Norske Shell sanctions Ormen Lange: subsea compression tests

From the circuit-breakers, LV power is supplied to the USP modules. Each circuit breaker feeds two UPS modules which in turn supply the LV power to all LV consumers, including control power to the VSDs and power to the control system and actuators. The LV consumers also include the magnetic bearings...

Zusammenfassung:	From the circuit-breakers, LV power is supplied to the USP modules. Each circuit breaker feeds two UPS modules which in turn supply the LV power to all LV consumers, including control power to the VSDs and power to the control system and actuators. The LV consumers also include the magnetic bearings which are used in the compressors instead of standard bearings requiring lubrication.
