What to do with a depleted gas field in the North Sea and its associated infrastructure? Porthos has the answer and Boskalis, together with partner Allseas, has worked hard this year to prepare one of those gas fields for a second life as an offshore CO2 storage facility.
In recent months, Boskalis has deployed the trailing suction hopper dredger Gateway and the backhoe dredger Manu-Pekka to prepare for the installation of the 22-kilometer-long offshore pipeline by Allseas. As part of this work, Boskalis dredged a trench through the busy Maasgeul shipping channel. Not to be forgotten are the crucial air diving operations carried out by Boskalis’ Inshore & Nearshore Diving Services team. Divers worked at a depth of 17 meters in the fast-flowing Maasmond fairway, performing a variety of tasks for the subsea pipeline pull-in preparations.
In recent months, our divers have also been active offshore, as part of the same project, carrying out various diving operations on the foundation of the P18-A platform. From a custom-built diving platform on board Allseas’ pipe-laying vessel Lorelay, the divers entered the water to install clamps for the installation of the 16-inch riser. Two long spool pieces were then fitted to the riser.
We thank our divers for their dedicated and safe work, and our clients for the excellent collaboration throughout the project.
