The seventh expansion phase of the Dalrymple Bay Coal Terminal (DBCT7X) increased the terminal’s capacity by 50 per cent to a nameplate rating of 85 million tonnes per annum (mtpa), making it the third largest terminal in the world.
Aurecon Hatch provided full engineering, procurement and construction management (EPCM) services for the project which was delivered across three phases.
This expansion represented the largest construction programme in the terminal's history and significantly contributes to improving Australia's export capability.
The scope for the seventh expansion phase required careful integration of multiple disciplines and stakeholder requirements. The challenge was to design solutions to allow construction within an operational facility, causing minimal disruption to current activity. Detailed planning and shutdown coordination with the operation allowed for access to plant with minimal impact on terminal throughput.
Modifications and upgrades were delivered to all major inloading, stockyard and outloading terminal elements, including:
Adverse weather delays during the life of the project were minimised for the offshore works through the adoption of construction methodologies which limited the reliance on floating plant and equipment.
Aurecon Hatch, through parent companies Aurecon and Hatch, has been involved in every expansion of the terminal’s history, including the original berth design in 1982, and successfully completed the seventh expansion phase scope within a four year period.
