Construction Work For Water Projects – Dredging Work To Maintain The Fairway Of The Lower Ems And Leda 2026-2028. The Construction Work To Be Carried Out Is Wet Dredging Work (Cargo Suction Dredger) To Maintain And Restore The Required Target Depths And Widths In The Fairway In The Tidal Area Of ​​The Lower Ems From Km 0.0 To 40.7 And The Leda From Km 22.8 To Km 24.85. The Total Performance Includes The Excavation, Transport And Relocation Of Approx. 3.5 Million M³ Of Soil Volume (Surface Measurement). A Proportion Of Approximately 3.0 Million M³ Is To Be Washed Onto Land-Based Deposit Areas. The Remaining Portion Of Approximately 0.6 Million M³ Of Soil Is To Be Dumped Onto The Deposit Areas In The Ems Estuary. The Majority Of The Dredging Masses In The Ems (Approx. 63%) Fall On The Ems-Km 0.0 - 11.0 Section. The Soil To Be Dredged In The Lower Ems And Leda Consists Of Approx. 90% Silt. The Remaining Portion Must Be Declared As Sandy Soil. The Consistency Of The Silt Is Predominantly Mushy To Soft. The Dredging Work Must Be Carried Out In So-Called Dredging Campaigns. The Dredging Campaigns Serve To Temporarily Adjust The Lower Ems (Required Depth) For The Transfer Of New Shipyard Buildings From Papenburg To Emden. Planned Transfer Dates Of The New Shipyard Buildings (Dredging Campaigns 1 To 3), By Which The Depths Must Be Established: S724: Transfer According To The Shipyards Information On March 21, 2027 S723: Transfer According To The Shipyards Information On September 18, 2027 S725: Transfer According To The Shipyards Information On February 13, 2028 A Dredging Campaign Is Permitted Must Be Started At The Earliest 15 Weeks Before A Ship Transfer.
