Inside the Propulsion Plant of the World's Fastest Battleship

[@disgruntledconservativevet1798]

Flash back! I was a Boiler Technician in the Navy (BT3). It was hot and dirty, and smelled like diesel. You were the first one on the ship, and the last one off the ship. 18 hour days was the norm while under way, and you prayed that there wasn’t GQ (General Quarters), man overboard drills, or anything else going on while your trying to get a few hours of sleep, if you even got any at all. 6 hours on watch, what we called 6&6 with a full work day in between watches was our underway schedule. A friend was an MM2 on this very ship. Being a hole Snipe was the hardest job on the ship. I retired as an MRC (Machinery Repairman Chief Petty Officer).

[@neilhoffman3051]

I had a good laugh when he talked about 4 hour shifts. If we were 4 and 8 we had a full workday as well. I was a hole snipe on the USS Midway for more than three year and we almost never went 4 and 8.

[@jimhmod]

@@neilhoffman3051 Yep, the 4:00am to 8:00am watch in the morning, then 8:00am to 4:00pm regular shift to perform maintenance, cleaning and such then the 4:00pm to 8:00pm watch. I remember not seeing daylight for several weeks just because I was too tired to go outside and went straight to my bunk at around 8:15pm to be awaken at 3:30 am. It does make for a hard man!! On a side note, while in the Long Beach shipyards, I painted all of the brasswork in the forward boiler room white because a thought we had much more important work to do than Never-Dull the brassworks. My four years was up shortly after the shipyards and I don't think anyone ever noticed the painted brass. BT-5 USS Towers DDG-9 1976-1980 Boiler inspector for 10 years after the Navy.

[@briangibbs4735]

My first ship was the USS Independence CV-62 not to throw any shade and I was on your ship or part of your command. down in 2 main the only people on 6x6 were individuals who were lacking qualifications. You have to remember other than qualifying for watches , new sailors only have 180 days to become damage control qualified, you also had to study for advancement tests. Down in our pit, the goal was to have a three section watch standing, both while at sea , but in port as well, throw in General quarters for training , the most difficult time is during Navy wide ship requirements prior to deployment. the ORE ,PEB. and OPPE just to name a few. Many times you will have BEECe drills where you simulate different plant problems that you might encounter. so you might see that while 6x6 sounds difficult. can you imagine if during your 6 hours off you had general quarters and did not sleep and then you have a six hour watch, do this for a few days. its unsustainable . so we always had 3 watch standers for each post. Me? I am MMC(SW) Gibbs, and I didn't go into duties and responsibilities for each watch station ,

my dad was a BT3 (51-55 total service years) and ran #1 fire room on a DE and an APD. they didnt have a coffee pot in the space because there was nowhere to go to the head. they had no Broadway. he would have to go up on the weather deck (01 level?) from berthing or mess deck and then back down into the fire room. the 16' ladder for entry and exit would be so hot they wore gloves when using it. he sailed from Norfolk/Little Creek to Cuba and P.R. mostly with one Med Cruise in 54. they didnt have control for adding feed water. he had a water tender on a half-level at the top of the boiler (one per fire room) who watched the water levels and added new water as needed. he just turned 93, 10 October, and im so proud of what he did.

The main forced draft blowers were 1200lb. steam driven,controlled by a throttle wheel overhead. The N.S.F.O. used for fuel had to be heated and filtered prior to squirting it out the nozzle tips.

[@ZGryphon]

The paper mill where my father worked as an engineer when I was a kid also burned Bunker C in B&W boilers, which probably explains why most of the guys who worked in the mill's steam plant back then were Navy vets. Also, fun fact: it's called bunker oil because in the earliest oil-fired ships, which were converted from coal-burners, it was stored in what had been the coal bunkers.

[@davidjackson8969]

[@ZGryphon]

@@rolandtamaccio3285 Oh, it is definitely that--it's practically tar. The "coal bunkers" thing is just where the name comes from.

[@billhunsinger862]

Oil fired electric generating plants on land also referred the oil as Buncker C. It had to be steam heated in the tanks to pump it into the "power house".

