Wow, this is a really good paper. Supplementary info is really great too- they get into details down to floating charging port stations as part of the infrastructure. Surprising how much demand is from tugboats. I have questions about how you'd safely hook up 5 MW connections, but it's definitely solvable.

There are IEC 60309 industrial power connectors that can handle 8MW (1000V, 800A).

There are also power connectors for cruise ships while they are in dock that handle lots of power. It looks like they use IEC 80005 for shore power. It looks like it is AC only but probably could be made to use DC.

Isn't that 0.8MW?

8001000=800,000. (81 and 5 zeros).

looks like 800kW to me. Nice catch.
