Boskalis’ trailing suction hopper dredger Gateway has completed a project off the Dutch coast for the Porthos CO2 transport and storage project, according to the company's release.
The vessel, contracted by Allseas, dredged a pipeline trench from the Maasmond, the main entrance to the Port of Rotterdam, to the P18-A platform in the North Sea.
The offshore pipeline and platform are components of a project designed to store CO2 from companies in the Rotterdam port area in depleted gas fields.
After pipeline installation, Gateway returned to the site to cover the pipeline with a layer of sand to protect it from North Sea forces.
Additionally, a team of air divers from Boskalis’ Inshore & Nearshore Diving Services unit worked on the project.
Operating from the backhoe dredger Manu-Pekka, which served as their diving platform, the divers descended to a depth of approximately 17 meters to perform tasks on the installed pipeline.
In a later phase, Boskalis divers will return to the P18-A platform to install components and connect them to the subsea infrastructure.
