The Crazy Amount of Power Needed to Move World Largest Container Ships

[@rickashcroft8226]

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.

Excellent answer. Thank you. You get a lot of bad info on the computer. Poorly researched etc. Gotta be careful. So much so that l reaIly wonder about AI. l've been using it for awhile now. Some good info but many egregious mistakes, misinfo. So much so it makes me wonder about alI the terror surrounding its use. Tho, l've no doubt if/when it's finally squared away it could do real damage.

[@ThyPredator]

Not to mention the 2-Stokes in these large ships are dual fuel which is usually not mentioned and the engines get about 10% of their power from the DFO. The compression of the cylinder does not create enough heat for NG to ignite. DFO is injected on the upstroke as well to create the ignition source, which then ignites the NG. NG requires 500degCelcius+ to ignite where DFO only around 200degC. 4-Stokes can come in dual fuel or full NG based which have added an electric spark source (like a spark plug) so they are technically no longer a compression engine as the fuel is ignited with a spark like a petroleum based car.

[@nombreapellido9038]

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

[@JerryWalker001]

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.

[@edhale6528]

Car carrier I was on burnt about 20 gallons of fuel oil per mile. Carried 4000 cars so equaled about 200 mpg/car. Plus a home for 20 people that made all our power and water and heat.

[@TheChiefEng]

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.

[@alexandermenck6609]

What is surprising if the engines develop 50 - 60MW? Even if the efficiency is about 160g/kWh, it’s almost 10to of fuel - per hour. However, that’s less than 1l/h per container which makes it 2 - 3l/100km per container. On a truck it’s rather 10 - 15l/100km.

[@pbdrmmr6883]

Clearly, the creators of this episode did NOT consult with someone as knowledgeable as you are about ship engines used in container ships. Frankly, they should correct the narration after consulting with you about the errors you mention and, presumably, the errors you spotted, but did not mention. Thank you for your detailed comments.

[@duncangatland6021]

Power required is proportional to the speed cubed ...P=V³. So going from 85% of Power to 100% will add about 5.5% more speed. Design of all Marine Engines is very conservative. Experience and technology allows layer models to have power output increased over time. A known example is 51% in power output from essentially the same design- size etc over temperature years.
