Earlier this week, the gas-in procedure for the first string of the Nord Stream 2 pipeline, which will transport natural gas over some 1,230 kilometres from the world’s largest gas reserves in Russia through the Baltic Sea, has started.
This string will be gradually filled to build the required inventory and pressure as a prerequisite for the later technical tests.
Previously, the first string of the pipeline underwent pre-commissioning activities to assure the pipeline integrity. This included the internal inspection by special devices (pipeline inspection gauges), as well as external visual and instrumental surveys of the pipeline. Nord Stream 2 will inform about further technical steps in due time.
Now, pre-commissioning steps for the second string are ongoing.
