Description
Installation Subsea Buoyancy Modules Umbilical Buoyancy Solutions Surface And Subsurface Buoys
High-density, low water absorption floats designed for demanding subsea environments. Most products are custom manufactured to meet specific project requirements.
Syntactic Foam / Chemical Foam Subsea Buoyancy Modules For Marine Mining
Subsea Buoyancy Syntactic Foam
Subsea solid buoyancy material (syntactic foam) is a lightweight composite formed by embedding hollow microspheres in polymer matrices.
  • Low density (0.35-0.7g/cm³)
  • High strength (1-100MPa)
  • Minimal water absorption (<2%)
  • Excellent corrosion resistance
Engineered for Extreme Deep-Sea Environments
Syntactic Foam / Chemical Foam Subsea Buoyancy Modules For Marine Mining
Our high-performance syntactic foams are specifically designed for deep-sea applications, offering:
  • Lightweight construction
  • Exceptional strength-to-weight ratio
  • Superior corrosion resistance
  • Ultra-high pressure resistance (withstands depths exceeding 10,000 meters)
These subsea buoyancy composites are typically fabricated by lightweight fillers like hollow glass microspheres to reduce density, often combining reinforcing fibers (e.g., carbon fiber, glass fiber) with polymer matrices (e.g., polyurethane, epoxy resin).
Applications
Our buoyancy modules are widely used in:
  • Manned submersibles
  • ROV/AUV buoyancy systems
  • Subsea oil and gas pipelines
  • Deep-sea mining equipment
By reducing structural weight while enhancing durability, our syntactic foams extend equipment lifespans and improve energy efficiency in marine operations.
