Wiggins Island Coal Export Terminal
Client: Department of Water, Monadelphous, Stockland
Capex: $2.5 billion AUD
Location: Gladstone, Queensland
Completion Date: 2011
Project Details: Once fully commissioned the coal export terminal will double the coal export capacity at the port. The first coal shipments through stage one of the terminal are planned from late 2014. Stage one construction includes rail receiver facility, overland conveyors, stockyard areas for 1.9 million tonnes of coal, materials handling and sampling station, single berth, wharf and substation.
Scope of Work: DBM Vircon's scope included the design and detailing of the lifting frames for the “undressed” east and west Stacker Bridge, stacker legs, central carriage and tripper for inshore lifting of the bridges from port in China onto the transport ship and onto port in Australia into position for Sinostruct. The stacker bridge lifting study included the design and detailing of the lifting frames for the stacker bridge.
DBM Vircon then carried out the Transportation Study and Temporary supports for John Holland to modify the design of the frame to allow the bridge to be transported over land provide supports while the bridge is dressed and allow lifting of the fully dressed bridge into final position.
Highlights & Challenges: The Stacker Bridge featured in an article Monster lift puts 125 metre-long bridge in place at WICET in the Gladstone Observer on the 27th May 2014.
“The largest individual structure to be built at the Wiggins Island Coal Export Terminal has been successfully lifted into place at the WICET coal stockyard. The 780-tonne lift and installation of the western stacker bridge was completed…Work began with 750 and 1100-tonne cranes lifting the bridge structure into place, 25 metres above the stockyard floor. The stacker bridge is 11 metres wide and 125 metres long, and will comprise an integral part of the terminal's coal in-loading infrastructure, providing the support and housing for the shuttling conveyor and telescopic chute which will deliver coal across the stockpiles.”
