Preliminary Investigation of Sites
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. Furthermore, the results are made available via the Data Hub of the Preliminary Investigation of Sites.
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.

07.10.2021: Feedback request regarding the Data Hub Preliminary Investigation of Sites until October 31th, 2021
The BSH investigates the areas in the German EEZ designated in the Site Development plan for tendering procedure by the BNetzA and wind farm construction.
On February 26th, 2021, with the publication of the results for download for the areas N-3.7, N-3.8 and O-1.3, the data, evaluations and reports of the preliminary investigation were made available for the first time via the BSH's Data Hub Preliminary Investigation of Sites.

In order to further enhance the user-friendliness of the Data Hub Preliminary Investigation of Sites for the upcoming tendering procedures, the BSH is interested in your experiences and kindly requests your feedback by October 31th, 2021 using this questionnaire.
The questionnaire, which is available in German and English, is designed in topic blocks and covers the use of the data hub in general, the provided data from the subsoil with geophysics, hydrography, geotechnic and geodata, the marine environment data as well as oceanography and wind, suitability and environmental assessment. Since it is possible to skip individual topic blocks, it is not necessary to answer all questions. You will need 15 to 20 minutes to answer. The BSH is grateful for your support!
