Demolition without Disruption

Leading industrial demolition and remediation contractor, Liberty Industrial, recently completed a multistage coal handling infrastructure demolition project at Port Kembla Coal Terminal. Achieving minimal disruption to the operational coal terminal facility was critical to the success of the project.

Liberty Industrial was initially engaged to dismantle a redundant stacker and reclaimer to make way for new machinery and have since dismantled a further two stackers and another reclaimer at the terminal. The works formed part of a broader terminal restoration project.

These works have earned Liberty Industrial a place as a finalist at the World Demolition Awards on two occasions. The first stage of works earned Liberty Industrial a place as a finalist at the World Demolition Awards in the Industrial Demolition award Category and the second stage saw Liberty Industrial nominated as finalist in the Contract of the Year award category.

Typically, a complete shutdown of key operational assets, such as coal conveyors, bunkers and ship loaders would be required for a demolition of this nature, however, Liberty Industrial’s approach enabled all preparatory works to be carried out with minimal disruption to the coal terminal’s operations.

A 1,250 tonne bucket-wheel reclaimer was transported using a custom built structural steel support frame mounted on Self-propelled modular transporters from the operational coal terminal to a dedicated demolition area. Once the structure was safely positioned in the processing area it was preweakened in order to facilitate explosive demolition with cutting charges. Explosives were used to safely reduce the structure to suitable height for mechanical processing.

Next, a 400 tonne stacker was dismantled insitu, over live operational conveyor lines utilising a large crawler crane. The stacker was dismantled in a choreographed sequence designed to maintain the structural stability of the structure. Sections of the stacker weighing up to 140 tonnes were rigged to the 600 tonne crawler crane, separated from the stacker and lifted down for downsizing and removal.

In the second stage of the project, Liberty Industrial carried out the demolition of another 1,250 tonne bucket-wheel reclaimer and another two 400 tonne stackers that had been made redundant following the commissioning of new coal handling equipment.

Liberty Industrial once again developed a methodology to enable all preparatory works to be carried out without disruption to terminal operations.

Once disconnected from their electrical power supply and ancillary services, the three machines were progressively dismantled in a choreographed sequence designed to maintain the structural stability of the structures.

Liberty Industrial carried out the dismantling in the stockyards using a 750 tonne crawler positioned directly adjacent to each structure. Sections of the structures weighing up to 220 tonnes were rigged to the 750 tonne crawler crane, separated from the remaining structure and lifted down for processing and removal.

With demolition occurring within close vicinity to operational coal handling infrastructure, intelligent engineering and extensive planning and coordination were key to the successful completion of the works with minimal disruption to the terminal’s operations.
