Deep-Sea Solid Buoy

🌊 FLOAT X™ Deep-Sea Solid Buoy

High-Performance Buoyancy Solution for 300 – 6000 m Ocean Depths

Overview

The FLOAT X™ Deep-Sea Solid Buoy is an advanced, pressure-resistant float designed for deep-water operations up to 6000 meters. Built with closed-cell solid 

syntactic foam, it provides reliable buoyancy, minimal water absorption, and customizable shapes and sizes to meet demanding subsea engineering requirements.

Ideal for oceanographic research, ROV/AUV systems, underwater structures, and deep-sea exploration, FLOAT X™ ensures stability, durability, and long-term 

performance in the harshest marine environments.
