PDO decided to upgrade the old Birba Cluster and started with a FEED and Detailed Design done by Abalto with WPAI for PDO. From the FEED stage, the project entered in detail design phase and commissioning and Start-up where again Abalto was awarded the specialist role of System Integrator SI for the hot swap changeover and commissioning of the Automation, Control & Instrumentation for the Control and Safety Systems upgrade.
