ABS awards AiP for selective catalytic reduction in ammonia-fueled ships

ABS has issued an approval in principle (AiP) to HD Korea Shipbuilding & Offshore Engineering (KSOE) and HD Hyundai Heavy Industries (HHI) for its ammonia reductant supply system for selective catalytic reduction (SCR) in ammonia-fueled ships.

According to ABS, the system utilizes the ammonia carried on board as the SCR reductant to remove NOx from emissions as opposed to the urea used in traditional diesel propulsion. In addition, the AIP includes a plan to safely treat toxic ammonia gas generated during operation, including a configuration that can use ammonia Boil-Off Gas (BOG) and purge gas generated from an ammonia fuel supply system as an SCR reductant.

ABS has always been a safety pioneer, so we are well placed to tackle the challenges on board and ashore presented by ammonia’s toxicity and flammability. ABS is committed to leading the industry in supporting ammonia’s safe adoption at sea

… said John McDonald, ABS President and COO.

We are pleased to have received the world’s first approval in principle (AIP) from ABS and LISCR for our technology, which aims to improve the safety of ammonia-fueled ships and reduce the operating costs for shipowners.

… said Sung-Joon Kim, Senior Executive Vice President and CTO at HD KSOE.

Seung-Ho Jeon, Senior Executive Vice President and CTO at HD HHI stated that considering the recent tightening of environmental regulations, ammonia is expected to become a mainstream alternative fuel in the future. Accordingly, the development of ammonia-related technology will be actively developed, and HHI and KSOE are also working on the development of ammonia-related technology, Seung-Ho Jeon suppled. The newly developed ammonia-reducing agent supply system is one of the results of these technological development efforts and is expected to contribute to the efficient operation of ammonia carriers, Seung-Ho Jeon concluded.

As a leader in innovation and decarbonization, we at the Liberian Registry are very proud to join our partners in supporting this pioneering technology. This AIP is a significant step forward in the implementation of zero-carbon fueled vessels

… commented Alfonso Castillero, CEO of the Liberian International Ship and Corporate Registry (LISCR).

Meanwhile, ABS has also awarded two more approvals in principle (AiPs) to HD Hyundai Heavy Industries (HHI) and HD Korea Shipbuilding & Offshore Engineering (KSOE) for two new solutions that support autonomous navigation.
