The gas-in procedure for the second string of the Nord Stream 2 pipeline started on December 17, the operator of the Nord Stream 2 project said in a statement on Friday.
"Like the first string, the second string will be gradually filled with gas to build the required inventory and pressure," the statement said.
Earlier, pre-commissioning activities on the second string were completed successfully to assure the pipeline integrity.
Nord Stream 2 will inform about further technical steps in due time, according to the statement.
"The pipeline is built and independently certified according to applicable technical and industry standards to ensure reliable and safe operations," the operator noted.
