Kwinana Cogeneration Plant
Engie is a global energy company focusing on low-carbon energy solutions. In Western Australia, Engie operates the Kwinana Cogeneration Plant, a key Kwinana Power Station complex facility. The plant, owned by the Synergy Power Corporation, provides both electricity and steam, serving nearby industrial customers while contributing to the region’s energy reliability and sustainability.
Duct Balloon is used to protect gas turbine during temporary shutdown
Engie needed a solution to preserve the condition of a Gas Turbine during a temporary shutdown caused by reduced energy demand, allowing for an eventual restart with just 24 hours’ notice. To prevent corrosion by keeping the turbine warm and dry, Engie sought a cost-effective method to block airflow through the boiler’s exhaust stack. Giant Inflatables Industrial responded by designing and fabricating a custom duct balloon similar to those used in Combined Cycle Gas Turbine plants. This duct plug, deployed from the stack’s landing, provided an efficient and flexible way to maintain the turbine’s condition while minimising costs during the uncertain operational period.

Double Block and Bleed Duct Isolation System
The double block and bleed system is commonly used for isolating power station ducts and ventilation systems during maintenance and repairs.
Inflatable Isolation Duct Cushion
The isolation duct cushion ensured that if there were any faults with the stack damper, the inflatable duct barrier would prevent downdrafts.
