PDO Qarn Alum Power Station Commissioning Phase 1 & 2

The power station was a 250MW simple cycle. Our engineers supported PDO in managing the third party interfaces to ensure all the equipment, subsystems and switch boards communicate and function as per specification through DCS system to the central control room. With the electrical discipline lead, the completion plans were managed to drive safe start-up of all subsystem.

Scope of work

    Power station completion system, Pre-commissioning and commissioning as part of the PDOs commissioning team.
  • Commissioning - Our engineers commissioned systems such that they conform to the design specifications in a safe manner. We produce and work to approved commissioning procedures and take accountability for delivery. Our commissioning services have been delivered at the start of the project and where agreed with the clients having a great input into project front end loading which ensures a commissionable, operable maintainable design is engineered. With the increased automation in power generation and electrical substations, our high level of expertise in instrumentation and control complements the electrical team in overall delivery.
  • Electrical Testing - Our experience has taught us that structured testing methodologies are critical for a safe and compliant energisation. Our Relay Test Engineers executed the testing and validation of all protection setting in addition to the overall protection schemes maintaining an audit trail for the staged witness and acceptation from the check sheets all the way to the handover certificates.
