Norwegian oil and gas company Statoil has awarded Siemens a contract for the qualification, development, and fabrication of a compact compressor for wet and non-clean gas applications. The agreement covers a stringent testing programme of the completed compressor unit at the Statoil K-Lab facility in Norway during autumn 2008 under non-clean gas conditions, simulating real subsea environments.

The ECO-II centrifugal compressor concept is unique in that its seal-less and canned setup with an integrated electrical motor drive is designed specifically for non-clean applications such as sour, acid or toxic gas.
