Russia is currently in the final stages of the development of a new 8 MW gas turbine power generation unit that is based on the indigenous E70/8RD dual-fuel gas turbine engine. This achievement represents another important milestone in the country’s efforts to replace the imported industrial energy equipment. The new power unit is primarily intended for offshore oil and gas platforms, large commercial vessels, and coastal energy infrastructure. It boasts an operational flexibility that is uncommon in its category: the capacity to automatically transition between natural gas and liquid fuel without disrupting power generation or reducing output.
The initiative is being overseen by UEC Engineering, a subsidiary of the United Engine Corporation (UEC), which is a division of the Rostec State Corporation. The marine energy unit is close to completion, and the company expects that the first deliveries will happen within the next year following the completion of final testing and certification.
Based on the indigenous E70/8RD engine
At the heart of the new energy system is the E70/8RD, a two-shaft marine gas turbine engine developed by UEC-Saturn in Rybinsk. The engine is derived from the M70FRU naval propulsion engine, but it has been extensively redesigned for industrial power generation rather than direct propulsion.
In contrast to conventional gas turbines, which typically operate on a single fuel source, the E70/8RD is equipped with a dual-fuel combustion chamber that has been specifically designed to operate on either gaseous or liquid fuels. It can burn natural gas, including associated petroleum gas produced during offshore oil extraction, while also operating on diesel fuel or kerosene whenever gas supplies become unavailable.
The engine’s completely automatic fuel transition system is its unique feature. This eliminates the necessity for shutdowns or reductions in electrical output by allowing operators to switch between gas and liquid fuel while the engine is under load. This capability significantly improves operational reliability for remote offshore facilities, where fuel logistics are frequently challenging and power generation interruptions can be costly.
Designed Specifically for Harsh Marine Environments
The new 8 MW gas turbine generator is designed for marine applications that necessitate equipment that can endure high humidity, salt-laden air, severe temperature fluctuations, and continuous operation for extended periods.
The unit is capable of supplying both thermal and electrical energy as a standalone generating station or in parallel with larger power infrastructures, as per UEC. This adaptability renders it appropriate for a variety of applications, including floating production units, large cargo ships, tankers, floating gas turbine power stations, and coastal industrial facilities that support offshore energy projects.
The E70/8RD is unique among Russia’s industrial gas turbine portfolio in that it is the only domestically developed dual-fuel marine gas turbine engine that is capable of seamless autonomous fuel switching under load, according to Russian engineers.
Years of Development Moving Toward Certification
In late 2023, UEC publicly disclosed its efforts to develop a new offshore energy system at the St. Petersburg International Gas Forum.
The Russian Maritime Register of Shipping initiated a survey of both the prototype and the first serial-production E70/8RD engines in late 2025. The engine’s design documentation, manufacturing procedures, and major components are all approved during the certification process to guarantee that they meet the rigorous marine safety and reliability standards.
The Register has already approved several critical compressor components and is currently assessing the quality of production before granting full certification for marine use. Commercial deliveries are expected to commence in 2026, following the completion of the overall energy unit.
Expanding on the GTA-8’s Success
The new dual-fuel energy system is directly derived from the knowledge acquired through the operation of UEC’s previous GTA-8 gas turbine generating unit.
That earlier 8 MW power system has already entered operational service. Four GTA-8 units were delivered to Gazprom’s Kamennomysskoye-Sea ice-resistant floating production platform in the Arctic, which supplies electricity for one of Russia’s strategically significant offshore gas developments.
Supporting Russia’s Offshore Import Substitution Strategy
The project is a component of a much larger industrial initiative to localize critical equipment that was previously sourced from international manufacturers.
For an extended period, Russia depended primarily on imported gas turbine equipment for offshore energy production, particularly in the 8 MW to 20 MW power sector.
Russian energy companies may require more than 100 marine gas turbine units by 2040, with the majority falling within the 8 MW and 16–20 MW power categories, according to UEC. Rostec and Russia’s energy sector have both prioritized the domestic fulfillment of this demand.
Expansion Plans Already Underway
The E70/8RD engine is only the beginning of a broader family of industrial gas turbine products.
Concurrently, UEC Engineering is in the process of developing an 8 MW gas compressor unit that uses the same engine platform. This enables the key technology to be used for both power generation and natural gas transportation infrastructure.
In the future, engineers intend to create a 16 MW energy unit that is much larger and is based on the M90FR marine gas turbine engine. The larger system would expand the company’s portfolio into a market segment that was previously dominated by imported equipment, while also targeting higher-capacity offshore installations and significant industrial energy consumers.
The production of the larger 16 MW systems could start once there is sufficient customer demand, which would complement the new 8 MW platform and establish a comprehensive domestic family of marine industrial gas turbines, according to officials.
A Flexible Solution for Offshore Energy Security
As offshore oil and gas operations expand beyond the shoreline and into more challenging environments, the necessity of uninterrupted power generation for environmental protection, production, and safety becomes increasingly apparent.
It is particularly appealing to offshore operators due to the E70/8RD’s ability to operate on natural gas, associated petroleum gas, diesel, or kerosene without necessitating shutdowns, as fuel availability can fluctuate unexpectedly and continuous power is essential. This operational flexibility improves the overall energy security of remote installations and minimizes downtime.
The new dual-fuel power unit has the potential to become a key example of Russia’s expanding domestic gas turbine industry if the program conforms to its schedule. This demonstrates UEC’s aspiration to build a comprehensive family of indigenous marine energy solutions that can support Russia’s long-term Arctic and offshore energy development strategy while reducing reliance on foreign equipment when combined with future 16 MW variants and gas compressor units based on the same technology.
