I don't agree with UA-cam hiding Dislikes; 741 Likes, 4 Dislikes, 2024-09-24. Just so you know what to expect of this Video. So here's a quick FAQ that I saw in the first Comments popping up: Where is the Ship located? Mostly at the Övelgönne Museum Ship Harbour in Hamburg-Neumühlen, Germany. It sails from early May until mid September, which also includes visiting other Ports along the German North Sea and Baltic Sea Coast. How is Feed Water produced? Not at all; there is no Desalination Plant because the Stettin was never intended for Voyages longer than a few Days, so Feed Water is just bunkered from Shore. How is the Ash disposed? As of now, it is dumped overboard with an Ejector, but that might change in the next Years due to enviromental Concerns. Hence I don't show the Ejector in the Video, I actually did initially but removed it to keep the Video under 25 Minutes. Why is Steam Expansion divided over three Cylinders? Steam cools down as it expands in the Cylinders, hence the Cylinder has a Temperature somewhere around the middle between the hot Steam coming in and cold(er) Steam going out. Dividing the Expansion over multiple Cylinders reduces this Temperature Gradient, and thus less Heat is wasted on "heating" the Cylinder when hot Steam enters it. Is the Crew paid? No, all unpaid Volunteers, just like I do on the Museum Ship Cap San Diego, which is located in Hamburg too. But isn't the SS Badger larger? Yes, that's why I mentioned it in the Video with the Explanation that it has Mechanical Stokers.
Its 13 now, but i have no idea why. I absolutely love your videos. Seeing old school technology still goin well. Love, sweat and tears. Seeing the steam motor providing power was honestly suprising, i would have thought that for at least "modern" AC power they would use a diesel genset, but no, this old girl is still entirely steam driven. An absolute work of art.
@@colinsmith6340 Nope, still at 2; these Browser AddOns are not that accurate and mostly exaggerate.

