The installation of the approximately 20-kilometer-long offshore pipeline for the Porthos CO2 transport and storage project has been completed. The pipeline will transport captured CO₂ from the Rotterdam port industry to storage reservoirs under the North Sea.
This spring, the start of the offshore pipeline was extended under the sea wall to land. This marked the start of the laying of the offshore pipeline towards the platform. It is a 20-kilometer route across the bottom of the North Sea, from the compressor station on the Maasvlakte to platform P18-a above the depleted gas fields. Here, the CO₂ will be stored permanently and safely, more than three kilometers below the seabed. The pipes were welded together on a ship and lowered to the seabed.

Once the pipeline had been completely laid, it was sunk in trenches along the entire route and then covered with a layer of sand for extra stability and protection.
