I very much doubt that any standard type of plug and socket would be used. Much more likely would be overhead electrification, a bit like that used for railways. When the ship docks, a gantry at a safe height would swing out over the ship. A moving contact at high level on the ship would make contact. 1000 amps at say 33 kv should be doable. 30 minutes to unload and load the ship would allow about 16 MWH of charging.
They said that electric cars would never be viable, yet thousands are now in use and are generally giving satisfaction.
