The story
In 1970 Deutsche Babcock bought the company Borsig AG; therefore, years later the company name changed to Babcock Borsig AG.
Since 2005, the Babcock Borsig Service Group is a subsidiary company of Bilfinger Berger AG.
Before the integration some branches were established abroad, just like Deutsche Babcock Middle East and also some joint-ventures, as Deutsche Babcock Al Jaber.
After this integration, the BBS GmbH – as all its subsidiaries, branches and joint-ventures – operates since May 2006 under the umbrella of the Bilfinger Berger Power Services (BBPS GmbH).
In addition to the GmbH is a number of subsidiaries belonging to the Group. The main companies are Steinmüller, Babcock Noell and Babcock Borsig Power Holding.
