The transition from warship to artificial reef did not go smoothly for the HMAS Adelaide. Now roughly 100 feet below the surface, the popularity of the reefed ship has created new problems – a dramatic increase in the cases of the bends.
In 2008, the Australian guided missile frigate, HMAS Adelaide, was decommissioned. In 2009, plans were underway to sink the ship as an artificial reef off New South Wales. This was delayed by opposition from environmental groups which claimed that the ship still contained toxic materials. After lawsuits, mediation and further removal of wiring and insulation from the ship, HMAS Adelaide was finally scuttled on April 13, 2011 off Avoca Beach, New South Wales, in 32 metres (105 ft) of water. Now, medical experts are reporting a record high number of divers in New South Whales suffering from decompression sickness, often referred to as the bends, due to diving on the wreck.
