just before the three main hull sections were welded together into final hull shape.

Worked in a bunch of hoppers and tank-ish type of things, most were new and fairly roomy, so no big deal. The worst was crawling around inside a fire engine tanker. They're filled with baffles and there's always an inch of water even with all the valves open. I'm a big guy but bendy, had to slither in there and TIG weld a corroded through tube on the very freaking edge down low. Fun, fun fun. On the plus side, it makes for a good story and one more reason to complain about that stupid job.

My wife and I got to tour the Alabama and Drum I. September of 2019 after we got back from a Carnival cruise in Mobile. We ended up getting a tour of the Drum from a volunteer that worked there who was a former submariner. I don't remember his name but he served in the 60's. He was able to show us alot of things onboard and described in detail the life aboard a sub. My wife has never been a big history of military buff like me but due to his private tour she was fascinated.

[@tomtrenter3208]

Ryan: you are not in a NFO fuel (Normal Fuel Oil tank) but a FBT (Fuel Ballast Tank) FBT# 3, 4 or 5. NFO's don't have a flood valve in the bottom like in your video here, FBT's do. When fuel is consumed it is replaced with seawater by the sea water compensation system. When an FBT is empty of fuel it gets converted and used as a ballast tank. As one commenter said for every gallon of fuel consumed, in both NFO's and FBT's, it was replaced by seawater. The diving officer and his helpers have to keep track of all weights (fuel, food weapons, etc) removed or added and adjust the boats trim to keep from sinking or staying on the surface when trying to dive. It's very similar to aircraft weight and balance sheets. Diesel oil weighs less per gallon than sea water so the boat needs to adjust its trim to equalize it's buoyancy as it's comsumed. Because of the thin tank plating they are considered "soft tanks" and must be completely full of liquid, fuel and/or sea water, when submerged so they don't collapse. There are other tanks that are are considered "hard" and can resist the sea pressure when submerged. They are generally used for trimming the boat to make her neutrally buoyant when submerged and also adjust her to keep her level fore and aft. PS: yard workers did cut holes in the tanks to gain access for repairs and maintenance, that's why you see the circular and oval shaped "patches:" on the ballast tanks.

[@robertf3479]

A comment about the remark of how the submarine would become lighter as the fuel was burned off, if the tank is a "compensating" type with water being admitted as the fuel is used or vented, the boat actually becomes heavier. The specific gravity of water (fresh or sea) is heavier than the diesel fuel in that tank. Use up the fuel and the boat loses buoyancy and must actually be "trimmed" to return to the slightly positive buoyant state that most submariners prefer. Modern destroyers and cruisers also use fuel tanks that bring aboard seawater to replace the fuel as it is used in order to help keep the ship ballasted so she remains "grey side up." Earlier ships like the WWII Fletcher class DD did not replace fuel with seawater in the same tanks, normally not a real problem if you are refueling every three or four days, UNLESS you are short of fuel, have a bunch of empty tanks and are headed into heavy weather (Halsey's Typhoons for example.) You either flood the empty tanks to ballast the ship to keep the keel down or you could run the risk of capsizing.

[@DuffyF56]

Also this would be rough calculated before diving and trim adjusted and then done shortly after diving (trimming the boat) as no more diesel would be used until the boat surfaced or in the unlikely case of snorkeling if they were in the midst of a convoy. (Which the USS Drum was incapable of doing in any case though some Gato Class boats were upgraded for this ability later.)

[@geneard639]

When the Drum came to Mobile, my Grandfather (PFC WWI, DC1 WWII) who served on a Gato Class came to town to see it. My dad (AOAN) and grandpa showed my sister and I (AT1) around, talked a bit about getting stuck on a sub when he wasn't a submariner.

[@tonyperotti9212]

As a junior officer on USS Alexander Hamilton (SSBN617G) I had deck division for a while and spent a good part of one refit crawling through the superstructure and some of the ballast tanks on that ship. Lots of ways to bang your head. We also had a fire in one of our ballast tanks when we were in dry dock when I was the duty officer. Someone had left a drop light on some plastic sheeting and it caught on fire. No damage but there was a mess that needed to be cleaned up.

Yes, I was on USS Cochrane DDG-21. I worked in Gun Plot which was compartment 2-99-2-C. We went in the yards in July 81 and had major equipment removals and upgrades. This changed the ship's center of gravity. When we pulled the deck plates up in Gun Plot during the yard period, behind the MK-47 computer was a bolted-down manhole covering a fuel tank. That tank had to be drained of fuel, cleaned, and certified gas-free by the yards at Pearl. The reason was that the fuel tank had lead ballast bricks at the bottom. The yard had to add some bricks to compensate for the weight shifts caused by the multiple upgrades going on around the ship. I imagine the same process occurred in other tanks but since this one was in my workspace I had to work with the yard birds on it. Even after they re-sealed the tank Gun Plot wreaked of fuel oil for months.

Hi Ryan: I was in the Navy 68-72 station in Charleston SC and Key West FL. I was a IM Instrumentman. (a disestablish rate now) On the tender AS-16 Howard W. Gilmore. We repair and calibrated mechanical instrument clocks, gauges, torque wrenches, typewriters and adding machines. On the old diesel boats all the tanks had gauges that measured the amount of what ever the tank held. The ballast tanks had a hydraulic system kind of like the float in a toilet tank. The ball on the end of a arm compress a bellows that moves another bellows in the gauge inside the ship. Since the ballast tanks ran all the way up the side of the boat there were many ball arm things in one tank 5 to 6. I spent a lot of time in ballast tanks and the worst were fuel tanks.

