Description
Durable Subsea Observation Buoys High Buoyancy Corrosion-resistant Pherical floats

Subsea observation buoys are the component of the buoy system that provides buoyancy, ensuring the buoy maintains a stable attitude and position in the deep-sea environment.

Deep-sea observation buoys are widely used in marine scientific research, resource development, environmental protection, and other fields. Through sensors and data acquisition systems onboard the buoy, researchers can obtain real-time dynamic information about the ocean environment, including water temperature, salinity, current velocity, pressure, and light intensity. This data provides crucial support for marine scientific research, resource development, and environmental protection.

Durable Subsea Observation Buoy 0.3g/cm3-0.7g/cm3 Spherical Floats

The subsea observation float is an indispensable component of the buoy. Its primary function is to provide the necessary buoyancy, enabling the buoy to maintain a stable attitude and position in the deep-sea environment. Furthermore, the float must possess excellent corrosion resistance, pressure resistance, and durability to withstand the complex and variable currents, water pressure, and temperature conditions of the deep-sea environment.


The subsea observation float is a key component of the deep-sea observation buoy. By providing buoyancy, maintaining stable attitude, and adapting to the deep-sea environment, it provides crucial support for marine scientific research, resource development, and other fields.

Subsea buoyancy material

Solid buoyancy material is a low-density, high-strength porous structure, serving as a crucial counterweight for underwater equipment. This product is a solid compound formed by physical and chemical reactions between an inorganic lightweight filler and an organic polymer. Underwater exploration systems constructed with this high-performance solid buoyancy material not only enable greater dive depths, increase payload, and reduce energy consumption, but also maintain stable underwater operation, making it an indispensable component of 21st-century deep-sea diving technology.
