The new 20,000kVA/33,000V cable will replace the existing 10,000kVA/33,000Volt undersea cable, which is reaching the end of its life. The continuous 15km-long cable, weighing 600t, connects Kangaroo Island to the distribution network on the southern Fleurieu Peninsula, south of Adelaide.
Fugro will design and supply the power cable and will use its multi-role support vessel, REM Etive, to install it across Backstairs Passage, from Fishery Beach on the mainland to Cuttlefish Bay on Kangaroo Island. After installation of the cable, Fugro will also carry out commissioning and associated termination and connection works. Client for the contract is South Australia’s distribution network management company, SA Power Networks.
Project operations are are scheduled to begin during the last quarter of 2017 and take a couple of weeks. The new cable is expected to be operational by the middle of 2018.
