Just for comparison: The Diesel you and I can buy at a regular gas-station has around 10-15 ppm of Sulphur. "Low Sulphur" LSMGO on the other hand has 1000 ppm and the shipping industry was really padding itself on the back, when they (where forced to) finally put a stop to using fuels with 5000 ppm in the year 2012 ... in the 1st world. Heavy fuel oil (HFO), a very popular fuel for the really big ships and essentially the garbage of the petroleum industry, could until 2020 have as much as 35000 (no, not a typo) ppm Sulphur.

They had steam vents underneath the tracks in the unloading area to heat the tank cars from below, so that the oil would be hot enough to pump out of them even in below-freezing weather.

About ten years ago, I was working as a consulting engineer to a major cities school district. I came in about 3/4 of the way through the transition from Number 5 (heavy) and Number 6 fuel oil to Number 2. The biggest issue had to do with the District reusing existing fuel tanks, piping, and transfer pumps. While the tanks were allegedly cleaned by the contractors, we still had trouble with left over heavy oil plugging filters strainers and burner nozzles when it congealed. And unfortunately the one modification the District did to the transfer pump/heater skid was to disconnect the steam and electric heaters. So you couldn’t turn the heaters on to heat the fuel and liquify the clump of old heavy oil. I remember one school where the building engineer had to manually tear down the duplex filters twice a shift, and scoop heavy oil out of the body

Chief, Excellent video. I am what I like to call a "textbook engineer". Before retirement, I was a naval architect and marine engineer. After college, I work for the marine departments of large oil companies. Using low and ultra-low sulfur fuel can present other issues. Some of these issues can be addressed by the ship, and others need to be addressed ashore. The process of fuel changes starts with the original crude oil used in making the fuel. We experienced the plugging of fuel injectors as a result of differences in crude oils used in making different fuels. If crude A is used for the heavy fuel oil and crude B is used for the ultra-low sulfur oil, and crude A and crude B are incompatible, plugging of the injectors is inevitable. These issues, 20 years ago, required testing at shoreside laboratories. If bunkers were to be loaded our ships moved fuel onboard to isolated tanks. A new fuel that was loaded into a separate tank and was not used until laboratory tests were received by the Chief. When possible we used fuel from our own company and loaded it at our docks. When we used other sources we required samples from the source. We also took samples before and after it was loaded onto bunker barges. Our chiefs took multiple samples when loading fuel. One sample was kept onboard and one was sent to the laboratory. Fuel quality is important not only for sulfur content, viscosity, and flash point, in two-stroke engines it can affect which cylinder oil is to be used. Bob

Great video, I love these episodes detailing how engineering tasks are handled aboard a ship. Very well explained.

Hi Chief. In my day when I first went to sea, we changed over to diesel to stop heavy from coagulating in the lines. In later years - late 70s, we didn't change over at all, just stayed on heavy with the usual precautions in port and a bleed through on standby. When we did changeover (say for drydock) we just operated the changeover switch and let the viscotherm do the job - closing in the steam valve by itself as the viscosity dropped. The PRV on the engine rail returned the fuel/fuel mix to the buffer tank and back to the rail. I understand the reasons for Annexe VI - it shows that the marine industry is doing its job to help the environment, as 90% of ocean pollution is from land and not from ships. Nice to know you guys are working to the same integrity as we did in my day, now 36 years ago!

Chief, very useful video for the engineers! Very important to observe the temperature and viscosity during changing over from one grade of the fuel to other. When I was worked on a chemical tanker, we had the problems with fuel equipment, such as filters and fuel pipelines system. Because was bad bunkering(quality of fuel very poor). It's depends from the place of getting the fuel and of the company! Best wishes, all kind.

Well explained. But 40 years ago we also had to change from HFO to marine diesel (as fuels were named at that time) some time before finish with engine. Simply because there was no re-circulation and stating a big MAN 2-stroke ME with cold HFO in the pipes was impossible. But I think as circulation is standard now for years, you can go from pier to pier with HFO (or what it is called now) outside critical areas ... Keep safe! br ;-)

I just stumbled on this channel, as an engineer in the US Coast Guard I am immediately hooked. It's always interesting to see how the Industry side works.

