Combined-cycle Maintenance: Defining the Work Scope

Combined-cycle maintenance enquiries need a clear description of the equipment and the work required. A plant-wide request is easier to assess when it separates the gas turbine, steam turbine, generator, control systems and supporting equipment.

Define the equipment and interfaces

List the manufacturer, model and identification of each asset. Explain whether the requirement concerns inspection, repair, parts supply, installation or commissioning. Identify work that will be performed by the plant team or another contractor so that responsibilities can be agreed.

Build the enquiry package

• Equipment records, drawings and available maintenance history.
• The reported issue, relevant observations and previous repair reports.
• The proposed outage window, site location and access requirements.
• Parts already available and items requiring procurement.
• Requested inspection records, test documentation and handover deliverables.

Agree the scope before the outage

The inspection findings and agreed technical requirements determine the final repair or replacement scope. Schedule, supply condition and acceptance requirements should be confirmed for the specific assignment.
