China: LR issues AiP to NACKS for 16,000 TEU ammonia-fuelled container ship design

14 Oct 2022

Chinese shipyard Natong COSCO KHI Ship Engineering Co., Ltd. (NACKS) on Tuesday (11 October) received an Approval-in-Principle (AiP) from classification society Lloyd’s Register (LR) for a 16,000 TEU container ship design that is able to consume ammonia as a bunker fuel, according to local media.

The AiP paves the way for potential construction of the vessel by NACKS, a joint venture between China Ocean Shipping (Group) Company (COSCO) and Kawasaki Heavy Industries Ltd. (KHI), and Hudong Heavy Machinery Co., Ltd., a subsidiary of China State Shipbuilding Corporation.

LR, NACKS and Hudong Heavy Machinery have held risk assessment discussions for the ammonia-fuelled container ship design since the start of 2021.

Topics discussed included properties of ammonia fuel itself, such as flammability, high toxicity and corrosiveness.

The layout and material selection of ammonia bunker fuel tanks, positioning of ventilation shafts, leak detection of double walled pipes, fire protection from ammonia leakage, layout of the ammonia bunkering station, were amongst other issues considered.

The three parties fully considered the potential risks of the design, evaluated the possibility and severity of various risks, and provided solutions for future real-world implementation.
