As part of the establishment of the 130-kilometre-long ‘Skagerrak 4’ HVDC cable between Norway and Denmark, Sørmaskinering AS built a converter station in Kristiansand. CSK provided all the steel structures for the project.
During the construction of the HVDC converter station for Skagerrak 4, the contractor, Sørmaskinering AS, chose to have their own staff handle installation. And while CSK normally delivers complete solutions, where we plan, design, produce and install the structures, it was no problem for us to work with the contractor’s choice. Our steel components are always complete assembly kits with bolted joins, and therefore easy for the installers to handle.
We used about 570 tonnes of steel for the construction of the converter station, much of which had to be fire painted.
Fire painting structures is not a complicated task in itself. In this case, however, the structures were relatively large, and since repairing damage to fire paint is quite costly, it was therefore necessary for us to take some technical precautions. We therefore welded lifting lugs on the fire-painted structures to avoid damage from straps, and we paid close attention to the packaging in order to avoid contact abrasion.
