BARD Offshore Projects
BARD Engineering GmbH
BARD-Group:
The Structure / Organisation for Turn key supply
The aim of the BARD Building is the smooth installation of the offshore wind farms.
A professional team is coordinating the erection of the foundation system, tower segments, nacelle,
hub and blades. After the grid connection the wind turbines are handed over to BARD Service company
who is responsible for operation and service of the offshore wind farms.
