According to China Classification Society (CCS), which is also part of the research project, the construction of the tug began on January 16, 2024.

The 39-meter-long ammonia/diesel-powered tug is equipped with two C-type liquid ammonia storage tanks, an ammonia-diesel dual-fuel engine developed by Dalian CRRC Diesel Engine Co., and an ammonia fuel supply system by COSCO Shipping Heavy Industry Technology (Weihai) Co.

Ammonia-fueled vessel and ammonia supply system designs were awarded approvals in principle (AiPs) from classification society ABS as well as CCS.

In the subsequent construction inspection of the ship, CCS will provide inspection services and technical support, work closely with the shipyard and participating parties, and lead the promotion of new clean energy represented by ammonia fuel in shipping.
