Nord Stream AG has announced that a full external inspection of the Nord Stream gas export pipelines has been carried out and notes that the pipelines are in a period of settlement and that all changes are consonant with the design parameters.

The work was executed using a Remotely Operated Vehicle (ROV), equipped with digital cameras, specific sensors and operated from a dedicated support vessel. The visual and instrumental (geophysical) inspection was performed on the whole length of the dual 1,222 km pipeline through the Baltic Sea.

The goal of the inspection survey was to collect high-quality data to assess the integrity of the two pipelines through the analysis of several factors: accurate position of the pipelines (vertical and horizontal), depth of burial into the seabed, possible free-spans, condition of the cathodic protection system, verification of existing cables and pipelines crossings, status of intervention works (settlement berms).