[@lloydevans2900]

Paper mills often run what they call "recovery boilers" to generate the power needed to run the mill itself, though they can sell surplus power to the grid if they want to. The primary fuel for these boilers is what is known in the paper industry as "black liquor". This is a byproduct of the wood digestion and pulping process - the cellulose fibres from the wood are what become the paper, but wood contains more than that: The lignin and other resinous parts of the wood are digested by the alkaline cooking process and are separated out into soapy, oily concoction - this is the "black liquor", though the colour can vary from yellow, through red, brown or black depending on the type of wood processed. Before the 1930s, most paper mills just dumped the black liquor into wastewater, which was not a great practice because it is caustic and toxic. Recovery boilers were developed to actually use it as fuel, which turned it from a waste product into a valuable energy source. There are two reason why a mill would co-fire the black liquor with Bunker C oil: Primarily because some types of wood don't generate as much black liquor as others, so there isn't always enough to generate all the energy requirements for the mill, meaning they need to burn additional fuel for that. But also, in some places the government will provide subsidies for factories or power plants which supplement their energy requirements with biofuels - and since black liquor is classed as a biofuel, paper mills can claim this type of subsidy if they burn a combination of a fossil fuel (which Bunker C oil obviously is) and a biofuel in their boilers.

[@Darwin76]

Excellent tour. One point you missed was that the reverse was often used when the ship was stopped to create a lee. When backing out from a pier, we used the outboard shaft back slow to move some water between the ship and the pier. Also, when working with small boats in open ocean, we would back the shaft on the side of the boat to create some calm water so it would be easier for the gig to approach the ship.

[@cruisinguy6024]

I’m not understanding the second part of your comment about working with small boats. Are you saying that when underway you’d reverse an outboard shaft to create calm water? I’m by no means a sailor but it seems like that would create more turbulent water.

[@Darwin76]

On USS IOWA, we had a procedure to receive a small boat in open ocean (such as at Diego Garcia). First, take a heading to put the wind on the starboard beam -- this creates a lee on the port side. Steam at 2-3 kts to get enough water flow on the rudder to hold a steady heading. Back the port shaft dead slow (with the other three shafts at slow ahead). This creates flat calm water on the port side and allows us to receive a boat when there might be a swell in the sea. These were important boats because they often contained mail from home. @@cruisinguy6024

[@SeanBZA]

@@cruisinguy6024 You are pumping water to the side of the ship, to counteract the forward motion, so the boat comes into what is essentially calm water. The ship would always have some slow forward motion, so that the rudders have control authority, and the ship will not be rocking off beam, so pumping water forward to make a still pool near the midpoint will make transferring and mooring easier, as you are no longer needing heavy lines and bollards to apply pull to the smaller vessel.

[@tomnewham1269]

@@cruisinguy6024At sea small ships would pull in alongside an Iowa class battleship to either offload supplies to the battleship or to top up their own fuel supplies. Iowa’s carried a lot of fuel so were often used to supply fuel to other ships. This is all done in open waters and the ships don’t stop while doing this. Hence the comment about turning the propeller backwards on that side of the ship to reduce wake alongside the battleship so as to make it easier for the small ship to stay on course.

[@cruisinguy6024]

@@tomnewham1269 I appreciate your response. I've seen lots of videos of UNREP from supply ships in open seas and it always seems as if the ships are moving at a good clip. When a shaft is put in reverse to create a smooth patch for a smaller vessel to come alongside what's the forward speed of the ship typically when this happens?

I recall being told that bunker C fuel oil also had the highest BTU content per pound and therefore gave the best economy of the fuel types available at the time. I served as a machinists mate on board the Newport News (Salem class 8" gun cruiser) and the video was a trip 50 years back in time. I spent many hours standing in front of the throttle wheels and learned how to simultaneously spin the ahead throttle closed and the astern wheel open. That might have cut 5 or 10 feet off our stopping distance. Ryan makes a good point about how hot the engineering spaces were. We worked in dungaree pants and t shirts with plenty of exposed skin to collect sometimes serious burns. Nobody knew how to spell PPE back in those days. We drank as much water as we could stand and took handfuls of salt pills. No wonder we all have high blood pressure now. 50 years later I can still remember the smell of the bunker oil, the heat and humidity, the noise (good for a VA tinnitus disability claim) and the pride we felt in doing an extremely difficult job extremely well. Snipes are a rare breed.

