South Korean Firm IOB Expands into Arctic LNG Shipping

IOB Co. Ltd., a newly formed South Korean ship manager, is stepping into the Arctic LNG shipping sector by taking control of four ice-class LNG carriers. Based in Busan, IOB has begun operating the 174,000-cubic-meter Arc4 vessels, North Moon, North Light, North Ocean, and North Valley, and plans to expand its fleet with three to six Arc7 vessels next year, followed by additional newbuildings from 2028.

The four Arc4 vessels were built by Hanwha Ocean for Japan’s Mitsui O.S.K. Lines in 2024 and 2025. Their ownership and management have recently shifted to a structure linking Russian gas producer Novatek with IOB, despite earlier EU sanctions on three of the ships for their involvement in Russian LNG trades. The EU lifted the sanctions after MOL provided assurances that the vessels would no longer transport Russian energy, though their transfer to a Russian-affiliated entity raises questions.

IOB’s expansion plans highlight its focus on Arctic LNG ship management, offering technical, marine, quality, safety, and crew-management services. The company claims 13 years of global LNG fleet-management experience, with its new Busan operation dedicated to ice-class vessels. Notably, several Arc7 LNG carriers remain stranded at Hanwha Ocean due to sanctions-related disruptions, presenting an opportunity for IOB’s planned expansion.

The development underscores South Korea’s growing role in Arctic shipping. Korean shipyards have built many specialized LNG carriers for Russia’s Arctic projects, while Busan is positioning itself as a logistics hub for Northern Sea Route trade. In August, PanStar conducted South Korea’s first commercial container trial via the route, signaling Busan’s ambitions as a gateway for Arctic trade.
