South Korean shipbuilder HD Hyundai Heavy Industries (HD HHI) has won a tender to build a next-generation icebreaker for the Swedish Maritime Administration (Sjöfartsverket), a public enterprise within the country’s transport sector.

The shipbuilding contract, valued at US$348.9M, was signed at the National Maritime Museum in Stockholm on 24 April.

Featuring Polar Class 4 (PC4) icebreaking capability and a diesel-electric propulsion system, the vessel is due for delivery in 2029. It is based on a joint Swedish–Finnish design developed in collaboration with the Finnish Transport Infrastructure Agency and design firm Railotech. The concept has already undergone validation through extensive ice tank and wind tunnel testing.

The yet-to-be-named newbuild will provide icebreaking support, fleet operations, towing services, and ice management in the Baltic Sea off Sweden. Larger than existing icebreakers, the vessel will be capable of breaking a channel up to 32 m wide, compared with the current 24 m, while reducing energy consumption by around 40%. It will measure 126 m in length and have a displacement of about 15,000 tonnes.

The timing is critical for Swedish infrastructure. The country’s existing large icebreakers, built in the 1970s and 1980s, are approaching the end of their operational lifespans. Furthermore, demand for icebreaking is increasing, driven in part by more severe winters and harsher sea ice conditions. Without icebreaking support, several ports in northern Sweden risk being closed for up to 130 days a year.

“Nine out of 10 goods exported and imported to and from Sweden are transported by sea,” said Sjöfartsverket director-general Erik Eklund, noting the vital role maritime transport plays in the country’s economic health. “Our icebreakers have served Sweden well for decades, but now need to be gradually replaced. This is an important step in securing preparedness and keeping ports open all year round,” he added.

The Norrköping-based administration currently operates five icebreakers: Ale, Atle, Frej, Oden, and Ymer. This new order is expected to be the first of several, with planning for further fleet renewals already underway.

The contract is a significant milestone for the South Korean maritime industry. By outcompeting established players from Finland and Norway, HD Hyundai has signalled its intent to become a major player in the high-spec Arctic shipping market.

Joo Won-ho, head of Naval and Medium Ship Business at HD HHI, noted that the order reflects global recognition of the group’s strengthened business capabilities through the integration of HD HHI and HD Hyundai Mipo.

“We will continue to expand new export markets in the special-purpose ship segment based on our technological capabilities and integrated business expertise," added Mr Won-ho.
