For the wind farm area a total of 4 out of 15 planned boreholes were executed. The boreholes were planned to penetrate to approximately 40m below seabed, however only one borehole was carried out to the planned depth. At each borehole soil samples were taken using a down-hole push/piston sampler, along with penetration tests using a piezo-cone penetrometer tool. Detailed soil/rock descriptions of all samples from the boreholes were made offshore and classification and strength tests were executed on selected samples. This series contains numerous reports, including the Field Report, which summarizes the field and offshore laboratory work for the borehole campaign, and contains detailed soil/rock descriptions and logs.

The following shall be noted in relation to the performed tests:  From BH-12 tests on specimen No.15.1D (14.5 meters below seabed (m.b.s.)) were cancelled due to insufficient material. The tests were carried out on a sample from 12.3 m.b.s. This sample has no specimen number.  From BH-15A specimen No. 4.1D was unsuitable for testing.  From BH-15A the CIU test on specimen No.13.2U was cancelled and replaced by No. 20.1U.  Sample 9.1U and 14.1U from BH-15A are described as SAND on both Particle Size Distribution sheets, Appendix 2.VI, and UU-test sheets, Appendix 2.II, but as CLAY in the borehole log, Enclosure 2D.04.According to the results of the Particle Size Distribution the content of particles smaller than 63 μm is above 35 % and both samples may be described as low plastic CLAY.  Sample 12.1U from BH-15A is described as SAND on both the Particle Size Distribution sheet, Appendix 2.VI, and on the UU-test sheet, Appendix 2.II, but as SILT in the borehole log, Enclosure 2D.04. According to the result of the Particle Size Distribution the content of particles smaller than 63 μm is above 35 % and the sample may be described as low plastic CLAY.
