Only by establishing a diplomatic and institutional security strategy that provides a multilateral institutional payment infrastructure and guarantees the legitimacy of sanctions-exemption provisions can a sustainable era of commercial liner shipping in the Arctic be realised, writes Kim Seung Rae.
This study provides a multifaceted analysis of the 2026 pilot project involving the operation of a national container ship, an initiative led by the Ministry of Oceans and Fisheries of the Republic of Korea. The project was launched to demonstrate the viability of the Northern Sea Route (NSR) as an alternative logistics route connecting Asia and Europe amidst deepening geopolitical instability near the Suez Canal—such as the recent crisis in the Red Sea. Panstar Line’s vessel, the Panstar Acro, was deployed for this pilot operation—resumed after a ten-year hiatus—as the government designated 2026 the “first year of a great leap forward into the era of the Northern Sea Route.” The vessel is a small-to-medium-sized container ship with a capacity of 2,758 TEU and an Ice Class 2 rating, designed to withstand the sub-zero temperatures of polar regions. On August 22, 2026, it departed the Port of Busan carrying 737 TEU of actual cargo—including chemical products, used vehicles, and auto parts—and a total load of 837 to 939 TEU, including empty containers used to ensure vessel stability.
This study identifies the reasons why the vessel embarked on the voyage utilising only about 30% of its maximum cargo capacity, examining the issue from the perspectives of logistics, naval engineering, and maritime operations. From a logistics perspective, shippers showed a strong tendency toward risk aversion, expressing deep concern over the risk of cargo freezing in cryogenic conditions, potential delays in insurance processing in the event of iceberg collisions, and uncertainties caused by adverse weather. Although the government and shipping companies actively presented temperature control measures during shipper briefings, the initial target of securing 1,300 TEUs was not met.
However, from the shipping company’s standpoint, adhering to the limited operational window of August and September—when sea ice melt is at its peak—was far more critical for the technical demonstration than delaying departure to achieve a full load; consequently, they proceeded on schedule. A fully loaded vessel has a deeper draft, which increases the likelihood of icebergs colliding with the ship’s weaker hull sections and reduces manoeuvrability. Therefore, an engineering decision was made to limit the load to 30% to ensure sufficient buoyancy and stability, as well as the necessary safety margin for rapid course changes and evasive manoeuvres while following a Russian nuclear-powered icebreaker.
Regarding the route, the Panstar Acro undertook a massive 30,000-kilometer voyage over 45 days, departing from the Port of Busan, traversing the Bering Strait and Arctic ice, and returning to Busan via the ports of Felixstowe (UK), Rotterdam (Netherlands), and Gdańsk (Poland). The vessel successfully traversed a section of the Arctic Ocean between August 31 and September 9, 2026, and—after completing unloading operations in Europe—safely arrived at its final destination, the Port of Busan, on October 5, 2026. This marked a monumental achievement, enabling the independent collection of empirical data confirming the technical and operational feasibility of an Arctic commercial route through the operation of a single container ship.
Based on data from this pilot voyage, the study conducted a comprehensive assessment of the Arctic route’s high operational efficiency and the associated commercial constraints. From a geo-economic perspective, the Arctic route reduces the travel distance by approximately 36%—to 14,000 km—compared to the existing alternative route via the Suez Canal (approximately 22,000 km). This cuts the transit time—typically 35 to 40 days on the existing route—to 25–30 days, saving over 10 days per one-way trip. Consequently, this maximises vessel turnover and provides a foundation for effectively responding to the shipping industry’s increasingly stringent Carbon Intensity Indicator (CII) regulations.
However, despite this efficiency, there are structural and operational challenges that represent fatal flaws for the liner container shipping market. The first is the “time window constraint”. Although Arctic sea ice coverage has generally declined due to climate change, the period during which container ships can operate safely is limited to three or four months a year during the summer melt season (from July to early October). From a commercial standpoint, it is very difficult to integrate routes that cannot operate year-round into the regular schedules of global shipping alliances, where punctuality is paramount.
The second issue is the risk of excessive capital expenditure (CAPEX). While this pilot operation was conducted as a temporary demonstration using an aging, 15-year-old ice-class vessel, full-scale commercialisation in the future would require the construction of new, eco-friendly ice-class container ships; the construction costs for such vessels are 50-100% higher than those of conventional ships, placing a massive initial fleet investment burden on shipping companies.
