The company is supplying 10 of its new controlled flow transfer systems to the RG Tanna Terminal at Gladstone, Queensland, as part of an upgrade of the facility’s in-loading system to handle 6000 tonnes per hour of bulk material. Tasman-Warajay managing director Mick Wordsworth said the project included the design, supply and installation of two three-way diversion systems for the terminal’s main distribution tower, and a dump station transfer. The company had to work within restrictive height constraints.

“The capability of Tasman-Warajay to develop workable solutions within these constraints had added significant value to the project,” Wordsworth said.

At Dalrymple Bay Coal Terminal, also in Queensland, the company is designing and supplying two two-way diversion controlled flow transfer systems for a current expansion project, while a further two offshore two-way diversion systems are being designed for a future expansion project. Tasman-Warajay is also supplying three reclaim centre chutes for two stacker/reclaimers and a reclaimer at the DBCT.

Wordsworth said the lower impact cradle of each chute was removed to allow direct loading onto a yard conveyor, and central loading of the yard belt in all quadrants. “These systems have been specifically designed to meet the very high environmental standards at the Dalrymple Bay site,” he said. “The terminal has set very high standards in terms of total containment of dust and spillage at their transfer locations. In our opinion, these standards set a new benchmark for the Australian coal industry.”

Wordsworth said Tasman-Warajay controlled flow transfer systems had been installed at Queensland’s three major coal terminals on the basis that they offered “significant operational advantages”

“Tasman-Warajay designs are well outside conventional and accepted coal handling design parameters,” he said. “We have developed design technology which allows the accurate prediction of material behaviour within a conveyor transfer system, and subsequent control of the material’s direction and velocity through the transfer process.

“This approach eliminates or substantially reduces a lot of the traditional problems associated with material transfer such as dust, noise, material degradation, excessive wear and spillage.

“Our controlled flow transfer systems are based on this design technology.”

Established in 1993, Tasman-Warajay manufactures its equipment at Gladstone. The company has 25 employees.
