The Dalian Free Trade Zone is empowered by science and technology to accelerate the transformation and upgrading of green and low-carbon ports

Improving the green and low-carbon level of port container terminal operations is an important part of practicing the "dual carbon" strategy and building smart ports. The Dalian Free Trade Zone in Liaoning Province has taken the Container Terminal Company (hereinafter referred to as DCT) and the relevant logistics park in Dayaowan Port Area as pilot demonstrations to promote the whole process of container logistics business, put into operation pure electric unmanned container trucks, lay out and build rooftop photovoltaic power stations, continue to empower terminals to reduce carbon emissions, and actively contribute to the construction of Dalian smart port.

The "Dayaowan Smart Port 2.0" project, which has been completed and put into operation since December last year, provides a smart management system for DCT, realizes functions such as online business handling of the whole process of port customers, and reduces non-production downtime and energy loss caused by "running procedures". The unmanned container trucks in the terminal are all electrically driven, which can be charged for 1 hour and can operate continuously for 10-16 hours, which is more energy-efficient than the horizontal transportation mode driven by internal combustion engines. On the basis of automation, it has also achieved smart and green upgrades, adopted the operation mode of "self-generation and self-consumption, surplus electricity grid", installed more than 13,000 photovoltaic solar panels on the roof of the warehouse of the container terminal logistics park, and built 3 new box-type substations, with an annual power generation of more than 4 million kilowatt hours, promoting the continuous optimization of the port's energy structure.

Taking the intelligent environment as an example, DCT Terminal has set up 3 indoor and 1 outdoor environmental monitoring points to fully integrate the data of the five major environmental elements of the wharf, including water, electricity, air, meteorology, and tides, and carry out comprehensive perception and intelligent control on this basis to achieve energy conservation and emission reduction. Since 2023, DCT terminals have reduced carbon dioxide emissions by 3.3% year-on-year, oil consumption by 2.9%, and comprehensive emissions by 3.3% year-on-year.
