Panama Canal draught restrictions spark liner surcharges
- version_five 3y agoWikipedia says this about the northwest passage: Therefore, the Canadian commercial marine transport industry does not anticipate the route as a viable alternative to the Panama Canal within the next 10 to 20 years (as of 2004). Curious if there is an update. Seems a no brainier for Canadian sovereignty to invest in this, so I expect we won't.
- sp332 3y agoThere are some extremely sensitive habitats up north. A spill could be a disaster for some endangered species.
- version_five 3y agoThat's really a throw away answer. Is there something concrete you want to share? As written it just sounds like a lazy excuse for not engaging with something, which could have been done by not commenting. I don't understand what the point of even writing it was.
- MrLeap 3y agoYou seem frustrated with the environmentalist perspective. I think it's a common sensibility to just want to engage with engineering problem and theory craft solutions, don't let ant pesky things like conservation slow the discourse down, it's ballast! The fact is we're all playing at our ideals here. This is a message board, we dont decide policy. Consider having some more empathy for people who prioritize different things than you do.
- version_five 3y agoI don't see how it's a perspective. It's the equivalent of "that's probably like, bad for the environment or something", which is the exact opposite of "curious conversation". If people want to have an adult conversation about the environmental negatives of a northwest passage shipping, cool. A shallow dismissal like the post I replied to isn't that, it destroys intelligent conversation. People are entitled to their opinions of course, I can see people didn't like my comment.
- MrLeap 3y agoIf you go on the attack immediately, that shuts the door on most intelligent conversations. If you re-read what Sp332 said, and your response, do you think there's much incentive for Sp332 to "share something concrete"? Do you believe that, in a vacuum, your comment looks like it came from someone who would engage with an alternative opinion in good faith? The fact that you're talking to me now makes me think you might engage in good faith! Ya built a wall to climb with your opener though. Every word of it reads like you're telling them to shut up.
- photonerd 3y agoThe irony.

- sp332 3y agoIt's annoyingly content-free, but since I didn't have time to look up details at the time, I thought I could at least bring up some of the stakes involved. I didn't try to convince anyone that shipping up there was a bad idea. It's just a nudge so interested people have a direction to look in.
- labster 3y agoDon’t ship oil through it then, ship food and consumer goods. Demand for oil is going to drop a lot in 20 years anyway.
- loeg 3y agoCargo ships carry their own fuel, which can still leak.
- hinkley 3y agoThey run on some really nasty shit too.
- jonasdegendt 3y agoThere's multiple orders of magnitude in difference between the amount of fuel a ship carries, and the amount of oil a tanker can hold. Think measured in hundreds of thousands versus tens of millions of gallons. If we start accounting for every single externality for every solution for a problem we come up with, we might as well stop leaving the house at all.
- Xylakant 3y agoThe Fremantle Highway was burning and at risk of sinking in the Wadden Sea, off the Dutch coast of just a week ago. This would have severely damaged the entire habitat - and that was a car carrier only. Spills from minor incidents are a concern as well, especially in habitats that are important, slow to recover and already under a lot of pressure. https://www.bbc.com/news/world-europe-66393507 https://www.bbc.com/news/world-europe-66393507
- loeg 3y agoA fuel oil spill from a cargo ship is not a trivial externality to be ignored! Yes, it's a smaller order of magnitude than an oil tanker. But it's not de minimis.
- nradov 3y agoLong term the industry seems to be moving toward ammonia fuel. https://spectra.mhi.com/how-ammonia-will-fuel-the-ships-of-asia https://spectra.mhi.com/how-ammonia-will-fuel-the-ships-of-a...
- justrealist 3y agoThis might be true in an absolute sense, but I'm really skeptical that it's true in a meaningful relative sense, because nobody has ever listed (to my knowledge) environmental habitats or biomes which are not sensitive. Like, if someone said "the Aleutians are extremely sensitive, but the Marianas are an OK place to have an oil spill all things equal" I'd grant the former more weight. And if the the counter is "all environments are sensitive" well OK, great, but that doesn't really help us make decisions in the real world.
