South Korea has completed, as a Pilot voyage, its first commercial round-trip to Europe through the Arctic's Northern Sea Route. Concluding the 2026 container shipping project, the container ship PanStar Acro returned to Busan on 11^th of October, 50 days after its departure on 22^nd August and a distance of 16,385 nautical miles covered.

The voyage of the PanStar Acro, a 2,758 TEU container ship, was initiated by South Korean authorities as a pilot shipping project, testing the viability of the Arctic shipping potential. President Lee Jae Myung has made Arctic shipping a priority. South Korean authorities hope to introduce regular Arctic shipping services by 2030, estimating journey time can be reduced by a third. The aim is also to strengthen Busan's role as a major Global maritime transshipment hub. With reduced ice in the Arctic due to Climate Change, it is estimated that shipping days will increase (for further information on the Arctic shipping lanes and sea ice visit the Arctic Shipping portlet and the Map Gallery). Commercial, environmental and political challenges remain.

The 50 day journey took the vessel through Arctic waters of the Northern Sea Route – NSR, from Busan to Felixstowe in the United Kingdom – 7,577 nautical miles, followed by stops in Rotterdam and Gdansk. It then returned back from Gdansk to South Korea again through the Arctic NSR – 7,660 nautical miles.

The westbound and eastbound Arctic passages were completed in approximately 6 days each, with average speeds of about 15 knots in both directions.

For comparison, voyage planning calculations indicate sailing distances of approximately 10,877 nautical miles between Busan and Felixstowe and 11,788 nautical miles between Gdansk and Busan via the Suez Canal.

From a trial voyage to a regular service

The viability of regular commercial service still remains and will depend on how much cargo the route can attract and how reliably ships can operate. According to Reuters PanStar officials were hoping for around 1,300 TEU of cargo, a unit based on a standard twenty-foot shipping container, but the vessel sailed with only 737 TEU of cargo, alongside empty containers. On the return it carried 1,743 TEU of empty containers. Shorter journey times alone will therefore not determine the route's commercial value.

Industry experts cited by Reuters also highlighted the importance of reliable schedules and the costs associated with slowing down to avoid ice, special insurance premiums and additional fuel use.

A route with political complications

Alongside commercial and environmental challenges, the voyage highlights the political considerations and a need for a Plan B. Global interest in Arctic shipping is rising due to uncertainty surrounding the Suez Canal route, linked to the Red Sea crisis and geopolitical risks. Therefore an evident need to explore an alternative connection between Asia and Europe.

The Arctic route through the NSR also raises diplomatic questions, as it follows Russia's northern coast. Reports state that Seoul officials consulted Moscow ahead of the pilot voyage about possible assistance if the ship encountered difficulties, such as becoming trapped in ice. According to Reuters, such cooperation could create friction with Western allies seeking to keep Russia isolated during its war in Ukraine, adding a political challenge to South Korea’s plans to introduce regular Arctic shipping services by 2030.
