Variable Ballast

ISE’s Variable Ballast System provides underwater vehicles with precise buoyancy control, enabling dynamic changes in vehicle weight and trim during subsea operations. The system can vary buoyancy by up to 60 kg at depths of up to 5,000 m, supporting advanced mission capabilities such as seabed parking, controlled descent, and operational flexibility.

The system features an innovative 3D-printed titanium pressure sphere that minimizes weight and mechanical complexity while maintaining deep-sea performance. Custom pump assemblies provide reliable operation at extreme depths, while the use of seawater as the working fluid reduces environmental impact in the event of a leak.

Designed for integration with a wide range of underwater platforms, the ISE Variable Ballast System provides a robust and efficient solution for enhanced vehicle control in demanding subsea environments.
