DNV grants AiP to HD Hyundai Mipo for ammonia dual-fuel gas carrier design

DNV has granted an Approval in Principle (AiP) to HD Hyundai Mipo Dockyard (HD HMD) for the design of an ammonia dual-fuel medium gas carrier (MGC) with a forward accommodation layout. The AiP was handed over at Gastech 2025 to D.J. Lee, Executive Vice President and Head of Initial Design Division and Detailed Design Division at HD HMD, by Vidar Dolonen, Regional Manager for Korea and Japan at DNV.

The concept shifts the crew accommodation block to the fore section, creating additional usable space on board. This enables integration of technologies such as carbon capture systems, alternative fuels, and other energy efficiency or emission reduction solutions. The arrangement also supports the installation of an ammonia dual-fuel propulsion system and allows flexibility for adopting future technologies in line with evolving environmental requirements.

“This innovative design reflects our commitment to delivering solutions that address customer needs and global sustainability targets. Working with DNV, we aim to accelerate the adoption of next-generation technologies for a greener maritime industry,” said D.J. Lee.

Vidar Dolonen noted the spatial challenges of new fuel and energy systems. “One of the challenges associated with alternative fuels and energy efficiency enhancing technologies is optimizing design for the space required for onboard installation. As the energy transition gathers momentum, we are seeing innovators like HD Hyundai Mipo work on finding ways to optimize their designs to maximize the economic potential of a vessel, while giving owners the flexibility to utilize the latest green solutions. We are very pleased to award this AiP to HD Hyundai Mipo and look forward to a productive and deepening cooperation,” he said.
