If you have one charge point at the loading dock and another charge point at the unloading dock (and charge the ship during the average loading / unloading times).. theoretically you can estimate the max range between the two docks where you never have to worry about charging.
- jacquesm 5y agoWell, you'll never have to worry about charging anyway, but ships that don't move are losing money so ideally charging would not add to the turn-around time. I think it is the money that the owners would be worrying about. 7 MWh is a pretty beefy battery, I am going on the assumption that its size was carefully chosen to give it sufficient capacity during the operating life of the vessel to serve its route. Filling that up from an industrial drop at 20KV with 100A is doable in under four hours.
- lallysingh 5y agoI wonder how much money is saved in fuel and maintenance.
- jacquesm 5y agoIt may well be that the decision to go uncrewed was given in by either higher purchase price or higher operating costs so they had to do one more thing to make the ship competitive. But making an electric ship uncrewed is feasible, doing that with a diesel would be a little bit more tricky, boats that size are - unsurprisingly, I guess - mechanically quite complex. In this case they 'crew' the boat from the shore, which will probably work well as long as conditions are good, but I'd hate to be in the driving seat of one of those and to see the comms link go down.
