The Soundcem II & III self-propelled barges were built in South Coogee, Australia and are all fitted with 268kwCaterpillar engines. The Soundcems have a maximum payload of 348 m3 each and are purpose designed to transport dredged material from the dredged site to the disposition area with maximum productivity. Each split hopper is hydraulically operated for maximum reliability and improved cycle time turnaround. Their shallow draught and flat bottoms enables them to be used in shallow river environments. The port and starboard halves of the Barge operate by splitting longitudinally between the end bulkheads and a typical dump only takes 20 seconds.
