South Korea's first Arctic container round trip set out from Busan less than a third full

The ministry's timetable had the ship back in Busan on Oct. 5 ^[9], which made the plan a 44-day round trip from its Aug. 22 departure ^[21]. It took 50 ^[1]. That is an overrun of about 14% ^[21], on a voyage the Seoul Economic Daily said went close to plan without incident ^[9]. Outbound, the ship needed 21 days from Busan to Felixstowe, 12 of them after it entered the Arctic on Aug. 31 ^[19]. The return from Gdansk took 23 ^[20]. Authorities say the route could cut typical voyage times by around a third ^[25]. Neither report compares this ship's days with a conventional routing, so that saving is still the government's estimate.

Cargo is the weaker result. On Seoul Economic Daily's figure of 837 TEU ^[22], the ship left about 30% full ^[15]. Reuters counted 737 TEU of cargo plus empty containers ^[23]. If the larger number includes those empties, paying freight filled nearer 27% of the ship ^[16]. Even PanStar's own pre-departure goal of about 1,300 TEU ^[7] would have used only 47% of the slots ^[18].

Seoul's next step is a study. The government will analyze the voyage's distance, course, time, costs and fuel consumption, then build operating experience toward a regular route by 2030 and larger container ships around 2035 ^[6]. Until then, its plan puts data collection ahead of scheduled capacity or bigger tonnage ^[6]. That pace is slow for a project President Lee Jae Myung has made a priority ^[10], and one that officials hope will help turn Busan into a global maritime hub ^[13].

There are other ways this could go. The study could show the time saving holds once fuel and other costs are counted ^[6][25]. If it does, Seoul has a case for bringing 2030 forward. Western allies could object to Seoul's coordination with Moscow, and that could cap the route whatever the study finds ^[11][14]. Or shippers may have held back from the first load because no timetable had been published, which would say little about their interest in the lane itself.

We think the trial shows that a container ship can make the Arctic round trip ^[5], in late summer and early autumn ^[3][1], at small scale. Seoul Economic Daily presents the route as an alternative to the Strait of Hormuz since the war in Iran ^[8]. So far, that alternative amounts to one sailing of a 2,758-TEU ship that left under a third full ^[15]. We would change that view if a later sailing books more than PanStar's 1,300-TEU target and arrives on its scheduled date ^[7].
