Aflandshage Offshore Windfarm, Denmark

The Aflandshage Offshore Wind Farm is a 286MW offshore wind power project situated in the Baltic Sea, south of Copenhagen. The windfarm project plans 26 turbines spread over an area of 44km² each with 11MW nameplate capacity.

The project should generate enough electricity to power up to 300,000 homes around the Øresund region and will be a major contribution to Denmark’s goal to reduce CO2 emissions by 70% by 2030.

Robertson Geo were contracted to Danish company GEO Subsurface Expertise to conduct wireline logging on the Sound Prospector jack-up vessel as part of the geotechnical survey. Mobilising from Malmo in Sweden, five 35m boreholes were logged over a two-week period. The geology encountered was mainly chalk/limestone.

The Robertson Geo probes selected for this geotechnical survey were chosen to provide structural information (High Resolution Optical Televiewer® and High Resolution Acoustic Televiewer®) and to enable stiffness parameters to be calculated (PS Logger® and Formation Density). The resulting data was processed in situ by the logging engineer and then QC checked at the Robertson Geo head office.
