The new $1.6 billion, 60,000-seat Perth Stadium is a world-class venue capable of hosting AFL, rugby union,
rugby league, soccer, cricket and entertainment events.
Encased in a sleek metallic sheath that rises out of an impressive park setting on a bend of the Swan River at Burswood, the stadium – Australia’s third largest – will be officially opened in January 2018.
The commitment to a ‘fans first’ stadium includes two giant 340 sq m video screens, more than 1000 TV screens throughout the interior of the complex, over 50 food and beverage outlets, and state-of-the-art LED lighting to show home team colours at night on the external façade and roof canopy.
The five-tiered stadium – its striking bronze façade reflecting West Australia’s geology – sits on 2000 concrete piles driven to a depth of up to 35 metres and was under construction from late 2014 till October 2017.
High-output Cummins power.
Hidden in the bowels of the stadium are four Cummins generator sets. At the heart of the stadium’s emergency power system, they have a standby rating of 1.8 MW at 1500 rpm and are powered by one of Cummins’ most widely-used high-output diesel engines globally – the QSK60, a 60-litre V16.
Nilsen, the head electrical services contractor for the stadium project, selected Cummins to install the generators sets, exhaust system, fuel system and room acoustics, as well as carrying out the commissioning.
Proven product reliability along with technical and aftersales support were key reasons for Cummins being awarded the job, according to Cummins Perth sales executive Bhavani Sambhara. “Nilsen and Cummins have a close working relationship as a result of a number of successfully executed projects,” says Nilsen WA operations manager Mark Cassady. “Cummins’ technical and service support is highly respected and the company is quick to respond if there are any issues.”
Prior to the Perth Stadium project, Cummins and Nilsen successfully delivered the emergency power system at the Perth Children’s Hospital. Complex but successful project. Rukmin Rathnasinghe has headed up the successful stadium project for Cummins Perth, managing a complex stakeholder environment that included Nilsen, Brookfield Multiplex (builder), and Wood & Grieve Engineers (project consultant).
The four Cummins generator sets – C2250D5 (QSK60) units – are split between two substations, each substation delivering power to half the stadium. One generator in each substation can cater for 100% of the section power requirements in the event one unit fails, providing an N+1 redundancy.
The generator capacity also allows the stadium to be operated purely on the generators when needed, easing the demand on the local electrical utility.
In the event of a power outage, both generators start automatically and operate in parallel to supply emergency power to the stadium. The Cummins PowerCommand controllers continuously monitor the generators and provide status signals to the stadium building management system. They provide the added benefit of signalling an overload on the generators to shut down the non-essential equipment during critical situations.
Each substation has one 7000-litre bulk fuel tank providing nine hours of operation at 100% capacity, while two 1000-litre day tanks are also installed at each substation. One fuel system controller per substation provides a control centre for the fuel transfer pumps, solenoid fuel valves and tank alarms. All the alarms are interfaced with the building management system.
Primary and secondary mufflers meet the room acoustics requirements of 65 dBA at specific locations outside the generator substations. Catalytic converters are installed inside the primary muffler to reduce the overall emission levels.
Value of teamwork.
The value of teamwork has been clearly evident at Perth Stadium from a Cummins Perth standpoint. In addition to senior project manager Rukmin Rathnasinghe, other key members of the Cummins team have been lead engineer Boon Hong who provided excellent technical support from the tendering to the commissioning phase; lead commissioning technician Aek Chatnund who successfully led a team that included Jon Beazley and Koen Redfern; and supporting project manager Shahan Jerejian who provided valuable contributions on the exhaust system design/building integration.
