【Ten Years of Great Progress in Chemical Engineering Technology】087-2023: Trial operation of China’s first megawatt-class floating wave energy generation device
Thread Content
Ten years of rapid development in chemical engineering technology; praise for China’s prosperity and strength. This is just a starting point to encourage more people to get involved, making discussions even more lively. HaiChuan becomes even better with your participation – we welcome everyone to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On June 14, 2023, China’s first domestically developed megawatt-class floating wave energy generator, named “Nan Kun,” was put into trial operation in Zhuhai, Guangdong. This marks the official entry of China’s megawatt-class wave energy generation technology into the stage of practical application. It is reported that the total floor area of the entire facility exceeds 3,500 square meters, with a weight of 6,000 tons. Up to 24,000 kWh of electricity can be generated per day, which is equivalent to the daily energy consumption of 3,500 households. Liu Shi, chief technical expert at Southern Power Grid Power Technology Co., Ltd.: This system consists of a semi-submersible platform, a hydraulic system, a power generation system, a control system, and an anchoring system. We use semi-submersible platforms to \"absorb\" waves, and then, through our independently developed power conversion system, achieve three-stage energy conversion from wave energy to hydraulic energy and finally to electrical energy.

The “Nan Kun” wave energy power generation platform is set to be towed out to sea for operations, with the ship “Deyuan” serving as the main tug, assisted by the ships “Haigang Xiaotuo 7”, “Haigang Tuo 3” and “Sui Gang Yin 11”. It is planned to be towed from the dock at the Dongjiangkou plant of Guangdong COSCO Shipbuilding Co., Ltd. on June 7, 2023. The maximum towing length is about 300 meters, the maximum width is about 88 meters, the height above the water surface is 29.6 meters, the draft is 6 meters, and the towing speed is about 5 knots. It is expected to enter the main channel at 05:30 from the Dongjiang Estuary, pass over the Humen Bridge at 09:30, pass by buoy 42# at 12:30, and pass Ma Youshi at 16:30. At that time, one-way traffic control measures will be implemented for navigation on the section from the plant’s dock to Mayoushi, prohibiting other vessels and tug fleets from meeting or overtaking each other. Upon departure, patrol boats are deployed from the factory dock to Mayoushi to ensure security along the route; ships passing by must follow the on-site instructions to maintain safety.
