There are folk on KZfaq that dislike everything, take no notice of them. It is a well known fact they dislike their parents as well ! It is difficult to describe how beautiful a large steam engine is in action, so peaceful to watch.

@@vulgivagu If I didn't like Dislikes, I wouldn't bother telling how much of them there are. People having valid Reasons to not like my Videos are welcome to leave a Dislike and I can tell a few Things to not like about this Video; e.g. you can't see anything in the Boiler Room (the Light is really weird there) and the high ISO Speed often causes a bit of Image Noise (the entire Engine Room is quite dark as well). If People tell me what they don't like, I improve these Things if I can and want to. Take that Tandem Compound Steam Engine Video for Example; someone complained about the Explanations and I told him he'd be better off watching the Videos that just show the very same Engine without anything else. IMHO I'm filling a bit of a Niche with explaining how these Things work. Btw. I've got a Voiceover Video coming up, explaining a Paddle Steamer Engine in the Lucerne Transport Museum in Detail, and a Video of the B&W No. 2000 Double Acting Two Stroke Diesel in the MAN Diesel House Copenhagen, which will be similar to this and the Tandem Compound Video. I can't really tell when I'll upload them tho, because I'm a terrible Speaker who needs numerous Takes for an acceptable Voiceover, and because I couldn't record enough Footage in Copenhagen so I have to travel there again. Oh yes and Steam Engines of that Size aren't as relaxing as they may seem. That Engine Room is significantly louder than it appears in the Video. It's still nowhere near as loud as Diesel Engines would be, especially turbocharged ones.

750 tons of coal titanic

This is really cool. This would be the largest operational hand fired steamship in Europe, but not the largest operational coal fired steamship. That distinction belongs to the SS Badger that runs daily on Lake Michigan. The Badger is nearly three times the size, with two four cylinder compound unaflow reciprocating engines.

@@Art_Thompson That's sort of what I meant with that; I knew about the Badger when making this Video but wrongfully assumed it was fired by Coal Dust. Because it has an mechanised Stoker System, and the Hand-fed Boilers of the Stettin are closer to the Titanic-Image most People have when reading "Coal-fired", I'm going to stick with "largest Coal-fired Steam Ship in the World" in the Title for future Videos about the Stettin (there will be at least one). "The largest Coal-fired Steam Ship at Sea" just is a much better Title than "The largest Steam Ship with Hand-fed Coal Boilers at Sea". Mind you, except for that Video (which will show the entire Ship but without Explanations), I will label it correctly if I ever re-shoot this Video with a better Camera. The Image Quality really sucks, especially in the Boiler Room.

The Stephenson Valve Gear actually is pretty simple once you understood it. Tomorrow, I'm going to upload a Video of a stationary Steam Engine with Sulzer Valve Gear which is a lot more complex but works great with a Flyball Governor to keep the Engine at a constant Speed.

You CAN understand it. People less educated than you MADE these. Never doubt your own ability to understand. Society wants you to believe you are less than you are. Do you want to know how I know that? Because you are HERE and you have life! Don't ever underestimate what you can do or know! I lived most of my life doing just that, being humble. I can't begin to tell you the things that have happened because I learned We as people are born into these deceptions.

@@rdallas81 Very true, thanks for the reminder. The way things are going we might be back to steam power anyway?

@@Peranaworthal Highly unlikely, except that almost all Thermal Powerplants use Steam. The Laws of Thermodynamics limit their Efficiency to about 45%, perhaps 50. "Steam Power" like in this Video is significantly worse, because it is nowhere near the Pressure and Level of Superheating of a modern supercritical Steam Turbine Plant. There are some Niches tho, e.g. the Ferries on Lake Zürich, which may be converted from Diesel to Steam in a few Years. Steam would be supplied from a nearby Incineration Plant and stored on Board for the relatively short Passage over the Lake. The Concept involves Steam Motors like the one you can see at the End of this Video tho. Another Concept is COGAS (Combined Gas and Steam Turbine) Propulsion from Ships, similar to Combined Cycle Powerplants. I've made a Video about that before, although I'm probably going to replace that Video by an improved Re-Upload in the next Months. You can find either the old (now) or the new (maybe later) Video there: kzfaq.info/get/bejne/lchod7x1nd64dYE.html

@@Genius_at_Work Thanks for the reply, going to look at the link now.