Yes!!! Excellent video, thank you. I spent 2 1/2 years in Missouri Engineroom #4, and my eyes were darting back and forth, recognizing equipment from my days of old as you traveled through. 33 Knots was her "classified" top speed; what the Public was allowed to see. Yes, they go faster...how much faster is info I'm not privy to. It was kinda comical though, we'd be pulling back into port at Long Beach, and Civilian boats would come out to meet us and escort the ship in. Just regular people in their private boats, having a good time. We'd be loafing along at 8-10 Knots or so, slowing down for Port entry many miles ahead of time, and still the Civy boats would struggle to merely match our speed heh. Also, we always kept brooms handy, not just for cleaning purposes. If the steam pipes got a pinhole leak, you found the leak by waving the broom handle in front of you. The 600PSI steam has SO much energy, it would supposedly lop off the end of the broom handle like a laser. Happy I never got to test that theory out.

The Gearings had 4 600 lb Babcox-Wilcox boilers and two 30,000 Hp Westinghouse turbines. When we were completely lit off (all 4 boilers) we could do around 34 knots. Man was that hair-raising, to say the least. Those ships were a BT's dream. They only had the stream-powered Fuel pumps in the Boiler spaces. We had all the auxiliary equipment in the Engine Rooms DA, Feed, and booster pumps to maintain and operate on top of the lube-oil pumps for the Reduction gears. All that packed into small engineering spaces on a 390-foot vessel with a beam of 40 feet. We used to call it standing watch in 120, 120* heat at 120 dbl sound. It was deafening and our hearing suffered from it too. I've toured the Midway several times in San Diego. She's another 600 lb plant very similar.

Non condensable gasses are purged through the main air ejector. The DA tank main duty is to store and heat feed water. Also you said the feed water got up to 800 degrees in the steam drum. The water is turned into saturated steam in the steam drum, approx 495 degrees. Then the saturated steam goes to the superheater where it comes out at 840-850. Principles of Naval Engineering (NAVSEA) Page 348 "In modern shipboard steam plants, air ejectors are used to remove air and other noncondensable gasses from the condenser" Been a long time since I was on the Jersey or Missouri, but you can usually find the main air ejector forward of the HP/LP Turbines.

Another (likely) engineer. Hello, friend. He also said the propellers are spinning at approximately 200 rpm. As a merchant sailor, I'm sure the props on New Jersey spin faster than a cargo ship's (around 70-80 rpm at full speed). I highly doubt, however, that they're spinning at 200 rpm. Its probably closer to 120-130 at full sea speed. Edit: It would appear that I was wrong. I did not realize that naval propellers are smaller diameters. This allows them to spin much faster.

M-type boilers are also known as controlled superheat boilers, because the superheating process has separate burners and can thus be fine tuned independently of primary steam generation. On smaller ships, where space and weight are at a premium, you’ll find D-type boilers, aka uncontrolled superheat boilers, which didn’t have separate burners for the superheating process. The late 60’s/early 70’s design of the Knox-class DE/FF I served in had two 1200 psi D-type boilers driving a single engine/shaft. Automatic boiler controls vastly reduced the workload for the BTs-the older 600 psi M-types were all manually controlled, and took a lot of work to operate.

