But he didn't explain it. He talked around the issue with circular reasoning. The solution to the "bulk carriers are not specialized ships" is to make a regulation that requires a specialized baffled ship to carry cargo subject to liquefaction. My guess is that, him being Chief, his Ship's Owner would not be happy with him using the R-word out loud, even on his personal channel. He says it would not be economical, but if the only way to ship bauxite is in a baffled ship, the playing field is leveled. The same was said about double-hulled oil tankers back in the day.

According to a report from Allianz, this is consistent with the prior two years but down significantly from 2011-2017, which averaged 42.4 cargo vessels lost per year. This is out of 60,000 large cargo vessels worldwide, according to their report, so around 0.03% of all large cargo vessels were lost. They also report that converted VLOCs (Very Large Ore Carriers) are on their way out, with 43% of the fleet scrapped since 2017 in favor of newer, more reliable, and safer vessels. Cross-referencing the 18 vessels with Wikipedia, there were a few dozen dead and missing. This is unfortunate, but it's a reality of working in some of the most dangerous conditions on the planet, and yet the numbers have decreased over time. We don't see airline passengers fitted with parachutes or ejection seats. Instead, we see improvements in general safety such that fatal accidents are extremely rare. Even in countries where you probably shouldn't fly on the national airline, odds are extremely low that you won't make your destination. Worldwide, there were about 40 accidents of large commercial airliners in 2020, a rate of about 0.03% of the global fleet. While not all were hull losses, you can see the comparison in safety levels.

Excellent discussion. Another hazardous material is metal turnings. Instead of liquefaction, you have fire to worry about. Metal turnings are coated with oil and where the oil isn't they will rust.

in a perfect world, safety would trump profit. We do not yet live in that world so it becomes mitigating risk and that is balance. Balance is pretty reasonable most of the time and usually allows for enough leeway to keep it safe. Thanks Chief for responding to what most of the viewers seemed to see as the potential solution.

Thx Chief, great, logical & through explanation of why baffles are not practical for (certain thpes of) bulk cargo. Semi-liquid potential is not sufficient reason to justify the costs & related complications of intermittent use then on-board storage issues. Your industry has developed specifications for testing for moisture content. Captain & Chief are trained in these matters. So your video was great at explaining all these indepth problems & industry practices to insure safety when ships travel on all oceans in all types of weather & related forces acting on these ships. Another great video Chief! Carry on Sir!👍👍👍👍🧑🔧🙂☕

I am a fan of naval design and I want to thank you for your intelligent and understandable explanations of the why of these things. On the longitudinal bulkheads; good sense there Sir, the problem of the shipper is interestingly different than the engineer designing a combat ship. In that position, it was found that with empty compartments it was better not to divide the area fore and aft. When center line compartments were installed if the outer plate was penetrated it was found that the ship would flood asymmetrically leading to a capsize. The designers who make ships depend on a huge history of why ships fail. It is not always clear on the first contact why this is.

Correct. Every solution creates a new problem when something fails. Some ponder that the Titanic would have stayed afloat and level longer without watertight bulkheads. They were designed for 1 set of conditions, but not for unforeseen conditions.

As a guy who has driven (and still do) tanker trucks,and grain trucks, baffles can be handy to have,but they make unloading a complete bitch! Plus,you can't really baffle solid load tanks! You'd never get it unloaded or clean enough to not contaminate the next load. Key board marine architects are apparently a thing huh Chief? Good video clearly explained!

Thanks Chief. It seems that sometimes, the simplest solutions, can open another can of worms. Shipping has been going on for a couple thousand years. I have no doubt that at some point the designers of the ships had already considered baffling or not. The effectiveness vs the cost and weight. Your videos offer some real lessons, for the rest of us 'land lubbers.' I hope you can keep it going and maybe at some point, do a new series on something. You and your team aboard ship work hard and when they get the chance, like sailors since the beginning of time, play hard, enjoy life in the moment, and make a slight effort to stay out of trouble!

In the 1970's the US government mandated seat belt interlocks on cars. One could not drive a vehicle unless the seat belt was engaged. This caused all sorts of problems and in a few years, the SBI mandate was eliminated. As the Chief said, baffles would work but cause a host of other problems. Wet bauxite can be measured so if a ship is sunk due to the surface effect, somebody made an error. A partial solution is to have on board test equipment to measure moisture content. It takes hours or days to load a ship so there is ample time for the crew to perform the tests.
@Markle2k2 жыл бұрын
Because it takes hours or days to load, a single squall line can come along and invalidate your tests. Your solution also does not take into account human failings like greed or the pressure to skimp on safety because they had gotten away with it before.

Nice explanation. I did hear that specialized ships used with dredging had holds that had 'de-watering' equipment. Since the silt/sand/mud from the dredge is of course saturated with water, these could somehow pump the water out of the hold while more silt/sand/mud was being loaded in. I'm sure it's not practical on most bulk carriers, but I found it interesting and at least somewhat related.

I admit, watching your previous video and reading those comments, I was caught up in the "could this work" train of thought, not the "should this work" train of thought. I was convinced baffles would be a good idea. However, this video highlights that a far more simple solution would be to not accept cargo that is too close to liquefaction. Bulk solids have static friction keeping them roughly in place even in rough seas, where a liquid is... a liquid. I guess a follow-on question I would have then is this: how water-tight are the bunker doors? You sometimes travel through rough seas and heavy storms carrying this cargo, how do you mitigate any rain- or seawater entering the bays from the top? Is it a tolerance threshold or are they really well sealed? Thanks for another fascinating video, Chief!
@SpaceCadet4Jesus2 жыл бұрын
Thankfully, someone repentfully has seen the light and in this case admits and rejects the fallacious crowd mentality thinking. You are forgiven, my son. Go and sin no more. The cargo hold nor the covers have seals against water. Since the covers overhang down past the hold lip, it affords sufficient protection against expected water intrusion. Water intrusion occurs when the deck water is of sufficient height past the cover while prolongingly remaining on deck.

While I'm not familiar with the transport of dry cargoes, I have some experience in LNG shipping from an engineering/financial analysis perspective. In the case of LNG, baffles are generally not used (even though they would not impeded unloading like in dry cargoes) because ships normally transport a full load of LNG, and without voids the cargo won't move around. Small amounts of LNG (say