I have only operated some, and seen many small or replica model steam engines, just to in awe have _some_ understanding of how this large, complex and brilliant machinery works as numerous interdependent systems. Co-operated by so many skilled individuals in unison! My grandfather (mom’s dad) was a senior machinist on large ships from ca 1937 until 1966, and passed away that year as I was about 7 months old. This video brought me closer to what he may have experienced than any presentation I’ve ever seen. Kudos to all who carry forth the practical knowledge and sheer willpower to keep Stettin a monument to what once was leading everyday technology for trade, travel and sadly also our world in conflict. I’m deeply moved by all of the above. My deepest thanks for sharing, and my greetings from Norway. 💛
This is an excellent, informative video of older steam technology before its pinnacle. Thank you for a well thought, educational video with supporting annotations!
Brought back memories, of when i worked as a fireman, on the harbour Tug's, in Cape town 1960's. The only difference is, the ash was loaded into hoppers at the side, with a lid on it, and then discharged into the sea, by water pressure.
That's how it's done here too. I actually recorded that, but didn't use the Footage. Reason is that it's an ongoing Discussion if dumping Ash overboard needs to stop due to enviromental Concerns, meaning to say it may change in the next Years.
Good video and first-class explantion. I was a (steam) marine engineer during the 60s and 70s and I had one steam recip ship in the early 1970s. At high revs (76rpm!) it threw out oil everwhere and I got soaked without fail! It was great experience though, which I wouldn't have missed, before going back to turbine ships afterwards. Thanks for posting such great memories.
How amazing footage and clear description of quite a complex set up. Triple expansion engines were the zenith before turbines. This should be compulsory viewing for all kids(and big ones).thank you.
A wonderful film with detailed explanations of all parts and their functions Thank you very much. The perfect addition to a visit to the ship. And as a lucky Hamburg resident I can do that in style by taking ferry 62 from Altona to Neumühlen. By the way, the elderly still say "take the steamer" when they want to go by ferry
Makes me wish I didn't live 500km from the nearest large body of water (Lake Superior) and 1500 from the nearest one that could be considered part of an ocean. :) We don't get cool things like this where I live! Thanks for the tour!
I didn't explain why though, because it would have made the Video too long. Steam cools down as it expands in the Cylinders, hence the Cylinder has a Temperature somewhere around the middle between the hot Steam coming in and cold(er) Steam going out. Dividing the Expansion over multiple Cylinders reduces this Temperature Gradient, and thus less Heat is wasted on "heating" the Cylinder when hot Steam enters it.
@@Genius_at_Work Also the size of a single cylinder required to fully expand high pressure steam down to (or below) atmospheric pressure would be enormous, and difficult to start (maneuvering). Much easier to do it in stages with cranks at different angles on the crankshaft for smoother power impulses and easier starting...
Sehr interessantes Video. Ich bin Maschinenmeister und habe so ein Einblick in Schifffahrt/Schiffe. Man sieht dass das Video von einen mit Dampf Erfahrung gedreht wurde. Sehr gut. Sehr interessant.
She might be the largest "museum ship" but Badger is a much larger ship in regular service on Lake Michigan. I've had the pleasure of a working visit in her engine room.
Oh how nice :) I planed to travel from Kiel to Lübeck with the Stettin, to see the Setttin from inside, but sadly my bike was stolen this day so i cancel it . THX that I can see what i ve missed. By the way look for the "Start eines U boot Motors aus dem 2. Weltkrieg Schiffsdiesel "
Make sure you keep the ash from going underneath the stoker plate. Bilge sea water and ash corode the hull floor plates, transverse and longitudinal stringers, boiler mount and inner hull plate. When the vessel is slipped the weight can be too heavy and boiler mount breaks through the bottom hull. Always a good place for the engineer surveyor during survey to hit hard with a hammer or these days a thickness tester.
Season is from early May to mid September, although not always in Hamburg. The outside Views were recorded at the 2022 Flensburg Steam Fair, the onboard Footage on the North Sea between Büsum and Cuxhaven.
Living history so worth while preserving for future generations. The guys in the engine room should be wearing hearing protection or their hearing will screwed like mine from working in heavy engineering & ship repairs.
The curved bars on the eccentrics is refered to as "Stevenson reversing gear" Had this on the river class frigate HMAS Diamantina now a museum ship in Brisbane Australia. Sadly a non runner.
I was US Navy 1968-74, reactor operator on ballistic missile nuclear submarine. Very quiet in the engine room at anything less than a full-bell (steam turbine main engines, steam turbine electric generators). First thing I notice in the vid is the noise. Become very noise sensitive living in a submarine. Noise tells the enemy where you are. ---- Coal took the world out of the middle ages into the industrial revolution. A miracle fuel (inexpensive and high energy density). But for coal there would be no trees left in Europe.
It's a really quiet Engine Room, by Civilian Standards where Noise doesn't relly matter (yet; I expect that there may be coming Regulations regarding that in the mid-Future, to protect Whales). It's quiet enough to allow Conversation without having to shout, like on almost all Piston Steam Engine Ships. Oil-burning Boilers are quite loud though, but most Ships have separate Boiler Rooms and most German Steam Ships burn Coal. Even the 1962 Cargo Ship Cap San Diego, where I volunteer as Mechanic has a Diesel Engine quiet enough that you don't need Hearing Protection in most of the Engine Room. Reason is that it is a 80 RPM Two Stroke Engine and has small Turbochargers with just 0.1 bar Scavenge Air Pressure, with modern Engines of 2-3 bar, the Turbochargers become very loud as soon as they build up Pressure. The Ships that I work on for a Living have Pitch Propeller Propulsion, meaning to say the Engine always runs at 440 RPM and is very loud regardless if the Propeller is set to Pitch 0 or Pitch 10. Btw. I am working on a Video about the first French Nuclear Submarine Le Redoutable, which is preserved in Cherbourg and to my Knowledge is one of only two in the World where the Engine Room is open for Visitors, the only other one is the first Soviet one in St. Petersburg. The Reactor Room has been replaced by just an empty Section that with a Diashow of how it was turned into a Museum, unlike in Russia where the two Reactors were replaced by Replicas, but my Chances of getting there are slim to none. Anyway, what I am up to is