Korea's Breakthrough in the Global Icebreaker Market
By 2029, the Republic of Korea will build its first new medium-class icebreaker for Sweden, based on a Swedish-Finnish design. This represents a decisive breakthrough for the country’s shipbuilding industry and opens up significant prospects in the highly competitive market for specialized vessel construction.
REPUBLIC OF KOREA SERIES
While the Ice Pact members are busy pursuing their own ambitious icebreaker construction programs, Korea’s largest shipbuilder easily won a Swedish government tender to supply a next-generation icebreaker, the technical specifications of which are not disclosed, for winter operations in the Baltic Sea.
The Swedish icebreaker fleet, comprised of six vessels, with the exception of one icebreaker, is quite old and unable to escort large-capacity merchant vessels during harsh winters, as was the case last winter.
For Sweden, whose export and import operations rely heavily on maritime trade, a temporary blockage of the Baltic Sea by ice is economically unacceptable. At the same time, the country’s poor economic and financial situation prevents the relatively rapid construction of a new icebreaker fleet to replace the old vessels.
In previous years, Finnish shipbuilders had been urging the Swedish government, like an Indian fakir conjuring a cobra dozing in his hat, to order six new icebreakers from their neighbor, which would further improve relations between the two countries.
The result was ultimately the same as in the tender for new fighter jets for the Finnish Air Force in 1992 and 2021, when the Swedish Gripen fighters lost miserably to the F-18 and F-35 fighters.
Essentially, the two countries stuck their tongues out at each other, which is perfectly understandable for anyone familiar with the nature of relations between the two neighbors.
The Swedish political class largely views Finland, with its mere century of independence, as an immature democracy, a nascent country. Finnish politicians harbor an inferiority complex toward Sweden, while in the collective memory of the Finnish people, their western neighbor remains an occupying power that ruled this colony with a heavy hand from the 14th century until 1809.
It is highly likely that Sweden will order the remaining five icebreakers from the Republic of Korea, which, with its experience in this field and its vast shipbuilding capabilities, could become a major player in the icebreaker construction market.
If someone had predicted in 1974, when Korea produced its first domestically designed passenger car, that 1998 would mark the beginning of the Korean auto industry’s global expansion, they would have been suspected of feeblemindedness.
However, in 2025, a country with a population of 52 million people living in a territory of 100,000 square kilometers (smaller than Cuba) ranked fifth in the world for automobile production, only slightly behind Germany.
There is no doubt that Korea, having recently chosen the Arctic as the main engine of its economic growth for a large-scale national renewal, can quickly replicate its automotive success in building ice-class vessels and thereby play a significant role in the development of the Arctic.
A Contract Aimed at the Future
The Swedish Maritime Administration has signed a contract with the South Korean shipyard HD Hyundai Heavy Industries to build a new icebreaker. The ship will be larger than today’s icebreakers and can break a channel up to 32 meters wide. The new icebreaker is planned to be delivered in 2029.
HD Hyundai Heavy Industries disclosed on April 22 that it had secured an order for one icebreaker worth $348.9 million (514.8 billion KRW) from Sweden. This vessel is equipped with icebreaking capabilities at the polar operation class PC4.
In particular, this order is highly significant as it was secured in competition with icebreaker powerhouses such as Finland and Norway amidst heightened global interest in the Arctic shipping route and the exploration of the Arctic Ocean, marking Korea’s first entry into the global icebreaker market.
Sweden’s Six Icebreakers
The Swedish Maritime Administration currently has six of its own icebreakers: Ale, Atle, Frej, Idun, Oden, and Ymer. The work vessels Baltica and Scandica also have icebreaking capabilities.
Ale is specially built to be able to go through the Trollhätte Canal to Lake Vänern. Built in 1973 by OY Wärtsilä AB, Helsinki. Modernized and upgraded in terms of both materials and technology.
Atle was completed in 1974 and was thus the first of the icebreakers in the Atle class, which also includes Frej, Ymer, and the Finnish icebreakers Urho and Sisu. Atle is built to assist merchant shipping in all types of ice in the Baltic Sea and the Gulf of Bothnia and has over the years proven to be very well adapted for this purpose.
Frej was delivered to the Swedish Maritime Administration in 1975 and thus became the second Swedish icebreaker in the Atle class. Like the others in the same class, Frej is excellent at mastering all ice situations that can arise in the Gulf of Bothnia and the Baltic Sea.
Idun was built in 2006 at Aker Yards in Norway. She is 74 meters long, 17 meters wide, and has a deadweight of approximately 1,300 tons. This places her in size between the Atle class (Atle, Ymer, and Frej) and the smallest icebreaker Ale. The Swedish Maritime Administration acquired her from the Norwegian shipping company GC Rieber in March 2024.
Oden was built in Gothenburg and commissioned in January 1989. The purpose was to function as both an icebreaker and a research vessel, and she has had both roles since then. In September 1991, Oden became the world’s first non-nuclear-powered surface ship to reach the North Pole, a feat that has been repeated on several occasions since then. Oden has also carried out several missions in Antarctica.
Ymer was delivered to the Swedish Maritime Administration in the autumn of 1977 and thus became the last icebreaker in the Atle class. In the summer of 1980, Ymer carried out a research expedition in Arctic waters. Ymer has had common rail, an injection system that reduces fuel consumption, retrofitted.
