The backbone of the automated reporting and monitoring system for all 4 lighthouses will be the ICSS – Integrated Control and Safety System. 2.0 VISUALISATION AND AUTOMATED REPORTING SYSTEM The most important chain for achieving any digital workable success is the data accuracy collection process. It’s the vital parameter of a data-driven bases and systems. They are usually scattered throughout diverse company places in many different formats from significantly various data sources. Each of these different and compiled data sources come with their own unique management challenges and their own complex subsystems and play an important role in an organizational infrastructure. Automated reporting system (ARS) will combine all those complex data sources together in one centralized system where data will be sent, received, and transformed into a controlled environment and stored. Data will be collected at regular intervals predefined with agreed frequencies: - The real time approach is used for the field smart equipment and sensors - Daily frequency is used for parameters such as but not limited to the daily hydrocarbon production, maintenance, safe work and process safety and alarms reporting - Data validation will be followed by the RACI chart defined in this scope Real-time data collection will be done using a data collection module, which requires configuration for the Rozhkovskoye field environment. Module can collect enormous amounts of data from any data source invulnerable to various cyber-attacks. Modules will be connected directly to ICSS/SCADA system and/or any other operating servers in safe environment. Every data parameter will be available on real-time dashboards and the selected ones on historical trend chart. There will be an option of the informative data availability on the smart and portable devices. Real-time dashboards will be available in the CCR (Central Control Rooms/Collaborative Control Room) designed to facilitate the control and monitoring of production and operations. Business processes will be steered by the RACI chart decision tree translated into the ARS model and further providing focused operational excellence services. The associated business processes determine how certain data will be captured and processed through process workflows and the RACI matrix. In case that Rozhkovskoye field will be throught the 3D model operable, the integration with it will be available as well. 3.0 INTEGRATED MAINTENANCE MANAGEMENT SYSTEM For attainable asset performance monitoring, the deployment of the predictive, preventive and corrective maintenance solutions to provide safe operation, monitor equipment health, schedule maintenance activities, and minimize downtime will be the key factors.
