China’s first super-large three-anchor buoy integrated observation platform was listed and officially put into operation
China News Service, Qingdao, January 16th (Reporter Hu Yaojie) The Institute of Oceanology, Chinese Academy of Sciences announced on the 16th that China’s first super-large three-anchor buoy integrated observation platform with long-term, fixed-point and intelligent profile observation functions (“Three Anchor Platform” for short) was successfully deployed in the East China Sea and officially joined the observation array of the East China Sea Ocean Observation and Research Station of the Chinese Academy of Sciences Offshore Ocean Observation and Research Network. The operation of this facility puts an end to the history of the lack of long-term, fixed-point, and real-time profile water observation facilities in the offshore waters of China, enhances the network observation capabilities of the East China Sea Station, and increases the richness of observation parameters, which will provide more powerful marine scientific research.

According to the introduction, the three-anchor platform is currently the first domestic comprehensive marine observation and test platform with the largest diameter, the most complete observation parameters, and the highest degree of intelligence in China. The difficult problem of long-term, fixed-point and continuous acquisition is an innovative application project in observation technology.
It is reported that the basic structure of the three-anchor platform is composed of a central main buoy body, three peripheral protection buoys and supporting mooring systems, which effectively solves the problem that traditional single-moored buoys are easy to observe underwater profiles. Causes equipment entanglement problems. The intelligent judgment function of the triple anchor platform is also a major innovation. In severe weather, when the wind, wave, and current values exceed the safety threshold, the profile observation equipment can be safely recovered, and it can be automatically put into operation when the sea conditions improve.
Because the three-anchor buoy integrated observation platform adopts the special mooring method of the three-anchor mooring system, it is very difficult to deploy. To this end, all technicians arrived at the site five days in advance to prepare for deployment, including material inventory, anchoring connection, sensor calibration and detection, winch debugging and safety system inspection, etc. There were 61 deployment procedures alone.
On the day of deployment, two engineering ships towed the three-anchor buoy integrated observation platform, protection buoys and related materials after more than 10 hours of towing about 40 nautical miles to the designated sea area, after nearly 14 hours In the end, the two construction ships followed the coordinated dispatch of the deployment plan and successfully completed the deployment of the entire system. Since then, the three-anchor buoy integrated observation platform has been officially included in the observation array of the East China Sea Ocean Observation and Research Station, and long-term, fixed-point, real-time profile observation data acquisition has begun.
The development of the three-anchor platform was supported by the Marine Science Research Center of the Chinese Academy of Sciences, the Ministry of Finance’s special funds for repair and purchase, the equipment development project of the Chinese Academy of Sciences and the National Natural Science Foundation of China. The development and construction of the platform was supported by Shandong Province Assistance and support from the Institute of Marine Instruments and Meters of the Academy of Sciences, Jiangsu Xinhua Navigation Mark Factory, and the Institute of Semiconductors of the Chinese Academy of Sciences.
