Cofra provided ground improvement support during the cable route preparation works associated with the Borssele offshore grid connections (including the Beta connection that links Borssele 3 & 4 to the onshore high‑voltage grid). After seabed surveys identified that soil conditions in the De Honte navigation channel differed from tender-provided data, there was concern that embankment instability could affect the integrity of the installed cables. To address this risk, Cofra was brought in to compact the seabed using vibro‑compaction techniques. The work was carried out from a crane pontoon with long working hours to strengthen and stabilize the soil in the affected corridor prior to, and in support of, cable installation and protection measures. This intervention formed part of a broader package of seabed preparation activities along the nearshore and fairway sections, undertaken to manage challenging depths, variable ground conditions and heavy maritime traffic constraints in the Western Scheldt area. The described scope is directly linked to safeguarding the cable system by improving the ground conditions around the export cable route, thereby reducing the likelihood of seabed movement and subsequent cable damage over the operational life of the connection. No contract value or award date for Cofra’s specific scope was stated in the cited source.
