The American sanctions and the Swiss contractor

Read the PDF edition (2 pages)

The United States adopted sanctions against the project in December 2019 through the Protecting Europe's Energy Security Act. Because the Act targeted the vessels that laid the pipeline on the seabed, the Swiss company Allseas, which operated the pipe-laying ships, stopped its work immediately. Construction was interrupted when only a short section of the route remained to be laid.1 Allseas, although headquartered in Switzerland, had its main operations in the Netherlands. Its withdrawal showed the reach of American sanctions over companies that depended on access to the dollar and to American business, foreshadowing the problems that Swiss companies would face after 2022.

Gazprom completed the pipeline with its own vessels and finished the work in September 2021. The American administration had waived sanctions against Nord Stream 2 AG itself in May 2021 in an effort to improve relations with Germany.2 The pipeline still needed certification by the German regulator before it could operate. The regulator required Nord Stream 2 AG to establish a subsidiary under German law to operate the German section, in accordance with the rules of the European gas market. It suspended the certification procedure in November 2021.3
