Arctic LNG-2 is a project related to the production of liquefied natural gas. The project's resource base is the Utrennee field, discovered in 1979 and located on the Gydan Peninsula in the Yamalo-Nenets Autonomous Okrug, approximately 70 km from the Yamal LNG project on the eastern shore of the Ob Bay.
The project involves the construction of three technological lines for the production of liquefied natural gas, each with a capacity of 6.6 million tons per year. The total capacity of the three lines will be 19.8 million tons of LNG and up to 1.6 million tons of stable gas condensate per year. The project is based on an innovative construction concept using gravity-based structures (GBS).
The application of the technological construction concept using gravity-based structures (GBS), as well as extensive localization of equipment and material production in Russia, will significantly reduce the capital costs per ton of LNG produced within this project. This will ensure a low production cost and maximum competitiveness in all LNG markets.
The three technological lines will jointly use onshore facilities, including the central control room, onshore pipeline racks, an electrical substation, a high-pressure flare, a glycol solution start-up boiler, an ice formation monitoring system, and more.
The gravity-based foundations (GBFs) are manufactured in two dry docks at the Large-Scale Marine Structures Construction Center (CSKMS), located in the Murmansk region. The completed technological lines will be towed to the Gyda Peninsula, where they will be installed on prepared marine foundations in the coastal area. After that, they will be connected to onshore facilities, gas turbines will be ignited, and final commissioning will be carried out before launch. The first technological line is planned to be launched in 2023.
The unique location of the Gyda Peninsula allows for the creation of a flexible and competitive logistics model, ensuring year-round LNG deliveries to LNG transshipment complexes in the Murmansk region and Kamchatka for further transportation of LNG to markets in Europe and the Asia-Pacific region. 80% of the LNG from the project will be directed to the LNG complex in Kamchatka, and 20% to the LNG complex in Murmansk.
LNG delivery will be carried out by special ARC7 ice-class tankers, with transportation eastward along the Northern Sea Route during the winter period escorted by nuclear icebreakers.
