Synergy’s second-largest power station has four turbines driven by steam from boilers fired by coal, natural gas or fuel oil, and one gas turbine. Together they generate a total of 420 megawatts of electricity.
The station was originally built in 1970 as an oil-fired power station, however it was later converted to coal due to the rising price of oil caused by the 1973 oil crisis. This project received an ‘Engineering Excellence Award’ from the Institution of Engineers Australia in 1980. The KPS facilities were progressively decommissioned between 2009 and 2015. Due to the age of the facilities the integrity of the cladding that contains the thermal insulation material on the boilers, precipitators and connecting infrastructure has degraded.
This project has been initiated to mitigate the dangers of sheet metal detaching and falling to ground and to prepare the facilities for demolition. This work will ensure Asbestos Containing Material is either removed or identified to enable the safe demolition the facilities.
Scope of Works
This Scope of Work incorporated the removal of all insulation and cladding within the battery limits of the power station. The scope included for the provision of all required management, labour, materials, equipment, services, site facilities, access, testing, and waste disposal. It also included for the provision of all documentation, methods and procedures to undertake the works in a safe and efficient manner.
Cladding and insulation removal included all metal sheet cladding, offset cladding support channels, fixtures, gasket material and all insulation material that was contained behind the cladding. All surfaces that were exposed as a result of the cladding and insulation removal were cleaned, tested and verified free of ACM residue.
The boiler and precipitator structures were substantial in size and complexity standing 40m+ tall and were made up of large cladded cavities which are connected together with elevated ducting and pipework. Stages also included Steam Turbine Generators, Feedwater heaters as well as various insulated steam and water interconnecting pipes.
