Yara International's autonomous electric containership Yara Birkeland has successfully completed its first voyage.

The Norwegian ammonia producer and LPG carrier operator said the vessel is a first in terms of combining zero-emissions technology and autonomy.

The 120-teu, 3,200-dwt ship has been built at Norwegian shipyard Vard Brattvag, after pandemic-related delays.

On its maiden voyage on 18 November, a crew steered the Yara Birkeland from the town of Horten to Oslo — 70km (43 miles) — to be greeted by Norwegian Prime Minister Jonas Gahr Store.
