Power Station Decommission and Turbine Resale
Decommissioning of Power Station
AJSS oversaw the entire decommissioning process of a major gas power station, including dismantling equipment, removing systems, and preparing the site for reuse.
Turbine Resale Evaluation
AJSS conducted a desktop study to assess the resale potential of the turbine engines, determining the economic value and providing recommendations for resale.
Turbine Dismantling and Packaging
The team dismantled the seven turbine packages, carefully deconstructing components such as the enclosure, gearbox, lube oil systems, blades, and other critical engine parts while ensuring minimal wear for resale.
Removal of Auxiliary Systems
AJSS removed and disposed of all auxiliary systems, including air compressors, pumps, tubing, and redundant waste material in preparation for demolition.
Site Demolition
The project included clearing and demolishing redundant plant equipment, restoring the site to a bare-earth condition, ready for repurposing.
Safety and Compliance
AJSS conducted the entire decommissioning and resale process in strict adherence to safety standards, using Safe Work Method Statements (SWMS) and detailed risk assessments to ensure the safety of all personnel.
Project Management
AJSS provided full project management support, ensuring the project was completed on time and within budget, with all phases carried out to the required specifications.

Brief
- 7 gas turbine packages dismantled and preserved for resale
- 12-month end-to-end delivery (June 2022 – June 2023)
- 4 AJSS specialists delivering all project phases
- 100% site remediation, returned to bare-earth condition
Situation
AJSS undertook works to oversee the complete decommissioning of a major gas power station. The station was to be replaced with an integrated renewable and thermal energy generation system, but this system is yet to be constructed. AJSS completed the full scope of works, from the initial desktop study into the viability of the turbine resale, to the decommissioning and demolition of the entire power station site.
Task
The initial scope of the project began with a desktop study and later evolved into AJSS leading the multi-phase decommissioning project to completion. The project phases undertaken included a desktop study, dismantling of the packages, decommissioning of auxiliary systems, demolition of site and sale of turbine engines. The goal was to dismantle and decommission the in-situ engines, packaging them appropriately, ensuring limited wear or damage to the system, to allow resale of the turbine packages.
Action
After the initial study, AJSS set to the timely dismantling of the 7 turbine packages. The team deconstructed all aspects of the system including the enclosure, lube oil system, blades, gearbox and all other engine components. During the decommissioning phase AJSS looked to remove all auxiliary systems required before the demolition of redundant waste material and systems. This includes the draining and disposal of diesel fuel and other substances, and the disassembly of air compressors, pumps, tubing and the disconnecting of systems in preparation for demolition. The demolition phase of the project consisted of deconstructing and clearing any remaining, unwanted plant equipment to return the site to the required bare earth state. All phases of the project were actioned in accordance with OHS laws, regulations and the AJSS safety policy. Conducting comprehensive Safe Work Method Statements (SWMS) and prioritising safety first throughout all works to ensure minimal risk to all personnel and reduced likelihood of HSSE incidents.
Result
The project was executed efficiently and in a timely manner, allowing project completion well within the allocated timeframe and budgetary requirements. Demolition works concluded in August of 2023, with the site being levelled to a bare earth state, leaving the site in the conditions as inherited by the customer before initial construction of the power station. This project highlights AJSS’ capability to manage complex, multi-phase projects from inception to completion, showcasing our comprehensive understanding and structured approach to project management, and the decommissioning of end-of-life rotating machinery and auxiliary systems.
