HMS Group manufactures compressor equipment for NOVATEK’s Arctic Cascade LNG production technology

Kazancompressormash (a part of the HMS Group) has completed testing of the main gas compression system manufactured for NOVATEK’s “Arctic Cascade” liquefied natural gas (LNG) production technology. The system is designed to operate in the natural gas liquefaction complex of the 4th stage of Yamal LNG project.

The gas compression system was developed at NIIturbokompressor (a part of the HMS Group) as an integrated compressor unit consisting of three centrifugal compressors designed to handle three process gases (methane, nitrogen and ethane). All three compressors are driven by a single Russian-made 25 MW gas turbine through a multi-shaft gearbox with one input and three output shafts. One of the compressors is designed as a multi-shaft unit of five compression stages.

This solution, implemented for the first time worldwide, makes possible to reduce the mutual thermodynamic impact of the compression stages and significantly reduce overall dimensions and mass of the entire compressor system of the LNG production complex. All the equipment is designed and manufactured in accordance with the requirements of API standards and is completed with a local automatic control system.

The engineering, manufacture, and subsequent complex procurement of the gas compression system by Kazancompressormash results from the HMS Group’s hands-on involvement in the import substitution programs and the development of the domestic process-related equipment for Russian LNG projects.

HMS Group is one of the leading pump, compressor and modular oil-field equipment manufacturers for the oil and gas, energy, housing and public utilities, and water utilities sectors in Russia and the CIS as well as a fast developing engineering company performing a wide range of design, construction, installation and commissioning works for integrated development of oil and gas extraction, and water facilities. HMS Group’s global depositary receipts (“GDRs”) are listed under the symbol “HMSG” on the London Stock Exchange.
