Variable Ballast

ISE’s Variable Ballast System provides a unique capability for underwater vehicles: the ability to vary buoyancy by up to 60 kg at depths of up to 5000 meters.

An innovative 3D printed titanium pressure sphere minimizes system weight and complexity while two custom made pump assemblies provide the power needed to operate at extreme depths.

This system utilizes seawater as the working fluid, minimizing environmental impact in the event of a leak or spill.
