EHS Site Manager Onshore Converter Station DolWin3
Dennis Veenhoven works as an EHS Site Manager at the Onshore Converter Station DolWin3 in Germany. His activities include the daily preparation of permits and participation in the coordination meeting and conducting safety walks to monitor the EHS performance of all people working on the site. In this article, he tells us about the project and his job.
Windmill generated power
“The national high voltage grid in Germany has been extended to enable transportation of the power generated offshore by the large number of windmills. To ensure the energy losses are limited, the alternated current (AC) is offshore converted into direct current (DC) and transported through 2,160 km long subsea cables to the onshore transformer station Dörpen West. In the transformer station, the generated electrical power is converted into AC to enable connection to the existing German high voltage (380kV) grid.”
About the job
“Since September 2015, I’ve been working as EHS Site Manager at the onshore converter station, consisting of two valve buildings, one reactor building, switch yard, cooling building and cooler, two transformers and a control building. My activities include the daily preparation of permits and participation in the coordination meeting and conducting safety walks to monitor the EHS performance of all people working on our site.”
“Everyone entering the site receives safety instructions. People working on site come from various countries: Germany, France, Poland, The Netherlands, Croatia, Serbia, Tunisia and the UK. Most people speak either German or English. People that don’t speak either of these languages will be supported with a translator during the safety instruction, resulting in several safety instructions taking place in one day.”
Current phase of the project
“In the current phase of the project we transform from construction and erection to commissioning. Step by step all installations will be energized. Lock-out and tag-out will be performed to ensure people can work safely on the installation. Lock-out and tag-out is the process where the installation is switched off and locked to prevent re-energization. People receive a personal photo-ID tag indicating security level.”
Start of project
“The project started when Alstom was the main contractor. Last year, Alstom was taken over by General Electric (GE). The extensive ‘Alstom Zero Deviation Program’ has been implemented on site. In addition to the Alstom requirements, we also implement GE company requirements and the German nationwide requirements.
It is a pleasure to work and to contribute to a project that enables Germany to increase the use of renewable energy sources.”
