    ------------------ABOUT THIS VIDEO------------------
    In this video, we look at why ships carry less cargo in the winter.
    We cover the loadline, and different criteria in different areas around the world for the summer load line, winter load line and tropical load line.
    We also touch on the fresh water load line, and discuss additional capacity available through the timber load lines.

      So... I want you to think about the ship moving from saltwater to freshwater, and how the lines would line up. I then need you to think about how this is caused by the denser saltwater, and not by moving cargo. Then you should consider how colder water is denser. Then I need you to go back to Wikipedia, where you pulled this script from, and read this line again: “ Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy.”
      Then make another video.

      Another difference with planes is the tropical part.

      The engines produces more thrust in the cold. It's why max takeoff weight can be lower at hot airports. Famous incident with a 747 in 42C Athens. Plane refused to climb and they took several satellite dishes skimming the rooftops. They planned on crash landing into a mountain just outside the city but got into some cooler air and got the thrust to climb, plus some controversy if they possibly forgot the glykol system. One of the closest calls that did not end in loss of life.

    I think it's worth mentioning that the load line was originally called the Plimsoll line after Samuel Plimsoll who convinced parliament to pass a law requiring it in 1872 in an effort to stop overloading vessels. We still call it a Plimsoll interchangeably with load line to this day.

      That name never made it into common use in the USA, although those in the trade may recognize it.
      I just call this out as having a grandpa who used to be the freight scheduler for the DM&IR RR back in the day - they shipped megatons of iron ore and taconite pellets out of the Duluth/Superior and Two Harbors ports. We were very familiar with watching the lakers (lake boats built as extremely efficient cargo carriers) and occasional salties (ocean-going vessels with much larger bulbous bow, etc) go through the ship channel (near the Aerial Lift Bridge) - they had their load lines clearly marked and the Army Corps of Engineers has an announcer on loudspeaker calling out the info about the ship passing by you - home port, crew headcount, cargo capacity, max draft, power plant rating, and all sorts of trivia about the crew itself... depending. In all of those years, seeing the vast majority of the "1000 footers" that ply the Great Lakes come through the channel at one point while as a kid or in college... not once have I heard Plimsoll said out loud; although I know I read it in some really old book somewhere.
      For us, we'd just call them the load lines; and for the lakers it's really funny to watch them come into port empty with a whole set of stripes visible near their bow (with the boat riding really high in the water), then leave after loading showing only the top couple of lines as it made its way back through the channel into the open lake.
      It's astonishing how quickly they can fill up those lakers at the ore and grain docks - they try to limit idle time; although in the fall there is often a whole fleet of grain ships waiting for their turn a few miles off the shore... several dozen on occasion. When they get their turn, they get in the channel - get loaded and get out ASAP.

      I suppose it works out to the advantage of the ships when they do it, at least most of the shipments I'm used to seeing.
      Those are iron ore and grain from the Duluth/Superior port, and more.
      - Iron ore (taconite pellets these days) boats all year long until it freezes and right away once the icebreakers can clear a channel in the spring.
      - Various shipments of wind turbine towers, blades and other parts during the open season.
      - Cruise ships and similar on occasion.
      - But why I mention this: the "fall special".... a whole ton of grain ships - they do also run the rest of the open season, but in the fall there would be a fleet of maybe a few dozen grain ships parked a few miles off shore. It was kind of neat seeing their lights down on the water from parts of the city with that vantage point. I went to college up there, so got to see it each year. It was cool when one of them would start making a bit more smoke as they ran up their engine. If you saw that and jumped in your car, you could beat the ship to the channel right by the Aerial Lift Bridge. The crew would often wave at you, and it was always fun to hear the ship and bridge honk their horns in salute at each other.
      Many of the grain ships were indeed salties - oceangoing vessels with the big bulbous bow vs the flat barge nose on most dedicated lakers.
      I imagine if the saltie was able to load up to near their safe limit while in fresh water, including draining some bilge water while loading (sadly they always simply have to do that to trim the load while it's ongoing, and need better processing plants) they'd be pretty safe for the normally relatively uneventful Great Lakes passage to the ocean.
      Obviously we're talking fall here, and fall and winter storms on the lake can be intense - so consider that of course.
      However once this saltie reaches the ocean, it has burned down some of the "clean fuel" it's required to burn while in US/Canada territory so they may be riding a bit higher already - then as they transition into the brackish then salt water they'd noticeably come up even more. To the point where they may need to add some ballast water to the trim tanks, just to make sure they're not riding too high on the ocean crossing. :P
      Obviously other ports' experiences will vary - grain from Odessa to somewhere along one of Europe's many rivers would be in reverse - and they'd need to make sure not to load too much initially since most of the voyage will be in fresh water, where they will naturally ride lower.

