UK-based engineering and technology company Osbit has completed work on a standby system for emergency repairs of critical subsea power cables in South Australia.
Osbit said the new Quadrant Handling System— for electricity distributor SA Power Networks— is a mobile containerised system that can be deployed and installed on a repair vessel in the event of a cable fault “to ensure power can be restored quickly and efficiently”.
“The system comprises lay chutes, cable quadrant, quadrant trackways and cable roller units, which are supplied in a modular assembly arrangement,” Osbit said.
Managing director Brendon Hayward said: “This innovative system will help support prompt repair as well as mitigate cost pressures caused by a subsea power cable fault. As a containerised unit, it can be deployed through standard shipping lanes rather than costly bespoke delivery, which ensures rapid mobilisation so that offshore technicians can carry on the required repairs in as short a time frame possible."
Hayward said: “As a standby spread, the low impact sea fastenings permit the repair vessel to operate as usual, whilst permitting quicker response to a cable repair with no further class involvement.”
SA Power Networks is the sole electricity distributor in South Australia— using a network of power lines including critical subsea cables supplying Kangaroo Island, off the coast of the state capital Adelaide.
South Australia has seen a wave of investments in critical power infrastructure in the wake of a state-wide blackout in 2016.