That's why the Stettin was built with a Steam Engine, even though Diesels were fairly common by 1932. An Icebreaker must be manouverable, so a quickly reversing Engine is a great Advantage. Modern Icebreakers have Pitch Propellers or Diesel-Electric Propulsion for that.

How long do turbine engines need in order to engage the astern turbines

@@Genius_at_Work Could a larger steam engine be reversed this quickly? Titanic took quite a while to be reversed.

@@therandomytchannel4318 Large turbine powered ships have separate turbines for ahead and astern. IIRC even separate propellers. Anyone correct me if i'm wrong.

@@falconwaver totanic could only reverse the compound engines, not the middle propeler with the turbine, reversing them might have also taken longer as stettin was specifically built for good maneuverability. But mostly its just the immense mass at speed

My Channel "surged" from July-October; I only passed 1000 Subscribers by early February. Ever since I passed that Monetisation Threshold, I don't care too much about Subscribers, as they are pretty much irrelevant today and the KZfaq Recommendation System works more based on Viewer Preferences rather than Subscriptions. The only Reason for me to still care about Subscribers is that it is a Number that makes me look "good" when requesting to film somewhere; e.g. did I have to get Permission for both my Swiss Steam Ship Engine Room Videos. Other Examples are two 90-100 Year old Hydro Power Stations in Germany and operated by the same Company, or a V16 Engine on a Diesel-Electric Locomotive. I'm still waiting for Replies from both of these but it's probably futile now almost a Months after I wrote them. One rejected Example would be four V20 Engines on a High Speed Ferry, where ISPS prohibited me from even taking Photos.

I was on some type of retired boat in Halifax, forgot the name of the boat but we got to see the engines and boiler areas. Nothing was running, no steam or any water but the engines looked pretty similar to these, this was 1995 lol

Thanks. My "Tandem Compound Steam Engine"-Video (linked in the End Screen) has a more in-depth Explanation about Compounding, although I explained that in the Comments to keep the Video short. It's all about Temperature Gradients. Regarding your Sydney Anecdote: Hamburg may just have the most operational Steam Ships (and Museum Ships in general) in one Place worldwide; there are at least five Steam Ships, two Cargo Ships from the late 50ies/early 60ies (one of which is the largest seaworthy Museum Ship in the World) and a Number of smaller Diesel Ships preserved there, all fully operational. I've been looking a bit about what Things I could make Videos of in Australia, as Australia is high up on my Bucket List once Travel is possible again (and I have Time+Money to do so). All I found so far are the Echuca Paddle Steamers and the Puffing Billy Railway, especially the Garrat and Climax Locomotives there.

Theoretically yes. IIRC, there was some kind of minor Incident recently, that may have put her temporary out of Operation again.

That's sort of my Concept. I always put in detailed Descriptions on how Things work and try to keep the original Audio wherever possible. I only do Voiceovers if there is no Audio or unpleasant one (especially too much Wind Noise), partially for the Reasons you stated and partially because I'm a terrible Speaker and want to avoid Voiceovers wherever I can. My Channel is "hibernating" right now because I don't have much to make Videos of right now, but I have some pretty cool Things coming up in May, e.g. a Video similar to this one but of a Two Stroke Diesel Engine on the Museum Ship Cap San Diego ( the largest seaworthy one in the World to be precise). I hope I can resume uploading Videos earlier tho.

I think this engine is a man! So it speaks for HIMself!

That's one of the Reasons why the Stettin was built with a Steam Engines, despite Motor Vessels being fairly common by 1932. A Steam Engine can reverse much quicker than a Diesel, making the Ship more manouverable. That's a major Advantage for an Icebreaker.

I found them particulary intersting as well, although they're very common. I know only one Steam Ship without Steering Gear, and it's a really small one but turning the Rudder by Hand already is reall hard Work. The Steering Gears vary slightly in their Layout, but I'd guess that the Control Mechanism works fairly similar in all of them, and all use Chains to move the Rudder. You can see them in many of my Steam Ship Videos. Larger Steam Ships (that are preserved static out of Operation, if preserved at all) had a Bevel gear attached to the Rudder Shaft, so it gets turned by the Steam Engine Crankshaft directly without Chains in between. The Hydraulic Steering Gears of Motor Ships are intersting too though.