EM2 Ross, Electricians Mate Second Class Petty Officer, USS Ranger CV-61, Aircraft Carrier, Jan 1976 to March 1980, The Navy's First "Enlisted Surface Warfare Specialist". I gave the Engineering portion of Surface Warfare Specialist to officers on Ranger. So, when the opened the classification for enlisted men, I was first in line. Young man, and I am nearly seventy, you did a very fine job with your walk thru explanation of the power plant in this ship. If you were not in the Engineering Dept of this ship, someone wrote you a great script. I found it enlightening to go thru this tour with you. I never had an opportunity to go on a battleship. As I expected the design and layout of the main machinery rooms were very similar to an Aircraft Carrier. The USS Ranger was Naval Distillate also. Carriers are all Nuclear Powered now. Four main engine rooms. We had eight ships service turbine generators, ours were 1500 KW. As you walked thru the spaces, I realized that yes, I could have served on this ship also, if I had had the chance. The USS Ranger CV-61 had 6500 men during deployment to the Indian Ocean, Subic Bay Philippians. We had 600 in Engineering Department. Out of that 600, we had 200 Electrician's on board. Out of the 200 Electricians were about 30 Intercommunication Electricians. They worked on telephones and intercom systems. We had 999 rotary dial telephones on the ship. The telephone system was a three-digit stepper exchange, that's all you could have. My first assignment on board was the lighting shop. This was a group of about twelve Electricians that did nothing but change out screw base light bulb fixtures to fluorescent tube light fixtures, thousands of them. That simple act dropped the entire electrical load onboard the ship by 50%. Then we added a lot of new stuff and brought it back up. I suppose that the same thing would be done now by changing the fluorescent tube light fixtures to LED, Light Emitting Diode lights. I recently got involved in a conversation about "Bug Juice" on board Navy ships. The person was commenting about our "Bug Juice Machines" serving something to drink on board Navy Ships. I waited until the person complete his explanation of what it was before I offered a rebuttal. In out "Mess" areas of the ship, cafeteria areas, they would make up large containers of Kool-Aid. All the fresh water on board ship what distilled from sea water. If you have ever drank distilled water, you would know that it is tasteless. It is not very pleasant to drink. Oh, it makes good coffee, but you must flavor it to get anyone to drink it. Ok, just one more. During my time onboard the ship the ships services folks had an opportunity to install a single video game, Pac-Man. It was installed with the games costing twenty-five cents. Since they were not allowed to make money on the proceeds from the game, they told us that all proceeds would go towards purchasing more machines. Within six months, they had filled the arcade room full of video games, about forty machines. About three months later, they had to make all the machines free. Thank You for allowing me to comment like so many others have done below. If you have a family member that is a Veteran, please take the time to hear some of his stories. Most Veterans have stories to tell and some day they will not be around to tell you. My father was a World War II Army Veteran. He serviced in Italy during the war as a foot soldier on the front lines. I respectfully listened to what he wanted to tell me. I knew that some of the things he did, he did not want to talk about.

[@ericbowen650]

Hi, Ryan. Pretty good walk-through, but you've still got a few things to bone up on before you sit for your EOOW exam. For one thing, that blue line dropping down from under the DFT is actually water going OUT of the DFT to the feed booster pumps, which are designed to run cavitating to provide net positive suction head to the main feed pumps, which will NOT run cavitating. In merchant ships with plenty of space the DFT is elevated some forty to fifty feet above the feed pumps rendering the feed booster pumps unnecessary, but obviously that's impractical on a battleship. Water coming into the DFT is pumped by the main and auxiliary condensate pumps which take suction out of the condensers and send the condensate back into the system. Also, you got the throttles exactly backward in the engine room. The throttle wheels are, first and foremost, valves...righty tighty, lefty loosey. So you turn the ahead throttle wheel counterclockwise to open the nozzle valves and accelerate, and clockwise to shut the throttles and slow down. Also, the astern turbine is actually a separate turbine, but placed on the same shaft as the low pressure turbine blades. The steam doesn't "flow backward" through the turbine; rather, the astern throttle is opened to admit steam to the astern elements placed on the forward and aft end of the low pressure turbine rotor, and that develops the power to spin the shaft in reverse. The two large steam lines coming into the low pressure turbine from the overhead are the astern steam lines, while the large pipe coming from the high pressure turbine to the low pressure turbine is the crossover. And the steam going into the condenser is not at "zero psi" (or, at least, it better not be!); it's at well below atmospheric pressure. To squeeze every possible horsepower out of the steam flow, the steam keeps expanding all the way (and increasing in volume tremendously) all the way down to the condenser pressure of about 29" of mercury below atmospheric. Fun Fact: At full power the high pressure turbine expands steam from 600 psig down to about 55 psig, while the low pressure turbine continues the expansion from 55 psig down to 29" vacuum, or about negative 14 psig. But (at full power) the low pressure turbine develops more horsepower than the HP turbine, due to the tremendous expansion in volume as the steam drops below atmospheric pressure. Look up and study a "Mollier Diagram" for the straight skinny. Otherwise, pretty good job; you're getting there!

