"I welcome the fact that construction of the Nord Stream 2 gas pipeline continues. This shows that most of the companies involved are not intimidated by the United States. Nevertheless, some of the threats of US sanctions are working, as can be seen from the recall of the DNV GL certification body," Ernst said in a statement.
On Saturday, the operator said that pipe-laying work will resume this year and an anchored vessel will be used.
The Norwegian-German certification firm DNV GL pulled out of the project in late November. The lawmaker said that the European Union needs effective tools to defend against US interference in the bloc’s energy policy.
Nord Stream 2 is a planned 745-mile-long twin pipeline that will carry nearly 2 trillion cubic feet of gas annually from Russia to Germany. The US opposes the project and has been seeking to export more liquefied natural gas to Europe.
Moscow has described Washington's actions, including the threat of sanctions, as a desire for unfair competition.
