BY THE NUMBERS Dalrymple Bay: Award-winning terminal expansion $1.26 billion capital cost 56 % increase in capacity 85 Mtpa upgraded terminal capability When the award-winning Dalrymple Bay Coal Terminal’s (DBCT) seventh expansion concluded, the capacity of the terminal was increased by 56 percent from 54.5 million tonnes per annum (mtpa) to 85 mtpa, making it one of the largest export terminals in the world. Under Hatch’s leadership the Aurecon Hatch JV provided full engineering, procurement, construction and project management services. The $1.26 billion project had a total of 5.5 million hours worked and more than 21,000 audits of safety protocols. The DBCT project won the 2010 Queensland Engineering 18
Excellence Award. A year earlier the project captured a Facilities Excellence Award. Engineering design excellence produced: • Automated wagon vibrators that eliminate manual handling and noise-related occupational health and safety hazards • Jetty widening on a single row of vertical piles to ensure the benefits of lower capital cost, smoother constructability and easier maintenance • Further expansion accommodated by the jetty widening and the vertical pile structure • Processes that allowed full production being achieved within days of startup • An enhanced working environment that is cleaner, provides good maintenance access and is less constrained for operational personnel. At program completion, a distinguishing operational feature of DBCT was the technology of two reclaimers simultaneously feeding each outloading conveyor/shiploader. This feature enables DBCT to efficiently blend cargoes out of the stockpiles which have enhanced terminal users' commercial positions in global markets. The DBCT 7X project scope of work included the introduction of 3D anti-collision technology that increased the advantage of cargo blending. In addition to the innovative higher bund walls in the stockyard, greater capacity, efficient blending and simultaneous machine operation, is only part of the engineering components that have placed DBCT as the highest throughput coal export terminal in the southern hemisphere Hatch Advantage July 2011 | 19
