Dragline Forty-One (DRE41) is an 8200 Marion dragline that was relocated from the USA for use at the BMACO Blackwater Mine, open cut pit, near the township of Blackwater in Central Queens- land. It is the second machine of this size to be introduced to the Blackwater pits. This is the sec- ond me this machine had been relocated. Originally moved once in the USA, it has for the second me been cut up and this me shipped across the Pacific Ocean to the port of Mackay for transport across the range to Blackwater. Electrically the machine is virtually brand new. Every- thing has been upgraded or enhanced from the MG-Sets, main DC Motors, PLC gear and PCR. The electrical components on this machine were replaced from the older style hardwired relay logic to a fully automated and enunciated control system. Inete was engaged directly by BMA to provide complete electrical project management, a A$20m contract within the overall A$92m relocaon and reassembly project. . The electrical project in- volved a total redesign of the dragline’s enre on-board electrical and control systems employing state-of-the art technology, equipment and soſtware.

Project
BMA DRE41 Dragline Electrical Re-design and Re-location
Location
Blackwater Mine near Blackwater in Central Queensland.
Shutdown Works: The engineering task was to completely redesign DRE41’s on-board electrical, computer and control systems, to ensure compliance with Australian Stand-
ards and local Acts and Regulations governing such installations, and readying it for further automation.
The Inete contract with BMA required Inete to act as the Principal’s Representative and covered the scoping of all electrical work on the machine, budg-
eting and cost control, scheduling of procurement, manufacture, testing, installation and commissioning, tender management, procurement of all electrical
equipment, resource management, commissioning planning and control, software design and development, commissioning execution, shake down and
monitoring of the machine walk off and continuous improvement of its operation. Control of compliance with Australia Standards, Queensland Coal Mining
Act & Regulations and BMA Blackwater Mine Regulations were all the responsibility of Inete for the duration of the project, a very important role to ensure
proper conversion of the former U.S.A. 60 Hz electrics. Electrical safety on the machine; both during the installation and the final hand over and sign off by
BMA for site acceptance was the responsibility of Inete.
Key design features included a central programmable logic controller (PLC), the installation of more powerful DC motors and generators, comprehensive
and configurable data acquisition system, and a distribution system
designed to improve performance, reduce costs and enhance safety.
Project Close Out: Despite delays caused by the late delivery of the machine to Australia
in March 2006 - due to the effects of Hurricane Katrina in the U.S.A -
the electrical fit-out was completed on time and on budget in Decem-
ber 2006. Electrical staff were on-site for a further two months to
assist in testing while the mechanical contract was being completed
and to provide site support during the handover, training and initial
operational tuning period.
In 2007 Inete was awarded the Engineers Australia Queensland Divi-
sion Small Business Ventures/Projects award for its work carried out
