Offshore construction specialist Allseas has been selected for the subsea pipeline project of the Porthos carbon capture and storage (CCS) project in the Port of Rotterdam, the first development of its kind in the Netherlands.

Porthos, 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.
