Summary
I have worked more than 25 years for Siemens Energy, mostly as an HSE Manager in a central function. I reported to the Board of Management on all HSE topics. I supported senior management and staff at manufacturing locations, in projects, and on construction sites of power plants in the oil & gas industry and wind farms, offshore and onshore, worldwide.
As the lead QEHS Auditor, I supported Siemens site certifications and carried out internal audits with my team. As part of the audits, we also checked risks and weak points in property protection at sites and construction areas, covering "influences from within" and "influences from outside" through a layered security concept.
My freelance work builds on my many years of experience and knowledge as an HSE manager in power plants, refineries, the chemical industry, and the automotive industry.
