Designed specifically for ROV and AUV underwater vehicles, providing stable and reliable buoyancy support in deep-sea environments.
Made of closed-cell / syntactic foam with high compressive strength, low water absorption and excellent hydrostatic pressure resistance.
Lightweight structure with high buoyancy efficiency, corrosion-resistant and durable for long-term underwater operation.
Can be processed into blocks, panels, spheres or custom shapes to fit different ROV/AUV structures and installation requirements.
Suitable for various water depths, widely used in offshore engineering, underwater inspection, marine survey and subsea operations.
