To achieve its goal of sustainable maritime transportation, China has initiated the construction of two of the world's largest electric container ships. These vessels, with a capacity of 740 twenty-foot equivalent units (TEUs), are set to revolutionize coastal container ship operations. They produce zero emissions and operate on pure electric propulsion. They also represent a significant step forward in the country's commitment to environmental conservation.

Independently designed by the Shanghai Merchant Ship Design and Research Institute (SDARI), a subsidiary of the China State Shipbuilding Corporation (CSSC), the ships were commissioned by Ningbo Ocean Shipping and will be constructed by Jiangxi Jiangxin Shipbuilding Corporation.

Measuring 127.8 meters in length and 21.6 meters in width, these vessels are tailored for domestic coastal navigation, specifically targeting a route between two ports in Zhejiang province, one in Ningbo, the other in Jiaxing's Zhapu town.

Once completed, each ship will have the capability of carrying a load exceeding 9,000 tons. With four cargo holds and seven hatches designed without covers, these ships are set to streamline loading and unloading processes, as well as berthing and departure times, thus improving efficiency.

The ships feature advanced technologies, including an electric propulsion cabin at the stern and a wind resistance-reducing superstructure at the bow to minimize vibration and noise. Powered by 10 box batteries totaling around 19,000 kilowatt-hours, the vessels incorporate a multi-level battery management system that ensures safety by isolating batteries from living spaces and cargo areas.

Furthermore, the ships are equipped with lightweight lashing bridges, a fall and collision prevention platform with a photovoltaic system for renewable energy generation, and the ability to maintain effective propulsion even in fault mode. The vessels can swiftly recharge at ports using high-voltage shore power stations or have their batteries replaced via lifting mechanisms.

The ships will also feature intelligent system integration platforms that enable real-time monitoring of external surroundings, route planning, unmanned driving, and autonomous collision avoidance. A shore-based operation and maintenance center will facilitate the remote monitoring and control of the equipment on both ships.
