I did the math and think this is correct: 3 MILLION ft/lbs of torque! It is fascinating to me that these engines run so slowly. I'd think they'd last forever. Put a low-speed diesel in a truck, running electric motors at each wheel for drive/braking...you'd be able to tow a mountain but get decent mileage...far better than today.
Big old deep sea engines..two-stroke, direct coupled three story monsters. Just don't let the pilot ask for too many "asterns" and "aheads" or you'll run out of starting air, like we did one day in Karachi.
: to have everything cold and quiet and nothing turning...would be inposibile...even if the ship would stay one year in the same place...main instalations in the engine room would still be runing..like the boiler. That because of the green BnW MAN main engine you saw. That type of engine must be constantly heated, otherwise things inside would get broken.... life in the engine room is not so romantic like that on the main deck.
@mal54mac The generators are kept running , as well as the small boiler to heat fuel oil, air compressors, etc. They could get under way in about 15 minutes in an emergency. But if the plant was totally cold it would take up to 12 hours or so.
Of the many ships and tugs I've sailed on, only one company required the engineers to wear hardhats. Many took them off most of the time because they simply got in the way. It's just not always practical.
Frankly, I think you're more likely to burn or cut/scrape yourself on something that have your head hit... Of course, there are times (hoisting, lifts etc) when you probably should don one, but normal every day rounds - don't see it too often.

Nice review! Gerd Maersk (this ship) was my first ship in Maersk Line. I remembered the watch round as if it was yesterday, but it is 9 years since I made that watch round. I noticed the Alpha Lubricators have been retrofitted since then,
Actually, I think we only burned HFO on the main. The generators also primarily ran on HFO. Diesel was only used during the shut-down of a generator because it made for easier starting later.
And RammuDK is right about the importance of cleanliness.
Mærsk ships are renowned for their cleanliness. It's good for crew safety, and it instills a good sense of craftmanship in the crew. As an added benefit it also serves as a really good first impression during port state inspections.
This engine looks like a MAN B&W heavy oil engine. Can you please specify the type of engine and if its indeed a 7 cylinder MAN B&W HFO engine please!?
Most of the electrical power goes to powering the refrigerated containers onboard, of which we had sockets for up to 500.
Box ships of this size typically dont have their own cargo gear - the shoreside cranes do it all.
During maneuvering, the bow and stern thrusters also draw a lot of power and (depending on the reefer load) 3 or 4 generators needed to be on the line.
The main engine on this ship is for propulsion only. It has no capability to power the ship's electrical system.
Not sure what you mean by electronic, but the fuel injection timing and valve timing are purely mechanical. Of course, there are many electronic monitoring systems to monitor performance, but the engine itself runs on precise mechanics.
No, its not. The electronics that you saw control the lubricators for the cylinders. You can actually see an engineer noting the VIT and fuel rack positions. In an electronic engine, it would not be necessary to do that. Also, you can see the start air distributor very clearly during one of the shots. Electronic engines do not require one of those. I hope this has helped clarify for you :)
I work with Formula Atlantic and Formula Nippon racing cars-2.5 Cosworth 4's and 3.4 liter NA V8's respectively. I've also seen turbos removed from Audis and Subarus (suprisingly small). This is so far beyond my comprehension I can't believe it!! This is the pinnacle of human engineering on the largest scale! What are the overall dimensions of this engine?
If you think how much fuel is used by an engine that is the size of a 3 storey building, you want it to run on the cheapest fuel possible, which is basically industrial sludge from refineries ('heavy' or 'residual' fuel). It is very thick so it has to be heated up to over 100 degC so it is then possible to work in the fuel injectors. These are slow speed 2-stroke diesel engines
Heavy Fuel, aka Bunker Fuel, aka HFO, is cheaper than light oil (MDO).
Also it has good heating value. But all these marine engines can run off either type of fuel just by switching a 3-way valve from your different service tanks.
I never heard that before, but it sounds bogus. Each combustion cycle on a train engine (MUCH smaller than that pictured) uses only a tiny bit of fuel, finely atomized for complete combustion. Nowhere near the amount of energy in that shot of fuel versus a couple sticks of dynamite.
The guy who told me that was a diesel mechanic on an ice breaker for the the coastguard, dosent mean its true although he was definatley a master mechanic, but the only two reasons I entertained the thought was I trust the source, that is if he even knew it to be true for sure, and because although it is only a little diesel @ a time that little diesel goes a long way as far as potential energy in an engine. Wonder where he heard that :-(

yeah it's vrey huge! especially when a Mearsk vessl engine!even they are vry big hose vessels, but when i was travelling as an engine student this summer, i've realised that big and heavy vessel are fastre than the small ones!which is not like cars, i've nerver seen a normal truck giving more than300km/h!lool!in my case, i was working ona 175 meter container vessel, our speed was 17knots, weither 245 meter container vessl was sailing at 25 knots!!
Now that is ONE BIG diesel engine!!! i work for a railroad and i thought our engines were big!! ours are like a weedeater engine compared to that boat's engine!!! thanks for filming this!! it is AWESOME!!
Thanks for the comment. The generators on that ship (we had four mains, plus one emergency) are probably about the size of a locomotive engine (maybe even bigger)..
it is.. the big hoses you see at 0.23 are the hydraulic controls for the exhaust valve.. For air inlet no valves air used, but (i dont know how to call it in english) inlet ports..
Yeah, two-stroke engines don't have intake valves. Instead they use ports on the cylinder walls fed by a blower, or in some cases air scavenged through the crankcase by the downward thrust of the piston.
No, there's no shaft alternator, just 3 bearings and the stern tube seal. She probably has 4 Hyundai MAN B&W Generators putting out around 2000kW each. Correct me if i'm wrong but i've sailed on what looks to be a sister ship.
You probably have. Maersk has built a number of ships of this class. They have 13 of them, known as the D/G-class. There are slight differences, but they are all the same basic panamax ship.
for a proppelor to move through the water a relitavley slow speed is nessecary some ships engines run alot faster medium speed engines and turrbines turbines reach 6000rpm these theref or need to have gear atachments on to the shaft
great video, I love to see the inner workings of massive machines.