The third factor involves the volatility of operating expenses (OPEX) and control risks. The fees for Russian icebreaker escorts and polar pilotage—payable to Russian authorities for transiting the Arctic Ocean—are set at very high levels, significantly offsetting the fuel savings gained from the shorter distance. In conclusion, while its limitations as a regular liner service are evident, its utility as a “backup route” for high-tech components and energy supplies connecting Northeast Asia and Northern Europe—as well as its value in niche markets—becomes highly significant during crises involving logistics disruptions, such as the Suez Canal blockage or the need to bypass the Cape of Good Hope.
From a scholarly perspective, the most significant aspect of this study is the process of administrative and financial cooperation carried out amidst the strict geopolitical constraints imposed by Western sanctions against Russia. Russia exercises strong “preventive jurisdiction”, regarding the Arctic sea route as its internal waters and Exclusive Economic Zone (EEZ); consequently, shipping companies must obtain official navigation permits months in advance from Rosatomflot—a subsidiary of the Russian State Atomic Energy Corporation (Rosatom)—which holds a monopoly on icebreaker operations and the issuance of permits for the Northern Sea Route (NSR).
Upon entering the Arctic Ocean, a tactical ice-escort procedure is initiated: a Russian nuclear-powered icebreaker acts as the lead vessel to break through ice jams and clear a channel, while the vessel flying the national flag maintains a specific distance and follows closely behind. Furthermore, technical cooperation is required to integrate real-time sea-ice density data—provided by Russian satellites and managed by Russian pilots—with the autonomous navigation system of the vessel flying the national flag. However, following the outbreak of the military operation in Ukraine, serious regulatory compliance risks arose regarding payments, as the US and EU added Rosatom Flot to the Specially Designated Nationals (SDN) list—a move that freezes assets and prohibits financial transactions. To carry out trial operations in 2026, the vessel was able to cross the Arctic Ocean independently during the summer months of August and September—when sea ice is scarce—thereby avoiding icebreaking fees (the largest expense item) and successfully sidestepping international political risks by devising a structure that involved no service fees.
However, as year-round operations expand in the future or the transition to regular shipping routes occurs by 2030, payment for the use of Russian icebreakers will become inevitable; yet, the indirect payment mechanism implemented at that time would entail significant legal constraints. Adopting a workaround—such as settling payments via intermediary accounts in third countries or private logistics agencies for regular commercial routes—would be deemed a wilful violation. Regardless of nationality, this could make an organisation a direct target of US “secondary sanctions”—sanctions against third parties that lead to exclusion from the global financial network (SWIFT) and result in heavy fines or criminal penalties for violating Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations. Furthermore, due to the sanctions limitation clauses of global P&I clubs based in London and other European financial markets, insurance contracts for vessels circumventing sanctions automatically become void. Consequently, in the event of maritime accidents in the Arctic—such as collisions with icebergs—insurance coverage fails to apply, creating extreme logistical instability and counterparty risk, and forcing shipping companies to personally bear the costs of total cargo loss, amounting to hundreds of billions of won.
According to geopolitical and maritime network theories, South Korea (specifically the Port of Busan) is situated at the eastern terminus of the Northeast Passage, possessing the exclusive advantage of serving as a “gateway” that vessels traversing the Arctic Ocean must pass through to enter the Asia-Pacific region. While the route deviation—a key factor determining transshipment costs in maritime shipping—is virtually zero for the Port of Busan, ports in Singapore or southern China face massive additional costs because they must deviate from the Arctic route and travel southward.
This geographical advantage is fully leveraged in the “hub-and-spoke shuttle system” model proposed by academics. This is because Korea’s southeastern coast acts as a physical buffer zone that optimises the efficiency of polar navigation. Icebreakers—which are expensive to build, fuel-intensive, and inefficient in open waters—can operate solely within ice-covered stretches (from the Arctic Ocean to the Bering Sea), while the ice-free Port of Busan handles the transshipment of cargo onto ultra-large container vessels with capacities of 20,000 TEU or more. As the world’s second-largest transshipment hub—accounting for 56.6% of total cargo volume—the Port of Busan already boasts an extensive network of feeder terminals and a high Liner Shipping Connectivity Index (LSCI), enabling same-day delivery across Northeast Asia for cargo transiting the Arctic Ocean.