      @@Allan_son The maths there only works if you assume a complete cessation of activity and active measures to cool yourself for the hot environment. Attempt strenuous activity in the former and the results will be unfortunate in short order. Then again similar applies to the lower temperature that low survival time applies with a lack of preparation and suitable gear we can and indeed do produce Antarctic weather gear that provide sufficient insulation to facilitate survival. In fact ironically the real danger when equipped with that can in fact end up being the same as that for the hot climate, that gear pretty much eliminates the ability to effectively get rid of waste heat from physical exertion. You can actually die quite easily if you were to attempt to perform fairly modest physical activity around the Summer months while wearing the winter gear. The extra insulation the winter gear has will kill you rather quickly if you are active enough to make your body depend on it's cooling reflexes to attempt to maintain a temperature compatible with survival. The reality is that actually an increase in your core temperature will not only kill you from a smaller deviation but becomes irreversible without external assistance with a very small change. You actually need to lose more heat to die from hypothermia than you need to gain to die from hyperthermia but reducing the heat gain is somewhat easier to do without needing specialist equipment, removing insulation, drinking plenty of fluids, and laying your ass down not moving will help a lot when overheating. If on the other hand you are unprepared for low temperatures you are basically buggered because there is not a lot you can do to make your situation any better after you make the mistake of blundering into it. The fundamental reason for this is obvious, you can control to some limited degree the amount of excess heat you produce which can slow the rate at which you expire from hyperthermia but wondering into the cold unprepared is more like try to free hand climb down a cliff unprepared you made the fatal mistake before you start to experience the warning signs of the consequences. The natural forces in the situation are working against you once you realise, often heat related deaths result from you actively overwhelming the bodies ability to cool itself with physical effort. This is perhaps exactly why the body has less autonomic adaptions to mitigate the effects of core temperature deviating above normal thus why life threatening hyperthermia actually begins closer to normal temperature than the hypothermia equivalent the body can borderline shut down non vital organs to limit cold damage to vital organs but it has pretty much no mechanism to stop the denaturation of proteins from occurring systemwide if your temperature rises much more than around 2C.

      For larger vessels it's most likely too impractical to make it standard. The maintenance to have the whole ship stay watertight would be too costly and there is no practical way to upright a 300m vessel when its on the ocean. On the other hand, some smaller vessels like rescue cruisers are built watertight. Some are designed to withstand a full barrelroll without any major damage, but this necessary feature for these ships is very expensive and every aspect of the design needs to be adjusted for it.... So yeah, it's basically money and purpose.

      I am not in the shipping industry, but for questions like this you can always look at how much it would cost (and tied directly to that, is how functionally useful it is). Fully watertight vessels exist, but there are reasons that submarines aren't used for shipping. They cost more to build, are more complex to operate, and all that extra cost is just unnecessary for most use cases.

      Navy ships are build like that and can still float while their decks are 'awash' (aircraft-carrier excluded!).
      If I remember correctly, it just hampers loading and un-loading of cargo as these spaces would need to be individually opened. Also water-tight compartments require more steel and this extra steel costs more fuel because of the extra weight but doesn't provide any extra income.

    Interesting, I completely forgot about weather. I figured you could load a bit more in winter, as colder water (or water closer to 4°C to be exact) is denser and therefore provides more buoyancy

    • @phantomsplit3491

      The regulations mentioned in this video all come from the International Load Lines Convention, and is mostly intended for oceanic voyages. As the Great Lakes only affect the U.S. and Canada, these two nations have come to their own agreement on regulating load lines on these bodies of water. These regulations closely align with the international regs, with some changes here-and-there.
      I only know the U.S. side of the regs. Notably, 46 CFR 45.9 states that for modern vessels the Great Lakes are to be treated as Tropics, Summer, or Winter depending on time of year.

    So really more about the stormy season rather than the true winter. The storm season and cold season tend to overlap but just calling it winter could give the impression that it is about temperature, yet the summer tropical storm season would also require more freeboard.

  • @9501599

    Who polices these load lines? What are the fines or penalties incurred?? Cheers 🍻 Good video 📹 very informative 👏

    • @phantomsplit3491
      @phantomsplit3491 Рік тому +2

      They are usually "policed" by the port state authorities wherever they go. Many, many countries nowadays follow the IMO (International Maritime Organization, a body of the United Nations) guidelines on Port State Control to inspect foreign vessels for compliance with international regulations on safety, security, and environmental protection. Each country implements it a little different. In the U.S., the Port State Control Functions are carried out by the U.S. Coast Guard. In other countries it is a civilian government department. In other countries Port State Control is carried out by contractors.
      Say a Port State Control Officer (PSCO) in the U.S. comes aboard a vessel with an improperly submerged load line. There are some things you need to check before you jump to any conclusions (one instance I've seen is a vessel refueled as soon as they came into port, so their voyage was made properly but when I came onboard it appeared improper). But if they did in fact make an overloaded voyage, they could get a ticket for a couple thousand dollars per 33 CFR 143.301.
      That little ticket is going to be relatively minor compared to the more common "control action" taken of not letting the vessel move or depart from the port until a cause has been identified and corrective action implemented to prevent recurrence. An improperly submerged load line is grounds for "detaining" a boat as per Procedures for Port State Control, Appendix 2. So the vessel would be taken out of service for a few days (profit loss) while a rather large investigation is carried out (not cheap) before the vessel is allowed to go on its way. This may disrupt the vessel's schedule and make them lose contracts. These potential operational limitations are what really, really make vessels comply.
      Lastly, any time a vessel is detained it is required to make international notifications of the event. It looks really bad on the vessel and the company, and when the vessel is trying to bid on future contracts, the shipper may look at the vessel's history; see a recent detention; and stop considering that vessel for the contract. The U.S. not only shares detentions with the responsible international bodies, but also the public. You can Google "CVC-2 detentions" and see a report on nearly every vessel detained in the U.S. for safety or environmental reasons going back years and years.

      That would be such a scary job. You either have bad weather and no submarines or good weather and the dread of a torpedo hitting at any minute. My Grandpa was on a sub chaser in the Pacific. He was in the engine room and during a typhoon they lashed themselves to their posts and ate saltine crackers for hours. Supposedly the ship would rock so bad the screws would come out of the water so they had to constantly maintain the throttle.

    Am I right that the difference in buoyancy between fresh and salt is solely because of the displacement of the additional weight of salt in the water? So the difference in cargo weight needed to make the vessel sit on one line or the other is exactly the same as the salt content dissolved in the water?
