Norway, Sept. 11 -- At Gastech 2025, DNV awarded an Approval in Principle (AiP) to Hanwha Ocean for its newly developed high-pressure Type B LNG fuel tank design for 16,000 TEU containerships.The new design increases the maximum design vapor pressure of the Type B LNG fuel tank from the IGF Code limit of 0.7 bar to 1 bar. This enhancement significantly extends the vapor holding time of the fuel tank, making it well-suited for Hanwha Ocean's standard 16,000 TEU containership. By extending vapor retention, the design also addresses the inherent limitation of Type B tanks compared to Type C, thereby improving overall fuel efficiency and operational flexibility.An Approval in Principle (AiP) is an independent assessment of a concept within a de...
