- Main Engine starting up at 02:28 Minutes
Engine Start on an Inland Tanker Ship, that transports Oil Products on the Rhine River and its Tributaries. The Main Engine is a Wärtsilä 6L20 DF Inline-6 Dual Fuel Engine, with 1170 kW (1590 HP) at 1200 RPM. It is fueled by Diesel Oil as well as Liquefied Natural Gas (LNG). The Engine drives the Propeller via a Reduction and Reversing Gearbox; the Propeller spins at 300 RPM and is reversed via a Reverse Gear.

The Cargo Pumps are started independently, because they must be started slowly and only be brought to full Speed over ~1 Hour. The Pumps are powered by Asynchronous Motors, hence their Speed is proportional to the AC Frequency. Instead of lowering the Frequency with a Frequency Converter, the Generator simply runs slower. Once the Pumps are at full Speed (= 50 Hz AC), the other Consumers can be switched over to the 525 kW Generator too.
When I win the lottery, I'm going to have one of those giant engines installed in the living room just so I can start it up whenever I want to.

Why not ? 👍
I once worked as a ship physician on a cargo vessel for 3 months. It was a very interesting experience. There is a constant humming sound from all of the machinery.
Hey I had that John Deere 60kW set on dry land. It was a Kohler set we used during utility failures. Great engine. I love the sound of it.
Nice video of a clean, neat engine room... very good of you to include the wiring diagrams that show the electric arrangements of the ship and explain how it is operated...
Pretty much everything about this Ship is as simple as it gets, especially the Wiring and the Cargo Piping. The Tanker where I'm working now has three identical Diesel Generators, powered by Yanmar Engines similar to the Main Engine here (some other Ships in the Company even use Wärtsilä 6L20 Diesel Generators btw; all Ships here are very similar). Because the Main Engine is a Pitch Propeller Plant and thus runs at constant RPM, it also drives a Shaft Generator. When loading, or docked/anchored without Cargo Operations, one Diesel Generator powers everything. Discharging takes up to three Diesel Generators, to power the Hydraulic Pumps which in turns power the Cargo Pumps (Electrics on Deck must be explosion-proof, thus everything there is driven by Hydraulic Motors). During manouvering, the Bow Thruster is powered independently by the Shaft Generator for the same Grid Stability Reasons as here, and two Diesel Generators power everything else, even though one would be powerful enough but the second on eis just running for Redundancy Reasons. At Sea, everything is powered by the Shaft Generator; the Diesel Generators need expensive Diesel Oil while the Main Engine can also burn cheap Bunker Oil.
@@Genius_at_Work How is the service record of those Wärtsilä Diesel engines ? are they good & reliable, easy to service ?
@@jandoerlidoe3412 Sorry for the late Reply, must have forgotten about that. I was on that Ship for two Weeks only and didn't do anything on the Engine besides changing a Lube Oil Filter. That's pretty much all the Crew does anyway, as Inland Ships usually don't have Engine Crew (except for Cruise Ships and the large Pushtugs that sail on the lower Rhine), and almost everything is done by Contractors. This Ship is an even more extreme Case, because it was built with EU Funds under a special Program to reduce Sulfur and Soot Emissions in Inland Shipping. Because of this special Status, the Engine actually is owned by Wärtsilä and just rented to the Shipping Company. Meaning to say even minor Maintenance like adjusting Valve Clearance or measuring Crankshaft Deflection (Things that would be done by the Crew on other Ships) are done by Wärtsilä Technicians. At my current Employer, I still didn't sail on a Ship with Wärtsilä Generators yet, but Word around is that the L20 Engine is easy to service. The Yanmar Engines that I worked with aren't bad either, as long as you ignore the Fact that the Manuals are written in terrible Chinglish.
@@Genius_at_Work Thank you for answering... what you say is so typical for modern management, to outsource maintenance to contractors, instead of having it done by your own qualified personnel.....
WONDERFUL video, without stupid music, clear and concrete !!!!
I'm actually a a bit annoyed that I didn't record the two Sounds mentioned in the Video, plus that I didn't show the Auxilary Equipment at the Port Side. I even was on my Way there but then had a Brain-Fart-Moment thinking "I already was there", which explains my sudden Turn around the 04:50 Minute Mark. Anyway, if I didn't fuck that up, the Video would also have included the Hydrofor System, Hot Water Boiler, Aircon Units and the Exhaust Ventilation Fan plus Exhaust Explosion Flap.
