Boskalis in the North Sea: Dredging for new CO2 offshore storage facility

In recent months, Boskalis deployed the trailing suction hopper dredger (TSHD) Gateway and the backhoe dredger Manu-Pekka to the North Sea to make preparation work for the installation of the 22-kilometer-long offshore pipeline by Allseas.

Boskalis said that they, in cooperation with its partner Allseas, worked hard earlier this year to prepare one of gas fields for a second life as an offshore CO2 storage facility.

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,” said Boskalis.

“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.

According to Boskalis, two long spool pieces were then fitted to the riser.
