Innovative high-voltage switchgear key to subsea compression

Power EquipmentSubsea Switchgear Electrical System DesignElectromagnetic CompatibilityAuxiliary Power SuppliesProtection SystemInterface EngineeringThermal EngineeringMechanical DesignFabrication EngineeringAvailability StudiesThe pilot subsea gas compressor motor is rated 12.5 MW and is used together with a 400 kW pump. The long tieback makes subsea power distribution necessary. The equipment in the CBM is 36 kV class and the subsea system voltage is 22 kV. Auxiliary power is provided via a transformer and is backed up by an uninterruptible power supply (UPS) in a separate subsea module. Circuit breakers and protection devices that could operate within an oil-filled, pressure-compensated environment are not yet commercially available. The switchgear is in an enclosure that provides a 1-atm pressure environment. Dry nitrogen fills the enclosure. Its physical properties are close enough to air to allow standard electrical equipment to be used. The high-voltage (HV) circuit breakers are proven 36 kV class air-insulated devices. These circuit breakers are also used in arc furnace applications which are characterized by their severe switching duties. The other HV devices used are proven 36 kV class magnetic c...Get price
