Germany Invites Geotechnical Inspectors
Germany’s Federal Maritime and Hydrographic Agency (Das Bundesamt für Seeschifffahrt und Hydrographie (BSH)) has issued a call for the provision of geotechnical investigations in the North Sea and the Baltic Sea.
The tender is divided into two lots, the North Sea lot and the Baltic Sea lot.
The geotechnical exploration works include drilling, core sampling and investigation, pressure probing, borehole geophysics, laboratory investigations, as well as documentation in the context of a preliminary investigation in accordance with the German Offshore Wind Energy Act (WindSeeG).
Drilling and pressure probing will be carried out at up to 80 meters from the seabed surface, in water depths of up to 50 meters. Based on the results of the drill core approach, the laboratory programme, which includes the classification, soil and rock mechanical tests, must be specified by the contractor.
In the North Sea, the survey will be conducted in two areas between the traffic separation areas German Bight Western Approach and Terschelling German Bight.
In the Baltic Sea, the survey will be carried out in an area 38km northeast of the island of Rügen, adjacent to Wikinger and Arkona offshore wind farms.
The contracts are scheduled to start on 15 April and conclude on 15 November 2019. The tender will remain open for submissions until 1 April.
