6. EXTREME ENVIRONMENT

XiEn’s rugged EXTRIQ drives withstand the pressures, temperatures, and vibrations that result from deep-water operation

The underwater crafts are used for a variety of applications – from servicing deep sea oil rigs to performing important marine life research. As the subsea machinery goes all-electric, the manufacturers need drive technologies to power the thrusters that propel, maneuver, and stabilize the underwater equipment. XiEn’s EXTRIQ line of products, designed specifically for harsh environment, provides its submersible drives for the manufacturers of underwater equipment which can withstand the subsea conditions, including high pressure, all the while providing precise motion control.

Beyond the physical advantage, XiEn addresses the need for high-speed underwater thrusting with ultra-high voltage drives, thrusters’ start-up against water currents with advanced servo algorithms, and mandatory robustness for deep-water pressures and shocks. The drives meet Harsh Environment standards, as they can withstand mechanical shocks of up to 75G, vibrations of 20Hz-2000Hz (14.6 Grms), pressures up to 700 bar (the equivalent of 7000 m below sea level) and a temperature range of -40°C to 70°C.
