The design comprised of 2+1 Avon Compressors (45,000 installed HP) Pressure 27– bar g. Flow 150 M MSCFD. IMEG’S RESPONSIBILTY — IMEG’s brief extended to examining features of the design that might prevent satisfactory operation of the station under specific conditions and to making recommendations for corrective changes in the design. ________________________________________________________________________________________________ · CLIENT / PROJECT HISTORY — NADYMEG (for Komsomolsk-Na-Amure Oil Refinery). The refinery at Komsomolsk has a capacity of 6 m.t.a. but is in need of upgrading and rehabilitation. It obtains crude for Okha, Sakhalin Island, by pipeline 650km to the north. PROJECT DESCRIPTION — A review of two alternative routes for exporting 2.8 m.t.a. of refined products from the Komsomolsk Refinery. The products proposed for export are diesel, gasoline and kerosene. The alternatives are either to follow the existing crude oil line from Sakhalin and construct a new jetty and terminal at De Kastri, or adopt a new pipeline route to Vanino and construct a new storage terminal, but use the existing jetty. IMEG’s RESPONSIBILTY — A technical report was prepared in 1995 on the concept that a 324km multi-products pipeline to DE Kastri with four pump stations including one to Kosomolsk, a tank farm and loading terminal is the more economic solution. ________________________________________________________________________________________________ · CLIENT / PROJECT HISTORY — NADYMEG (for GAZPROM). The Yamal Peninsular in north western Siberia contains vast reserves of natural gas. Figures in excess of 10 Trillion Cubic Metres of proven reserves have been cited with the likelihood of probable reserves being well in excess of this. The Russian gas company Gazprom has developed plans for exploiting this huge resource by building a pipeline transmission system to carry the gas to markets in Europe. This development will be a massive undertaking which will provide a significant proportion of Russian and European energy requirements well into the next century. PROJECT DESCRIPTION — Initial Section of Yamal Peninsular to Europe Pipeline: * Period 1995 * Design throughput of 9285 M MSCFD * 90km of 3 x 56” diameter gas pipeline IMEG’s RESPONSIBILITY — Personnel form IMEG examined the terrain and assessed the difficulties that will be encountered un constructing this section of the pipeline.
