A Maersk vessel loaded with Russian fish and South Korean electronics will next week become the first container ship to navigate an Arctic sea route that Russia hopes will become a new shipping highway.

The Arctic voyage by the 3,600 20-foot container capacity Venta Maersk is the latest step in the expansion of the so-called Northern Sea Route, which is becoming more accessible to ships as climate change reduces the amount of sea ice.

The brand new Venta Maersk, one of the world's largest ice-class vessels, will also collect scientific data, said Maersk, underlining that the voyage is a one-off trial for now.
