The Port of Auckland in New Zealand has ordered a full-size, 70-tonne bollard pull, electric tug from Dutch company Damen Shipyards.
The first such unit, called Damen RSD-E Tug 2513, will be delivered to Ports of Auckland in 2021.
To meet the performance of the port's strongest diesel tug Hauraki, also built by Damen, the RSD-E Tug 2513 will need a few MWh of batteries, reports InsideEVs.
It will be able to do 3-4 operations (usually in 3-4 hours) and then recharge over of a period of two hours.
“It was important to us that a new electric tug should be able to carry out normal port operations, just like our existing diesel tugs,” said Tony Gibson, CEO of Ports of Auckland.
“Our new e-tug will be able to do three to four shipping moves on a full charge, or around three to four hours work (one shipping move takes an hour on average),” he added. “A fast charge will take about two hours. This is just what we need.”