Little Addition: I forgot that most Swiss Steam Ships originally had no Steering Gear, but all of them were refitted with modern Hydraulic ones over the last 60 Years.

@@jonathanparle8429 If just the Linkage to the Wheelhouse broke, the Steering Gear could be operated locally according to spoken Commands from the Bridge. Some smaller Ships also have an emergency Hand Wheel with a huge Gear Ratio attached, to turn the Rudder by Hand if the Steering Gear failed completely. But this becomes impractical even with fairly small Ships, as turning the Rudder just takes too long because of the according Gear Ratio. Hence modern Ships must have two independent Stearing Gears for Redundancy Reasons.

Thanks; luckily I had more than enough Time for filming. A few Weeks later, I uploaded a Video of a stationary Steam Engine in Switzerland, but had just about 30 Minutes for recording. The Difference really shows when comparing the Videos. At least I got that Video informative too: kzfaq.info/get/bejne/rbqKp7ukkq7YhGQ.html

One of the beauties of steam ...

The Stettin was still active back then; it was decommissioned in 1981. Stokers still being paid to shovel Coal as late as the 1980ies seems a bit ridiculous, but the Stettin was owned by the German Government, which is know for keeping ridiculously outdated Tech in active Service. A Friend of mine works on a German Navy Tug Boat, which was built in 1961 and the only Upgrades it saw since then is the Installation of GPS, AIS and ECDIS on the Bridge. Everything else is like a Time Machine back to the early 1960ies.

Thanks, but I'd guess this is a little too specific for any High School Class. If it wasn't for my Personal Interest, I would have heard about the Steam Cycle for the first Time in Marine Engineering School. Even that is more general Information on the Steam Cycle and not so much about all the Machines that you can see here; more like calculating the (theoretical) Power and Efficiency Figures of the Engine from the given Temperature and Pressure Data. Little Edit: I've got a very similar Video to this one coming up in May, but about a Two Stroke Diesel Engine on the Museum Ship Cap San Diego.

I've got another one of the Steam Engine on a Swiss Paddle Steamer. It emphasises a bit more on the Steam Cycle, and also shows what a Steam Engine in commercial Operation looks like today; the obviously are some minor Modifications to make it more economical.

Steam Turbines are pretty dead except for Nuclear Ships and some older LNG Tankers (before Diesel Engines could burn the Boil Off Gas just as well as a Boiler). Steam Turbine Ships lloked really intersting to me when visiting the HMS Belfast though, too bad no such Ships have been preserved operational, as Water Tube Boilers are very expensive to maintain. There are three Victory Ships preserved in America, but they haven't sailed in Years because of Boiler Problems and I'm not convinced they'll sail again, at least in the forseeable Future. Old Diesel Engines are really nice too though; see the Video in the End Screen. The other Video in there is worth watching too, regarding what you said about the Waverley. I always found the Swiss Paddle Steamers fairly quiet, regarding the Noise from the Paddle Wheels.

@@Genius_at_Work There are several steam turbine freighters still running on the US Great Lakes, although several others have been dieselized in the last few years. The ones still running have automated controls.

WIP, but I don't have much to make Videos of right now, like every Winter. I've got a Video of the Double Acting Two Stroke Diesel Engine in the MAN Diesel House Copenhagen coming up in April, the Two Stroke Marine Diesel Engine on the Museum Ship Cap San Diego in May, and a "How to fire up a Steam Ship"-Video on the Steam Ship Alexandra in Flensburg some Time this Summer, probably July or August. More Stuff that I can't assure 100% yet include an almost 100 Year old Electric Locomotive, a 130 Year old Hydro Power Station and starting up a 60 Year old Cargo Ship.

The Image Quality could be better though, especially in the Boiler Room. My GoPro doesn't work that well in such Low Light Conditions, although the Light in the Boiler Room is really weird anyway. There also is a minor Mistake in the Captions regarding the Pumps around 08:08. Recently graduated Marine Engineer btw.

I work in the maritime industry and specifically work with automation electronics. You couldn't be more right. Most of the systems I have to work on are, quite frankly, garbage.

@@wysoft I work in heavy industry where everything is either PLC or DCS controlled. Older electronics from 80s and 90s can be fairly robust, but protection protocols programmed into these systems tend to be so complex that they cause more problems than they solve. Simpler equipment is almost always more reliable.