that I was a little surprised by the apparent Absence of a smaller Marching Turbine; the Redoutable Class is powered by two identical Turbines that drive one reduction Gearbox. The Turbines didn't seem like a Turbine Set (consisting of HP, LP, Reversing and possibly a smaller Marching Turbine) to me but literally just one Turbine. Not bothering with a Reversing Turbine seemed logical, because using the Electric Motor for Manouvering made Sense to me. But given that Missile Submarines usually creep about Dead Slow (to my Knowledge), I would have guessed that a smaller Marching Turbine is way more efficient than running the large Turbines at awfully slow RPM. Because Le Redoutable is just on static Display (obviously), I must resort to voicing over that Video which already takes me ages as I'm not a very good Speaker. I only took Pictures of the Engine Room, because it was so crowded that recording Video was impossible without someone walking into Frame all the Time. I guess I'll give it a go to show myself speaking, even if it means possibly hundreds of Takes as I am a very bad Speaker, but I'll have plenty of Time when I'm at Sea again.
Btw. here's the two louder Diesel Engines that I mentioned: Cap San Diego: ua-cam.com/video/rZkW4A_cOfU/v-deo.html The Ships where I work: ua-cam.com/video/xkp_T-DSA-s/v-deo.html The latter Video is not public yet, and probably won't be for some Time.
Was that a coffee pot in the scene where the operator was filling the cylinder oil? And, the small highspeed, engines - were they also VTEs? How do you make feed water? Do you have some sort of distillation plant or evaporators? Thanks! GREAT video!
There is no Desalination Plant, because the Stettin never was intended for Voyages longer than a few Days and Feed Water was just bunkered from Shore. Regarding the other Questions: These are Oil Cans, and what do you mean by VTE?
I'm good with mechanics, but who figured out where all of this fits inside the engine room? I wonder how often during the building, was it said, "Hey, we've go to couple this pipe here with that thing. I need another five feet of 3" pipe, a 90 and 60 degree elbow, a coupler and a reducer to one inch..... yea, that's enough."
Shipbuilding used Models for that until CAD came up. Pretty much every Marine Training Facility I ever visited (Rostock, Travemünde, Flensburg, Elsfleth) has such Models on Display, the Hull is made of transparent Plexiglass and all Pipes are painted in the typical Color-coding Scheme.
Excellent video. We have done a little better, apart from a couple of museum ships, the last sizeable (75kt) coal fired ships in Australia were for Queensland Alumina - had 5 steam ships running Wiepa-Gladstone 1981-2012. Machinery 2 automatic chain grate boilers plus a single turbine about 8MW. Cylone exhaust cleanup. Gave great service. The first one was retired last after spending a couple of years as a collier.
Your HP and IP are piston valves, only the LP has a slide valve as shown on the diagram and cylinder tops. It is a Triple Expansion not a 3 cylinder triple expansion, if it was a two cylinder it would be a Compound Expansion. Single cylinders are usually pumps called simplex pumps or expansion. A FD fan engine could be single or compound steam engine, steam dynamos are often Compund engines.
I know that, but just called all of them Slide Valves for Simplicity. And there were Triple Expansion Engines with four Cylinders, because with larger Engines the Diameter required would have become too large for one Cylinder, so large Engines had two Low Pressure Cylinders. Similar to how many Steam Turbines have multiple Low Pressure Turbines because the Blade Length would become too large; e.g. have both Swiss Nuclear Powerplants Turbine Sets consisting of one High and three Low Pressure Turbines. The Genset Engine has three identical Cylinders, because these Spilling Motors are modular like many Industrial Diesel Engines. Spillingwerk builds them to this Day, mostly for Applications with dangerous Atmosphere and abundant Steam, such as Refineries or Chemical Plants. And the Engine drives a Generator; Dynamos are excited by Permanent Magnets and Generators by Electromagnet Coils. The latter allows controlling Voltage independent from RPM, which is vital for synchronising Generators to the Grid.
Germany really likes its coal. Not lignite in this case of course. In fact a huge proportion of the German electricity grid burns lignite which I think is the highest proportion in Europe. (the renewable figures are a bit fake). However one interesting coal powered ship is not going to make any difference and is well worth preserving. Looks great.
There actually are 10+ Coal-burning Steam Ships in Germany, although none of the others are anywhere near as large as the Stettin and all but one are Volunteer-ran Museums too. The only commercial one is the Paddle Steamer Diesbar in Dresden, but it sails rarely and the Operator mostly relies on its other Oil-burning Paddle Steamers.
Exactly, but I just called all of them Slide Valves for Simplicity. Slider-Type Slide Valves are impractical for higher Steam Pressures because they are sealed by Steam pushing the Slider onto the Rail, which would be too strong with higher Steam Pressures making it too hard to move the Slide Valve. This being forced onto the Rail has the Advantage that Sliders just get pushed off the Rail if the Cylinder gets hydrolocked, turning them effectively into a Safety Valve. That's why Sliders are better than Pistons for the last Expansion Stage, where Condensation may already occurr.
It must take real commitment to volunteer to stoke the boilers. Are the crew paid or are they all unpaid volunteers 🙋♀️ 🙋♂️? I think that shaft at2:40is a fresh air ventilation shaft, not a boiler uptake
I was on the last all guns Steam Destroyer the USS Hull 1200 lb steam 960 ° superheat we would climb up on top of the boilers and gag the safeties chain them shut for full speed wartime simulated runs the whole damn ship would Shake 30 or 40 ft rooster tail to the gods of steam
2200 HP, as stated in the Video. But it only runs anywhere near that during the Steam Ship Race of the Flensburg Steam Fair. It actually is fitted with an Electronic Device that reads out Propeller Shaft Power and Torque (Hoppe Shaft Power Limiting System), you can see the Sensor Ring in the Footage of the Propeller Shaft. When the Engine was running Dead Slow, it uses as little as 100 odd HP.
I don't agree with UA-cam hiding Dislikes; 741 Likes, 4 Dislikes, 2024-09-24. Just so you know what to expect of this Video.
So here's a quick FAQ that I saw in the first Comments popping up:
Where is the Ship located? Mostly at the Övelgönne Museum Ship Harbour in Hamburg-Neumühlen, Germany. It sails from early May until mid September, which also includes visiting other Ports along the German North Sea and Baltic Sea Coast.
How is Feed Water produced? Not at all; there is no Desalination Plant because the Stettin was never intended for Voyages longer than a few Days, so Feed Water is just bunkered from Shore.

