On its company website, Herrenknecht lists that it has three offices in Tehran, Iran. (Company Website)

"Germany’s multi-billion euro bilateral trade relationship with Iran continues unabated, even as evidence mounts that the Islamic Republic is determined to build a nuclear weapons capability. The Jerusalem Post has obtained an uncensored list from late 2011, showing hundreds of German and Iranian enterprises in a flourishing trade relationship . . . One company named is Baden-Württemberg-based engineering giant Herrenknecht AG, which appears to be delivering heavy tunneling equipment to Iran – some of which is promoted as having the capability of 'drilling down to depths of 6,000 meters.' In response to Post inquiries, an unidentified representative of the company wrote via email on Friday that it has 'comprehensively ensured that Herrenknecht excavation engineering and services solely reach projects which clearly pursue civil applications [metro tunnel construction, sewage pipes and water supply lines]' . . . Though EU sanctions have been in place since 2010 to bar oil and gas technology trade with the Islamic Republic, Herrenknecht participated in Iran’s most important oil trade show in 2012. To participate in the Iran oil show, companies are required to send their registration fees to Bank Mellat – which the EU and US had sanctioned due to its involvement in nuclear proliferation."

Such tunneling conferences, held regularly in Tehran, draw global manufacturers of tunnel-boring machines — giant devices as big as locomotives that dig quickly through rocky strata...

Many of the companies keep offices in Tehran. Herrenknecht, a German firm considered the market leader, lists three. Engineers say Iran has hundreds of miles of civilian tunneling projects under way, including subways in Tehran, Isfahan, and Shiraz, highway tunnels across the country and water tunnels to irrigate the dry interior.
