The Dalrymple Bay Coal Chain is a major coal export network for the Bowen Basin located west of Mackay in Queensland. It is a part of the greater Goonyella Coal Chain that involves 22 producing coal mines owned by nine different producers, over 300km of track, two above rail providers and two coal terminals that export through the Port of Hay Point.

The fragmented ownership and operating structure of the Dalrymple Bay Coal Chain has meant that the coal chain faces a range of communication and operational issues. One key issue in particular is a historical lack of alignment in the Master Planning, focussed on a 2 – 10 year time horizon, of the coal chain. This lack of co-ordination has resulted in mismatches in system component capacities and a mistiming of upgrade steps. 

A simulation model has been developed to support the Master Planning process of the Integrated Logistics Company (ILCO) and the Office of the Central Co-ordinator. This model extends from the mine load-outs through the rail and terminal operations through to the arrival of ships in the Port of Hay Point. This model also includes interactions of the Dalrymple Bay Coal Chain with other systems including the Hay Point and Blackwater systems as well as a range of non-coal traffic on the railway. 

The model provides the independent and transparent decision support tool to underpin the Master Planning process for the supply chain as a whole. It allows the quantitative evaluation of system capacity for different capital and operating scenarios in a whole of system context. This allows the most capital efficient solutions to be developed for the system. It also reduces the risk that the system as a whole fails to deliver when each component is designed in isolation and ensures that when it is built, the integrated system performs as expected.
