Try doing this at anchor off somewhere like Dubai or Singapore or Hong Kong with the outside temperature 40 degrees, and when the engine is still hot, with hot oil dripping down on you inside the crankcase. Looks fairly easy, but the reality is that it is pretty back breaking work. Brilliant video and would have made our jobs easier if we had this to view when I was at sea.

Ah yes I remember it well. Doxfords mostly, Harlands, B&W, 1966 to 1972. This is looks like it was filmed at the Engine Builders and not on a ship. Where's all the oil covered surfaces in the Crankcase. My overalls only looked like that when I took them out of the bag brand new. Think the Doxford was a 750mm Dia bore.

It becomes even more impressive when you realise that Diesel engines, especially large medium and low speed marine engines like this one, will run on pretty much anything. They can even run off of unrefined _crude oil._ So if you have a ship or a power plant that runs one or more of these engines, you can just use crude oil to power them, although they mostly use Heavy Fuel Oil (HFO, a.k.a "bunker fuel" or "bunker oil") or things like Low Sulphur Fuel Oil (LSFO), Marine Gas Oil, or Marine Diesel Oil. And to all you idiot greenies with your hair on fire: 1. These engines can run off of LNG, LPG, methane, ethane, propane, butane, methanol, and ethanol as well. 2. You don't even need to modify everything to run on just natural gas. Diesel engines are inherently dual-fuel capable. 3. And most importantly, Selective Catalytic Reduction and exhaust gas scrubbers exist for a reason. And they exist because the exhaust gases contain lots of NOx, and sulphur too if you're running high-sulphur fuel like sour crude oil. But the SCR system helps cut down on NOx emissions, decreasing the formation of smog, and the scrubber helps to remove sulphur, phosphorus, heavy metals (mercury and lead primarily), and other harmful substances. The scrubber's ability to remove almost all of the sulphur from the exhaust gases means that the amount of acid rain formed is so little you don't even have to worry about it. As a result, the container ship that you see out there, despite being powered by a two-stroke Diesel engine that burns extremely dirty fuel, can still have very low emissions. There, you happy now?

@nikitapottier36115 жыл бұрын
There are two kinds of oils in these engines. One for the combustion chamber, which comes from the alpha lubricators and pumped through holes at the top of the cylinder liner, and one for the more classical mechanical interfaces, which never comes in contact with the soot of the combustion chamber and can therefore in certain cases never be replaced (yeah... a 28years old engine without a single oil change... seen it).

That's a little baby engine that looks new at the training facility. Should show grown up engine, hot and dirty with damaged or missing special tools over the years. Or companies who save money by not supplying OEM parts that don't quite line up. Or have 12 hours of maneuvering to have to start job @ fwe to be told have to make next tide to maneuver back out. He also doesn't have hot oil dripping on him or working in slippery as shit crankcase. When engineer s die and go to heaven, this video is what it looks like. Look at the clean boiler suit, damn I'm jealous. Most ships I've been on have spare piston and crown built and ready to go so it's more swap out and rebuild later. Engineer best friend is is spray any metal to metal surface or gasket with GN metal assembly spray otherwise lost time cleaning surface s or seized together.

Just found this video, your question is 2 years old however if you couldn't sleep and still wondering well the OEM recommended interval between piston overhaul is 8,000 hours. That corresponds to 320,000 miles on a car averaging 40MPH. Unfortunately my experience with those MAN designed slow speed engines is we had to overhaul more often due to various breakage before reaching the normal running hours. When that happens in the middle of the ocean in a hot region trust me the engine is not that clean nor as cold as in the video and you better be fit if you will be the one disconnecting the cross from the con rod and dismantling the stuffing box. You get literally showered with lub oil at 70-80 Deg C. The metal from the engine burns your feet through the sole of your working boots. Plus add the ship rolling side to side, 3.5 tons piston swinging under the crane, stay clear! It can be hell in Eng. Room. I also saw the piston cooling carrier coming out of the crankcase. Fun days that was... Usual time would be around 10 hours to complete the job when everything went well and with a trained Engine team. Every 1 hour or so the Captain would call you on the phone and ask if the repair is soon to be finished. At least a good Captain would bring cold drinks during the work and then would give a case of beer to the guys once we got back under way.
