Onshore and offshore services

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; and Lot 2: WPB: On- and offshore geotechnical boreholes, refractions seismic survey and Electrical Resistivity Tomography (ERT). Lot 1: WPA: Offshore geophysical survey includes offshore geophysical survey covering Multibeam (MBES), Side scan sonar (SSS), Magnetometer (MAG), Subbottom profiler (SBP) and Single channel sparker seismics (SCS) at three crossings. The objective is to obtain knowledge of the seabed and subsurface for optimizing and safe positioning of geotechnical boreholes and further authority processing cf. Scope of Work (21/00167-29), section 2.3. 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.
