Accurate estimates of containership power demand are becoming increasingly critical due to stringent regulations, such as FuelEU Maritime, in combination with technical complexities. Ship power demand varies significantly depending on size, onboard equipment installed, and operational profile. These uncertainties places considerable pressure on terminal owners, port authorities, and developers to design and implement shore power infrastructure. This blog aims to provide guidance on this issue.

The N997 has two propulsion motors with a capacity of 900 [kW] each and a total battery capacity of 50 [MWh] - best estimate currently available. The 120 meter long ship has a fully electric drive, can carry up to 700 TEU and is able to swap battery packs en route. The vessel is designed for Chinese inland and coastal waters, covering over 600 nautical miles of routes on the Yangtze River.

Dubbed ‘the Tesla of the seas’ this fully-electrified, fully-autonomous cargo ship is already making waves. The Yara Birkeland has a 7MWh battery, charged by Norwegian hydro power. She can carry a little over 100 containers. The ship cost about 25 million dollars, about three times a “conventional ship price”, but will nonetheless cut OPEX for Yara by 90%.

Pioneering an innovative wind-powered propulsion technology, Wallenius Marine is launching Oceanbird as a next-generation, sustainable transport vessel. Here’s Carl-Johan Söder Naval Architect & Project Manager for Oceanbird with perspective on how Oceanbird promises to smash the International Maritime Organisation’s climate emission targets.

The world’s first zero-emissions, autonomous ship. This is a game changer and a result of collaboration with Kongsberg, a global technology company, that will eventually change the world of maritime transport.
