BOKA Da Vinci supports North Sea CO₂ storage milestone

Boskalis’ diving support vessel BOKA Da Vinci has completed a specialised subsea campaign in the northern North Sea, delivering key infrastructure for an INEOS‑led carbon capture and storage (CCS) project at the Nini oil and gas field offshore Denmark.

​Working for INEOS as part of Project Greensand, Boskalis Subsea Services deployed saturation divers and a remotely operated vehicle to install a dynamic hose fitted with 49 buoyancy modules on the seabed in less than a month. After the dynamic hose was in place, the team positioned a pipeline end manifold with subsea precision before installing a static hose in two separate sections, completing the core subsea scope.

​The new subsea layout will enable CO₂ captured onshore to be transported by a dedicated bulk carrier to the Nini field, where the vessel will connect to the dynamic hose installed by Boskalis. Through this hose‑and‑manifold system, CO₂ will be injected into the depleted field for long‑term storage, supporting Denmark’s first full‑scale offshore CO₂ storage ambitions under Project Greensand.

​Boskalis said the campaign demonstrates how its established subsea decommissioning, inspection, repair and maintenance expertise can be repurposed to support emerging CCS and energy‑transition infrastructure in the North Sea.
