The FKAB Marine Design L21 ammonia carrier Shenghang Yongle has been converted for ship-to-ship liquid ammonia fuel bunkering.
Led by Jiangsu Andefu Energy Development, FKAB, together with cargo handling supplier Gloryholder, provided the technical drawing documentation for the conversion.
The vessel is now the world’s first operational ammonia bunker vessel and has received the first ammonia bunkering class certificate. The achievement marks an important step in developing the infrastructure needed to support ammonia as a marine fuel.
While several ammonia bunker vessel projects have reached the design, feasibility or construction stage, the Shenghang Yongle has now progressed into operational readiness.
Originally designed as a flexible liquefied gas carrier, the vessel has been upgraded from a conventional ammonia carrier into a dual-purpose vessel capable of both transporting liquid ammonia and delivering it as fuel through ship-to-ship bunkering.
