was reduced. On 10 June 2005, Rankin became the first submarine since in 1987 to receive the Gloucester Cup, an award presented to the RAN vessel with the greatest overall efficiency during the previous year. The award was subsequently presented to Sheean in 2006, and again to Rankin in 2008. In March 2007, Farncomb had an emergency when crew were washed overboard while attempting to remove fishing line from the propeller. The boat was reportedly conducting surveillance on Chinese Navy submarines in the South China Sea. In 2008 and 2009, personnel shortages reduced the number of submarines able to be deployed to three; the maintenance cycles of Sheean, Rankin, and Dechaineux, and problems with Collins and Waller further reducing this to one, Farncomb, in mid-2009. Farncomb was docked for repair after a generator malfunction in February 2010, by which point Collins and Waller were active (the former on limited duties because of defects), and Dechaineux was slated to re-enter service by May 2010. Workforce shortages and malfunctions on other submarines during the preceding two years impacted heavily on the maintenance of Sheean and Rankin, with RAN and ASC officials predicting that they would not be active until 2012 and 2013, respectively. In June 2011, The Australian newspaper claimed despite two submarines (Waller and Dechaineux) designated as operational, neither was in sailable condition. The initial findings from the Coles Review revealed significant, systemic problems with the submarines and noted the need for their management to be reformed. A 2014 statement by Vice Admiral Ray Griggs indicated that up to four submarines had been operational on most occasions since 2012. Replacement The submarines originally had a predicted operational life of around 30 years, with Collins to decommission around 2025. The Submarine Institute of Australia released a report in July 2007 arguing that planning for the next generation of Australian submarines had to begin soon. In December 2007, shortly after the 2007 federal election, the Australian government announced that planning for a Collins-class replacement (procurement project SEA 1000) had commenced. The 2009 Defending Australia in the Asia Pacific Century: Force 2030 white paper confirmed the replacement project, and announced that the submarine fleet would be increased to twelve vessels to sustain submarine operations in any conflict, and counter the growing potency of Asian-Pacific naval forces. The 2009 white paper outlined the replacement submarine as a 4,000-ton vessel fitted with land-attack cruise missiles in
