Large segments of international shipping would be completely untouched by ice-highways; Australia and Brazil would still be sending their Iron Ore the same ways, and Saudi Oil likewise. Out of 10Gt a year, even with ice conjoining Russia and Canada, then down to the Hudson, I don’t see even half of that on the ice, which was why I mentioned originally that ‘I would consider it complete with only ten lanes in each direction’. There are still immense volumes of refrigerated cargo and time-sensitive goods which would benefit from fast, cold transport. And, those goods earn higher premiums; I expect the ice-highway’s margins would punch above their market share.
In terms of load-transfer, I would love it if global deep water ports were some genius of efficiency—a few huge or wealthy ports are such marvels. But, in contrast, the bottleneck at most major ports was just recently a year-long global boondoggle. I’m not sure you want to argue that it was somehow the best possible solution; the real solution to transferring loads involves replacing union labor with robots. And THAT is much easier to do at a new transfer-location, which can connect to one of the more numerous small ports, for the shorter, local hop that would be needed. Giant ports are only necessary for giant ships, and those are only necessary for long voyages. By switching to ‘last-mile’ boats, you can go small, which lets you utilize those hundreds of under-utilized small ports, closer to their destination. That sounds like efficiency, not loss.
In regards to your concern for “an entire tech base...” being needed; yes, it is a different tech-set. And, I don’t see that as a limitation; the tech required is minimal capital cost, mass, operating labor, and it provides an immense multiple of capital-into-capital, as well as energy-into-energy. (A few hundred kg to lay 200,000 tons of ice each winter is not an ‘overwhelmingly exorbitant tech base’ that would prevent feasibility. Similarly, spending 1 joule to pump and spray water that transfers 3,200 joules of heat is a simple device with insane energy-yields, not an insurmountable tech-hurdle.)
The construction, the crews, the control systems, the navigation, the onboard power systems, the structure of the ship: all different.
If you want to see what a modern cargo ship looks like and how it operates, Chief Makoi on YouTube has many videos.
Long story short: what you see on commercial cargo ships is the cheapest most reliable technology available. It has been incrementally refined over more than a century.
You are basically proposing to start over, and your idea has some activation threshold issues.
Without the ice way going far enough there’s no flow
Without ships able to sail it reliably, probably with heavy automation, there’s no flow
Without massive scale it’s more expensive—there’s no upfront initial profitablity
The current regime is evolved. Mostly it was small, modest improvements that pay off immediately. This is how the industry evolved to it’s current form. It means it is suboptimal but “trapped” at a cost minimum.
Thank you for getting into details :)
