HD Hyundai Heavy Industries Achieves 'World's First' Certification for Ammonia-Powered Ship Technologies

Approval in Principle from ABS for Ammonia Wastewater Treatment System and Toxic Hazard Zone Setting System
Paving the Way for Leadership in Eco-Friendly Ships

HD Hyundai Heavy Industries' newly developed safety and environmental technologies for ammonia-powered ships have become the first in the world to receive Approval in Principle (AIP) from the American Bureau of Shipping (ABS).

On September 10, HD Hyundai Heavy Industries announced that two of its technologies-the "ammonia wastewater treatment system" and the "toxic hazard zone setting system"-have obtained ABS Approval in Principle certification. These are core systems designed to meet safety and environmental regulations in the commercialization process of ammonia-powered ships.

HD Hyundai Heavy Industries recently announced on the 10th that it has independently developed the world's first ammonia-related wastewater treatment system and toxic hazard zone setting system for ammonia-powered ships, and has obtained the Approval in Principle (AIP) certification from the American Bureau of Shipping (ABS).

The ammonia wastewater treatment system developed by HD Hyundai Heavy Industries measures the ammonia concentration in the wastewater collected in the tank in real time and only allows discharge overboard if the concentration is within permissible limits. The toxic hazard zone setting system divides the ship into high, medium, and low-risk zones to prepare for potential leakage accidents during the operation of onboard ammonia propulsion equipment and the bunkering (fuel supply) process, and establishes necessary response protocols for each zone.

HD Hyundai Heavy Industries expects that this certification will strengthen the foundation for the commercialization of ammonia-powered ships and accelerate its entry into the global eco-friendly ship market. Due to the toxic nature of ammonia as a fuel, supplementary technologies are required to ensure safe utilization. Related international regulations have not yet been established.

A representative from HD Hyundai Heavy Industries stated, "This achievement demonstrates our technological capabilities in the field of eco-friendly ships," adding, "We will continue to focus on developing innovative technologies to lead the next-generation fuel market."