Sonntag Abend kommt ein Video von einer Escher-Wyss-Dampfmaschine auf einem Schweizer Raddampfer, mit strukturierteren und somit besseren Erklärungen. Außerdem ist es dort deutlich heller, was die Bildqualität mit meiner GoPro verbessert. Gerade im Kesselraum erkennt man in dem Video hier ja echt gar nichts.

Steam Engine or Steam Turbine in the 1970ies? IIRC Steam Turbines were fairly common on large Cargo Ships back then, and it's a shame no such Plant has been preserved operational. But I always thought that the Stettin was very outdated as "traditional" Steam Ship when it was decomissioned in 1981, and only the improved Manouverabilty compared to a Diesel Ship kept it in Service for so long. Well, plus the Fact that it was Government owned, and the German Government really has a Habit of keeping ridiculously old Equipment in Service. Especially the Fact that it had Stokers shovelling Coal as late as 1981 really is something that I can't imagine anywhere else. Pretty much the same Facts apply to the Bussard, a Buoy Tender which was built in 1906 and kept in Steam until 1979. It's a operational Museum Ship in Kiel today. Mind you, Coal fired Steam Ships in the 1970ies may be ridiculous from a rational Point of View, but these Ships probably wouldn't be in Steam today if the German Government was a bit more "up to Date". One of my Classmates (I'm studying Marine Engineering in Flensburg) works on a Navy Tug Boat built in 1967 which has a fairly interesting Diesel-Electric Plant. But it probably will be sold either to some 2nd/3rd World Country or for Scrap. I'm still keeping my Fingers crossed that one of the Bremen-Class Frigates will be preserved as static Museum; I'd really like to see a Combined Diesel and Gas Turbine Plant once; albeit not in Operation.

Es gibt noch den Zerstörer Mölders liegt in WHV als Museumsschiff ein Dampfturbinenschiff mit 4 Kesseln. Die Anlage ist allerdings eine Hochdruckheizdampfmaschine mit ca 88 bar (1275 psi ) Dampfdruck. Leider sind die Maschinenräume nicht zu besichtigen. Ich war selber 6 Jahre als „ Heizer“ auf diesen Schiff. Diese Anlage war sehr anspruchsreich für die Besatzung.

The Engine Room on the Stettin is open for Passengers, like on most German Museum Ships. If I ever visit America, the Paddle Steamer Natchez and one of the Liberty Ships definitely are on my Bucket List. If at least one of the three Victory Ships sails again would be great too, IIRC that would be the only operational Turbine Ship in Preservation. Britain is great for Steam Engines too, and much closer to me. I'm planning to visit many Engines there, such as the Kempton Steam Museum, Crossness Pumping Station, Newcomen Engine Replica at Black Country Living Museum, and the Smethwick Engine in Birmingham, that was built in 1779 by James Watt himself.

The Image Quality could be better though, especially in the Boiler Room. I blamed my Gopro for that first, but it turns out that the Light in the Boiler Room is so weird that a proper Camera (Sony FDR AX-53; 1000€ Camcoder) struggles there too. I considered uploading an improved Version of this Video first, but abandoned that Idea as I realised that it wouldn't be much better. There also is a minor Mistake regarding the Pumps around 08:08, but it's so small that it doesn't justify taking this Video down and uploading a fixed Version. See my pinned Comment for more Information.

It was really, really empty that Day. You can watch my latest Video of the Flensburg Steam Fair, where I included Footage from the Stettin too (much better Image Quality btw.). There isn't much Footage from the Stettin though, because the Engine Room was so crowded with Passengers, and the Steam Ship Alexandra was even worse. When I recorded this, I actually had booked for the Day before, but the Trip was cancelled on short Notice for having only three Passengers. The following Day, (when I recorded), there were eight or nine Passengers. The Stettin can carry up to 180 Passengers, but only 25 are allowed in the Engine Room simultaneously.

I'm not working on it (yet) but only visited as Passnger. I used to work on a different Steam Ship named Alexandra in Flensburg though, while I wa studying Marine Engineering there (aka until last Friday btw.), and may change to the Stettin now, because Hamburg is much closer than Flensburg to the Place where I actually live. I occasionally volunteer on the Cap San Diego in Hamburg since Years too, but without being an actual Member of the Club that runs it though.

