The Guardian article glosses over a few things that are actually interesting about this ship:
- It's made out of aluminum instead of steel. The resulting weight savings make it a bit more efficient. That's something this shipping yard specializes in.
- Because it is going to run in shallow water on the river Plate, it doesn't actually have propellers but a water jet propulsion system.
The project of getting this ship from Tasmania to South America is also going to be interesting as well. It can't do it under its own power; it's designed for a ~50km crossing, not a trans Pacific/Atlantic journey. At the time, they were thinking tug boats.
apparently, 40MWh of capacity is enough to travel 40 nautical miles. The distance between Tasmania and South America is around 6,500–7,500 nautical miles.
It should take around 50 hours to fully charge its batteries under ideal conditions. That is 5 - 10 days realistically. I guess it's impractical considering that it will ferry across the River Plate.
I’m not a sparky but would you need inverters if the panels are just for charging batteries? On the other hand, there is probably already inverters onboard to provide AC power to passenger power points.
Does anyone have a feel for how heavy the weight of an equivalent oil(?) driven ship would be? It has the big number for the weight of batteries, but I've got nothing to compare against.
Spent a few months down in Hobart sussing out an antarctic science degree- really cool marine industry nexus down there with world leading research, all of the antarctic operations, and this stuff. Definitely the most nautical feeling city in Australia

Fully charged did a video on the construction of this ship early last year: https://fullycharged.show/episodes/electric-ferry-the-larges...

The other is: when will they charge? Does this ship not run at night?
Same ship, originally specced to carry tens of thousands of liters of oil. No overall displacement number, oddly.