More a subset. The fuel for ships in international water is residual fuel oil. It's nasty stuff: Burning it pumps out clouds of toxic waste. Choking, corrosive clouds that erode all they linger on and cover everything with soot, and ruin the lungs of anyone exposed. It's so horrible that most countries have banned using it - which means it is also dirt cheap. Good for ships far from shore because there is no-one around to be bothered by the pollution, but once the ship enters territorial waters where that fuel is restricted it has to switch to a less polluting but more expensive fuel. It's just a way to shift the most serious pollution to a place where few people will see it.

I think for cargo ships there is something going on as well, but for cruise ships you can see it as they make it quite obvious. I heard of some ships burning "marine diesel" close to shore and in port, which to be honest i am not sure if it is the same as the gas oil or if it is even cleaner stuff. Sometimes scrubbers are mandatory to enter port as well. Other ships can switch over to LPG or run completely on LPG. And to have no engines running while staying in port, some ports have set up huge power connectors to provide the ship with electricity. I think that is not necessarily restricted to cruise ships, i have seen this for cargo ships as well. Only problem, for smaller ports the electrical power needed would be more than the power consumption of the whole city.

I believe the dieselbug lives also in the fuel tanks of ships? I've been scrubbing that gray stuff off of heating oil tanks and can imagine the damaging possibilities if it clogs fuel filters, pumps or injectors.

No offense Chief, but whenever it is that you retire, please do take up to be a professor or atleast write some books; you've got all it takes to be a good teacher🙏🏽 👍🏽

Working in a shipyard and onboard many ships for sea trials hearing changing over anouncement but never know how actually they change over the fuel. By this video i at least have an idea on it. Many thanks

Great video! Some Chief Engineer friends (cruise lines) told me that going from VLSFO to LSMGO also may cause fuel spraying on hot surfaces and risk of fire. This is because VLSFO is more viscous and seals small fractures, while LSMGO basically cleans the pipes. Is that true also for your engines?

In my experience the heavy oil circulates around the fuel system loop very hot 100c + to maintain viscoty. The MGO is unheated so the expansion and contraction due to temperature change can cause joints and gaskets to leak. After switching over an engineer is required to stay in the engine room to check for leaks.

@@cyberdiver7076 Fuel leaks from "O" rings, gaskets, seals, tube fittings, etc that have gone bad from multiple temp change and MGO solvent properties under pressure spraying (atomizing) hot fuel till maybe finding ignition source. One would be surprised the amount of fuel that can spray out under pressure, Ive seen plenty of big messes since it usually happens at night when unmanned (that's when everything bad happens every time). Usually caught by the bridge watch on CCTV when everything starts turning black or the air hazy- that's really bad. There are hydrocarbon alarms but they are notoriously fickle.

Great insight, thanks Chief. Can you talk about the fuel oil filters used for both VLSFO and LSMGO? I assume when using VLSFO, you have to operate the filters at low flux rate due to high viscosity?

I´m not a sailor, nor an engineer, but I really love your videos. You narration is epic. Thank you for sharing and making these videos. Best regards from Denmark

Another brilliant video. Thanks Chief very enjoyable like all the rest. Your Captain and crew would all be proud of you with utmost respect.

Really interesting video Chief, thank you. When you change fuels is there any potential for damage to the engine? My experience is only with car engines and the loss a few years ago of leaded petrol caused problems, and now we are getting E10 petrol which has 10% renewable ethanol which is OK for most but some older cars can suffer. Stay safe, regards from a landlubber.

Great explanation on fuel change out. When they first swapped to low silly fuel there were issues with o-rings on the fuel injectors. They weren't compatible. That was a few years ago. What do you do with the fuel samples? Pour them back in the tank or oil water separator.

Best power and efficiency is normally found with the heavy fuel as it contains more energy. With modern electronic controls the difference is lessened. Soot and other contaminants building up within the engine and exhaust stream are reduced with the lighter fuels.

