HMAS Stirling naval base is located on Garden Island, Western Australia. The diesel fuelling systems at the base consist of large storage tanks, fuel dispensing pumps and many valves located below the ship wharves. The tunnels feed power, communications, compressed air, sewage, water and diesel to and from the ships and submarines.
The major issues that needed to be addressed were the tunnels were considered ‘confined spaces’, requiring permits to gain access. A minimum of three personnel were required to conduct inspection or operation works. Also, the valves were separated by distances of up to 2km, which resulted in operational delays and operators needing to be at several different locations.
The Department of Defence commenced a project to move the point of valve operation to a common location outside the confined spaces, to make fuelling safer and to reduce both the number of personnel and the time required to fuel ships and submarines.
