The journey of the PanStar Acro is only halfway over, and the harder challenge is the return leg and whether the Arctic option is commercially viable.
The 2,758-TEU container ship arrived in Rotterdam on Sunday, 22 days after departing Busan on Aug. 22. It reached its first European port, Felixstowe in Britain, on Saturday after passing through Arctic waters without assistance from a Russian icebreaker.
Rotterdam, Europe's largest port, serves as a major gateway for cargo moving into the continent, with extensive rail, road, inland waterway and feeder connections to European markets.
The journey is South Korea's first trial of the Northern Sea Route using a container ship. The vessel left Busan carrying 737 TEUs of export cargo, including chemical products, used cars and auto parts, along with 100 TEUs of empty containers.
The route between Busan and Rotterdam via the Arctic is about 13,000 kilometers, around 35 percent shorter than the roughly 20,000-kilometer voyage through the Suez Canal.
Yet the first voyage also underscored why distance alone cannot determine whether the Arctic can become a regular commercial shipping lane.
According to Busan Ilbo, the PanStar Acro encountered dense drifting ice shortly after entering Arctic waters on Aug. 31.
The vessel later encountered winds of up to 40 knots in the Laptev Sea. Crew members reduced speed and repeatedly adjusted the ship's heading as ice was pushed toward the hull. The vessel also carried out evasive maneuvers to avoid harder chunks of ice near the Vilkitsky Strait.
Despite those difficulties, no major accident or safety problem occurred during the outbound voyage.
"There were no particular problems. Those were difficulties we had already expected, and the crew made the journey safely," one expert familiar with the trial told AJP.
The expert said the return voyage should benefit from information gathered on the way to Europe, although Arctic conditions remain inherently unpredictable.
"The sea is different because drifting ice is constantly moving and the weather is always changing," the expert said. "But since they have already traveled the route once, the return trip should be somewhat easier. They now have data on what conditions were like in each area."
Busan Ilbo reported that access to outside decks was restricted because of freezing conditions and safety risks, while crew members faced prolonged periods confined inside the vessel as it crossed the Arctic.
The PanStar Acro is scheduled to call at Gdansk, Poland, on Sept. 16 before heading back to South Korea via the Arctic route. It is expected to return to Busan on Oct. 12, completing its round-trip trial.
The return journey could provide an even more important test.
Seasonal freezing will have advanced by the time the vessel reenters Arctic waters, meaning the crew could face different ice and weather conditions from those experienced on the outbound voyage.
"The conditions will be different on the way back," the same expert said. "On land, taking the same road back would not make much difference, but conditions at sea are constantly changing."
Beyond the ice lies an equally difficult commercial question.
South Korea is targeting the opening of a regular Arctic shipping route around 2030 and plans to conduct additional trial voyages to accumulate operational data and experience.
"We are aiming to open a regular route in 2030," another expert familiar with South Korea's Arctic shipping plans told AJP. "We plan to continue conducting trial voyages every year, accumulating data and experience so that we can prepare step by step for the opening of a regular route."
The expert said the government's immediate goal is not to establish a permanent Arctic service with one particular shipping company, but to determine whether the route itself is operationally and commercially viable.
"There are shipping companies that still question whether the Arctic route can actually operate and whether it really makes economic sense," the expert said. "The idea is to show that it can actually be sailed in a little over 20 days."
"The goal at this stage is not to have one shipping company operate the route regularly. The purpose of the trial voyages is to accumulate data and verify the route's economic feasibility and operational viability," the expert added.
While the Arctic route can significantly cut sailing distance compared with the Suez Canal, its competitiveness will ultimately depend on fuel savings, insurance premiums, cargo volumes, schedule reliability and the limited seasonal navigation window.
"If the sailing time is shorter, fuel costs are lower and there are no major safety problems, then from a purely market perspective it has clear advantages," the expert said.
"But there are international variables," the expert added, citing uncertainty surrounding Russia and Western sanctions as factors that continue to make shipping companies cautious.
Sanctions on Russia are particularly important because much of the Northern Sea Route runs along Russia's Arctic coastline.
The PanStar Acro crossed the route without using a Russian icebreaker, limiting the need for financial transactions involving Russian services.
"If there is a financial transaction with the Russian side, there is a risk of becoming caught up in secondary sanctions," the first expert said.
"To avoid that risk, you have to avoid financial transactions with Russia, and that means not using an icebreaker unless it is necessary," the expert said. "If the ice is too thick for a ship to pass on its own, an icebreaker has to break the ice and open the route. Naturally, that costs money."
The vessel was able to make the outbound voyage without one largely because it sailed when Arctic sea ice was near its seasonal minimum.
"Right now, this is the period when the ice has melted the most," the expert said. "The ship finds a route through the open water and sails without using an icebreaker."
The successful outbound trip therefore does not by itself establish that the route can operate reliably over a longer shipping season.
Commercial viability will also depend on whether ships can secure sufficient cargo in both directions, maintain predictable schedules despite rapidly changing ice conditions and absorb higher insurance and specialized operating costs.
The PanStar Acro has demonstrated that a conventional South Korean container ship can cross the Northern Sea Route in summer without icebreaker assistance and reach northern Europe in just over three weeks.
The remaining journey will help answer the harder question facing Seoul as it looks toward 2030 — not whether the Arctic route can be sailed, but whether it can become a reliable and commercially sustainable alternative to the traditional route through the Suez Canal.
The bigger question is whether it can prove itself a shipping route worth using.
AJP Takeaways
- PanStar Acro reached Rotterdam in 22 days via the Northern Sea Route, completing South Korea’s first Arctic container trial to Europe.
- The return voyage will test tougher seasonal ice and weather conditions as the ship heads back to Busan.
- Seoul aims for a regular Arctic route around 2030, but commercial viability, sanctions, insurance and cargo demand remain key hurdles.
