en.Wedoany.com Reported - On April 23, 2026, as the dome of the eighth storage tank was smoothly raised to the designed height and secured, the product tank farm of the Russian Arctic Methanol Project, undertaken by the Central Plains Branch of the 11th Chemical Construction Co., Ltd. of China National Chemical Engineering Group Corporation, completed the roof-hoisting operations for all eight 30,000-cubic-meter storage tanks.

The project faced challenges including severe winter construction conditions and delays in material supply. The team adopted an upright assembly method and a phased, batch-flow construction approach, ensuring efficient coordination between foundation and tank body installation. By employing a synchronized hoisting technique with a cluster of 36 ten-ton chain blocks, precise lifting accuracy was achieved, enabling continuous operations under harsh conditions.

Key milestones included: May 30, 2025—laying of the base plate for the first tank; June 24—installation of the first side plate; November 22—completion of welding for all side plates; December 17—hoisting of the first dome; and ultimately, on April 23, 2026, final positioning of the last dome. With all tank roofs now in place, subsequent work will proceed with roof plate welding, anti-corrosion coating, and thermal insulation tasks.
