Saltire & Beatrice roadmap of savings from warm stack to NNA mode
‣ Optimize management of maintenance and integrity fit for Post CoP asset purpose allow massive reduction on safety critical and overall backlog
‣ Improved risk profile of assets by reducing personnel exposure by converting the platforms to Normally Not Attended mode of operations
‣ Using Enabling Technologies and Digital Solutions to enhance operations management of Post CoP assets
