Work Detail

Test Drilling And Boring Work - Conclusion Of A Framework Agreement For Preliminary Area Investigation And Exploration In The German Eez Of The North Sea From 2027 Including Laboratory Tests And Documentation (Ferkl 2026). Geotechnical Exploration In The German Eez Of The North Sea Including Documentation As Part Of The Preliminary Investigation In Accordance With Section 10 Paragraph 1 No. 2 Windseeg. Geotechnical Exploration Includes Continuous Pressure Sounding, Discontinuous Pressure Sounding, Borehole Geophysical Measurements, Drilling For Sampling Including Soil Exploration, As Well As Laboratory Investigations. The Areas To Be Examined Per Year Are Specified In The Area Development Plan (Fep). The Aim Is To Start With Continuous Pressure Sounding In The Respective Examination Room. The Depth Of Continuous Pressure Sounding Should Be Carried Out Until The Process Limit Is Reached. The Target Depth (Max. 80 M Below The Lake Bed) Of The Exploration Is Then Reached By Carrying Out Discontinuous Pressure Sounding. Before Drilling For Sampling Can Begin, All Pressure Sounding Results Must Be Collected. It Is Important To Carry Out The Explorations In A Logistically Optimized Manner For Each Fep Area. The Client Reserves The Right To Determine The Sequence Of The Exploration Work. The Depth Of The Indirect And Direct Outcrops Is A Maximum Of 80 M Below The Lake Floor. The Depths To Be Explored At The Individual Pressure Sounding Locations Are Determined In Advance By The Separately Commissioned Geotechnical Support Team. After The Pressure Sounding Results Have Been Fully Collected, They Are Evaluated By Geotechnical Support So That The Number And Depth Of Drilling Holes For Sampling Can Be Determined. Non-Cohesive Soils Will Probably Only Be Sampled In Sections And Cohesive Soils Will Probably Be Sampled Continuously. Sampling Drilling Is Carried Out At Selected Pressure Sounding Locations. Based On The Results Of The Drill Core Approach, The Specified Laboratory Program, Which Includes The Classification And Soil Mechanics Tests, Is To Be Determined By The Geotechnical Support And Carried Out By The Contractor For This Tender. The Field Investigations And Documentation Must Be Carried Out In Accordance With Din En Iso 19901-8:2024-01. The Laboratory Tests Should Be Carried Out In Accordance With Current Standards And The Bsh Standard For Subsoil Investigation For Offshore Wind Energy Parks. The Results Of The Field Investigations Must Be Summarized In An Investigation Report. The Laboratory Results Must Be Documented In A Laboratory Data Report. For The Year 2027, Pressure Soundings Will Be Carried Out At 25 Locations (13 Locations Up To 80 M And 12 Locations Up To 60 M) And Drilling For Sampling Up To A Depth Of 80 M Will Be Carried Out At 13 Locations. For The Year 2028, Pressure Soundings Will Be Carried Out At 25 Locations (13 Locations Up To 80 M And 12 Locations Up To 60 M) And Drilling For Sampling Will Be Carried Out At 13 Locations (3 Locations Up To 80 M And 10 Locations Up To 60 M). The Exploration Locations For 2027 Will Be Different
