Medium Mooring Buoy-M1

By integrating wave sensors, meteorological sensors and hydrological sensors (optional) on the self-fixed buoy body, it can use Beidou, 4G or Tian Tong communication system to send back data.


The buoy body adopts CCSB structural steel ship plate, the mast adopts 5083H116 aluminium alloy, and the lifting ring adopts Q235B.


The buoy adopts a solar power supply system and Beidou, 4G or Tian Tong communication systems, owning underwater observation wells, equipped with hydrologic sensors and meteorological sensors.

High Quality

The buoy body and anchor system can be maintenance-free for two years after being optimized.


Now, it has been put into the offshore water of China and the middle deep water of the Pacific Ocean many times and runs stably.
