# DNV Validates Hanwha Ocean’s Advanced LNG Tank Technology for Major Containerships<\/p>\n
DNV has granted Approval in Principle to South Korean shipbuilder Hanwha Ocean for a high-pressure Type B liquefied natural gas fuel tank design intended for 16,000 TEU containerships. The recognition was announced at Gastech 2025, a major energy conference, validating the company’s technical approach to LNG fuel containment on large-capacity container vessels.<\/p>\n
The award reflects the maritime industry’s accelerating transition toward LNG propulsion as a compliance mechanism for stricter environmental regulations. As shipping faces increasingly stringent emissions requirements, LNG has emerged as a primary alternative fuel, with major container lines ordering dual-fuel vessels. Type B tank designs, which utilize independent tanks with secondary barriers, represent one of the technical pathways for LNG fuel storage. DNV’s approval signals that Hanwha Ocean’s design meets international safety and technical standards required for classification and regulatory acceptance.<\/p>\n
For the containership sector, validation of efficient LNG tank designs is significant given the economic pressures on container operators. Improved tank technology could enhance fuel capacity or cargo space efficiency on standard-sized vessels. Hanwha Ocean’s development positions the builder competitively as container lines continue fleet decarbonization programs. The approval establishes a foundation for potential retrofit applications and new construction orders, while underscoring South Korea’s continued dominance in advanced LNG carrier design and construction.<\/p>\n","protected":false},"excerpt":{"rendered":"