Unpredictable Winters and Structural Changes
The order also reflects a larger structural development in northern Europe. Transports of iron ore, forest products, and steel from northern Sweden and Finland are increasing in line with the industry’s transition to fossil-free production. New investments in mines, battery factories, and fossil-free steel in the region are also expected to drive sea transport further in the coming decades.
At the same time, winters in the Baltic Sea have become more unpredictable. Even though the long-term trend is for a warmer climate, periods of heavy ice formation can still occur, which requires robust icebreaking capacity. In recent years, several winters have been more demanding than expected, which has put pressure on Nordic icebreaker resources.
Sweden Will Gradually Replace Its Aging Icebreakers
Sweden’s current large icebreakers were built in the 1970s and 1980s and are approaching the end of their technical lifespan. At the same time, the need for icebreaking is increasing, not least as a result of more demanding winters and tougher ice conditions at sea. Without icebreaking, several ports in northern Sweden risk closing for up to 130 days a year.
“Nine out of ten goods exported and imported to Sweden are transported by sea. Swedish basic industry is dependent on sea transport operating year-round. Our icebreakers have served Sweden well for decades, but now need to be gradually replaced. This is an important step to ensure preparedness and keep ports open year-round,” says Erik Eklund, Director General of the Swedish Maritime Administration.
New Design for a More Powerful Icebreaker
The new icebreaker is based on a joint Swedish-Finnish design developed in collaboration with the Finnish Transport Agency and the design firm Railotech. The design has been verified through extensive tests in a basin and wind tunnel before the procurement was carried out.
The ship will be larger than today’s icebreakers, can break a channel up to 32 meters wide compared to today’s 24 meters, and at the same time reduces energy consumption by 40 percent.
The wider channel is particularly important as the merchant fleet is gradually growing in size. Modern bulk and container traffic requires wider fairways in the ice to be able to operate ports efficiently even in difficult winter conditions.
Dedicated icebreakers are vessels equipped with specialized functions to break up sea surface ice and open shipping lanes in ice-covered seas. Key technologies include a reinforced hull, propulsion to push away sea ice, and a specialized hull design for ice removal.
The Swedish icebreaker ordered by Hyundai Heavy Industries is a large vessel measuring 126 meters in length and with a displacement of 15,000 tons. It features PC (Polar Class) 4 icebreaking capabilities and an electric propulsion system. PC4 refers to the ability to continuously break ice with a thickness of 1 to 1.2 meters.
The tenders have been evaluated based on predetermined criteria, where price, warranty, and delivery have been the basis for the evaluation. A total of four tenders were received, and HD Hyundai Heavy Industries submitted the most advantageous tender.
The South Korean company is one of the world’s largest shipyards and a global player in shipbuilding and marine systems. The company has delivered over 2,300 vessels and has experience of advanced solutions, including the delivery of vessels with engines that can be powered by methanol.
The renewal of the icebreaker fleet is part of a long-term project where planning for additional icebreakers is underway.
The name of the new icebreaker has not yet been decided.
A Clear Trend in Global Shipbuilding
The choice of South Korean HD Hyundai Heavy Industries also illustrates a clear trend in global shipbuilding. The large Asian shipyards continue to dominate the construction of complex special vessels, even in segments that have traditionally been strong in Europe.
The shipyard in Ulsan is one of the world’s largest and has delivered over 2,300 vessels. It is particularly strong in advanced projects, from LNG vessels to large offshore units and vessels with alternative fuels such as methanol.
For European shipyards, this means another lost order in a segment where competition has become increasingly fierce. At the same time, it is not uncommon for Nordic icebreakers to be built in Asia, even though the design and much of the technical expertise still come from Finland and Sweden.
The fact that the design was developed in close cooperation between Sweden and Finland is in itself strategic. Finland has long had a strong position in ice-going ship design, and several of the world’s most advanced icebreakers and Arctic merchant ships have been developed there.
The technical focus on energy efficiency is also clear. A 40 percent reduction in energy consumption is significant in a segment where ships have traditionally had very high power requirements. For state operators, this means lower operating costs, but also reduced emissions, an increasingly important factor as state fleets are also subject to climate targets.
Although details about propulsion and fuel have not yet been published, energy efficiency could indicate a more advanced hybrid solution or improved propeller and hull design. Internationally, intensive development work is underway on electrification, battery support, and alternative fuels, also for icebreakers.
The First Such Order Secured by a Korean Shipyard
HD Hyundai Heavy Industries has succeeded in securing an order for a dedicated icebreaker from overseas, marking a first for a Korean shipyard.
In this bid, HD Hyundai Heavy Industries received consistently high evaluations across the board, including price competitiveness, delivery time, and technological capabilities. The icebreaker ordered is scheduled for delivery in 2029 and will perform icebreaking support, fleet operation support, towing operations, and ice management tasks in the Swedish Baltic Sea.
Furthermore, it is an achievement accomplished through a public-private partnership made possible by the active support of the Embassy of the Republic of Korea in Sweden and the KOTRA Stockholm Office.
Joo Won-ho, President of HD Hyundai Heavy Industries (Head of Naval Vessel and Medium-sized Ship Business), stated, “This icebreaker order signifies that the increased business capabilities resulting from the merger of HD Hyundai Heavy Industries and HD Hyundai Mipo have been recognized in the global market,” adding, “We will expand into new export markets in the special-purpose ship sector based on our technological prowess and business integration capabilities.”
