The first Russian gas-turbine unit GTA-8 designed by United Engine Corporation (a Rostec State Corporation company) for oil and gas platforms can be effectively used to develop the Russian Arctic. Its design includes solutions that are unique for domestic engine-building and allow the unit to be applied with the maximum effectiveness in the severe environment of the Extreme North.

GTA-8 can be used as part of gas-turbine electric power stations of oil and gas platforms for drilling, extraction, processing and storage of hydrocarbons, as well as part of heat power stations of seaside industrial and municipal facilities for heat and electricity production.

Corrosion-resistant materials in the design of GTA-8 allow its application as part of power generating units operating in regions with a high content of salt in the air, which fully meets the requirements for hardware used within offshore platforms of the Arctic shelf. The marine duel fuel gas-turbine engine E70/8RD serving as a basis for the development of GTA-8 can survive at an outdoor temperature of minus 55ºС, which makes its operation possible under arctic conditions. The GTA-8 design developer is Rybinsk UEC-Gas Turbines (UEC’s leader in the production of power supply and gas-compressor units and in the package construction of power generating facilities). E70/8RD was designed by UEC-Saturn (also located in Rybinsk).

“The task assigned by the President of the RF and the Government of the RF and related to the full-scale development of Arctic oil-gas fields opens possibilities for this line of UEC’s business and for the delivery of marine gas-turbine units and electric power stations to customers”, – says Sergey Mikhailov, Deputy General Director – Head of UEC’s Power Generating and Industrial Programs Division. 

Pursuant to the import substitution policy, it is planned to use main equipment of domestic manufacturers and suppliers in GTA-8 and GTA-8-based solutions.

The time between overhauls of GTA-8 is 25 thousand hours, the authorized life is 100 thousand. The brake efficiency of the GTE in stationary conditions is 32.9%.

In prospect there is a plan to develop marine gas-turbine units with a capacity of 20, 25 and 31 MW.

The GTA-8 was designed on the basis of the development marine gas-turbine electric power generator SGTG-8. The core of SGTG-8 is the marine duel fuel gas-turbine E70/8RD based on the high-efficiency unified gas generator intended for next-generation engines, tested within the GTD-4/6.3/10PM (industrial) and M75RU/M70FRU (marine) gas-turbine engine family. The designer of SGTG-8 is UEC-Saturn.

The first Russian commercial marine GTE E70/8RD, the distinctive feature of which is operation on two types of fuel, is designed to be used as part of main marine gas-turbine units, to supply power to vessels, offshore platforms and industrial facilities in near-shore zones. The acceptance tests of the engine were completed successfully by UEC-Saturn in 2012, it is ready for series production. E70/8RD is approved by the Russian Maritime Register of Shipping.

The design of the engine and its systems (automatic control system, ignition system, fuel control automation) make it possible not only to operate the engine on diesel fuel or natural gas but to automatically change over from one type of fuel to another with no change in steady-state conditions of the GTE. This option is accessible in any engine operating mode. The use of duel fuel allows the E70/8RD application to be extended in marine infrastructure facilities which are expected to have both diesel fuel and natural gas or their interchange depending on facility conditions.

The unified gas generator of the GTE E70/8RD has been tested in service as part of drives of gas-compressor units (over 160 000 hours in service) and has a corrosion-resistant design.
