Others were deploying some in last year or so from what i could see. That is not fast following, that is bleeding edge. What are hoping to prove from having one?
Electricity and electric motors are not something you need to learn about. It is a combination used for motive power for almost 100 years.
Hydrogen I can get to learn a bit, but even then you dont need to learn by doing.

Hydrogen I can get to learn a bit, but even then you dont need to learn by doing. At 70t Bollard Pull it is the largest electric tug in service to date by far. From the builder Damen “The RSD-E Tug 2513 completes the cycle of sustainability, being not only clean on emissions, but also in its source of power. This is great news for the region and also for other ports around the world with green ambitions. Ports of Auckland have taken a bold step in pioneering the use of fully electric harbor tugs and it is an honor to work with them on this project. This aligns neatly with our mission of reforming the maritime industry. We are not only building a tug, we are using disruptive technology to help serve the energy transition.”Note the Ports of Auckland have taken a bold step in pioneering the use of fully electric harbor tugsWords like "bold step" and "pioneering' do not suggest something tried and tested in my dictionary. Hopefully more successful than their automation project. |

History repeating itself, the worlds first 21st century coal powered tug boat.....fucking genuis Not as genius as funding a melges 40 programme with the profits of EV sales ! Que? |

Its not actually an EV.... it came down here under its own steam... diesel which explains the exhaust stacks....

The detailed design of Lithium-ion batteries is being explored all the time to find the best combinations for specific use cases of loads / cycles / duration / degradation / safety vs performance etc etc etc If in doubt look at the booming Battery R&D sector focused exclusively on Li-ion design & manufacturing - literally hundreds of billions going into this globally. Lots of learning going on! |

from Deep Purple on that other forum
You know what's funny....Ports of Auckland recently commissioned a fully electric tug boat.
They have found on delivery that they do not have the electrical infrastructure to fast charge it so they have 2 yes 2 diesel generators parked on the wharf charging it

They have found on delivery that they do not have the electrical infrastructure to fast charge it so they have 2 yes 2 diesel generators parked on the wharf charging itThat’s pretty shit of the best tug builder in the world not passing on what charging infrastructure is needed , maybe . Thats pretty shit of POAL not heeding the advice of the best tug builder in the world and having the charging infrastructure sorted before the tug arrived . It’s basically a microcosm of what’s happening with vehicles , the carmakers are pumping them out , Bombardier RP are going hard out investing in electric R&D for all their products outboards , motorbikes and jet skis . But there’s not a lot of infrastructure or clean energy out there yet I think the idea is great but it’s a shame the execution has been woeful . please note I think the IDEA is great , this post is not an endorsement of the POAL , or James Shaw or any other chip on the shoulder about all things electric ⚡️ |

I think the problem would lie somewhere between POAL and Vector - I have a lot of dealings with Vector on our project and frankly the people there should be shipped off to the old folks home, trying to get anything out of them is a challenge. My issue with this tug is it is all about virtue signalling, similar to so much corporate BS these days. I expect the tug's MO will be cruise out to the ships on battery and as soon as some serious push or pull is required the 2 big Cats will be purring away. Apparently the batteries can sustain max bollard pull for 30 minutes. Not long if they are berthing a ship in a strong wind |

The electrical connection will be quite big and it will be a shitty load to have i.e. randomly charges at approx 1300kW for two hours. The electric ferries are the same problem, as are the electric buses. At least the buses and hopefully the tug can time their charging to lower network use times.

A mate of mine lives in Penang.
. quote.."there's no EVs in Malaysia" and highly unlikely to be while there millions of cars benefit from subsidized petrol.
Price per litre - $2.05 ringit...
That's $0 75c NZD.
Soooo .. why is NZ trying to save the planet by increasing travel costs when Malaysia have 33million cars spewing pollution...
Ardern just want to make a name for herself at your expense
Remove all fuel taxes.. I say!

What about the waste water situation over there ? We could just run our shit down the roadside drains here too , save a bit of time with council consents etc . |

Makaysia may have open drains but thier sea water is Less polluted to han NZs.
Their air pollution per person is less than ours( smaller vehicles)
Cheap to live, less violence, more accepting of other cultures.
No racial divide.
No gangs or violent shootings.
NZ has a lot to learn.

but the big question is the sustaining capital consideration for battery(2240 of them) replacement. They are LTO (Lithium Titanate) they will probably outlast the tug and will be being recycled into something else after tug is gone. The Toshiba SCiB lto batteries in the tug are good for 20000 cycles before they will degrade and will still be delivering 80% capacity after 40000 cycles. So even at two full charges per day, that's over 25 years for 20000 cycles. I don't know how long a tugs diesel engine is expected to last. But I wouldn't of thought it was 25 years without some major open heart surgery. |

electric tug that has diesil generators which in turn can plug in to shore power and charge from our huntly coal burning station? Meanwhile gleeson n cox busy this weekend carting imported coal to huntly.Hmm maybe poal need to invest in solar/wind charging.
