DNV has awarded an Approval in Principle (AiP) to Zhoushan Changhong International and CIMC ORIC for a new 21,700 TEU multi-fuel ready ultra-large container ship design developed in partnership with MSC. This AiP marks another significant milestone in advancing next-generation, zero-carbon mainline container shipping.
The proposed 21,700 TEU container ship design enables the shipyard to accommodate an owner’s varying preferences for alternative fuels. In addition to the widely utilized LNG engines, different engine technologies, including the latest generation of ammonia-fueled main engines are now available to be integrated into the design.
One major challenge is the tank system, as no combined solution exists for storing both LNG and ammonia in the required quantities. This challenge was addressed by developing an oversized, specialized Type C tank for ammonia, positioned between the commonly used Type B/C or membrane LNG tank technologies.
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. (....)