Thank you. This is an extremely well thought out video and camera work is excellent.
I just wanted to see what a genius at work looks like.
Thank You for the informative video
Great video thank you 😊
Wow! Thanks for the great video and all the fascinating information!
Yeah I recently watched the "old Version" and thought I can do better than that today. Good Thing I always archive all raw Footage, so I could just re-edit it. I had to Change the Exhaust Sound Clip, because the File that I had used in the old Video has become corrupted. The old Video was in calm Water in the Canal de Niffer between the Rhine near Basel/Switzerland and Mulhouse/France. Because of the calm Water, there was no Rattling and Water Rushing Sounds. Although the Engine Ran only half ahead there, so in a Way, the Clip in this Video fits better with the "Full Power" Theme, and also Shows how slow Speed over Ground is Because of the strong Current.
There actually are some Things I skipped by Mistake. Around the Seizure-inducing Light Flickring (with the Epilepsy Warning), you can see me heading back to the Port Side before turning Back sharply. I wanted to go over there to show the Domnestic Heating Boiler, Aircon Units and the Exhaust Blower. Turns out I was right and had a short "Brain Autopilot Failure" when I thaught I already was there, that also ended up causing that Flickering (from me turning too sharply). The Boiler and Aircons should be pretty self-explanatory but the Blower would have been a little more interesting. It vents the Exhaust Pipe from any potential Flammable Gas Residue after an Emergency LNG Shutdown. As additional Safety Measure, the Exhaust Pipe is also fitted with an Explosion Flap to safely release the Pressure in the extremely unlikely Event of Natural Gas igniting inside the Exhaust Pipe. All of these Devices are visible in the Video though, before the Main Engine Start. Still, it would have been nice to include them, along with the Echo under Bridges and the Blow Off Valve Sound during Manouvering.I just didn't even think of recordi g the latter two in the two Werks that I was in Board this Ship.
Btw. I recently changed Jobs and am now on my first Contract as Marine Engineer, on a small Seagoing Tanker. I have to see if I can make some Engine Room Tour or Engine Start Videos here, but these probably have to wait at least until my second Contract. Not even Photos of the Engine Rooms can be shared without Clearance from the Office, for Security Reasons. I won't ask for anything like that on my first Contract though, because I want to prove myself first. My second Contract should commence some Time around September/October. Suffice to say that the Engine Room here is quite a bit more complicated than the Inland Tanker in this Video; there are three Engines like the Main Engine in the Video but as Diesel Generators. Although it's not as complicated aß the Container Ship where I was as a Cadet 4-7 Years ago; that one just has even more Power (RPG Stuttgart: ~1200 kW Main Engine + ~900 kW Diesel Generators, Tanker now: ~9000 kW Main Engine + ~3000 kW Diesel Generators and also a 1000 kW Shaft Generator that is driven by the Main Engine, Container Ship then: 27,000 kW Main Engine + 7500 kW Diesel Generators). Interestingly enough do these three Ships show the common Propulsion Layouts for Cargo Ships of different Sizes; the Inland Tanker has a Reverse Gear, the Seagoing Tanker has a Controllable Pitch Propeller and the Container Ship has a directly reversing Two Stroke Engine. Throw in Water Jets, Schottel Propellers and Voith-Schneider Propellers, and you'd have all common Mechanical Propulsion Systems. Although none of these can be found on Cargo Ships; the first is typical for High Speed Ferries and the latter two for Double Ferries and Tug Boats.
What really blew my Mind during my Basic Tanker Training (working on Tankers at Sea requires special Certificates, Inland Tankers only for the Captain. Seagoing and Inland Shipping are under completely different Regulations) is how simple the Cargo System of the Ship in the Video is. I already knew it was simple, but not how much more complicated larger Tankers are. But that is a completely different Topic and not even that much of my Qualification; Cargo always is the Navigation Officers' Business. Perhaps I'll make a Series explaining different Types of Cargo Ships (Container, Tanker, Bull Carrier, RoRo/Car Carrier, Heavy Lift, Livestock Carrier) in the Future, but I'd need qualified Help regarding all but Container and Tanker, as these are the only ones that I have worked on. I'd work in Gas Tankers and/or Car Carriers aß soon as I geht the Chance to, but would have to refuse Heavy Lift (I'm not a good Welder) and probably couldn't Work in Bull Carriers (I don't know any Bull Companied Stil hiring Germans). Even if Livestock Companies would hire Germans, I wouldn't like working there under any Circumstances.