- StanislavPetrov 3y agoIt certainly can be meaningful (whether or not it is in this case). Obviously oil spills are devastating to any habitat, but some habitats are home to a wider variety of (and more critically) endangered wildlife and fauna than others. An oil spill in the Gowanus Canal, while terrible, would be far less meaningful than an oil spill in a much more pristine environment because the place is already mostly toxic (although not nearly as bad as it was in the past).
- justrealist 3y agoI think that's a cop-out. Of course environments which we've already denuded of all ecology are more expendable. Can you name a pristine (or at least, not-sterilized) natural environment which it's relatively OK to destroy relative to the polar arctic?
- kwertzzz 3y agoOn land, I guess we would agree that an oil spill in a pristine rain-forest is worse than a pristine desert. If you need a quantitative measure, one can use e.g. the number of difference species per area (biodiversity) to know the area where an accident has the least impact. Or maybe the number of endangered species. Granted, computing these metrics are however quite difficult. However, what is easy to measure from space is the amount of chlorophyll in the surface water of the ocean. Besides coastal areas, the Arctic stands out as relatively chlorophyll rich. https://commons.wikimedia.org/wiki/File:AYool_SEAWIFS_annual.png https://commons.wikimedia.org/wiki/File:AYool_SEAWIFS_annual...
- grecy 3y agoA friend is sailing it right now. There is still a good deal of ice. It's almost a certainty to open every year now, but only for 1-8 weeks, then it's blocked by ice again. 20 years ago there was no guarantee it would open at all during the summer.
- augusto-moura 3y agoIs this personal cruising/yatching? Do they keep a vlog or blog? Looks like something I would be interested in watching
- grecy 3y agoPersonal yachting. There is no internet :) ... he would rather not have Starlink, the whole point is to get away (and he lives in the Yukon anyway, being away from connection is the whole point)
- augusto-moura 3y agoI don't mean live updates (while that must exist at some level, at least for sharing with family), but a lot of blogs and channels that I follow from people living aboard do have some updates posting, either scheduled, weekly for example, when they have easy access to ports or internet in the sea (there are some expensive, high latency satellites), or no schedules, just updates when they feel like it [1]. No pressure anyway, is just something that I'm enthusiastic about :) If they ever put out some records on how it went after it finished, it would definitely be something that I would read [1]: https://100r.co/site/about_us.html https://100r.co/site/about_us.html
- grecy 3y ago> when they have easy access to ports or internet in the sea They're a LOT further out that you think. There are no "ports with internet". > there are some expensive, high latency satellites When I drove around Africa, any kind of useful satellite internet was going to cost more than the entire 3 year expedition right around the whole continent cost! (Starlink changes that, but as I said, they're not interested) >If they ever put out some records on how it went after it finished, it would definitely be something that I would read Dozens of private yatchs sail it every year, there's plenty of info out there
- icegreentea2 3y agoWhat type of investment did you have to mind? Investments to boost commercial viability? Or improvements to boost Canadian sovereignty claims?
- slashdev 3y agoA fleet of ice breaker escorts? I don’t see how that could be cost effective.
- version_five 3y agoTFA says Panama canal slots routinely exceed $350k so who knows. If there are times of year it's navigable, there could be lots of potential support services offered - keeping it clear of icebergs (if that's a concern), monitoring, ensuring a channel with the right depth, managing traffic etc., whatever is normally done in shipping channels.
- slashdev 3y agoI suppose if you used powerful ice breakers, ideally nuclear like the Russians, and escorted ships through in a line, it could work. You couldn’t justify taking them through one by one. This kind of thing requires Canada to have long-term vision and will, things they’ve been lacking politically in the last decade or two, in my opinion.
- augusto-moura 3y agoWell, you could technically connect some bodies of water and make the trip shorter, but ice would still be a problem. The biggest issue while building the Panama canal was the accidented terrain, a lot of mountais in the way, something that is not a big of a problem so far north.
- dylan604 3y ago> but ice would still be a problem If they play this right, ice won't be a problem in the near future. > The biggest issue while building the Panama canal Don't forget about that pesky mosquito

- Gravityloss 3y agoAnd a ship transited in 2013. https://en.wikipedia.org/wiki/MS_Nordic_Orion https://en.wikipedia.org/wiki/MS_Nordic_Orion I think both passages might have shallow parts.
