Pressure Tolerant Technologies


Pressure tolerant systems are individual components embedded in flexible polymers. The assemblies are cast with a special vacuum technology enabling the components to work in a deep-sea environment.

In deep water, undersea systems are exposed to extremely high pressures. Conventional systems with components housed in pressure chambers are typically large, heavy, and expensive for any depths past a few hundred meters due to the requirements of strength, seal tightness, and corrosion resistance.

Kraken Power has developed an alternative to traditional pressure housings with its own pressure-tolerant technology. These pressure-tolerant systems (PTS) are working similarly to pressure-compensated systems where the components are exposed to hydrostatic pressure. However, the traditional compensation via liquid is replaced by incompressible elastomers such as silicone or polyurethane. As a result, the volume compensation via liquid is no longer necessary, i.e. an oil compensator is no longer required. A proprietary vacuum technique enables the encapsulating polymers to be used at depths to 6,000 meters.

Pressure-tolerant systems have a lower specific weight and a smaller volume in comparison to pressure or oil-compensated systems. They are corrosion resistant, require less maintenance and are thus cheaper to maintain.

Kraken Power has been working with this technology for many years, and through its acquired know-how, can now offer a variety of pressure-tolerant products and solutions for deep-sea applications and technology.