Added in the 50ies, for 400 V Triple Phase. The original Steam Generator can still supply the 110 V Single Phase Grid though.

Steam still has its Place. Most Power Generation is done with Steam Turbines, and also Piston Engines still have their Niche Applications. The Spilling Steam Motor is still built today, for Use e.g. in Refineries or Chemical Plants. These Places have Steam abundant anyway, and Steam Motors are inherently Explosion-proof by default. For the same Reasons, they often use Fireless Steam Locomotives, the last of which were built in the 1980ies (in Germany). A large Scale Renessaince of Steam Vehicles is not going to happen though, Steam Powerplants get Efficiencies similar to Diesel Engines by using ridiculous Steam Pressures and even more ridiculous Superheating, making the Steam so hot that any hotter would literally destroy the Steel. With Temperatures that could safely be handled on Ships, there is no Way to get anywhere near the Efficiency of a Diesel Engine; you just can't bend the Thermodynamics of the Carnot Cycle. The last Steam Turbine Ships are LNG Tankers, which were more economical with Steam Turbines as the Liquefied Gas is constantly boiling inside the Cargo Tanks, and it is more economic to just burn that Boil Off Gas as Fuel than to re-liquefy it. Until 15-20 Years ago, it was not possible to burn Natural Gas in Diesel Engines, so LNG Tankers had Steam Turbine Plants as Boilers can burn pretty much any Fuel if you use the appropiate Burner. Ever since Dual Fuel Engines came up, that Niche for Steam Propulsion died too. The last Steam Turbine LNG Tankers are approaching 20 Years Age now, and it probably won't be worth it to keep them going much longer. The only two Cases for (Commercial) Steam Ships I think of are the new Attempts at Nuclear Propulsion, and Combined Gas and Steam Turbines, where the ludicrous Waste Heat of Gas Turbine Exhaust Gas is reclaimed in Boilers to power a Steam Turbine, similar to Combined Cycle Powerplants.

Audio and especially Video Quality aren't the best though. That's why I'm planning to record and upload a better Video of it this Summer, with a large Sony Camcoder and External Microphone instead of GoPro and that MediaMod-Thing. Low Light Performance of GoPro's just isn't all that good.

That's because Marine Steam Engines condense the Exhaust Steam, either to feed the Condensate back into the Boilers or only to increase Efficiency by increasing the Expansion Ratio (see my Escher-Wyss Steam Engine Video about that). Steam Locomotives use the Exhaust Steam to create a Draft in the Furnace by exhausting the Steam through a Blast Pipe, resulting in the characteristic and relatively loud Chuffing Noise. Probably the loudest Thing in the Engine Room of the Stettin is the Condensate Air Pump, which unfortunately is barely visible in this Video.

Thanks, a similar Video about a large Two Stroke Marine Diesel Engine is underway- If all goes well, it will go online May 8 at 2000 German Time (6PM UTC). I'm also in Contact with some Swiss Steam Ship Operators, because I want to make a Steam Engine Video of one of their Paddle Steamers.

There are a few Inaccuracies regarding the Pumps, see my pinned Comment for that. I'm currently working on two more Steam Videos, one showing Steam Threshing with a Locomobile, and one of the ridiculously over-engineered Uniflow Engine on the Swiss Paddle Steamer Stadt Luzern. That one is limited to 1200 HP, but actually has 1600 or even 1800, not sure right now.

@@Genius_at_Work Most people won't notice. The only thing that matters is that I can smell the hot oil. Keep doing these videos!

That's not all that wrong though; Inertia still is a Thing and the Engines of the Titanic were on a completely different Scale than any that you might see today. Such Masses still take their Time to accelerate. Because Movies are the Way they are, Things certainly are "overdone" there, but Titanic's Engines just were a lot less responisve than the Engine here.

Huge difference in scale in those engines, indeed. Titanic's low pressure cylinders were 97 inches in diameter! The crank shafts per engine were about 118 tons. The outer (wing) propellers measured over 23 feet across and weighed 38 tons on their own. Trying to reverse that much inertia in 5 seconds would likely cause things to come apart. If you search on KZfaq for some stationary steam engines, you'll see a historic monster of similar size in use at a pumping station.

