Converteam motors to drive compressors for WEPP pipeline

World Pipelines,


Converteam has been awarded a new contract for nine Variable Speed Drives Systems with PetroChina for the West-East Gas Pipeline Project (WEPP) which is one of the biggest infrastructure projects in China. With this new contract, Converteam reinforces its presence in the Chinese Oil & Gas market.

The first part of the WEPP is a 4000 km long pipeline, which is capable of transporting 17 billion m3 of gas annually from Lunnan in Xinjiang to Shanghai. Natural gas transported by the pipeline is used for electricity production in the Changjiang River Delta area.

Construction of the second part of the WEPP started in February 2008. The pipeline has a total length of 9102 km, including 4843 km of the main line and eight sub-lines and will run from Khorgas in Northwestern Xinjiang to Guangzhou in Guangdong and Hong Kong. Up to Guangzhou, it will be parallel and interconnected with the first west-east pipeline. The capacity of the second pipeline will be 30 billion m3 of gas annually.

Converteam will provide nine Variable Speed Drive Systems to run compression trains supplied by GE Oil & Gas for the WEPP II project. Each set will mainly consist of a transformer, a 2-Pole Turbo synchronous motor ranging from 15 MW to 18 MW at 4800rpm driven by a PWM (Pulse Width Modulated) 3-level MV7000 high performance drive. This solution with no gearbox improves the overall drive system efficiency and reliability. In particular by removing the gearbox, Converteam also reduces the footprint of the system significantly and the need for lubricating oil, thus limiting the environmental impact.
