Porthos CO2 Pipeline Installed Offshore
- The offshore pipeline spans 20 kilometers from Maasvlakte to platform P18-a.
- CO2 is stored over 3 kilometers below the seabed in depleted gas fields.
- The pipeline was welded on a ship and laid on the seabed.
- It was entrenched and covered with sand for stability and protection.
Project Overview
The Porthos CO2 transport and storage project has completed the installation of a 20-kilometer offshore pipeline. This pipeline is designed to transport captured CO2 from Rotterdam's port industry to storage reservoirs located under the North Sea.
Pipeline Installation
The installation began with extending the pipeline under the sea wall to land, marking the start of the offshore segment. The pipeline runs from the compressor station on the Maasvlakte to platform P18-a, situated above depleted gas fields. The CO2 will be stored more than three kilometers below the seabed, ensuring permanent and safe storage.
Construction Process
The pipeline was constructed by welding sections together on a ship, which then lowered the completed pipeline to the seabed. Once laid, the pipeline was entrenched along its entire route and covered with a layer of sand. This additional layer provides stability and protection against environmental factors.
