Autonoom varend electrisch containerschip
The Yara Birkeland, the world’s first net-zero, battery-powered autonomous container ship, was delivered to Norwegian fertilizer company Yara Norge AS in November 2020. It’s currently in the Norwegian port of Horten, where it’s undergoing further preparations for autonomous operation and a late 2021 launch.

The new port construction inside the factory at Herøya is completed with only the delivery and commissioning of the port crane remaining. Once this is completed in the autumn, the plan is for the Yara Birkeland to start operations and to transport approximately 40-60% of Yara’s container volume by the end of this year. Work is also ongoing to prepare the Yara Birkeland for the first phase of sailing with reduced manning. Once that has been achieved, the ship will be developed to reach the desired level of unmanned operation during the next two years. Yara Birkeland specs Yara provides the Birkeland’s specifications (and I’ve provided some explanations in italics for landlubbers): Main particulars: Length overall (LOA): 80 m Beam (width): 15 m Depth: 12 m Draft (full): 6.3 m (Draft is the distance between the waterline and the deepest point of the ship) Eco speed: 6-7 knots Max speed: 13 knots Capacity: Cargo capacity: 120 TEU (TEU is an abbreviation for 20-foot equivalent unit, an inexact unit of cargo capacity) Deadweight: 3,200 mt (The deadweight is the difference between the displacement and the mass of empty vessel [lightweight] at any given draft. It is a measure of a ship’s ability to carry various items) Propulsion: Azipull pods: 2 x 900 kW Tunnel thrusters: 2 x 700 kW (provide side force to the ship) Batteries: Capacity 7 MWh (that’s equivalent to around 100 Tesla Model 3s) Proximity sensors: Radar Lidar AIS Camera IR camera Connectivity and communication: Maritime Broadband Radio Satellite Communications GSM Kongsberg Maritime explains: Loading and discharging will be done automatically using electric cranes and equipment. The ship will not have ballast tanks, but will use the battery pack as permanent ballast. The ship will also be equipped with an automatic mooring system – berthing and unberthing will be done without human intervention, and will not require special implementations dock-side. To ensure safety, three centers with different operational profile are planned to handle all aspects of operation. Via: https://electrek.co/2021/06/08/meet-...ontainer-ship/ |
Grappig, als men weet dat een middelgrote firma in de Brusselse rand een maandverbruik heeft van 2000kwu (en er met een 1500 kilowattuur elektrisch, aardgas gestookte Caterpilar 12 cylinder motor groene stroom van laat maken).

Ik heb geen idee wat de stroom (waterkracht) en diesel kosten in Noorwegen in elk geval spaart de gekende electrische ferry Ampere dit uit per jaar:

En het is een productie firma. Maar niet van spul dat iemand gemaakt ziet worden in de Brusselse rand. Grappig hoe low tech zo high tech kan lijken. Mare, die 2000kwu is puur elektrisch. Thermisch is het een heel ander verhaal. (de 1500 kilowatt elektrisch generator levert nog eens 2000kw thermisch, en daarvan wordt nog eens 800kw laagwaardige warmte omgezet in 500kw aan koeling) |

2000mWh per maand zou ik al meer geloven. |
De generator draait continue. En die 2000 is wat van het net afgehaald word. Bovenop de generator.

Maar de link naar Micele's wonderbootje is dat technologie gemakkelijkere greenwashing toelaat. |
