石油设备网讯 据世界石油网4月12日米兰报道，日本电产株式会社（尼得科集团）麾下的子公司尼得科ASI公司上个月与德国西门子天然气和电力公司签署了一项数百万欧元的合同，向位于俄罗斯北极亚马尔半岛上的北极液化天然气（LNG）-2项目的天然气液化厂提供变频驱动系统（VFDS）和电机。
尼得科ASI公司提供的电机技术规格使其能够在零下52℃的温度下连续工作，从而满足在北极圈恶劣气候环境中作业的特殊要求。
更具体地说，在获得压缩机供应商奖以后的尼得科集团已被选中提供：用于进气升压的压缩机，3台 37兆瓦电流源VFDS和3台同步电机，包括谐波过滤系统和用于危险区域安装的输入变压器；用于气化气体的压缩机，3台20兆瓦电压源PWM VFDS用来启动6台中压定速感应电动机，可在气温-52℃以下连续运行。
雄心勃勃的北极LNG- 2项目总价值为255亿美元，由俄罗斯最大LNG生产商之一的诺瓦泰克开发。这个项目涉及在俄罗斯通过GBS平台建造3个LNG厂，每个LNG厂具有660万吨LNG年产能，相当于53.5万桶/天。

Nidec ASI to supply VFDS for $25.5 billion Arctic LNG 2 project
Nidec ASI, head of the Nidec Industrial Solutions business platform belonging to the Nidec Group, signed last month with Siemens Gas and Power, a multi-million euro contract, for the supply of Variable Frequency Drives Systems (VFDS) and Motors for the Arctic LNG 2 project which will be used as part of the Natural Gas (LNG) liquefaction plants located in the Yamal peninsula in Arctic Russia. The technical specifications of the motors supplied by Nidec ASI make it possible to work continuously even at temperatures down to -52°C, thus meeting the special requirements needed to operate in the hostile and harsh climate of the Arctic Circle.
More specifically, following closely on the compressor vendor award, Nidec has been selected to provide: for Feed Gas Booster compressors, three 37MW Current Source VFDS and three synchronous motors, including harmonic filtering systems and input transformers for hazardous area installation; and for Boil Off Gas compressors, three 20MW Voltage Source PWM VFDS for starting six medium-voltage fixed-speed induction motors, designed for continuous operation at temperatures down to -52°C.
The ambitious Arctic LNG 2 project, with a total value of $25.5 billion, developed by Novatek, one of the largest producers of liquid natural gas in Russia, involves the construction of three plants for liquefying natural gas (LNG) via GBS (Gravity-based Structure) platforms, each with a capacity of approximately 6.6 million tons/year (MTPA), equivalent to 535,000 barrels/day.
