Investigations for marine crossings – Green Gas Lolland-Falster (GGLF)

Description

The Green Gas Lolland-Falster (GGLF) project will facilitate transport of gas from Zealand to the sugar factories in Lolland and Falster. For this a new gas pipeline is planned. In connection to this gas pipeline there will be three marine crossings in which Horizontal directional drilling (HDD) needs to be carried out. The assignment is divided into 2 lots: LOT 1 – WPA: Offshore geophysical survey LOT 2 - WPB - On- and offshore geotechnical boreholes, refractions seismic survey and Electrical Resistivity Tomography (ERT) Lot 1: LOT 1 – WPA: Offshore geophysical survey LOT 1 - WPA - Offshore geophysical survey includes offshore geophysical survey covering Multibeam (MBES), Side scan sonar (SSS), Magnetometer (MAG) at three crossings. The objective is to obtain knowledge of the seabed for optimizing and safe positioning of geotechnical boreholes and further authority processing cf. Scope of Work (21/00167-29), section 2.3. Please note that this is a negotiated procedure. With the exception of mandatory parts, the Tender Documents may as a result undergo changes as part of the negotiation process. Lot 2: LOT 2 - WPB - On- and offshore geotechnical boreholes, refractions seismic survey and Electrical Resistivity Tomography (ERT) LOT 2 – WPB - On- and offshore geotechnical boreholes, refractions seismic survey and Electrical Resistivity Tomography (ERT) includes on- and offshore geotechnical bore-holes, refractions seismic survey along center line both on- and offshore and Electrical Resistivity Tomography (ERT) onshore along center line cf. Scope of Work (21/00167-29), section 2.3. Please note that this is a negotiated procedure. With the exception of mandatory parts, the Tender Documents may as a result undergo changes as part of the negotiation process.
