Corrosion and vibration slow Gold Coast commissioning
The progress of the Gold Coast seawater reverse-osmosis (RO) desalination plant in Queensland, Australia, towards its commissioning targets has been slowed by several problems, which are now being addressed.In a statement on 13 January 2009, Paul Lucas, Deputy Premier and Minister for Infrasture & Planning for Queensland, said that the most pressing problem was the early corrosion apparent in 45 pipe-couplings in the RO section. He stated that Water Secure, the state government body that will ultimately own the Aus$ 1.2 billion (US$ 815 million) plant, will not take it over until these and other faults are fixed.
Other problems identified during commissioning include:
"The best replacement parts are being established now and work will begin as soon as possible," said Lucas. "But ... we are talking about work that could take several months; some of these parts are custom-made."
The 125,000 m³/d plant is now aiming at 33% production by 5 February 2009 and 100% by 20 February.
