By 1928 the dredge Parmelia, built in Renfrew, Scotland, in 1896, had become old and not worth repairing. For some years the hull of a new dredge had been under construction by the State Implements Works, and in late 1928 the two dredges were moored side by side while the machinery from the Parmelia was transferred to the new hull. The stripped hull of the Parmelia was then towed to the Ships’ Graveyard off Rottnest Island and scuttled. The new Parmelia had two boilers each weighing about 20 tons to provide steam to the engines that had been transferred from the original dredge. The Parmelia commenced work in Fremantle Harbour on 27 February 1929. In the early 1950s the Parmelia was sold to Dredging Industries of Australia who converted it from a bucket to a suction dredge, and renamed it D9.
