The upgraded starting CU successfully operates as a part of the gas turbine power plant of East-Perevalnoye field

16 March 2019

Exactly 6 months ago, September 16, 2018 at the gas turbine power plant of East-Perevalnoye field, which is being developed by the Kogalymneftegaz TPE (LUKOIL-West Siberia), the putting of starting gas compressor unit (CU) of Enerproject took place.

Previously, this CU was in long-term storage at the Gezh field. After movement to other facility, the unit was upgraded taking into account the changed operating conditions. This task was solved by service specialists of ENERGAS Group – the official partner of the Swiss company Enerproject SA in Russia.

Engineers of ServicENERGAS LLC have carried out restoration work, upgraded the oil system, and replaced the main component of the unit, a screw oil-filled compressor. The new aggregate is additionally equipped with a system for monitoring the temperature of the sliding bearings and a system for monitoring the axial shear of the compressor screws.

There was installed new software, connected and configured automated control system of CU. Local ACS is integrated with the upper level of the APCS of the gas turbine power plant.

The commissioning of gas-booster equipment was preceded by a start-up activities, own (individual) tests and 72-hour comprehensive testing as a part of the GTPP-28. Under the terms of the contract, the project was implemented as soon as possible.

Six months of successful operation confirm the quality of performed works. The upgraded CU functions in a routine mode, without any complaints.

Compressor unit with capacity of 2,000 m3 / h provides final treatment, compression and supply of associated petroleum gas under pressure of 1.6 ... 1.8 MPa to the starting Ural-4000 power unit, made on the basis of the GTU-4P gas turbine unit with capacity of 4 MW.

The main generating equipment of the GTPP-28 consists of four Ural-6000 power units (based on GTU-6P) with capacity of 6 MW each. The Ural-4000 and Ural-6000 were designed and manufactured by the Perm engine-builders: the companies UEC-Aviadvigatel and UEC-Perm Motors.

The gas turbine power plant has been operating since March 2018. The new facility solves the problem of energy shortages and provides rational use of associated gas at the East-Perevalnoye field. The planned amount of APG recovery as a fuel for the GTPP is 65 million cubic meters annually.

REFERENCE. The East-Perevalnoye oil and gas field is the most distant deposit of the Kogalymneftegaz TPE; from Kogalym to it more than six hundred kilometers. Compared with other license areas of the enterprise, this field is rather young. It was opened in 1990 and put into operation in 1995.
