impedance problem in suez canal

<< < (5/13) > >>

BrokenYugo:
Don't forget this thing is very nearly a quarter mile long and holds up to 20,124 20 foot containers. Technically feasible or not unloading it in a hurry on site probably isn't gonna happen.

Why use boat tugs at all? I know the Pamama canal abandoned railed tugs in their new locks, but I doubt it was a smart decision.

TimFox:
News reports indicated that offloading the containers by crane onto other vessels would be a last-ditch effort if all else failed.
I also don’t understand why the renovated Panama Canal abandoned the towing locomotives.

Gyro:
Latest update. They're now using 14 tugs and have pumped out 9000 tonnes of ballast water (hope it stays upright  :D). Apparently they will need to bring in a 60m (200ft) high crane if they need to lighten further.

It does sound like the stern is more or less free though.
