The first dual-fuel (LNG/Marine Oil) 6500HP ASD (Azimuth Stern Drive) tugboat being built for Ningbo-Zhoushan Port was successfully launched by Jiangsu Zhenjiang Shipyard (Group) Co. Ltd on December 25, 2018. The port is the busiest in the world in terms of cargo tonnage.
The vessel fully shows the development concept of low carbon, green and environment protection in terms of energy saving and emission reduction.
Driven by dual-fuel engines, the vessel can realize the exchange between fuel oil and LNG, and the fuel substitution can be up to 90%.
Operating in gas mode, the vessel can reduce 50% emission of SOX, 98% emission of particle matter, 80% emission of NOX and 22% emission of CO2.
The dual-fuel ASD tugboat is an ASD engineering demonstration of upgrading and replacing vessels in China.