[@FightUni09]

I caught that too about the DFT. But the condensate usually passes through the steam jet air ejectors and first stage heaters before entering the DFT which is a direct contact heater with auxiliary exhaust heating. There would be a small vent on the DFT blowing steam and whatever non-condensibles it could drag out to the outside atmosphere. I gave him a pass on the engine controls because he never actually ran them. I'd bet that the astern turbines are velocity compounded impulse stages (maybe 2 stage?). Wondering if there is a lube oil gravity tank with a bullseye to the gears?

[@lawrenceleverton7426]

They probably used Curtis Staging as the Astern Turbine. Much more durable in case of water droplets in the steam. "Mollier Diagrams" brought back memories of things you knew and forgot from 30 years ago. All I remember was it was a hot hot hot place to work. And not many peeps strolled by to say hi.

[@ericbowen650]

@@FightUni09 Correct about condensate to the DFT; I was simplifying. On the Missouri, IIRC, the astern elements (pair) were single-stage velocity compounded Curtis stages with three rows of moving blades. And no gravity lube oil tank on an Iowa-class.

Love the details here! I would really enjoy hearing more about the fuel systems, both how fuel gets to the boilers (does it need to be pre-heated, since it’s more of a pudding, and if so, how does it get out of tank, are there tank heaters?), as well as how fuel is stored, and how it’s refilled.

[@kevincrosby1760]

Bunker C was the thick black oil that needed to be pre-heated to be able to get it to flow through the burners. I believe that there were tank heaters, as well as local heaters near the boilers. As Ryan said, the boilers were converted to Navy Distillate (DFM) fuel during the 80's upgrade. DFM is very close to what a residential oil furnace would burn. As with any liquid, fuel is stored in tanks. To take on fuel you either go pierside at a fuel pier, or receive fuel during an Underway Replenishment (UnRep) at Sea. Of the two, UnRep is actually quicker, as the replenishment ship is quite capable of transferring fuel at volumes and pressures that would make the civilian workers at the fuel pier crap themselves and run for the hills. Life kinda sucked for the replenishment ship, as they had no choice but to take on fuel at a fuel pier. When your tanks hold 5 million gallons of DFM and 2.5 million gallons of JP-5, you WILL be there for a while...like 24-36 hours.

[@richcruse2689]

Actually they have low pressure steam systems to heat the old bunker fuel, it’s called “steam tracing piping”. It was in each fuel tank and attached to all the fuel piping. You can still see it on the fuel lines.

[@kevincrosby1760]

@@SeanBZA that's a nice theory, but I never saw it happen in practice. We were on 4-section duty, which means that at any given time, 1/4 of the crew was on duty and could not leave the ship. This was normal in-port Cold Iron routine with everything shut down. You're not going to shut everything down and go Cold Iron for a 24-36 hour refueling. That means Engineering is running pretty much fully crewed. Besides, you're not going to be able to pull enough power from a Shore Power connection to run fuel transfer pumps to keep the ship in trim as you are taking on fuel. "Taking on fuel" brings us to the guys in POL, who are responsible for all things fuel-related. They are also running a full crew whenever fuel is being taken on. Since you now have Duty Section + 2 departments working, the galley isn't going to get away with 2 guys on duty, so they are stuck on board as well. In short it all snowballs, and most of the crew ends up stuck on board. It should also be mentioned that M-F 7-5 are working hours, and EVERYBODY is on board.

