Floating Airbag Experts

SunHelm Marine delivers 140-ton buoyancy lifting airbags engineered with high-strength composites for extreme pressure/corrosion resistance. Modular designs scale to thousand-ton buoyancy solutions, critical for offshore wind transport, deep-sea aquaculture, and salvage operations.

Cold-optimized for Arctic/subarctic ports (e.g., Russia, Canada), our airbags retain flexibility below freezing to absorb ship impact energy, reduce hull stress, and ensure safe docking buffering in extreme low-temperature waters.

All buoyancy products are certified by international third-party organizations including BV, SGS, and ABS, ensuring reliable quality.

Since September 29, 2025, SunHelm has commenced production of EUDR-compliant marine airbags , becoming the first enterprise in China's industry to support this green initiative.

Backed by a professional team specializing in fluid dynamics calculations and engineering services, we provide comprehensive technical support from system design to field implementation.
