Classification society ABS introduced it issued an approval in precept (AIP) to South Korea’s HD Korea Shipbuilding & Offshore Engineering (KSOE) and HD Hyundai Heavy Industries (HHI) for his or her ammonia reductant provide system for selective catalytic discount (SCR) in ammonia-fueled ships. Representatives from each corporations and the Liberian International Ship & Corporate Registry (LISCR) met at this week’s Gastech convention in Singapore for the AIP presentation.
The system makes use of the ammonia carried on board because the SCR reductant to take away NOx from emissions versus the urea utilized in conventional diesel propulsion.
In addition, the AIP features a plan to soundly deal with poisonous ammonia gasoline generated throughout operation, together with a configuration that may use ammonia boil-off gasoline (BOG) and purge gasoline generated from an ammonia gasoline provide 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,” stated John McDonald, ABS president and COO.
“After the 80th MEPC, there is a lot of interest in zero-emission ships that use ammonia as fuel. 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. We will continue to develop ammonia-fueled ships that are the best for our customers and look forward to working with ABS and LISCR,” stated Sung-Joon Kim, senior govt vice chairman and CTO at HD KSOE.
“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. 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,” stated Seung-Ho Jeon, senior govt vice chairman and CTO at HD HHI.
“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,” stated Alfonso Castillero, CEO of the Liberian International Ship and Corporate Registry (LISCR).