Great vid mate.
Nice vid
Thanks !!!
Sounds like they are already running
That was very interesting thank you for sharing. I have no intention of getting on a big ship but if I had to all that would interest me is all the mechanics of the ship. Great detail on the video. ☮️
This Ship here is pretty much as simple as it gets; it doesn't even need Engine Crew. The Ships where I'm working now have three of these Engines as Diesel Generators, and even I'm still working on fairly small seagoing Vessels.
The charge air pressure is obviously 3 bar, not 0.3 (full power)
I was very confused by that too, but it's the Number I found in the Manual. It probably meant MPa (0.3 MPa equals 3 bar) and was just a Misprint. Sure sounds like much more Charge Air Pressure, but I preferred to put a Number with hard Proof backing it Up, even if that Proof is wrong.
Well never seen this channel before watched a video understood it liked it subscribed Good stuff
I also like to channel name genius at work I did that too I just changed transfer case oil on a 2017 BMW X3 for cylinder engine of course don't need all the power in the world anyhow I was told that I have to remove the transfer case bracket and all the other nonsense to get fluid out right... With that said I didn't do any of that I found the socket that would fit that had the 14 mm hex part in a regular 14 mm socket I separated both of them put it in and used an open-ended box wrench at 14 mm and open the thing right up put a very flexible tube inside siphon the fluid out put new fluid in and I didn't have to mess with anything critical and I saved myself about an hour to a fucking around and finding out
Strange to see 2 mini split heat pump outdoor units inside the engine room. Usually those would be outside in open air. I would assume they are used for heating the cabin and compartments on the ship, in turn the outdoor units blow out cold air into the engine room.
They're Aircondition Units. Heating is done by the small Boiler right next to them. I actually wanted to show and explain these Things too, but when heading there I had the absolute Brain-Fart of "I already was there, I must have covered everything already". That's the Reason for the sudden Turn around the 04:50 Mark, that also caused that Seizure-inducing Light Flashing. What's more there to explain is the Explosion Flap and Ventilator at the Exhaust Pipe, which are necessary when burning Natural Gas. Having forgotten to record all of these pisses me off to no End with this Video, along with the Fact that I didn't even think to record the Blow-Off Valve and Bridge Echo. All of that was in Summer 2021, one and a half Years before I edited this Video.
The Wärtsilä engine is made here in finland, i think.
Hello you are mentioning main engine is a DF engine but it runs in OTTO cycle? Can you please explain? What exact model of the W20 is it? Is it an DF or SG engine? Your videos are incredible!! I enjoy them thanks for the details.
It's a DF, using Pilot Fuel instead of Sparkplugs to ignite the Gas. True Gas-Otto Engines with Sparkplugs can't be used for Marine Propulsion, as any Leak in the Fuel System causes the Gas Supply to be stopped immediately. A DF Engine just switches over to Diesel Fuel in such a Scenario, with a Sparkplug Engine you'd be up Shit Creek without a Paddle. Leakages are detected by using double-walled Pipes for Fuel Plumbing, with the Space between the inner and the outer Pipe being monitored by Gas Detectors.
@@Genius_at_Work Also, in high horsepower ratings like this, an Otto cycle engine would be much too inefficient, and result in very less cargo being delivered to the customer... xD It would literally be burning up the profits as well as be a bad safety risk for those reasons you mentioned.
Do they not put synchronizing switchgear in because of cost of space?
It doesn't need much Space but just is added Cost and Complexity.
Should swap that Deere engine out for a real one; a DT466. Make about 250kw easily.
Not much Point in that. With Loads under 50 kW when loading or underway, a 250 kW would literally be idling all the Time. That's not good for the Engine, and very inefficient too.
@@Genius_at_Work ue true, it wouldnt have any load lol! Gotta keep wetstacking down and keep them rings seated!
