The offshore wind power plants are electrically connected to the accommodation and transformer platform.
On “BARD 1” the alternating current from a total of 80 wind turbines is converted from 33kV to 155 kV and then transferred to the neighbouring converter platform “BorWin 1”.
“BARD 1” was installed in the North Sea in the summer of 2010. It is a floating and self-installing platform. Several tugboats were needed to tow the platform to the project area where it was positioned. The “substructure,” as the foundation is called, was then lowered to the seabed, whereby the topside of the construction lifted itself out of the water automatically. The “topside” – the actual platform with the accommodation unit and the two transformers – was completed at the Western Shipyard in Klaipeda, Lithuania. The installation of the foundation structure and the hydraulic components took place at the Harland & Wolf shipyard in Belfast, Northern Ireland. Currently, a commissioning team is stationed on the platform. Later on the platform will accommodate service technicians working around the clock at the offshore wind farm “BARD Offshore 1”.
