Beschreibung

Lot 1 covers the geophysical surveys needed for the project. The survey area is located in the German sector of the North Sea. For Section I the route corridor is estimated to be 117.8 km in length with water depths varying between 15 and 41 metres. For Section II (optional) the route corridor is estimated to be 200 km in length with water depths varying between 30 and 45 meters. Further details regarding service provision - that are not relevant for cost calculation - will be provided after the contract is awarded. Wider localised survey coverage may be required in areas where the seabed topography or geology is less suitable for pipeline installation or nearby infrastructure positions need to be confirmed. This will be decided as the survey progresses. It is anticipated that line spacing for the geophysical survey will be based on a centre line and then 3 lines each side at approximately 75m spacing. The survey parameters (line spacing, equipment settings etc.) will depend on the proposed method of acquisition - vessel, ROV based or other towed system. The aim is to confirm the feasibility of a surveyed route or area during the survey. Further technical specifications are detailed in "B.1.1 Scope of Work Package A (Lot 1)". — Lot 2 covers the geotechnical surveys needed for the project. The survey area is the same as in Lot 1 (German sector of the North Sea; Section I: the 7-A16 route corridor length along which the geotechnical investigation is to be conducted is approximately 117.8 km in length. Water depths vary from 41 to 15 meters. For Section II (optional) the route corridor is estimated to be 200 km in length with water depths varying between 30 and 45 meters. Further details regarding service provision - that are not relevant for cost calculation - will be provided after the contract is awarded. The geotechnical acquisition will consist of piezocone penetration tests, electrical resistivity cone testing and piston and/or vibro cores to describe the geotechnical properties of the seafloor soils. The geotechnical sample locations will be selected on the basis of the results coming out of the geophysical studies (Lot 1). Further technical specifications are detailed in "B.1.2 Scope of Work Package B (Lot 2)". — Lot 3 covers the geophysical and geotechnical surveys needed for the project section in shallow waters. The survey area is located in the German sector of the North Sea. The survey corridor has a total length of approximately 7 km in water depths varying from 15 meters to shore (top of beach line). At low tide the beach is expected to dry out forming mud flats for a distance of ~200m. Further technical specifications are detailed in "B.1.3 Scope of Work Package C (Lot 3)". — Lot 4 covers the geotechnical surveys needed for the tunnel section of AquaDuctus pipeline. The survey area includes two dry sections, the foreland areas and the intertidal mud flats. The survey corridor has a total length of approximately 7 km. Further technical specifications are detailed in "B.1.4 Scope of Work Package D (Lot 4)".
