Installation of the pipeline under the Kedzierzyn Canal was completed in 8 hrs, and it took 42 days to drill the hole up to a diameter of 1320 mm. The section of the gas pipeline (lyre) prepared to be pulled in passed above an active process pipeline, which meant that it was necessary to protect this pipeline by lifting the lyre on a dedicated structure. “This was the second and last HDD drilling related to the construction of the Tworóg–Kedzierzyn-Kozle gas pipeline. The first one, which was 750 m long, passed under the Gliwice Canal, Klodnica River and the Bojszówka River,” said Artur Zawartko, Vice-President of GAZ-SYSTEM.