Now that's odd; you're the second User commenting about a thumping/knocking Sound. Can you tell the Points in the Video where you hear it? I have seen/ heard a few Steam Engine Rooms on Museum Ships, and there seems to be nothing wrong with the Stettin. Btw. I have a Video about firing up a Steam Ship coming up some Time in Summer; I volunteer as Stoker on the Steam Ship Alexandra in Flensburg. Another one is a very similar Video to this one, but about the Two Stroke Diesel on the Freight Ship Cap San Diego, coming up in May (unless the Hamburg Harbour festival gets cancelled again)

I have watched the video again,but with not being in the engine room it is impossible to locate the sound source or direction and the possible cause but it seems to time with the engine.Roly🇬🇧.

@@rolanddunk5054 Just mark the Moments like this: 01:23

I heard a bit of a rod knock, but probably not enough to worry about. The rod bearings naturally wear. They are sacrificial, to avoid wearing the steel crank pins. In some cases, they can be tightened, in other cases, you need to recast the brass. A little looseness isn't always bad, compensates for any misalignment.

They are exactly the same as on the Titanic, except the Titanic mostly had Double Boilers (IIRC around 25 Double and around 5 Single Boilers), which just are two Boilers like this mounted back to back. There's not much to make Noise though, and the Engine itself is very quiet too. I'm used to turbocharged Diesel Engines, so to me, even naturally aspirated Engines are fairly quiet and Steam Engines are literally silent compared to any Diesel. I find the Boiler Rooms startlingly dark though. That's why I might re-shoot this Video with a better Camera that can handle Low Light Conditions, unlike the GoPro that I was using here. I'll wait with that until this Video falls out of Favour with the Algorithm though; I don't want to throw away 200-500 Views per Day.

There are two more Videos on my Channel where I go a bit more in Depth to why Steam Engines offen are compounded (aka triple Expansion, or double, quad etc). These Videos are about Swiss-made Engines; one on the Paddle Steamer Stadt Zürich, built by Escher-Wyss; and a stationary Sulzer one, driving a Flywheel Generator. I explained Compounding in my pinned Comments though, as the Explanation is way too long to put it in the Video. To say it shortly, Compounding is all about Temperature Gradients.

@@Genius_at_Work I actually just watched both of them. They are some of the best steam engine content I've ever watched.

@@Aieou472 I might have got another one coming up; I'm currently in Contact with the Lake Lucerne Ship Operator to make a Video about the Stadt Luzern Paddle Steamer. All other Swiss Steam Ships have very similar Engines, but the one on the Stadt Luzern isn't just unique in Switzerland but the whole World. Other Steam Videos that I'm planning right now are firing up a Steam Roller, and a Steam Locomobile driving a historic Threshing Machine.

Thanks for the first ever Donation on this Channel. Sorry for the late Reply btw; apparently, KZfaq doesn't tell directly that a Comment came with a Donation, hence I didn't see it until now. I don't usually reply to Comments that are just un-specific Feedback, as that makes it a bit tricky to come up with a better Response than just a generic thank you. Ignoring Donations would be rude and ungrateful though, but I didn't know that this Comment was one until 5 Minutes ago.

@@Genius_at_Work no problem, good work you doing there, btw my first donation too, and i plan to do it more, i've been enjoying youtube for the longest and it's time to show some support and appreciation. it's not much but i watch a ton of videos , imagine lol i wonder how much was the youtube cut on this?

It's a Shame that it looks like no such Ship will be preserved operational, but I can see why. The Water Tube Boilers on Turbine Ships are much more expensive to maintain than Scotch Boilers like on the Stettin. There is a very similar Hip to the Stettin, named Wal. It had the Scotch Boilers replaced by Water Tube ones in 1964, and these Boilers are a huge Problem today.

@@Genius_at_Work It's crazy that not more of these are preserved. A true work of art in every way. They almost have a pre historic feeling. Like they are alive when in operation. At least we have great footage.!

@@pstreetgarage7304 I'm really interested in Turbine Ships since I visited the HMS Belfast in London. The American Victory in Tampa and the Lane Victory somewhere in Calfornia used to be operational but a grounded since Years because of Boiler Problems, and I don't know if they will sail again. The Lane Victory in Richmond California looked like she would sail again soon in 2018, but I don't know of any Progress over the last four Years.