- daveslash 3y agoGlad I read the article. At first I (naively) thought "why? just pump more seawater?" But according to the article "it takes around 50 million gallons of fresh water to move a ship through a lock. The panamax locks lose more fresh water than the neo-panamax locks, which have a recovery system that can reclaim 60% of the water" -- A spot check on the maps shows Gatun Lake (freshwater) in the center of the isthmus. Wikipedia says it is fresh, but human made. Is anyone aware of the reason for creating the interior of the canal as a freshwater passage, as opposed to just mixing ocean water willy-nilly? Such mixing of water would probably not pass current environmental concerns (with good reason), but curious what the reasoning was from a 1913 perspective?
- kgermino 3y agoSalinity issues aside, in my understanding locks generally don’t pump water at all: they work entirely on gravity. In effect this means that a burst of water flows downstream every time the lock is cycled.
- pseingatl 3y agoCorrect.
- iancmceachern 3y agoExactly, they basically harness the natural water cycle (rain to watersheds to waterways to ocean). The one exception is with these new locks, I bet they pump a bunch of the water back now instead of releasing it, that's how I expect they get the 60%.
- Animats 3y agoNope, it's not pumped. It's a clever system where there are several storage basins at different levels.[1] In the 1960s and 1970s, there was a nuclear reactor mounted on a ship to provide power for the Panama Canal. This reduced water loss via the hydroelectric plant at Gatun Dam, leaving more water for the locks.[2] [1] https://en.wikipedia.org/wiki/Panama_Canal_expansion_project#Water_saving_basins https://en.wikipedia.org/wiki/Panama_Canal_expansion_project... [2] https://en.wikipedia.org/wiki/MH-1A https://en.wikipedia.org/wiki/MH-1A
- stickfigure 3y agoFor anyone interested in how the new (bigger) locks use less water than the old locks (reclaiming 60% of the water - without pumps!), this old Practical Engineering video explains with diagrams: https://www.youtube.com/watch?v=SBvclVcesEE https://www.youtube.com/watch?v=SBvclVcesEE They store the water in a series of basins at different levels, and use those basins to fill the portion of the lock below. It's more obvious with diagrams.

- _ph_ 3y agoPeople often seem to think that climate change eventually will lead to a catastrophic event, but before that they can live as always and are not concerned. And with some luck, that event would be in some indetermined future. But that is not how climate change is going to impact us. It is more like death by a thousand cuts. It already is started. We are experiencing a multitude of climate caused changes, most of them detrimental. Especially for those, who argue against moving to more green technologies, because that could endanger "their prosperity". It is exactly the other way around. We are globally losing prosperity because of the changes that are already happening. Like with this example. Humanity would certainly survive, if the Panama canal had to close for good. But it would be a large economic impact. And that is only one item on a very long list.
- ivan_gammel 3y agoAs long as there’s a thousand of highly motivated surgeons, thousand cuts will not cause death. The balance between doing something and business as usual is already gradually shifting: demand for climate adaptation solutions is growing and investment is going in that direction, meaning more surgeons. We will not stop climate change and will see +2-+3° eventually. Mass extinction is going to happen, sea level will rise, huge areas of land will become uninhabitable, but we will adapt and survive. Scars will be ugly though.
- adrianN 3y ago„We“ will most likely not include all eight billion of us in that scenario.
- WinstonSmith84 3y agoJust to be clear - climate change has an impact, but what's not said in this article nor here is that El Niño is the real culprit for this unusual drought in that region (and flooding in others). El Niño is totally natural, albeit it's likely to be stronger than usual due to climate change. They expect these restrictions to remain in place until next September as it's also until then that El Niño shall be active.
- joncrocks 3y agoDrought - A drought is a period of drier-than-normal conditions. Draught - A current of cool air in a room or other confined space
- Symbiote 3y agoDraught means the depth of water needed to float a vessel (from the waterline to the bottom of the hull). Americans spell the word "draft".
- tialaramex 3y agoDraught is correctly used in this article to mean the depth of water required to make a ship float. In American English this word would be spelled as it sounds, "draft" but not everybody is an American. That's why the article uses both Draught and Drought, because these are Draught regulations (heaviest ships can't use the system) caused by a Drought (unusual dry period). Since you chose an unrelated meaning of Draught I can't tell if you actually knew this and are joking.