[@consubandon]

In the Sturgeon-class, nuclear attack sub USS Bergall, SSN-667, prior to reflooding the drydock toward the end of the sub's mid-life refueling overhaul at Mare Island: I took a self-guided tour of one of the forward, port Main Ballast Tanks (MBTs) while the massive gratings that normally guard the seawater flood ports were still removed. All fresh, white paint inside. The clean smell is mixed with the salt breeze and the oil and steel air of the shipyard. You start out on your back against the outer hull and click on your flashlight. Lying there, looking up, the inner hull ("the people tank") is in front of your face; there's a curving space of about two feet between the two, concentric surfaces. Within that two-foot envelope, it's easy to slide on your back along the smooth, new paint, upward, against the outer hull... at first. Soon, your head is well above your shoes and it rounds the outermost flank of the ship, halfway to the top. You're sandwiched between two, curving, mostly vertical walls, fifteen feet outboard of where your entered. You can turn your head forward and aft and see the flat, vertical, bulkheads to either side of you, perhaps ten feet apart, that divide your MBT from its adjacent tanks, but you cannot see around the curve of the inner hull, looking either up or down. It becomes very dark when you switch off the flashlight, very confining and a little alarming, especially since no one knows you're in here. But the muffled sounds of drydock work make their way through the hull to your hiding place, and a faint light is now discernible, above, so you plant the edges of the soles of your shoes against the two, parallel walls, and continue your scramble, upward. In a few feet, what began as your ceiling is becoming a steep hill, and then, gradually a floor, so now you must turn over to put your back against the inner, pressure hull. You use the toes of your shoes to push on against the outer hull, and the faint light from above becomes somewhat more defined, though its source is still around the curving wall, out of sight above your head. Distinct taps and the voices of workmen are coming through the hull, above you. It's a little precarious, at first, as it would be easy to lose your footing here and drop between the two hulls, sliding onto your face as your feet bent toward the keel. Pressing on, however, it gets easier. You have climbed upward some thirty feet from where you entered, and you've become channeled now beneath the deck of the submarine, forward of her sail, with your back resting on the hull of the Bow Compartment. As you slide the last few feet to the top, your head moves up beside the Main Ballast Tank vent valve and its lever-like operating mechanism. The MBT vent is open. This is the source of the faint daylight that had guided the end of your climb. The flat, dish-like plate of the valve disk is retracted at a slant, beside you, withdrawn downward, into the MBT, perhaps open only a couple of inches at most along its forward edge. You can shift your torso and tilt your head around to look out through this slit at blue sky, the sail of the ship, and the scaffolding, above. Yard workers move about on the deck, unaware you are there, their boots walking just over your face. Their footfalls on the steel just in front of your nose are as loud as you might expect, but this is a marvelous spot from which to consider the vast progress made rebuilding your ship. You take a moment to rest, mentally sketch the arrangement of the vent valve operating mechanism for your upcoming ship's quals, then breath deep and resign yourself to the slow, careful slide, back down to the keel, where you can reemerge from the flood port (a flash of anxiety: it IS still open, isn't it?), checking cautiously that no one has seen you.... .

The lead ended up being scrapped to fund the restoration.

[@danquigg8311]

How was the lead actually removed? Lifted through existing hatches? Was the hull opened? Thanks

@@danquigg8311 hull was cut open and taken out by hand. They were like a short fat T shape and interlocked with each other. Not sure what they did with the lead. I was there getting boards out of the woods behind it. Bad summer storm tore up some piers(unknown where they pieces came from) and they allowed me to get all the wood I wanted.

You should see what you have to do to inspect a tank that holds radioactive water. That’s fun - said no one. I remember them briefing us and telling us to remove the plastic bubble around our head if we lost the air supply or we would suffocate.

Love these videos, Ryan!

[@jm10014]

Not Naval fuel tanks but, I've spent time in the dry bays and fuel tanks... drained and purged of course, of a C-5 Galaxy when I was in the USAF.

Ever make it up to Battleship Cove in Fall River MA Ryan? The Alabama's sister ship Massachusetts is there with the Lionfish, a Balao class sub.

Visited the park while evacuated from Hurricane Ida.

Add this is why he can't have nice clothes.😁 Looking at the structure between the 'dog' and the 'bun', I think the dog is just about ready to fall out.

I did some vibration measurements inside the aft fuel tank of an Egyptian strike craft (over the propellers) while doing 40kts, back in the early 80's. Rubber suit made it difficult to manoeuvre in and out.

I'm sorry....OMG square cut corners....AHHH...OCD is kicking in. Always radius cut...out of respect for her. They discovered in WW2, any square cut was where the steel would fail under extreme shock. Also, center punch marks had to be made with a rounded tip. Drum is a good boat, thanks for the video.

@T.J. Kong however, there is cyclical aesthetic loading...

[@paulbervid1610]

They did that to the u 505 until they were replacing so much. They built the museum around it.

My dad would drop us into the chambers of the septic tank after the honey truck would clean it out so we could scoop out residual mulch and had to fix the transfer pipes. This sounds Dickensian as I read this aloud ha ha. Dads.

Great video.