I applied as Mechanic for the German Polar Research Ship Polarstern a few Months ago. A Friend of mine used to work there as Navigation Watch Assistant, and he told some Stories about his Duty Officer getting stuck in Ice, so the Captain told him "don't be so gentle" and slamming the Telegraph from full ahead directly to full astern and back every Minute or so. The Polarstern is powered by four Deutz Inline-8 Four Stroke Diesels at 19,200 HP, driving two Shafts with Pitch Propellers. These Propellers allow to go from full ahead to full astern weithin Seconds, as the Shaft always rorates at the same Speed and just the Pitch of the Propeller Blades is adjusted. The Propellers were built by Escher-Wyss, but I'm not sure if they were built in Zürich/Switzerland, the Factory in Ravensburg/Germany, or if Escher-Wyss had even more Factories around the World.

Assuming a Speed of 150 RPM (I think thats's realistic for Full Speed, if not too much. Can't find exact Numbers right now), it has roughly 100,000 Nm of Torque. At 100 RPM, it would be 150,000 Nm, as Speed and Torque are proportional. Given that Steam Engines can have nearly their max Torque at a very slow Speed, it's not surprising that the Engine reverses quickly from half ahead to half astern.

Yes and intermediate positions can be used to reduce the amount of time that the intakes are open, to moderate down the power more economically than with the throttle.

There's an excellent Video by @The Great Big Move about that, explaining how there's much more to being a Stoker than just Brute Force Coal Shovelling: kzfaq.info/get/bejne/i5qho7GbvtGnimg.html Today, the Stettin barely ever runs faster than Half Ahead, which means that the Engine only runs at ≈1/4 Power, making the Job of the Stokers fairly relaxed compared to what it could be like. Compared to really large Steam Ships, it's also fairly easy as the Coal Bunkers are small and located right next to the Furnaces. Larger Ships had Coal Trimmers to move the Coal inside the Bunkers (for Stability Reasons), and Coal had to be wheelbarrowed around the Boiler Rooms which all made for a complicated Logistic Task.

First of all sorry for the late Reply, I was abit busy over the Holidays. Do you mean a Telegraph Failure? I guess you use Vocal Commands then. Modern Ships have Dynamo-powered Emergency Telephones on the Bridge, Control Room, and at the Emergency Controls for Main Engine and Steering Gear for such Scenarios. The Rudder Chains aren't overly loud; the Video gives a pretty good Impression of that. Condenser Vacuum is standard on most Marine Engines. Without it, Compounding wouldn't work all that well. I don't know of any Marine Engines which expand into atmospheric Pressure, except very old ones perhaps, and the Murray River Paddle Steamers in Australia which actually have more like Locomobile/Steam Roller Engines. Many Inland Ships actually have the Condenser for Vacuum only, as they pump the Condensate overboard and use Lake/River Water as Boiler Feed Water. At least the Stettin doesn't expand into the full Condenser Vacuum, as it has a Valve to control Backpressure. You can see that Valve being operated at 04:42. Dunno about other Steam Ships; IIRC does the Alexandra in Flensburg where I am volunteering on not have such a Valve, but as a Stoker I'm mostly busy with the Boiler so I might have missed it so far.

What Salt do you mean? If you are talking about Limescale in the Boilers, the Steam/Condensate/Feed Water System is a closed Loop, so the Exhaust Steam Condensate is pumped back into the Boilers. The Boiler Feed Water Tank is sufficiently sized to compensate Losses from the Whistle, Leakages and Machinery that doesn't exhaust into the Condenser like the Deck Winches. This means that the Feed Water doesn't have to be topped up with Sea Water, so there's no Way of Salt getting into the Boilers. The Fact that the Stettin never stayed at Sea for longer than a few Days helps with this; larger Ships that sailed for Weeks or even Months without Chance to top up the Feed Water Tanks had Desalination Plants, which evaporate and condense the Sea Water in a Vacuum. The Salt is disposed as highly concentrated Brine in such Plants. They are still standard on modern Ships for Fresh Water Production, and the Vacuum lowers the Water Boiling Point below 100°C, so they can reclaim Waste Heat from the Engine Cooling Water.

I was going to mention this also... Definitely not with the intention to detract from this video of the Stettin which is excellent by the way! It really is remarkable though, and special that the Badger continues on in regular, commercial use. I've had the pleasure of riding across Lake Michigan on her on two occasions and totally enjoyed both trips. The only thing that could have made it better is if I could have talked my way into an engine room and boiler room tour lol.