The unparalleled technological prowess of the Korean shipbuilding industry—closely linked to this sector—serves as a key asset for the commercialisation of Arctic shipping. Korean shipbuilders have secured a near-monopoly on Arc-7 class ice-breaking LNG carriers, commanding nearly 100% of the market and deploying these vessels in initiatives such as Russia’s Yamal project. Furthermore, to achieve technological localisation, the nation’s three major shipbuilders, the Korean Register of Shipping, and Inha University jointly developed “iFAST”—a digital twin-based software platform for analysing ice loads on polar vessels—creating a technical tool capable of predicting hull damage probability with over 95% accuracy. This technological capability is further evidenced by the construction of a next-generation, 16,560-ton research icebreaker—capable of breaking through 1.5-meter-thick ice and continuously navigating toward the high-latitude North Pole with a 50% improvement in ice-breaking performance over the Araon—as well as by the possession of ice model basin research infrastructure, a facility owned by only seven countries worldwide. Additionally, the eco-friendly three-section LNG cargo tank design—pioneered globally by HD Hyundai Heavy Industries and others—has reduced the daily Boil-Off Rate (BOR) to the lowest level in the world and improved environmental performance by cutting carbon emissions by more than 5–10% through the use of a rotor sail system that harnesses atmospheric wind. In particular, a demonstration project is currently underway to localise the “3 MW rotating electric pod propulsion system”—a key component that will significantly enhance manoeuvrability and icebreaking capabilities in polar regions. Large-scale commercialisation is expected to begin in 2027 with the delivery of commercial vessels equipped with all-electric propulsion systems, while the full-scale installation of the system on large commercial icebreaking vessels is scheduled for 2030. Furthermore, if Korea takes the lead in developing “safety standards for autonomous navigation in polar regions” based on its advanced autonomous navigation technologies—for instance, by linking the AI-based MASS (Maritime Autonomous Surface Ships) Code currently under development by the International Maritime Organisation (IMO) with the existing Polar Code—it could secure a dominant position in the global polar shipping market.
Overall, the planned 2026 Arctic round-trip voyage of the Panstar Acro is regarded as a national project of significant practical and scientific value; it transcends a mere demonstration of reduced travel distances, signifying that a domestic shipping company has acquired independent polar navigation data and practical operational experience. Although substantial hurdles remain—such as commercial limitations due to the inability to operate year-round and financial risks associated with sanctions against Russia—this initiative should be viewed not merely through the lens of immediate, full-scale commercialisation, but as a pivotal step toward the 2030 era of regular operations for eco-friendly icebreaking container ships. To ensure the success of the planned extended trial voyage and establish commercial liner services by 2030, the South Korean government and the Ministry of Oceans and Fisheries must promptly enact legislation for a comprehensive, multi-faceted incentive package designed to attract risk-averse shippers. Specifically, policies must be implemented to reduce fixed and operating costs—such as establishing an integrated logistics matching system to address the shortage of return cargo (from Europe), subsidising the cost differential between outbound and inbound legs, and introducing a “delay compensation system” (to incentivise risk coverage for polar shipping) that shares operating losses resulting from weather-related delivery delays. Additionally, measures should include construction subsidies of up to 11 billion won for new ice-strengthened and ice-breaking vessels, a 1-percentage-point reduction in interest rates for investment financing, and an increase in the loan-to-value (LTV) ratio to a maximum of 90%. Furthermore, a smart incentive system for the use of dedicated berths should be developed, featuring up to 100% waivers on port facility and mooring fees at major hub ports, as well as guaranteed priority berthing to compensate for schedule disruptions.
Ultimately, amidst the geopolitical crisis—where the Western allies’ commitment to enforcing sanctions against Russia clashes sharply with Russia’s exclusive control over the Northern Sea Route (NSR)—it is crucial to navigate a delicate diplomatic path. As we move toward future commercialisation, we must boldly move away from temporary, informal payment arrangements and actively leverage multilateral consultative bodies—such as the “ICE Pact”, a next-generation icebreaker cooperation initiative championed by a Western coalition comprising the US, Canada, and Finland—to counter the Russian monopoly. Only by establishing a diplomatic and institutional security strategy that provides a multilateral institutional payment infrastructure and guarantees the legitimacy of sanctions-exemption provisions can a sustainable era of commercial liner shipping in the Arctic be realised.
