D12-B

Location and Geography

• The D12-B field is located in the North Sea, off the coast of the Netherlands.

Operator

• The field is operated by Wintershall Noordzee B.V..

Pipeline and Infrastructure

• The project involves a pipeline route from offshore block D12 to D15. This route includes a proposed pipeline trajectory with a 1000m buffer zone on both sides, creating a 2000m corridor. The actual pipeline route can be shifted within a 700m corridor to avoid obstacles.
• The pipeline crosses an area with existing pipelines and cables. For example, pipelines operated by Noordgastransport B.V. and ENGIE E&P Nederland B.V. are present in the research area.

Depth and Seabed Conditions

• The depth along the pipeline route varies from -28.1 meters LAT (Lowest Astronomical Tide) in the northwest to -43.7 meters LAT in the southwest. The seabed is described as smooth, with no large-scale sand waves present.

Archaeological and Environmental Considerations

• An archaeological desk study and assessment of geophysical survey data were conducted to evaluate the impact of the pipeline on historical sites. The study area includes a 1000m buffer zone on both sides of the optional pipeline routes.

Production Status

• The D12-B field is a producing field, indicating that it is currently in operation.

Additional Context

• The project involves detailed planning and execution, including trenching and the use of subbottom profilers to create seismic profiles of the subsurface. This is part of the broader environmental and archaeological assessments necessary for offshore projects.
