Description
Subsea Energy Solutions Manufacture Custom Subsea Syntactic Buoyancy Modules for use with ROV / AUV Vehicles
High-density, low water absorption floats designed for demanding subsea environments. Most products are custom manufactured to meet specific project requirements.

The subsea buoyancy material is mainly used underwater. Based on its characteristics of low density and high pressure resistance, it mainly provides the required buoyancy for underwater operation equipment. Spray coating or protective layer treatment can be applied to the surface as required. Often manufactured and processed into floats, buoys and other counterweight products. It can also be directly machined into product parts.

It can not only meet the mechanical requirements of the product structure, but also greatly reduce the product weight and other functions. The application of this material realizes the functions that are difficult for metal structural parts to realize. At present, it has been used in underwater deep submersibles, underwater robots, etc., and can be used safely at depths of several thousand meters underwater.

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
OEM ODM Subsea Energy Solutions High Density With ROV / AUV Vehicles
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.
