Of course, wind turbines turn alone. But keeping it running takes a team of engineers. c’t 3003 went to the North Sea with them.
For eight years, 80 wind turbines have been turning in the Meerwind wind farm, 24 kilometers north-east of Helgoland. The giants are affected by wind, sun and salt water. Every day, technicians take ships to the wind turbines and take care of the systems that have been approved for 20 years. From investigations with divers on the foundation, work on the so-called “TP”, the yellow center piece that connects the base that was rammed into the sea with the wind turbine structure, to the electrical system and the rotors – every standstill costs money. After a short briefing on the weather conditions and the work to be done, the “Seewind 1” will set sail from the port of Helgoland to the North Sea. The former Norway fjord ferry takes the technicians to the wind turbines and Johannes Börnsen accompanies them with the camera.
The OSS substation, known as “Dicker Malte”, is also located in the middle of the wind farm. This is where the cables from the wind turbines come together and the electricity is converted to avoid losses. These systems must also be checked and serviced regularly. The technicians are therefore on the road 12 hours per shift, 14 days at a time, and there is more than enough to do.
c’t 3003 is c’t’s YouTube channel. The videos on c’t 3003 are independent content and independent of the articles in c’t magazin. Editor Jan-Keno Janssen and video producers Johannes Börnsen and Şahin Erengil publish a video every week.
