You have no idea how much effort and experience is put into building such machines.

I am a naval architect with more than 45 years experience in the industry, including more than a decade spent in a research lab and also in the design department of a major shipyard. Good visuals and generally enjoyable video but you need to do some fact-checking and get you information right, I have a some corrections: wind turbine propulsion - the picture shown was of a sail-assisted propulsion system. A system that does work under many environmental conditions but is NOT a wind turbine - although they are in common use on maritime drones and pleasure craft to recharge batteries for electric propulsion systems. Second: HFO, heavy fuel oil, is NOT the same as diesel fuel, which in its variants is commonly referred to as MGO (Marine Gasoil) or MDO (Marine Diesel Oil). There are a lot of international restrictions on the use of HFO and it should not be confused with diesel fuel, which has a different set of restrictions and requirements. Third: the type of fuel has nothing to do with radiated noise. For airborne noise, the main engine, regardless of fuel type, is the primary source of air- and structure-borne noise. Underwater radiated noise is virtually always caused by the propeller. Period. Fourth: the first large LNG powered commercial ships anywhere were CONTAINER SHIPS built by NASSCO shipyard in the San Diego for TOTE, an American shipping company, not ships built years later for CMA CGM. While U.S. shipping companies and shipyards do not own or build the most ships in the world, they led the way and continue to move toward greener fuels. Fifth: the any diesel engine (and many gasoline engines) can run on LNG with some modifications. The engines you discuss here are modified diesel engines - the diesel cycle uses pressure to cause combustion of the fuel - and the primary modifications are to the fuel system. From a design standpoint, converting a diesel engine to operate on LNG de-rates the output power about 10% compared to the same engine running on diesel fuel. The engine cylinder pressures when using LNG are NOT an issue.

It's crazy how we take raw materials from the ground and turn it into this and that.

They can haul massive amounts of cargo around the world and knock a bridge down in seconds flat.

Every day I'm amazed at what man can build

Can we take a moment to appreciate what it takes to machine the engine components.😮😮

You know it’s a big boat when, you have incredible drone shots of the engine room!

The engines may be huge but in terms of fuel use they are tiny. A 50,000 ton bulk carrier burns around 0.4 tons of fuel per mile which may sound like a lot but when you look at it in terms of fuel per ton per mile it is only around 8 grams per mile per ton. So if a 1 ton car had this economy it could drive around 100 miles on one litre of fuel or around 450 mpg.

the extreme scale of these ship builds is beyond amazing , to think what tiny little men can build is just insane crazy and yet we still treat each other like dirt

"Building these ships takes months." More like years.

Shout out to the dude who got to fly the tiny drone around the engine room 🤙

Ships powered by wind? What a time to be alive 🤯

Incredible how replacing an large engine part requires cutting a large hole in the hull to get access to, pretty much engine gets sealed within the hull once installed.

Every day I'm amazed at what man can build. Ships powered by wind? What a time to be alive .

Propulsion units and engines are not the same thing. Replacing external propulsion units whilst not in dry dock and running is NOT possible.

I would be more impressed to see the machine tools used in the creation of this engine.

Why is it that stuff transported on road is a shipment and stuff transported on a ship is cargo?

@03:47 is the answer you are looking for... equivalent to a 545 hatchbacks ..one Hatchback has 180HP...so 98000/180 = 545 cars..this power can move 19000 containers upto 23knots

I just can´t believe that us humans are capable to build such sophisticated machine with thousands of individual parts thats fit with 100% accuracy and gigantic scale.

I think it would be cool to see a video about that Coast Guard cutter & it's "dual hulls" ! It could be part of a video on the whole cutter, since it's an ice breaker. 😊

Think one of these would fit in my Honda civic

The largest combustion engines ever built can be found in container ships. However, the engines in the new ultra large container ships tend to be smaller in size and power but instead on one main engine, they have two main engines and two propellers. All the main engines in large container ships and tankers are two-stroke engines. In ones has to be pedantic about the clip, it is not mere the turbochargers ability to compress the combustion air for the engine that increases the efficiency of the engine. It is also the fact that the turbocharger is driven by the exhaust gas. The part in the video where pistons are mentioned, the shown is not a piston but a crosshead. Since this type engine is very tall (long piston stroke), a device is needed between the piston rod and the crankshaft to covert the rotating motion of the crankshaft to a vertical movement of the piston. This is the job of the crosshead. On top of the crosshead, the piston rod is mounted. In principle all two stroke main engine may be considered low speed engines since they typically operates at a max rpm of 85 - 160 rpm depending on the size of the engine. HFO and Diesel are not the same thing. HFO, which stands for Heavy Fuel Oil, is a residual fuel that has basically been discontinued since the introduction of the IMO 2020 regulations. Diesel is mainly a distillate type fuel and is today used it two different quality ranges in shipping where both have a very low Sulphur content compared to earlier. The general speed of container ships have dropped a bit since the introduction of the ultra large container ships. Up to the last large container ships with only one massive main engine, a top speed at around 26-28 knots was not unusual. The ultra large container ships, mostly with two main engines typically has a speed between 19 - 24 knots. At all time, the sailing of maritime ships is all about fuel efficiency and optimization. You never ever sail at 100 load on the main engine unless absolutely necessary. The extra speed you achieve between 85% engine load and 100% engine load is typically pretty small while the extra consumption in fuel is very high.

its so cool how they make these engines!

Incredible what an army of men can create. Makes me very proud

Ive worked in the Naval industry for 35 years, and never ceases to amazes me how Big some ships can be. Specialy these Enormous Cruise ships...the human ingenuity is a real God's gift.

