Moscow Modernizes Underwater Gas Pipelines Using Digital Technologies
All reconstructed underwater crossings have been connected to a central dispatch control system.
One of the most technically complex infrastructure programs in recent years has been completed in Moscow. The Russian capital has modernized 12 underwater gas pipelines laid beneath the bed of the Moskva River and other bodies of water. The project combined advanced trenchless construction techniques with elements of digital transformation.
The reconstruction covered high- and medium-pressure trunk gas pipelines with a total length of about nine kilometers. Originally built between 1939 and 1965, the lines were upgraded using microtunneling instead of traditional construction methods. This trenchless approach uses specialized jacking stations to install pipelines and utilities, allowing new pipes to be laid at depths of up to 20 meters without disturbing river ecosystems. Each pipeline is now equipped with triple-layer protective insulation and automated shutoff valves.
Remote Monitoring
All reconstructed underwater pipelines have been connected to the central dispatch system operated by Mosgaz. This allows operators to monitor network conditions remotely and, if necessary, shut off gas supply to any section of the system in as little as 90 seconds.
The city has previously reported that researchers from Perm National Research Polytechnic University have developed a technology for designing pipelines suitable for hydrogen transport.
