Norway, Dec. 3 -- DNV has awarded an Approval in Principle (AiP) to the joint consortium of MSC, Zhoushan Changhong International, and CIMC ORIC for a new 21,700 TEU ammonia-dual fueled ultra-large container ship design. The AiP is another milestone in the development of next-generation, zero-carbon mainline container shipping.The proposed 21,700 TEU container ship integrates the latest-generation of ammonia dual-fuel main engines alongside oversized C-type ammonia tanks. The hull design, with a new vertical bow, optimized stern, and hull lines, alongside low-resistance coatings, high-efficiency propellers, and energy-saving hydrodynamic features, targets improved fuel efficiency, with validation through CFD simulations and model tests.DNV'...
