Mitsubishi Heavy wins order for Ust-Luga LNG

Linde Engineering has awarded Mitsubishi Heavy Industries (MHI) contract to supply the main refrigeration gas compression trains for the Ust-Luga LNG project in Russia.

The order specifically consists of the dual shaft 120 megawatt H-100 gas turbines and centrifugal compressors.

The Ust-Luga LNG project is a natural gas liquefaction plant that will apply the liquefaction tech by Linde and Gazprom. It will have two trains that will produce upwards of 13 million tons per annum (mtpa). RusChemAlliance, the 50-50 special-purpose venture of Gazprom and RusGazDobycha, leads the project.

The plant will be near the Baltic seaport of Ust-Luga in Leningrad region. It will use natural gas gathered from domestic sources via Russia’s Unified Gas Supply System (UGSS).

The EPC contract for the project wrapped up in September 2021. In addition, the parties involved hope for the start of LNG production by 2026.

MHI CEO Seiji Izumisawa said, “This project will showcase the benefits of MHI’s LNG solution in terms of lower production costs, increased productivity, reduced complexity, and lower lifecycle costs, while significantly reducing plant emissions.”

MHI says it has an extensive record of delivering turbomachinery to the oil and gas industries. It also continues to be a major turbomachinery player in the Russian market.

The company says its H-100 is ideally suited to drive the main refrigeration compressors in large scale LNG plants for these reasons:

• Higher efficiency in its Heavy-Duty class, which reduces CO₂ emissions, compared with the conventional types of Heavy-Duty gas turbine;
• The dual shaft design does not require a large external starter / helper motor, thus contributing to a more compact footprint and space savings;
• Operational flexibility, thereby eliminating the need to flare refrigerant;
• Using Mitsubishi’s combustor technology, the H-100 is advanced in low nitrogen oxide emissions in full-load operation

These features contribute to maximizing overall plant efficiency and LNG production while providing significant reductions in emissions.

In conclusion, MHI says it will continue to integrate and expand its technology portfolio to meet the world’s needs for energy and reduced GHG emissions.
