Allseas to build subsea pipeline for Porthos CCS project

Allseas, an offshore engineering and construction company, has been selected to construct the subsea pipeline for the Porthos carbon capture and storage (CCS) project in the Port of Rotterdam, it said on October 23.

The Porthos project, a partnership between EBN, Gasunie, and the Port of Rotterdam Authority, will transport CO2 from industrial sites in the port area to empty gas fields in the Dutch North Sea, where it will be permanently stored up to 4 km beneath the seabed.

Allseas will install the 16-inch CCS pipeline connecting a compressor station on the Maasvlakte with the P18-A platform approximately 20 km offshore. The work is scheduled to start in 2025 and will be executed by Allseas' S-lay vessel Lorelay, with construction support from Oceanic.

The Porthos CCS project is expected to be operational by 2026 and is expected to reduce the Netherlands' annual CO2 emissions by about 2%. The pipeline will transport about 2.5mn tonnes/year of CO2 for 15 years to the North Sea storage site.
