A well-executed mobilisation of operation and maintenance (O&M) services creates a foundation for operating a power plant successfully long into the future. Decisions made in this phase define the working parameters for the O&M organisation. Every project is unique but it pays off to have standardised steps and process for mobilising a greenfield power plant. The presentation introduces this process and the key elements of a successful O&M mobilisation, and lists capabilities required from a competent O&M provider.
