Three years ago today, Lianyungang Port built and used its own pure electric tugboat, and started the first pure electric tugboat in China, the "Yungang Electric Tug No. 1", with a single button. With the sound of the loud whistle, the firm exploration of the development of the pure electric tugboat business was opened.
Today, three years later, the "Yungang Electric Tug No. 1" has delivered an excellent report card with 36 months of stable operation. As the first ship of "first trial", the most scenarios and maximum use and verification are the concentrated embodiment of the "pioneering spirit" of Lianyungang's pure electric tugboat.

The total number of operations was 4,831, with an average of 4.47 operations per day, and the highest number of operations per month was 211, with a utilization rate of 35.4%; the total operating time was 6,099 hours, with an average operation time of 1.26 hours per ship. The highest number of operations per day was 12, with an operation time of 14 hours and a power consumption of 84%. The longest continuous operation was 8 ships, with an operation time of 9 hours and a power consumption of 40%; the total power consumption was 1,596,216 kWh, with an average power consumption of 330 kWh per ship. Normal charging was 570 times, with an average charge every 1.89 days. The average cost of a single ship operation was only 330 yuan. At the current utilization rate of 23.5%, the pure berthing assistance condition actually reduced fuel consumption by a total of about 725 tons and reduced carbon oxide emissions by about 2,175 tons compared with conventional tugboats. During the three years, the ship operated normally, the power system battery voltage, current, SOC, insulation resistance, temperature measurement and monitoring were normal, the battery management system and energy management system were smoothly controlled; the propulsion system responded quickly, the motor transmission part was well engaged; the deck machinery was normal and had excellent performance.
Every day for three years, the "Yungang Electric Tug No. 1" has been running at full power in the vast harbor, pulling not only the merchant ships passing by, but also the exploration and construction of the entire "manufacturing, use, management and training" system of the pure electric tugboat business of Lianyungang Port.
Construction - "Building a national pure electric tugboat industry demonstration base"
"Build a good ship, train a team, cultivate an industry, and create first-class services" is the original intention of the shipbuilding business of Lianyungang Port Barge Branch. In order to further highlight its leading advantages in the field of pure electric tugboats, it will make every effort to complete the construction of the Lianyungang Port Pure Electric Tugboat Industry Demonstration Base, which can complete the construction and delivery of 8 pure electric tugboats each year, achieve increased volume and efficiency, and transform and upgrade. Use "the shipyard that understands shipowners best" to understand and build high-quality tugboats, use brand-new production capacity to welcome the signing of pure electric tugboat orders, and further strengthen and improve the Lianyungang Port pure electric tugboat brand.

Use - Achieving "zero emission" pure electric tugboat fleet to assist in port barge
"There is no perfect solution, but there is the most suitable solution." The performance characteristics of the pure electric tugboat fully match the range and rhythm characteristics of port tugboat operations.
The efficient, safe and environmentally friendly operation of the country's first "Yungang Electric Tug No. 1" and the world's largest horsepower "Yungang Electric Tug No. 2" have taken the lead in realizing the "zero-emission" tugboat crew working together in global ports, and the first company-wide realization of "carbon peak", achieving good operational economic benefits and industry demonstration effects, filling the gap in domestic high-power green and low-carbon port operation tugboats, and submitting an "internship report" for the pure electric "solution" for Lianyungang Port tugboats.

Management——Complete “full coverage of pure electric tugboat management”
The change of one word from "oil" to "electricity" has brought about an evolution in the nature of ship management. Lianyungang Port Barge Branch has compiled management systems and operation records such as the "Equipment Visualization Manual", "Work Log (Trial Operation)", "Repair and Maintenance Record Book", "Lithium Battery Charging Record Book", "Navigation Parameter Record Table", and "Shore-based Inspection Record Book" that are applicable to pure electric ships. The Equipment Support Center remotely monitors and guides through shipboard computers, and uses APP to view and monitor ship operating parameters in real time, effectively monitoring the ship's operating status. The Production and Dispatching Center scientifically formulates pure electric ship deployment plans based on ship power and operational expectations to ensure the safe operation of ships. Over the past three years, Lianyungang Port Barge Branch has brought management coverage with a full understanding of pure electric tugboats, and management coverage has brought confidence in the application of pure electric tugboat solutions.

Training——Having “complete teaching materials” and “practical training scenarios” for pure electric crew
"5-2=3" is a brand-new solution for zero-staffing in the engine room of a pure electric tugboat. The streamlining of personnel has brought about a significant reduction in human resource costs and maritime safety risks, but it also means an increase in the requirements for crew members. In order to "recharge" the crew, Lianyungang Port Barge Branch has compiled the first domestic crew training materials for battery-powered ships, "Battery-Powered Ship Crew Training Materials (Professional Training)" and "Battery-Powered Ship Crew Training Materials (Basic Training)". On the basis of complete theoretical learning, a "follow-up and follow-up" training plan was formulated to complete the "pre-job training" of pure electric tugboats in real ships and real situations. Through continuous exploration and summary of "pure electric crew" training, it has become the first unit in China with the qualification to train battery-powered ship crew members.
Lianyungang Port Barge Branch has paid tribute to the predecessors who have fired the starting gun for the development of the "pure electric tugboat" business with practical actions in the past three years. With a responsible attitude towards the development of the industry and the future of the business, it has built a complete service system for pure electric tugboats that is "finely made, well used, fully managed, and well trained."
Looking to the future, we expect that in the next three years, Lianyungang Port Barge Branch will continue to "do one thing well", work together with its peers in the world's barge industry, implement the "dual carbon" environmental protection strategy with practical actions, promote the construction of green ports, unfold a new picture of ecological priority and green development, and open up a new picture of intelligent innovation and new quality development.