Marine diesel technology was not capable of producing this kind of power back then. Today, you can get low speed marine diesels up to 100,000hp or more. and since they are low speed, there is no red gear, they are direct drive, which saves weight (not that the engine is light, but you don't then have the EXTRA weight of the reduction gear) and cost (initial and maintenance). But you are correct, at the time, this complicated steam power system produced the most power for its weight and operating cost.

[@josephpadula2283]

I Think the small electric forced draft fans were put in only on navy ships when the switch to light fuel happened . Merchant marine never switched . We joked giving a steam boiler designed for bunker light diesel fuel is like giving fine 12 year old scotch to wino! On light off the air fuel ratio even with smaller burner plates, hole size, was too high and the much more volatile gasses collected in the cool uptakes . The fans could not be slowed down enough of the dampers shut for the slow warm up needed. We had many boiler explosions . A boiler inspection device BID was used later to check for diesel pooling in the furnace floor also causing flare backs not normal with bunker. It was a periscope with a light shoved into the burner register to see the floor. The worst part was the Merchant steam ships Never cleaned the tubes even with bunker C frequently like the navy did neither did any shore plant! It was a Navy tradition left over from God knows when perhaps coal clinker days!!! We water washed the boiler fireside’s annually instead . I often think of the poor BT’s in hot just shut down boilers doing the unneeded work because the Engineering officers were only Navy boiler trained and did not see shire plants or read outside non Navy reports ! How many BT s did not reenlist due to the foolishness before they switched ? How much extra money did the Navy spend buying F-76 rather than bunker c/ NSFO!

AWESOME Video, Ryan! You do an amazing job explaining these modern marvels. Thanks so much for sharing your gift and your love for all things mechanical. Take care, God bless!

Nothing to be ashamed with the old videos. Everyone has to grow into their shoes. I think they were plenty informative enough. Bout the only thing i can "gripe" (if for no other word fitting, really) is the sound quality, but you've sorted out neatly. I often go through the old videos if something peaks my interests in a newer video to supplement the information.

Ryan, you are a graduate of the "School of Hard Knocks" in videography. Now to work on your Masters and Doctorate!

ChiefSamanski, finally got around to my neighborhood, MM, CVA. Spin me back down the years! You did a great job of it, I can almost smell the oil/steam blend, bilge-water, too.

[@adamdubin1276]

The water droplets can also cause major issues in the boiler itself such as eroding and corroding the tubes leading to leaks and because the water droplets are incompressible if there is a significant build up they can cause ruptures or explosions... unlikely to happen in a more modern design such as the M-types that New Jersey was fitted with (especially if well maintained) but was a major concern in the early days of steam power.

[@terrybaird9532]

The tubes carry water to and from the water drum to the steam drum. I think you may be talking about water quality in the boiler. High TDS, water hardness can leave silica on the inter tube walls and can leave to tube failure. Water tube boilers are not prone to explosions as were fire tube boilers of old.

Do you remember your 3 endpoints of boiler operation in order of severity? Brings back memories for me!

I am in awe of this magnificent machinery and the crew which operated it.. Thank you, Ryan, for your excellent explanations.

I thought the turbines would be bigger! Amazing power from that setup. Modern jet engines are just recently making 50K lbs of thrust and are similar in size it would appear!

[@jakem7838]

The LM9000 gas turbine makes 98000+ hp. Pretty impressive.

Another great video. Dont sell yourself short on the old videos, its all part of your journey too.

It amazes me that this ship was designed and built with no computer. The skill of the tradesmen who built that ship doesn't exist in the world today.

[@johnharlow486]

Don’t be silly, tools and techniques have improved. If we had to continue with inefficient drafting techniques we would not have improved so far that battleships are completely obsolete. But yes extremely impressive for the time.

Every single thing in the world was originally built with no computers. And those things were all mechanical too - no electronics either.

That is one hell of a lot of power. Close to double the output of the current worlds largest marine main diesel engine . Engineering focus and footage of the systems actually being manned were excellent. Thank you!