Question: Is there any noticeable performance change as you transition from one fuel to another? Do both fuel types have comparable energy density per volume burned? Sorry if you already mentioned that but I didn't catch it on my first viewing. Absolutely fascinating video. With each new video you produce, I'm more in awe of the number of things a ship's crew has to keep track of.

I'm not sure a about shipping, but in the US back in the day of off highway diesel (red) to the ULS(Ultra Low Sulfur) on highway, there was a noticeable difference in performance, the red was more powerful (more power density) but put out more smoke and emissions, the new standards on diesel fuel on or off highway is the same, the only thing the red dye indicates now is that it has no highway tax applied and is illegal to run on-highway for tax evasion reasons.

@@billyboots3730 The calorific value of heavy oil is the principal reason for it's use, giving both higher output from the engines and more total power per ton of fuel. One thing that was not mentioned in the video was that engines have to start from cold on the lower viscosity fuel until the combustion chambers and injectors reach full operating temperature. The maximum output of all engines is limited by the exhaust gas temperature, running on high viscosity fuel allows about a 15% increase of power within the temperature parameters.

Thank you for explaining how VLSFO works. Pretty amazing that a black sticky oil comes out clear through the injectors

This is unquestionably quality content. I learned something useful, spoken clearly and concise. Good sailing to you!

Question: Even though an “authorized” border official also samples your fuel type when entering the zone, do they take or monitor your actual emissions? Without scrubbers … dirty exhaust is still dirty exhaust not matter what your running as fuel.

@kuebbisch

2 жыл бұрын

I guess not, because the concern is sulfur which burns to sulfur dioxide, which then gets washed out the air as sulpherous acid, a bleach like substance that killed many forests in the 80's when heavy oil or coal with high sulfur content was burnt without scrubbers for power generation (acid rain). And this reaction is just driven by the sulfur content, so less sulfur burnt, less sulfur dioxide in the exhaust.

Government regulations are a tricky balance between doing what the public thinks they want and doing what the public needs. In this case, the public thinks it wants strict emissions regulations, but in reality they need economically viable transportation of goods. And if you know anyone who works on large engines, they'll tell just how it is not economically viable to run exhaust scrubbers for the majority of operators.

@@ObamaoZedong Emission standards are a changing target in the last decades. Operators will have to calculate if a retrofit scrubber is viable, or if they just pay the higher price for fuel now. The next vessel will be equipped with scubbers for sure. I live in Hamburg, Germany (large port city). The pollution from the harbor is in the news all the time, currently they try to convince the cruise liners to use shore power instead of running their generators. I can only imagine that that will continue for cargo ships as well. I had a similar decision to make in 2000 for my car: My then 21 year old car had an unregulated catalytic converter without lambda sensor. And the vehicle started to be taxed like a car without catalytic converter. I had the choice to retrofit the lambda sensor, new catalytic converter and some motor management electronics. I did not feel that that was very cost effective, so I just kept the car for one more year while looking for a new (used) car which fulfilled the new regulations and saved some money on vehicle tax from then on. I upgraded like 3 emission classes (nothing to euro 3). Now this car is 19 years old (3 more months to 20 years old) :-)

@@kuebbisch People will complain about the regulations and emissions standards, but if you've ever been in an area with poor air quality you know they're necessary. Retrofits are rarely cost effective or even practical. Here in the US 3 way catalytic converters have been required since 1981 (the type your old car lacked, the computer/sensor-less 2 way converters came in 1975). To run efficiently with the old engines most required an air injection pump to add enough oxygen to the exhaust gasses for the converter to function. A lot of people saw an air pump they deemed to be unnecessary and a drain on already weak engine power and just removed the belt powering it. This gradually killed the converter substrate and when some states introduced emissions testing requirements the vehicles would fail, badly. Owners were faced with having to install a new catalytic converter and reconnect the air pump, or get rid of the car. Through the magic of the US testing/inspection laws being state-by-state and not federal they would just sell the car to a state with no testing or inspection requirements...
