Offshore site investigations

Offshore wind farm

The Federal Maritime and Hydrographic Agency (BSH) investigates the areas designated in the Site Development Plan for tendering procedure by the Federal Network Agency (BNetzA) and wind farm construction. The marine environment, subsoil, wind and oceanographic conditions as well as the traffic suitability of the area are investigated and compiled in reports. Based on the results of the investigation, the BSH examines the suitability of the area. If the BSH comes to the conclusion that the site is suitable, it declares its suitability by statutory order and the results of the investigation are transmitted to the BNetzA for the tendering procedure.

Most of the investigations are not carried out by the BSH itself, but are commissioned within the framework of public tenders. The results of the investigations and reports are published by the BNetzA for the tendering of areas designated for the construction and operation of offshore wind turbines. On this basis, interested companies can submit bids for the amount of compensation they need.

The investigation results also serve the company that was awarded the contract in the tender procedure as a basis for the subsequent planning approval procedure to be carried out at the BSH. On this basis, the applicant will prepare an environmental impact study for the construction project.