I'm amazed how these ships float without just rolling over as they always look top heavy.

Thanks for sharing great video. Now I, and I am sure others would love to see the machines used to machine the monster parts, like the crank shaft, or pistons if you know of any videos like this please advise. Tia

“Next, pistons are installed…”(shows connecting rod) “pistons are connected to the crankshaft” (no, no they’re not. They’re connected to the connecting rods)

So lets make it an even 100.000 hp🥵

Tankers are one of the reasons I want to see them up close

How big is your engine? Person 1: V12 Person 2: 1000 HP MSC Tessa: 4 Floors

did you say building a ship that can transport 20.000 containers can take months? ive seen potholes taking longer to fix in germany.

going to visit my sisters boyfriend on a triple E class mærsk tomorrow. can't wait to see just how massive it is in person. especially being used to a 27 foot sailboat

Excellent footage and information (as always).

as a person that has a beach house right next to the port we see ginormous Titans entering the port each hour each second each millisecond, it’s insane to see these giants floating on a giant body of water! truly a masterpiece made by mankind.

What’s so remarkable about the modern day shipping is that it is so unremarkable.

Good show. When these monsters are empty it seems the props are half out of the water.

quality cooper, hot fiber glass insularors are crucial. under stress & in high temp, motors should keep working, without failuring.

Jesus i never thought that pistons would move up AND down

Incredible levels of skills,teamwork and commitment to the work.

MASSIVE Pieces Of Machinery. The Way They Stay Afloat Is Unbelieveable.

These ships are awesome in every way.

The first one even pirates cant mess with.

The crazy amount of power is what makes the ship go fast and is not what is needed for it to move!

The Baltimore situation brought me here

The sheer scale Of those engines is amazing

That drone shot through the engine bay is very cool.

As big as these ships are they’re tiny compared to the ocean

Excellent video - thank you.

wow such a large ship

Nuclear marine engines can move these twice as fast

These huge ships size always mesmerized me.

That was a connecting rod being assembled to the crankshaft 🤣🤦 Not a piston

I am watching your video in India 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳

Would like to see a video about how those new, modern wind sails work.

Proud to be working with the World's biggest carrier.

Super excellent heavy cargo ship production with heavy mechanical propeller # ❤,🇵🇰

10:22 - No, the vessel is not able to perform revenue service during a power unit replacement.

c'est assez incroyable ce que l'homme peut créer.

It is very interesting just how relevant this particular video is at this moment in time.

The best way to improve shipping efficiency is to process materials and manufacture on the same land mass as the raw materials are extracted.

Very interesting video - thank you. I had no idea there were removable panels in the sides of the hull of these things. That’s a seal you’ll want to be confident about!

Sir - how big did you say the crankshaft had to be? -- Yes.

proud to be a seafarer at msc cargo

I work in the motercycle industry and work with bike engines daily. I saw the piston and gasped so loudly my family came into the room to check on me.

Watched the entire video waiting for how much fuel is consumed 😢

The ship owners hire short crew in the engine room to make it look bigger.😅

The „shipping“ via ship is the most efficient way to „ship“ containers. But: They do not have filters nor NOx reductions. This should be installed immediately.

Amazing engineering. Simply astounding.

The California Governor is going to require all ships that dock in his state to be all electric by 2024.

You know what would be more environmentally friendly? Brining the manufacturing back to the import countries so that there is 0 time on a container ship

So much info, but proof read and check your info please! How would an engine be on the "underside" of the hull?

Hadir nyimak guys👍💪

Wind assisted power!!! Wow.... Like sailing?

Whenever I see ships this big. All that floods my mind is, “How is that floating on water”. Even though I know exactly how it floats.

I wish they showed they types of careers in schools or atleast do not teach us College/university is the best eay in life but to strive for career goals

98,000 horsepower? Got damn.

Thanks from İstanbul

Impressed with the drone flight didn't hit any metal

Great content, I found it so interesting

i think is a amazing human a do.. great job. 🤩

How can you test for reliability, as opposed to functionality and performance, during commissioning? It takes years of fault-free operation to demonstrate that. The engines are no more complex than a diesel locomotive, just much much larger.

not even a mention of how much a container ship consumes in tons of fuel

Naval Architecture and Ship Surveyor used to work to carry various inspection during construction and in service inspection

In February 1931, the first container ship in the world was launched; the Autocarrier, owned by Southern Railway UK

beautiful ships

I'm surprised where the hell do people find all the metal to build these huge ships. Even though countless ships were sunk in over a century.

Asking for a friend, will it fit in a honda civic?

I wonder if one built scoops on each side that ducted the water to the prop .

Cant wait to see trains these massive, traveling cities

i've seen so many ships holes in my day, i took an early retirement

It's very hard 💪

What struck me was how (relatively) little has changed from the days of the Titanic. Pistons, crankshaft, propellors. It’s all the same just with added bells and whistles to make it more efficient, faster and stronger.

HFO is not diesel, that would be GFO or Gas Fuel Oil. HFO is Heavy Fuel Oil. HFO resembles Bitumen and has to be heated (usually by High Pressure Steam) before it can be burned in the engine. And the Wind Assisted Propulsion is not a Turbine as mentioned.

This is monster not a ship. Hat's off those who build it and those who operat it

Imagine being able to use the wind to transport none perishables 🤦🏻‍♂️

I was luck enough to be in the merchant navy when steam was the power to drive these monsters. The QE2 was my first ship and she was a beast of power!!! I loved that lady and will die with fond memories of her

Im struck at the lack of advancement in the engine room.

Imagine a world without Seafarers..

Pollution level high :D
