DARWIN ABATTOIR SITE PRESENTED BY

AIRDUCTER TEAM

GENERAL OVERVIEW Airducter was required to dismantle an existing gas driven cogeneration system in Toowoomba and relocate to the new Darwin Abattoir site in the Livingstone Valley. The system will provide 3.9MW of 3 phase electricity and 22 L/S of 85˚C tempered hot water and 850kpa steam to the main operating facility. Reliability of the gas supply is approx. 2% downtime with electricity having 8-10% downtime.

GENERAL OVERVIEW Production phase will be: • 1 shift 520 head per day – 100% of one genset

and 50% of the second genset (2MW required) • In time (12 months) 2 shifts of 1040 head per day

– 100% of 3 gensets (3.9MW) Airducter is not responsible for the day-to-day running of the abattoir and if there are any questions relating to this it can be directed to Dave Gurran during question time.

SCHEMATIC

TRIALS & TRIBULATIONS • Approval had to be sourced from Toowoomba

Regional Council for development approval for building works (dismantling). Included fee application.

• Our OHS had to comply with both NT and QLD legislations. Site inductions included venomous reptiles.

• Railway adjacent to the Toowoomba job site with coal trains passing daily limiting access - every 1 hour (24 trains per day)

• Latent conditions on site – access for heavy machinery

• Site was an existing abattoir that had been shutdown for sometime which meant no power & water onsite.

• Switchboard corrosion issues were created by service trenches not having the ability to pump water out.

• Low loaders crossing the railway line with 32 tonne weight – only gave 50mm clearance
