The leading global quality assurance and risk management company DNV GL has extended the certificate of conformity to the offshore standard for underwater pipelines DNV-OS-F101 for the Nord Stream gas pipeline for the seventh time.

The annual renewal of DNV GL’s certificate during operations by Nord Stream AG has proven year after year the continuously high level of safety and reliability of this gas pipeline.

The Nord Stream Pipeline was designed and built in compliance with DNV GL’s international certification standard DNV-OS-F101. During the commissioning of Line 2 in October 2012, DNV GL issued the first certificate confirming the compliance of the Nord Stream Pipeline with the requirements of said standard. Over the following years, Nord Stream AG engineers and DNV GL experts have been working closely together to develop the Pipeline Integrity Management System (PIMS), as well as to verify and monitor its operation and maintenance procedures. The companies exchange technical and process information and regular reports on an ongoing basis, which allows them to ensure high annual performance, as well as a positive assessment by DNV GL of how during the operation, Nord Stream AG ensures proper compliance with all required conditions for safe and reliable gas transportation.

Marcus Korthals, Compliance Director at Nord Stream AG, commented on the long-term cooperation between the two companies: “Since 2012, DNV GL has been providing us with the highest quality expertise in construction and operation of offshore pipelines. We are pleased that this well-known international company recognises the integrity of our system, which guarantees reliable and safe transportation of natural gas from Russia to Europe.”

Nils Andreas Masvie, Vice President Eurasia at DNV GL Oil & Gas, says: “We are once again pleased to confirm the highest level of safety and reliability of the Nord Stream gas pipeline. Since the pipeline’s commissioning in 2012, Nord Stream AG has shown that both lines of the pipeline meet the most stringent requirements of the offshore standard regulations for subsea pipelines every year.”

Nord Stream’s natural gas pipelines run in parallel through the Baltic Sea for 1,224 kilometres from Portovaya Bay, near Vyborg on the Russian Baltic Sea coast to Lubmin, Germany. Each pipeline comprises some 100,000 24-tonne concrete-weight-coated steel pipes laid on the seabed along the precise route approved by the authorities of the five countries through whose waters the pipelines pass.
Nord Stream is committed to safety and the environment: During the project planning, the joint venture invested 100 million euros in the most comprehensive research of the Baltic Sea ever conducted. Another 40 million euros were invested during the recovery period thereafter in order to guarantee that the environment is not adversely affected.
