Solutions for deep diving, subsea energy and underwater mission operations — managing pressure, gas narcosis and decompression in the harshest aquatic environments.
Decompression procedures in saturation diving have matured over decades and DCS incidence is now low. The engineering requirement is measuring decompression stress in real time — giving dive supervisors the physiological evidence to set excursion intervals and oxygen levels, rather than treating the decompression table as the only signal that a profile was tolerated.
Respiratory Heat Loss in Heliox
Saturation diving substitutes heliox to eliminate nitrogen narcosis at depth. Helium conducts heat far more efficiently than air, so the gas that keeps cognition intact at 300 metres strips thermal energy with every exhalation — and at pressure, rising gas density amplifies that loss further. Saturation chambers run at 29–34 °C precisely because of this. Hot water supply to the suit is monitored; core temperature of the diver breathing that gas typically is not.
High-Pressure Nervous Syndrome
Below roughly 150 metres, hydrostatic pressure on the nervous system produces HPNS — tremors, cognitive slowing and EEG changes independent of gas mixture. It is the depth ceiling for direct intervention diving. Descent rate management and helium–hydrogen substitution can extend the operational ceiling, but HPNS remains the neurological constraint that sets the hard limit on how far a diver can go.
Platform Capabilities in This Domain
PLATFORM MODULES
CORE
CORE-S · Aqua is the structural platform for subsea operations — pressure architecture integrating hard-shell and semi-rigid barriers with modular interfaces for diving payloads and life-support systems.
PULSE
PULSE-S captures diver physiology directly — core and skin temperature, respiratory rate and gas consumption, cardiovascular load, and decompression stress measured on the diver, not inferred from the chamber.
PROVE
Kosmosuit Prove runs hyperbaric chamber and immersion validation using instrumented SYNHUM surrogates, generating physiological evidence across the pressure envelope without placing a diver at risk.
DEPLOY
Kosmosuit Deploy puts the system into ocean conditions — HELIOS autonomous platforms and SYNHUM field surrogates operating at depth for extended mission validation.
Pressure chamber and open-ocean trials for saturation and surface-supplied systems — instrumented surrogates replacing diver exposure during envelope-expansion testing. Explore PROVE →