The Skinner engines on Badger are in square enclosures, you can't really see anything working. Many years ago I got aboard Medusa Challenger, which had a single Skinner, just a big square silver box.

I recently made a similar Video on the Swiss Paddle Steamer Stadt Zürich, and am currently in Contact with the Lake Lucerne Shipping Company to make a similar Video on the Stadt Luzern. The Stadt Luzern has a Three Cylinder Uniflow Engine, which is kinda unusual. A major Difference between the Stadt Zürich and this Engine is, that the Stadt Zürich has all Pumps attached to the Engine, while this one is so large that there are separate Pumps only. It's kinda the same with Diesel Engines, although a similarly powerful Engine as on the Stettin would still have attached Pumps and the Engines with separate Pumps are large Two Strokes, with at least 5x the Power.

@@Genius_at_Work thanks 4 recommendation --its another wonderful vid of a great little ship and its impeccably kept machinery!!

@@martingruffalump5484 That's just the Way Switzerland is. Btw. regarding said Pumps: The Waverley may have separate Pumps as well, given the Engine's Size and Power. Plus there is a minor Mistake about these Pumps in this Video; see my pinned Comment for that.

IIRC, it became pretty much irrelevant there when Walschaerts Valve Gear came up. Almost all German Steam Locomotives used that since the 1880ies, although most Locomotives since the mid-1920ies were from a standardised Kit System anyway.

It sails Mai-September, mostly on Weekends. Here's the WIP Schedule for 2023: www.dampf-eisbrecher-stettin.de/downloads/Fahrplan_2023Vorlufig_Stand_28.11.2022.pdf

@@Genius_at_Work Thank you Genius and have a great day

They train them themselves, just like on any other German Museum Ship (or Heritage Railway). I started training as a Stoker on the Steam Ship Alexandra in Flensburg, while I was studying Marine Engineering there (aka until last Friday btw.), but couldn't finish on Time. Maybe I will continue on the Stettin, as it is much closer to my actual Home. Certain Crew Members like the Captain, Officers and Engineers must be licensed Seamen like me though.

Pretty much. But the Eccentrics themselves are what the Cam Shaft is in an IC Engine; the Eccentric Rods are more comparable to the Push Rods between Cams and Rocker Arms.

Now watch this: kzfaq.info/get/bejne/fdOlqK-Ct8uUZpc.html

Dunno how much Steam is lost, but the Stettin has no Way of replenishing Boiler Feed Water. The Water doesn't go directly back into the Boilers though, there is a Feed Water Tank acting as Reservoir between the Condensate Oil Trap and Feed Water Pump. The Stettin only maintained a Fairway into the Port of Stettin (1932-1945) and then broke Ice on the Elbe Estuary and Kiel Canal (1945-1981), so it never spent more than a few Days "at Sea" and could just bunker Boiler Feed Water in Port. Larger Ships had Fresh Water Generators, that evaporate Sea Water in a Vacuum and then condense it to distill Fresh Water. The Vacuum lowers the Boiling Temperature to increase Efficiency. Modern Ships still use the same Technology, and the low Boiling Temperature allows to reclaim Waste Heat by heating the Sea Water with High Temperature Cooling Water.

I originally picked bright Colours like Red or Orange for Captions, because they have a good Contrast to most other Colours. I never had Colour-Blindness in mind when deciding these Things though. This sort of turned into cursive orange Captions becoming a Distinguishing Feature of my Videos. I actually show them to my legally blind Girlfriend (she's an Albino, so she has really, really bad Eyes) for checking before I upload them, but once again, Colours are about the only Thing where her Eyes work properly.

@@Genius_at_Work I understand, and it is not always difficult to see them, in most cases it is much less distracting than white or some other bright color would be. My problem is when the colors of something in the video gets too close to the color of the text, like when it is darker inside a white or grey room and the white balance shifts to a warm color, everything becomes more red/orange. Like I said, it is more a me problem than a criticism of the video. I don't know if anyone else has the same issue, but thought it may be something to consider. Perhaps a slight shadow effect arount the text or translucent text box might help in some scenes where the colors are close to the text color? Ironically, I actually have really good eyesight, it is just that colors are not as vivid for me as they are for others.

Nowhere. It's preserved as Museum since 40 Years, one of the many Museum Ships in Hamburg.
