The “Qin Gang 28”, the first hybrid-powered tugboat in the Bohai Bay, has been put into operation at Qinhuangdao Port. It is expected to reduce diesel consumption by approximately 113.4 tons per year and cut carbon dioxide emissions by 355 tons annually. Currently, green and low-carbon operations have become the main mode of port production.
The “Qin Gang 28” is not only the first hybrid-powered tugboat of Qinhuangdao Port and the Bohai Rim ports, but also the first new energy tugboat in China with external fire-fighting capabilities. With a power of 4,400 hp (horsepower), the “Qin Gang 28” has an overall designed length of 37.5 meters, a width of 10.4 meters, and a depth of 4.7 meters. Its designed speed is not less than 12.5 knots, designed bollard pull is no less than 51 tons, and full-load displacement is 854.4 tons. It features one-click switching between diesel engine propulsion and electric motor propulsion modes, capable of meeting the requirements of assisting large ships in entering and leaving the port, as well as pushing and towing operations for berthing and unberthing.
The “Qin Gang 28” was built by Zhenjiang Shipyard , and the CSSC provided the full-ship power propulsion system. The vessel is equipped with a 1005kWh LFP battery system developed by Racern Technology. The battery system adopts a high-safety redundant energy zone design of 2 zones and 6 clusters, with multi-zone and multi-cluster battery parallel redundancy to fully ensure energy safety. The system is configured with Racern Technology’s latest generation of BMS, featuring a three-level management architecture of cell, providing all-round real-time protection for the safety of the battery system.
Compared with traditional tugboats, the “Qin Gang 28” innovatively adopts an oil-electric hybrid power configuration, boasting performance advantages such as zero emissions, low noise and low energy consumption when navigating within the port area. According to calculations, the vessel can sail at a speed of no less than 8 knots in all-electric mode, achieving “zero emissions” during navigation within the port area. It is expected to reduce light diesel oil consumption by about 113.4 tons per year. Based on the calculation that each liter of diesel saved reduces carbon dioxide emissions by 2.63 kilograms, the annual cumulative emission reduction reaches 355 tons.
