Hanwha Ocean has signed a shipbuilding contract with Taiwan's Yang Ming Marine Transport for six 13,650-TEU LNG dual-fuel container ships, worth approximately 1.55 trillion won. The order, announced Sept. 3, equals 12.1% of Hanwha Ocean's consolidated revenue last year and follows the two companies' first transaction just a year earlier. Construction will take place at Hanwha Ocean's Geoje shipyard, with deliveries scheduled sequentially through the second half of 2029. The vessels will feature Hanwha Ocean's in-house-developed high-manganese steel-based Type-B LNG fuel tank, a material that retains strength at temperatures as low as minus 163 degrees Celsius while offering greater cost competitiveness than nickel alloy steel or aluminum. The company said it will also apply its latest hull-form optimization technology to improve fuel efficiency and cargo capacity. The contract builds on Yang Ming's order last September for seven 15,880-TEU LNG dual-fuel container ships. Hanwha Ocean CEO Kim Hee-chul credited trust built through the earlier project for the follow-up order, while Yang Ming chairman Tsai Feng-ming said the deal reflects a solid partnership and shared commitment to a sustainable fleet. The Yang Ming deal comes two days after Hanwha Ocean secured an order for three very large gas carriers worth 477.8 billion won from an Oceania-based shipowner, bringing its two-day order total to 2.03 trillion won. So far in 2026, Hanwha Ocean has booked orders for 38 vessels, including 17 VLCCs, six LNG carriers and six container ships, with cumulative order value reaching about $7.07 billion, as demand shifts toward eco-friendly fleet replacement under tighter IMO regulations.