It must be utilized to teach and also be preserved.
Great explanations. It's nice to see videos with good explanations taken by someone who knows something about which he is shooting.

Excellent explanation of the machinery, easy to understand! I love icebreakers and I love steam engines!
In winter 1962-1963 she was ice breaking on the river Elbe, we were frozen in the port of Cuxhaven for 6 weeks, extreme cold weather

Brilliant video as always
Great explanation of how the compound engine works...I am building one at the moment., they are quite complicated compared to industry steam engines.
Make sure you keep the ash from going underneath the stoker plate. Bilge sea water and ash corode the hull floor plates, transverse and longitudinal stringers, boiler mount and inner hull plate. When the vessel is slipped the weight can be too heavy and boiler mount breaks through the bottom hull. Always a good place for the engineer surveyor during survey to hit hard with a hammer or these days a thickness tester.
This is an excellent video! Wish I'd seen this instead of the Reeperbahn! Have to visit again.

I've initally had that "Stephenson's Link" in the Video, but removed it when I cut a few Things out to get the Video below 25 Minutes.

Very quiet in the engine room at anything less than a full-bell (steam turbine main engines, steam turbine electric generators). First thing I notice in the vid is the noise.

There is no Desalination Plant, because the Stettin never was intended for Voyages longer than a few Days and Feed Water was just bunkered from Shore. Regarding the other Questions: These are Oil Cans, and what do you mean by VTE?

I think some bulk carrier ships on the Great Lakes remained coal powered into the 1950s, maybe beyond?

When the Engine was running Dead Slow, it uses as little as 100 odd HP.
