Nexans’ Direct Electrical Heating (DEH) cable systems will be installed to help in maintaining the reliable flow of products from the Shah Deniz field, located in the Azerbaijan sector of the Caspian Sea. The world’s largest DEH project to date will see Nexans deliver a total of 130 km of the cable system to provide flow assurance for 10 subsea flow lines. The contract is worth approx 100 million Euro.
DEH systemThe DEH systems, including riser cables, piggy back cables and accessories, will be designed, engineered and manufactured at Nexans’ specialized subsea cable and umbilicals facility in Halden, Norway.
