Jan De Nul connects Tennet's power grid in the Netherlands and continues to invest in its offshore installation fleet

Brand Studio for Jan De Nul

Jan De Nul Group completed the first part of the installation work for Tennet's offshore power grid cables that will connect the transformer stations of the Hollandse Kust North and Alpha West wind farms to the Dutch mainland. Each of these stations will receive two cables, with a total length of 235 kilometers.

In line with the objective of further enhancing its offshore installation capabilities, Jan De Nul recently entered into an agreement with UK-based Global Marine Systems Ltd. for the purchase of a new support vessel to be named Symphony. This new vessel will join those already in use in the area, such as the Isaac Newton cable installation vessel, amphibious cranes in the breakwater area and several remote-controlled underwater trenchers.

Within the framework of this project, the Moonfish trencher, designed and developed by the Belgian firm especially for this project, stands out, which at this stage buried the first section of the two Hollandse Kust (noord) marine cables in the seabed, from the beach up to 3 kilometers offshore at a depth of about 6 to 8 meters. Simultaneously, this powerful equipment allows immediate backfilling of the created trench, thus protecting the cables against future coastal erosion and making the task a success.

Once the wind farms are operational, they will produce enough green energy to power one million homes per year. Considering the outcome of this project, the company is very proud to be part of an initiative of this nature that will produce renewable energy from the use of its innovative fleet.

This same Jan De Nul technology is available in Argentina and throughout the region for large-scale projects that require complex works at sea, and is currently present in the first generation vessels that carry out dredging and maintenance tasks in ports, access channels and river routes in Argentina.
