Subsea Infrastructure: Challenges & Solutions

As offshore oil and gas reserves become ever more difficult and costly to recover, the demand for innovative technology has never been greater. Joe Orrell, managing director at RED Engineering, considers some of the challenges in subsea infrastructure design and the role of fast track engineering solutions.   The offshore oil and gas industry, even in times of low prices and abundant supply, is driven by the almost relentless search for new fields to replace those coming towards the end of their natural productive lives. Often this forces exploration in ever more challenging environments and

Fugro won a contract to install a subsea power cable for South Australia’s distribution network management company, SA Power Networks. The new 20,000 kVA/33,000 Volt cable will replace the existing 10,000 kVA/33,000 Volt undersea cable, which is reaching the end of its life. The subsea asset is a continuous 15-kmlong cable, weighing 600 tonnes and 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
