HD KSOE’s Ammonia Vent Treatment System Receives ABS and LISCR Approval

HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has received approval in principle from ABS and the Liberian International Ship and Corporate Registry (LISCR) for its advanced ammonia vent treatment system.

The system incorporates compact scrubbers designed to treat ammonia fuel released during purging, ensuring concentrations remain within safe levels before being discharged through the vent mast. HD KSOE noted that the design also reduces wastewater generation. ABS conducted design reviews in line with class requirements and IMO Interim Guidance.

“With our deep insight into the safety aspects of ammonia and advanced treatment technologies, we are supporting innovative clients like HD KSOE in developing equipment to accelerate the maritime industry’s journey to low or no carbon emissions,” said Patrick Ryan, ABS Senior Vice President and Chief Technology Officer.

“This certification from ABS strengthens HD KSOE’s technology portfolio for eco-friendly equipment,” said Young-Joon Nam, head of the SD Business Division at HD KSOE. “We will continue to develop unique technologies and lead the global market for eco-friendly ships.”
